- Keep in mind building recent linux kernels with GCC will require ~20-25GB of disk space. Using llvm/clang, LTO, ccache and/or enabling more drivers in the defconfig will push that requirement higher, so make sure you have enough free space on the volume you're using to build.
|
||||
- In `intel_pstate` driver, frequency scaling aggressiveness has been changed with kernel 5.5 which results in stutters and poor performance in low/medium load scenarios (for higher power savings). As a workaround for our gaming needs, we are setting it to passive mode to make use of the `acpi_cpufreq` governor passthrough, keeping full support for turbo frequencies. It's combined with our aggressive ondemand governor by default for good performance on most CPUs while keeping frequency scaling for power savings. In a typical low/medium load scenario (Core i7 9700k, playing Mario Galaxy on Dolphin emulator) intel_pstate in performance mode gives a stuttery 45-50 fps experience, while passive mode + aggressive ondemand offers a locked 60 fps.
|
||||
- Nvidia's proprietary drivers might need to be patched if they don't support your chosen kernel OOTB: [Frogging-Family nvidia-all](https://github.com/Frogging-Family/nvidia-all) can do that automatically for you.
|
||||
- Note regarding kernels older than 5.9 on Arch Linux: since the switch to `zstd` compressed `initramfs` by default, you will face an `invalid magic at start of compress` error by default. You can workaround the issue by editing `/etc/mkinitcpio.conf` to uncomment the `COMPRESSION="lz4"` (for example, since that's the best option after zstd) line and regenerating `initramfs` for all kernels with `sudo mkinitpcio -P`

While PDS-mq got dropped with kernel 5.1 in favor of its BMQ evolution/rework, it wasn't on par with PDS-mq in gaming.

Subject: [PATCH] mm: vmscan: fix extreme overreclaim and swap floods
|
||||
|
||||
During proactive reclaim, we sometimes observe severe overreclaim, with
|
||||
several thousand times more pages reclaimed than requested.
|
||||
|
||||
This trace was obtained from shrink_lruvec() during such an instance:
|
||||
|
||||
prio:0 anon_cost:1141521 file_cost:7767
|
||||
nr_reclaimed:4387406 nr_to_reclaim:1047 (or_factor:4190)
|
||||
nr=[7161123 345 578 1111]
|
||||
|
||||
While he reclaimer requested 4M, vmscan reclaimed close to 16G, most of it
|
||||
by swapping. These requests take over a minute, during which the write()
|
||||
to memory.reclaim is unkillably stuck inside the kernel.
|
||||
|
||||
Digging into the source, this is caused by the proportional reclaim
|
||||
bailout logic. This code tries to resolve a fundamental conflict: to
|
||||
reclaim roughly what was requested, while also aging all LRUs fairly and
|
||||
in accordance to their size, swappiness, refault rates etc. The way it
|
||||
attempts fairness is that once the reclaim goal has been reached, it stops
|
||||
scanning the LRUs with the smaller remaining scan targets, and adjusts the
|
||||
remainder of the bigger LRUs according to how much of the smaller LRUs was
|
||||
scanned. It then finishes scanning that remainder regardless of the
|
||||
reclaim goal.
|
||||
|
||||
This works fine if priority levels are low and the LRU lists are
|
||||
comparable in size. However, in this instance, the cgroup that is
|
||||
targeted by proactive reclaim has almost no files left - they've already
|
||||
been squeezed out by proactive reclaim earlier - and the remaining anon
|
||||
pages are hot. Anon rotations cause the priority level to drop to 0,
|
||||
which results in reclaim targeting all of anon (a lot) and all of file
|
||||
(almost nothing). By the time reclaim decides to bail, it has scanned
|
||||
most or all of the file target, and therefor must also scan most or all of
|
||||
the enormous anon target. This target is thousands of times larger than
|
||||
the reclaim goal, thus causing the overreclaim.
|
||||
|
||||
The bailout code hasn't changed in years, why is this failing now? The
|
||||
most likely explanations are two other recent changes in anon reclaim:
|
||||
|
||||
1. Before the series starting with commit 5df741963d52 ("mm: fix LRU
|
||||
balancing effect of new transparent huge pages"), the VM was
|
||||
overall relatively reluctant to swap at all, even if swap was
|
||||
configured. This means the LRU balancing code didn't come into play
|
||||
as often as it does now, and mostly in high pressure situations
|
||||
where pronounced swap activity wouldn't be as surprising.
|
||||
|
||||
2. For historic reasons, shrink_lruvec() loops on the scan targets of
|
||||
all LRU lists except the active anon one, meaning it would bail if
|
||||
the only remaining pages to scan were active anon - even if there
|
||||
were a lot of them.
|
||||
|
||||
Before the series starting with commit ccc5dc67340c ("mm/vmscan:
|
||||
make active/inactive ratio as 1:1 for anon lru"), most anon pages
|
||||
would live on the active LRU; the inactive one would contain only a
|
||||
handful of preselected reclaim candidates. After the series, anon
|
||||
gets aged similarly to file, and the inactive list is the default
|
||||
for new anon pages as well, making it often the much bigger list.
|
||||
|
||||
As a result, the VM is now more likely to actually finish large
|
||||
anon targets than before.
|
||||
|
||||
Change the code such that only one SWAP_CLUSTER_MAX-sized nudge toward the
|
||||
larger LRU lists is made before bailing out on a met reclaim goal.
|
||||
|
||||
This fixes the extreme overreclaim problem.
|
||||
|
||||
Fairness is more subtle and harder to evaluate. No obvious misbehavior
|
||||
was observed on the test workload, in any case. Conceptually, fairness
|
||||
should primarily be a cumulative effect from regular, lower priority
|
||||
scans. Once the VM is in trouble and needs to escalate scan targets to
|
||||
make forward progress, fairness needs to take a backseat. This is also
|
||||
acknowledged by the myriad exceptions in get_scan_count(). This patch
|
||||
makes fairness decrease gradually, as it keeps fairness work static over
|
||||
increasing priority levels with growing scan targets. This should make
|
||||
more sense - although we may have to re-visit the exact values.

