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] soundwire: intel: Initialize clock stop timeout
|
||||
|
||||
The bus->clk_stop_timeout member is only initialized to a non-zero value
|
||||
during the codec driver probe. This can lead to corner cases where this
|
||||
value remains pegged at zero when the bus suspends, which results in an
|
||||
endless loop in sdw_bus_wait_for_clk_prep_deprep().
|
||||
|
||||
Corner cases include configurations with no codecs described in the
|
||||
firmware, or delays in probing codec drivers.
|
||||
|
||||
Initializing the default timeout to the smallest non-zero value avoid this
|
||||
problem and allows for the existing logic to be preserved: the
|
||||
bus->clk_stop_timeout is set as the maximum required by all codecs
|
||||
connected on the bus.

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".
|
||||

||||

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] 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.

Also it interferes with the option to select the desired default governor we have.

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().

||||