Subject: [PATCH] ZEN: Input: evdev - use call_rcu when detaching client
|
||||
|
||||
Significant time was spent on synchronize_rcu in evdev_detach_client
|
||||
when applications closed evdev devices. Switching VT away from a
|
||||
graphical environment commonly leads to mass input device closures,
|
||||
which could lead to noticable delays on systems with many input devices.
|
||||
|
||||
Replace synchronize_rcu with call_rcu, deferring reclaim of the evdev
|
||||
client struct till after the RCU grace period instead of blocking the
|
||||
calling application.
|
||||
|
||||
While this does not solve all slow evdev fd closures, it takes care of a
|
||||
good portion of them, including this simple test:
|
||||
|
||||
#include <fcntl.h>
|
||||
#include <unistd.h>
|
||||
|
||||
int main(int argc, char *argv[])
|
||||
{
|
||||
int idx, fd;
|
||||
const char *path = "/dev/input/event0";
|
||||
for (idx = 0; idx < 1000; idx++) {
|
||||
if ((fd = open(path, O_RDWR)) == -1) {
|
||||
return -1;
|
||||
}
|
||||
close(fd);
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
Time to completion of above test when run locally:
|
||||
|
||||
Before: 0m27.111s
|
||||
After: 0m0.018s

Subject: [PATCH] ZEN: mm: Lower the non-hugetlbpage pageblock size to reduce
|
||||
scheduling delays
|
||||
|
||||
The page allocator processes free pages in groups of pageblocks, where
|
||||
the size of a pageblock is typically quite large (1024 pages without
|
||||
hugetlbpage support). Pageblocks are processed atomically with the zone
|
||||
lock held, which can cause severe scheduling delays on both the CPU
|
||||
going through the pageblock and any other CPUs waiting to acquire the
|
||||
zone lock. A frequent offender is move_freepages_block(), which is used
|
||||
by rmqueue() for page allocation.
|
||||
|
||||
As it turns out, there's no requirement for pageblocks to be so large,
|
||||
so the pageblock order can simply be reduced to ease the scheduling
|
||||
delays and zone lock contention. PAGE_ALLOC_COSTLY_ORDER is used as a
|
||||
reasonable setting to ensure non-costly page allocation requests can
|
||||
still be serviced without always needing to free up more than one
|
||||
pageblock's worth of pages at a time.
|
||||
|
||||
This has a noticeable effect on overall system latency when memory
|
||||
pressure is elevated. The various mm functions which operate on
|
||||
pageblocks no longer appear in the preemptoff tracer, where previously
|
||||
they would spend up to 100 ms on a mobile arm64 CPU processing a

Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
|
||||
|
||||
There is noticeable scheduling latency and heavy zone lock contention
|
||||
stemming from rmqueue_bulk's single hold of the zone lock while doing
|
||||
its work, as seen with the preemptoff tracer. There's no actual need for
|
||||
rmqueue_bulk() to hold the zone lock the entire time; it only does so
|
||||
for supposed efficiency. As such, we can relax the zone lock and even
|
||||
reschedule when IRQs are enabled in order to keep the scheduling delays
|
||||
and zone lock contention at bay. Forward progress is still guaranteed,
|
||||
as the zone lock can only be relaxed after page removal.
|
||||
|
||||
With this change, rmqueue_bulk() no longer appears as a serious offender
|
||||
in the preemptoff tracer, and system latency is noticeably improved.

Subject: [PATCH] mm: vmscan: fix extreme overreclaim and swap floods
|
||||
|
||||
During proactive reclaim, we sometimes observe severe overreclaim, with
|
||||
several thousand times more pages reclaimed than requested.
|
||||
|
||||
This trace was obtained from shrink_lruvec() during such an instance:
|
||||
|
||||
prio:0 anon_cost:1141521 file_cost:7767
|
||||
nr_reclaimed:4387406 nr_to_reclaim:1047 (or_factor:4190)
|
||||
nr=[7161123 345 578 1111]
|
||||
|
||||
While he reclaimer requested 4M, vmscan reclaimed close to 16G, most of it
|
||||
by swapping. These requests take over a minute, during which the write()
|
||||
to memory.reclaim is unkillably stuck inside the kernel.
|
||||
|
||||
Digging into the source, this is caused by the proportional reclaim
|
||||
bailout logic. This code tries to resolve a fundamental conflict: to
|
||||
reclaim roughly what was requested, while also aging all LRUs fairly and
|
||||
in accordance to their size, swappiness, refault rates etc. The way it
|
||||
attempts fairness is that once the reclaim goal has been reached, it stops
|
||||
scanning the LRUs with the smaller remaining scan targets, and adjusts the
|
||||
remainder of the bigger LRUs according to how much of the smaller LRUs was
|
||||
scanned. It then finishes scanning that remainder regardless of the
|
||||
reclaim goal.
|
||||
|
||||
This works fine if priority levels are low and the LRU lists are
|
||||
comparable in size. However, in this instance, the cgroup that is
|
||||
targeted by proactive reclaim has almost no files left - they've already
|
||||
been squeezed out by proactive reclaim earlier - and the remaining anon
|
||||
pages are hot. Anon rotations cause the priority level to drop to 0,
|
||||
which results in reclaim targeting all of anon (a lot) and all of file
|
||||
(almost nothing). By the time reclaim decides to bail, it has scanned
|
||||
most or all of the file target, and therefor must also scan most or all of
|
||||
the enormous anon target. This target is thousands of times larger than
|
||||
the reclaim goal, thus causing the overreclaim.
|
||||
|
||||
The bailout code hasn't changed in years, why is this failing now? The
|
||||
most likely explanations are two other recent changes in anon reclaim:
|
||||
|
||||
1. Before the series starting with commit 5df741963d52 ("mm: fix LRU
|
||||
balancing effect of new transparent huge pages"), the VM was
|
||||
overall relatively reluctant to swap at all, even if swap was
|
||||
configured. This means the LRU balancing code didn't come into play
|
||||
as often as it does now, and mostly in high pressure situations
|
||||
where pronounced swap activity wouldn't be as surprising.
|
||||
|
||||
2. For historic reasons, shrink_lruvec() loops on the scan targets of
|
||||
all LRU lists except the active anon one, meaning it would bail if
|
||||
the only remaining pages to scan were active anon - even if there
|
||||
were a lot of them.
|
||||
|
||||
Before the series starting with commit ccc5dc67340c ("mm/vmscan:
|
||||
make active/inactive ratio as 1:1 for anon lru"), most anon pages
|
||||
would live on the active LRU; the inactive one would contain only a
|
||||
handful of preselected reclaim candidates. After the series, anon
|
||||
gets aged similarly to file, and the inactive list is the default
|
||||
for new anon pages as well, making it often the much bigger list.
|
||||
|
||||
As a result, the VM is now more likely to actually finish large
|
||||
anon targets than before.
|
||||
|
||||
Change the code such that only one SWAP_CLUSTER_MAX-sized nudge toward the
|
||||
larger LRU lists is made before bailing out on a met reclaim goal.
|
||||
|
||||
This fixes the extreme overreclaim problem.
|
||||
|
||||
Fairness is more subtle and harder to evaluate. No obvious misbehavior
|
||||
was observed on the test workload, in any case. Conceptually, fairness
|
||||
should primarily be a cumulative effect from regular, lower priority
|
||||
scans. Once the VM is in trouble and needs to escalate scan targets to
|
||||
make forward progress, fairness needs to take a backseat. This is also
|
||||
acknowledged by the myriad exceptions in get_scan_count(). This patch
|
||||
makes fairness decrease gradually, as it keeps fairness work static over
|
||||
increasing priority levels with growing scan targets. This should make
|
||||
more sense - although we may have to re-visit the exact values.

==================================================================
|
||||
|
||||
The task hangs because of a deadlock that occurs when lock_sock() is
|
||||
called in rfcomm_sk_state_change(). One such call stack is:
|
||||
|
||||
rfcomm_sock_shutdown():
|
||||
lock_sock();
|
||||
__rfcomm_sock_close():
|
||||
rfcomm_dlc_close():
|
||||
__rfcomm_dlc_close():
|
||||
rfcomm_dlc_lock();
|
||||
rfcomm_sk_state_change():
|
||||
lock_sock();
|
||||
|
||||
lock_sock() has to be called when the sk state is changed because the
|
||||
lock is not always held when rfcomm_sk_state_change() is
|
||||
called. However, besides the recursive deadlock, there is also an
|
||||
issue of a lock hierarchy inversion between rfcomm_dlc_lock() and
|
||||
lock_sock() if the socket is locked in rfcomm_sk_state_change().
|
||||
|
||||
To avoid these issues, we can instead schedule the sk state change in
|
||||
the global workqueue. This is already the implicit assumption about
|
||||
how sk state changes happen. For example, in rfcomm_sock_shutdown(),
|
||||
the call to __rfcomm_sock_close() is followed by
|
||||
bt_sock_wait_state().
|
||||
|
||||
Additionally, the call to rfcomm_sock_kill() inside
|
||||
rfcomm_sk_state_change() should be removed. The socket shouldn't be
|
||||
killed here because only rfcomm_sock_release() calls sock_orphan(),
|
||||
which it already follows up with a call to rfcomm_sock_kill().
|
||||

||||

Subject: [PATCH] intel_idle: tweak cpuidle cstates
|
||||
|
||||
Increase target_residency in cpuidle cstate
|
||||
|
||||
Tune intel_idle to be a bit less agressive;
|
||||
Clear linux is cleaner in hygiene (wakupes) than the average linux,
|
||||
so we can afford changing these in a way that increases
|
||||
performance while keeping power efficiency

Subject: [PATCH] initialize ata before graphics
|
||||
|
||||
ATA init is the long pole in the boot process, and its asynchronous.
|
||||
move the graphics init after it so that ata and graphics initialize
|
||||
in parallel

|

When the destination CPU is an SMT sibling and idle, it can only help the

busiest group if all of its other SMT siblings are also idle. Otherwise,

there is not increase in throughput.
|
||||

It does not matter whether the busiest group has SMT siblings. Simply

check if there are any tasks running on the local group before proceeding.

Subject: [PATCH 09/17] zen: Use [defer+madvise] as default khugepaged defrag
|
||||
strategy
|
||||
|
||||
For some reason, the default strategy to respond to THP fault fallbacks
|
||||
is still just madvise, meaning stall if the program wants transparent
|
||||
hugepages, but don't trigger a background reclaim / compaction if THP
|
||||
begins to fail allocations. This creates a snowball affect where we
|
||||
still use the THP code paths, but we almost always fail once a system
|
||||
has been active and busy for a while.
|
||||
|
||||
The option "defer" was created for interactive systems where THP can
|
||||
still improve performance. If we have to fallback to a regular page due
|
||||
to an allocation failure or anything else, we will trigger a background
|
||||
reclaim and compaction so future THP attempts succeed and previous
|
||||
attempts eventually have their smaller pages combined without stalling
|
||||
running applications.
|
||||
|
||||
We still want madvise to stall applications that explicitely want THP,
|
||||
so defer+madvise _does_ make a ton of sense. Make it the default for
|
||||
interactive systems, especially if the kernel maintainer left
|
||||
transparent hugepages on "always".
|
||||
|
||||

The value is still pretty low, and AMD64-ABI and ELF extended numbering

supports that, so we should be fine on modern x86 systems.

This fixes crashes in some applications using more than 65535 vmas (also

Subject: [PATCH 17/17] ZEN: intel-pstate: Implement "enable" parameter
|
||||
|
||||
If intel-pstate is compiled into the kernel, it will preempt the loading
|
||||
of acpi-cpufreq so you can take advantage of hardware p-states without
|
||||
any friction.
|
||||
|
||||
However, intel-pstate is not completely superior to cpufreq's ondemand
|
||||
for one reason. There's no concept of an up_threshold property.
|
||||
|
||||
In ondemand, up_threshold essentially reduces the maximum utilization to
|
||||
compare against, allowing you to hit max frequencies and turbo boost
|
||||
from a much lower core utilization.
|
||||
|
||||
With intel-pstate, you have the concept of minimum and maximum
|
||||
performance, but no tunable that lets you define, maximum frequency
|
||||
means 50% core utilization. For just this oversight, there's reasons
|
||||
you may want ondemand.
|
||||
|
||||
Lets support setting "enable" in kernel boot parameters. This lets
|
||||
kernel maintainers include "intel_pstate=disable" statically in the
|
||||
static boot parameters, but let users of the kernel override this
|
||||
selection.

Subject: [PATCH] ZEN: Input: evdev - use call_rcu when detaching client
|
||||
|
||||
Significant time was spent on synchronize_rcu in evdev_detach_client
|
||||
when applications closed evdev devices. Switching VT away from a
|
||||
graphical environment commonly leads to mass input device closures,
|
||||
which could lead to noticable delays on systems with many input devices.
|
||||
|
||||
Replace synchronize_rcu with call_rcu, deferring reclaim of the evdev
|
||||
client struct till after the RCU grace period instead of blocking the
|
||||
calling application.
|
||||
|
||||
While this does not solve all slow evdev fd closures, it takes care of a
|
||||
good portion of them, including this simple test:
|
||||
|
||||
#include <fcntl.h>
|
||||
#include <unistd.h>
|
||||
|
||||
int main(int argc, char *argv[])
|
||||
{
|
||||
int idx, fd;
|
||||
const char *path = "/dev/input/event0";
|
||||
for (idx = 0; idx < 1000; idx++) {
|
||||
if ((fd = open(path, O_RDWR)) == -1) {
|
||||
return -1;
|
||||
}
|
||||
close(fd);
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
Time to completion of above test when run locally:

Subject: [PATCH] ZEN: mm: Lower the non-hugetlbpage pageblock size to reduce
|
||||
scheduling delays
|
||||
|
||||
The page allocator processes free pages in groups of pageblocks, where
|
||||
the size of a pageblock is typically quite large (1024 pages without
|
||||
hugetlbpage support). Pageblocks are processed atomically with the zone
|
||||
lock held, which can cause severe scheduling delays on both the CPU
|
||||
going through the pageblock and any other CPUs waiting to acquire the
|
||||
zone lock. A frequent offender is move_freepages_block(), which is used
|
||||
by rmqueue() for page allocation.
|
||||
|
||||
As it turns out, there's no requirement for pageblocks to be so large,
|
||||
so the pageblock order can simply be reduced to ease the scheduling
|
||||
delays and zone lock contention. PAGE_ALLOC_COSTLY_ORDER is used as a
|
||||
reasonable setting to ensure non-costly page allocation requests can
|
||||
still be serviced without always needing to free up more than one
|
||||
pageblock's worth of pages at a time.
|
||||
|
||||
This has a noticeable effect on overall system latency when memory
|
||||
pressure is elevated. The various mm functions which operate on
|
||||
pageblocks no longer appear in the preemptoff tracer, where previously
|
||||
they would spend up to 100 ms on a mobile arm64 CPU processing a
|
||||
pageblock with preemption disabled and the zone lock held.

Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
|
||||
|
||||
There is noticeable scheduling latency and heavy zone lock contention
|
||||
stemming from rmqueue_bulk's single hold of the zone lock while doing
|
||||
its work, as seen with the preemptoff tracer. There's no actual need for
|
||||
rmqueue_bulk() to hold the zone lock the entire time; it only does so
|
||||
for supposed efficiency. As such, we can relax the zone lock and even
|
||||
reschedule when IRQs are enabled in order to keep the scheduling delays
|
||||
and zone lock contention at bay. Forward progress is still guaranteed,
|
||||
as the zone lock can only be relaxed after page removal.
|
||||
|
||||
With this change, rmqueue_bulk() no longer appears as a serious offender
|
||||
in the preemptoff tracer, and system latency is noticeably improved.

|
||||
- * waking task. find_energy_efficient_cpu() looks for the CPU with maximum
|
||||
- * spare capacity in each performance domain and uses it as a potential
|
||||
- * candidate to execute the task. Then, it uses the Energy Model to figure
|
||||
- * out which of the CPU candidates is the most energy-efficient.
|
||||
- *
|
||||
- * The rationale for this heuristic is as follows. In a performance domain,
|
||||
- * all the most energy efficient CPU candidates (according to the Energy
|
||||
- * Model) are those for which we'll request a low frequency. When there are
|
||||
- * several CPUs for which the frequency request will be the same, we don't
|
||||
- * have enough data to break the tie between them, because the Energy Model
|
||||
- * only includes active power costs. With this model, if we assume that
|
||||
- * frequency requests follow utilization (e.g. using schedutil), the CPU with
|
||||
- * the maximum spare capacity in a performance domain is guaranteed to be among
|
||||
- * the best candidates of the performance domain.
|
||||
- *
|
||||
- * In practice, it could be preferable from an energy standpoint to pack
|
||||
- * small tasks on a CPU in order to let other CPUs go in deeper idle states,
|
||||
- * but that could also hurt our chances to go cluster idle, and we have no
|
||||
- * ways to tell with the current Energy Model if this is actually a good
|
||||
- * idea or not. So, find_energy_efficient_cpu() basically favors
|
||||
- * cluster-packing, and spreading inside a cluster. That should at least be
|
||||
- * a good thing for latency, and this is consistent with the idea that most
|
||||
- * of the energy savings of EAS come from the asymmetry of the system, and
|
||||
- * not so much from breaking the tie between identical CPUs. That's also the
|
||||
- * reason why EAS is enabled in the topology code only for systems where
|
||||
- * SD_ASYM_CPUCAPACITY is set.
|
||||
- *
|
||||
- * NOTE: Forkees are not accepted in the energy-aware wake-up path because
|
||||
- * they don't have any useful utilization data yet and it's not possible to
|
||||
- * forecast their impact on energy consumption. Consequently, they will be
|
||||
- * placed by find_idlest_cpu() on the least loaded CPU, which might turn out
|
||||
- * to be energy-inefficient in some use-cases. The alternative would be to
|
||||
- * bias new tasks towards specific types of CPUs first, or to try to infer
|
||||
- * their util_avg from the parent task, but those heuristics could hurt
|
||||
- * other use-cases too. So, until someone finds a better way to solve this,
|
||||
- * let's keep things simple by re-using the existing slow path.

Subject: [PATCH] pci: Enable overrides for missing ACS capabilities
|
||||
|
||||
This an updated version of Alex Williamson's patch from:
|
||||
https://lkml.org/lkml/2013/5/30/513
|
||||
|
||||
Original commit message follows:
|
||||
|
||||
PCIe ACS (Access Control Services) is the PCIe 2.0+ feature that
|
||||
allows us to control whether transactions are allowed to be redirected
|
||||
in various subnodes of a PCIe topology. For instance, if two
|
||||
endpoints are below a root port or downsteam switch port, the
|
||||
downstream port may optionally redirect transactions between the
|
||||
devices, bypassing upstream devices. The same can happen internally
|
||||
on multifunction devices. The transaction may never be visible to the
|
||||
upstream devices.
|
||||
|
||||
One upstream device that we particularly care about is the IOMMU. If
|
||||
a redirection occurs in the topology below the IOMMU, then the IOMMU
|
||||
cannot provide isolation between devices. This is why the PCIe spec
|
||||
encourages topologies to include ACS support. Without it, we have to
|
||||
assume peer-to-peer DMA within a hierarchy can bypass IOMMU isolation.
|
||||
|
||||
Unfortunately, far too many topologies do not support ACS to make this
|
||||
a steadfast requirement. Even the latest chipsets from Intel are only
|
||||
sporadically supporting ACS. We have trouble getting interconnect
|
||||
vendors to include the PCIe spec required PCIe capability, let alone
|
||||
suggested features.
|
||||
|
||||
Therefore, we need to add some flexibility. The pcie_acs_override=
|
||||
boot option lets users opt-in specific devices or sets of devices to
|
||||
assume ACS support. The "downstream" option assumes full ACS support
|
||||
on root ports and downstream switch ports. The "multifunction"
|
||||
option assumes the subset of ACS features available on multifunction
|
||||
endpoints and upstream switch ports are supported. The "id:nnnn:nnnn"
|
||||
option enables ACS support on devices matching the provided vendor
|
||||
and device IDs, allowing more strategic ACS overrides. These options
|
||||
may be combined in any order. A maximum of 16 id specific overrides
|
||||
are available. It's suggested to use the most limited set of options
|
||||
necessary to avoid completely disabling ACS across the topology.
|
||||
Note to hardware vendors, we have facilities to permanently quirk
|
||||
specific devices which enforce isolation but not provide an ACS
|
||||
capability. Please contact me to have your devices added and save
|
||||
your customers the hassle of this boot option.

Add an option to wait on multiple futexes using the old interface, that
|
||||
uses opcode 31 through futex() syscall. Do that by just translation the
|
||||
old interface to use the new code. This allows old and stable versions
|
||||
of Proton to still use fsync in new kernel releases.

there were severe stability issues when both drivers (hid-generic and

hid-magicmouse) were loaded for this device.

Subject: Revert "cpufreq: Avoid configuring old governors as default with intel_pstate"
|
||||
|
||||
This is an undesirable behavior for us since our aggressive ondemand performs
|
||||
better than schedutil for gaming when using intel_pstate in passive mode.
|
||||
Also it interferes with the option to select the desired default governor we have.

Subject: [PATCH] intel_idle: tweak cpuidle cstates
|
||||
|
||||
Increase target_residency in cpuidle cstate
|

|

Tune intel_idle to be a bit less agressive;
|
||||
Clear linux is cleaner in hygiene (wakupes) than the average linux,
|

so we can afford changing these in a way that increases
|

performance while keeping power efficiency

Subject: [PATCH 3/9] sched/fair: Simplify asym_packing logic for SMT sched
|
||||
groups
|
||||
|
||||
When the destination CPU is an SMT sibling and idle, it can only help the
|
||||
busiest group if all of its other SMT siblings are also idle. Otherwise,
|
||||
there is not increase in throughput.
|
||||
|
||||
It does not matter whether the busiest group has SMT siblings. Simply
|
||||
check if there are any tasks running on the local group before proceeding.

Subject: [PATCH 4/9] sched/fair: Let lower-priority CPUs do active balancing
|
||||
|
||||
When more than one SMT siblings of a physical core are busy, an idle CPU
|
||||
of lower priority can help.
|
||||
|
||||
Indicate that the low priority CPU can do active balancing from the high-
|
||||
priority CPU only if they belong to separate cores.

Subject: [PATCH 09/17] zen: Use [defer+madvise] as default khugepaged defrag
|
||||
strategy
|
||||
|
||||
For some reason, the default strategy to respond to THP fault fallbacks
|
||||
is still just madvise, meaning stall if the program wants transparent
|
||||
hugepages, but don't trigger a background reclaim / compaction if THP
|
||||
begins to fail allocations. This creates a snowball affect where we
|
||||
still use the THP code paths, but we almost always fail once a system
|
||||
has been active and busy for a while.
|
||||
|
||||
The option "defer" was created for interactive systems where THP can
|
||||
still improve performance. If we have to fallback to a regular page due
|
||||
to an allocation failure or anything else, we will trigger a background
|
||||
reclaim and compaction so future THP attempts succeed and previous
|
||||
attempts eventually have their smaller pages combined without stalling
|
||||
running applications.
|
||||
|
||||
We still want madvise to stall applications that explicitely want THP,
|
||||
so defer+madvise _does_ make a ton of sense. Make it the default for
|
||||
interactive systems, especially if the kernel maintainer left
|
||||
transparent hugepages on "always".
|
||||
|
||||

The value is still pretty low, and AMD64-ABI and ELF extended numbering

supports that, so we should be fine on modern x86 systems.
|

|

This fixes crashes in some applications using more than 65535 vmas (also

Subject: [PATCH 17/17] ZEN: intel-pstate: Implement "enable" parameter
|
||||
|
||||
If intel-pstate is compiled into the kernel, it will preempt the loading
|
||||
of acpi-cpufreq so you can take advantage of hardware p-states without
|
||||
any friction.
|
||||
|
||||
However, intel-pstate is not completely superior to cpufreq's ondemand
|
||||
for one reason. There's no concept of an up_threshold property.
|
||||
|
||||
In ondemand, up_threshold essentially reduces the maximum utilization to
|
||||
compare against, allowing you to hit max frequencies and turbo boost
|
||||
from a much lower core utilization.
|
||||
|
||||
With intel-pstate, you have the concept of minimum and maximum
|
||||
performance, but no tunable that lets you define, maximum frequency
|
||||
means 50% core utilization. For just this oversight, there's reasons
|
||||
you may want ondemand.
|
||||
|
||||
Lets support setting "enable" in kernel boot parameters. This lets
|
||||
kernel maintainers include "intel_pstate=disable" statically in the
|
||||
static boot parameters, but let users of the kernel override this
|
||||
selection.

Subject: [PATCH] ZEN: Input: evdev - use call_rcu when detaching client
|
||||
|
||||
Significant time was spent on synchronize_rcu in evdev_detach_client
|
||||
when applications closed evdev devices. Switching VT away from a
|
||||
graphical environment commonly leads to mass input device closures,
|
||||
which could lead to noticable delays on systems with many input devices.
|
||||
|
||||
Replace synchronize_rcu with call_rcu, deferring reclaim of the evdev
|
||||
client struct till after the RCU grace period instead of blocking the
|
||||
calling application.
|
||||
|
||||
While this does not solve all slow evdev fd closures, it takes care of a
|
||||
good portion of them, including this simple test:
|
||||
|
||||
#include <fcntl.h>
|
||||
#include <unistd.h>
|
||||
|
||||
int main(int argc, char *argv[])
|
||||
{
|
||||
int idx, fd;
|
||||
const char *path = "/dev/input/event0";
|
||||
for (idx = 0; idx < 1000; idx++) {

if ((fd = open(path, O_RDWR)) == -1) {

return -1;

}

||||
close(fd);
|
||||
}
|

return 0;

||||
}
|

Subject: [PATCH] ZEN: mm: Lower the non-hugetlbpage pageblock size to reduce
|
||||
scheduling delays
|
||||
|
||||
The page allocator processes free pages in groups of pageblocks, where
|
||||
the size of a pageblock is typically quite large (1024 pages without
|
||||
hugetlbpage support). Pageblocks are processed atomically with the zone
|
||||
lock held, which can cause severe scheduling delays on both the CPU
|
||||
going through the pageblock and any other CPUs waiting to acquire the
|
||||
zone lock. A frequent offender is move_freepages_block(), which is used
|
||||
by rmqueue() for page allocation.
|
||||
|
||||
As it turns out, there's no requirement for pageblocks to be so large,
|
||||
so the pageblock order can simply be reduced to ease the scheduling
|
||||
delays and zone lock contention. PAGE_ALLOC_COSTLY_ORDER is used as a
|
||||
reasonable setting to ensure non-costly page allocation requests can
|
||||
still be serviced without always needing to free up more than one
|
||||
pageblock's worth of pages at a time.
|
||||
|
||||
This has a noticeable effect on overall system latency when memory
|
||||
pressure is elevated. The various mm functions which operate on
|
||||
pageblocks no longer appear in the preemptoff tracer, where previously
|
||||
they would spend up to 100 ms on a mobile arm64 CPU processing a
|
||||
pageblock with preemption disabled and the zone lock held.

Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
|
||||
|
||||
There is noticeable scheduling latency and heavy zone lock contention
|
||||
stemming from rmqueue_bulk's single hold of the zone lock while doing
|
||||
its work, as seen with the preemptoff tracer. There's no actual need for
|
||||
rmqueue_bulk() to hold the zone lock the entire time; it only does so
|
||||
for supposed efficiency. As such, we can relax the zone lock and even
|
||||
reschedule when IRQs are enabled in order to keep the scheduling delays
|
||||
and zone lock contention at bay. Forward progress is still guaranteed,
|
||||
as the zone lock can only be relaxed after page removal.
|
||||
|
||||
With this change, rmqueue_bulk() no longer appears as a serious offender
|
||||
in the preemptoff tracer, and system latency is noticeably improved.

- * spare capacity in each performance domain and uses it as a potential
|
||||
- * candidate to execute the task. Then, it uses the Energy Model to figure
|
||||
- * out which of the CPU candidates is the most energy-efficient.
|
||||
- *
|
||||
- * The rationale for this heuristic is as follows. In a performance domain,
|
||||
- * all the most energy efficient CPU candidates (according to the Energy
|
||||
- * Model) are those for which we'll request a low frequency. When there are
|
||||
- * several CPUs for which the frequency request will be the same, we don't
|
||||
- * have enough data to break the tie between them, because the Energy Model
|
||||
- * only includes active power costs. With this model, if we assume that
|
||||
- * frequency requests follow utilization (e.g. using schedutil), the CPU with
|
||||
- * the maximum spare capacity in a performance domain is guaranteed to be among
|
||||
- * the best candidates of the performance domain.
|
||||
- *
|
||||
- * In practice, it could be preferable from an energy standpoint to pack
|
||||
- * small tasks on a CPU in order to let other CPUs go in deeper idle states,
|
||||
- * but that could also hurt our chances to go cluster idle, and we have no
|
||||
- * ways to tell with the current Energy Model if this is actually a good
|
||||
- * idea or not. So, find_energy_efficient_cpu() basically favors
|
||||
- * cluster-packing, and spreading inside a cluster. That should at least be
|
||||
- * a good thing for latency, and this is consistent with the idea that most
|
||||
- * of the energy savings of EAS come from the asymmetry of the system, and
|
||||
- * not so much from breaking the tie between identical CPUs. That's also the
|
||||
- * reason why EAS is enabled in the topology code only for systems where
|
||||
- * SD_ASYM_CPUCAPACITY is set.
|
||||
- *
|
||||
- * NOTE: Forkees are not accepted in the energy-aware wake-up path because
|
||||
- * they don't have any useful utilization data yet and it's not possible to
|
||||
- * forecast their impact on energy consumption. Consequently, they will be
|
||||
- * placed by find_idlest_cpu() on the least loaded CPU, which might turn out
|
||||
- * to be energy-inefficient in some use-cases. The alternative would be to
|
||||
- * bias new tasks towards specific types of CPUs first, or to try to infer
|
||||
- * their util_avg from the parent task, but those heuristics could hurt
|
||||
- * other use-cases too. So, until someone finds a better way to solve this,

Subject: [PATCH] pci: Enable overrides for missing ACS capabilities
|
||||
|
||||
This an updated version of Alex Williamson's patch from:
|
||||
https://lkml.org/lkml/2013/5/30/513
|
||||
|
||||
Original commit message follows:
|
||||
|
||||
PCIe ACS (Access Control Services) is the PCIe 2.0+ feature that
|
||||
allows us to control whether transactions are allowed to be redirected
|
||||
in various subnodes of a PCIe topology. For instance, if two
|
||||
endpoints are below a root port or downsteam switch port, the
|
||||
downstream port may optionally redirect transactions between the
|
||||
devices, bypassing upstream devices. The same can happen internally
|
||||
on multifunction devices. The transaction may never be visible to the
|
||||
upstream devices.
|
||||
|
||||
One upstream device that we particularly care about is the IOMMU. If
|
||||
a redirection occurs in the topology below the IOMMU, then the IOMMU
|
||||
cannot provide isolation between devices. This is why the PCIe spec
|
||||
encourages topologies to include ACS support. Without it, we have to
|
||||
assume peer-to-peer DMA within a hierarchy can bypass IOMMU isolation.
|
||||
|
||||
Unfortunately, far too many topologies do not support ACS to make this
|
||||
a steadfast requirement. Even the latest chipsets from Intel are only
|
||||
sporadically supporting ACS. We have trouble getting interconnect
|
||||
vendors to include the PCIe spec required PCIe capability, let alone
|
||||
suggested features.
|
||||
|
||||
Therefore, we need to add some flexibility. The pcie_acs_override=
|
||||
boot option lets users opt-in specific devices or sets of devices to
|
||||
assume ACS support. The "downstream" option assumes full ACS support
|
||||
on root ports and downstream switch ports. The "multifunction"
|
||||
option assumes the subset of ACS features available on multifunction
|
||||
endpoints and upstream switch ports are supported. The "id:nnnn:nnnn"
|
||||
option enables ACS support on devices matching the provided vendor
|
||||
and device IDs, allowing more strategic ACS overrides. These options
|
||||
may be combined in any order. A maximum of 16 id specific overrides
|
||||
are available. It's suggested to use the most limited set of options
|
||||
necessary to avoid completely disabling ACS across the topology.
|
||||
Note to hardware vendors, we have facilities to permanently quirk
|
||||
specific devices which enforce isolation but not provide an ACS
|
||||
capability. Please contact me to have your devices added and save
|
||||
your customers the hassle of this boot option.

Add an option to wait on multiple futexes using the old interface, that
|
||||
uses opcode 31 through futex() syscall. Do that by just translation the
|
||||
old interface to use the new code. This allows old and stable versions
|
||||
of Proton to still use fsync in new kernel releases.

The Apple Magic Trackpad 2 is handled by the magicmouse driver. And
|
||||
there were severe stability issues when both drivers (hid-generic and
|
||||
hid-magicmouse) were loaded for this device.

Subject: Revert "cpufreq: Avoid configuring old governors as default with intel_pstate"
|
||||
|
||||
This is an undesirable behavior for us since our aggressive ondemand performs
|
||||
better than schedutil for gaming when using intel_pstate in passive mode.
|
||||
Also it interferes with the option to select the desired default governor we have.
