On some platforms, including Sky Lake and Kaby Lake, the PSIV (Protocol
Speed ID Value) indices are shared between Protocol Speed ID DWORD' in
the extended capabilities registers for both USB2 (Full Speed) and USB3
(Super Speed).
An example can be found below:
XhcCheckUsbPortSpeedUsedPsic: checking for USB2 ext caps
XhciPsivGetPsid: found 3 PSID entries
XhciPsivGetPsid: looking for port speed 1
XhciPsivGetPsid: PSIV 1 PSIE 2 PLT 0 PSIM 12
XhciPsivGetPsid: PSIV 2 PSIE 1 PLT 0 PSIM 1500
XhciPsivGetPsid: PSIV 3 PSIE 2 PLT 0 PSIM 480
XhcCheckUsbPortSpeedUsedPsic: checking for USB3 ext caps
XhciPsivGetPsid: found 3 PSID entries
XhciPsivGetPsid: looking for port speed 1
XhciPsivGetPsid: PSIV 1 PSIE 3 PLT 0 PSIM 5
XhciPsivGetPsid: PSIV 2 PSIE 3 PLT 0 PSIM 10
XhciPsivGetPsid: PSIV 34 PSIE 2 PLT 0 PSIM 1248
The result is edk2 detecting USB2 devices as USB3 devices, which
consequently causes enumeration to fail.
To avoid incorrect detection, check the Compatible Port Offset to find
the starting Port of Root Hubs that support the protocol.

PSID matching relies on comparing the PSIV against the PortSpeed
value. This patch stops edk2 from checking for a PSIV of 0, as it
is not valid; this reduces the number of register access by
approximately 6 per second.

With the pending commit of UsbNetworkPkg, it will become common for
UsbBulkTransfer calls to timeout, given that the drivers are called from
MnpSystemPoll every MNP_SYS_POLL_INTERVAL milliseconds: the drivers
check for network packets by calling UsbBulkTransfer with a timeout of
1ms.
Avoid console spam by moving DEBUG messages that occur each time a bulk
transfer request times out from DEBUG_ERROR to DEBUG_VERBOSE, for both
EHCI and XHCI drivers.

If a device which support both features SR-IOV/ARI has multi
functions, which maybe support 8-255. After enable ARI forwarding in
the root port and ARI Capable Hierarchy in the SR-IOV PF0.
The device will support and expose multi functions(0-255) with ARI ID routing.
In next device loop in below for() code, actually it still be in the
same SR-IOV device, and just some PF which is over 8 or higher
one(n*8), PciAllocateBusNumber() will allocate bus
number(ReservedBusNum - TempReservedBusNum)) for this PF. if reset
TempReservedBusNum as 0 in this case,it will allocate wrong bus number
for this PF because TempReservedBusNum should be total previous PF's
reserved bus numbers.
code:
for (Device = 0; Device <= PCI_MAX_DEVICE; Device++) {
TempReservedBusNum = 0;
for (Func = 0; Func <= PCI_MAX_FUNC; Func++) {
//
// Check to see whether a pci device is present
//

...
Status = PciAllocateBusNumber (PciDevice, *SubBusNumber,
(UINT8)(PciDevice->ReservedBusNum - TempReservedBusNum), SubBusNumber);
The solution is add a new flag IsAriEnabled to help handle this case.
if ARI is enabled, then TempReservedBusNum will not be reset again
during all functions(1-255) scan with checking flag IsAriEnabled.

Below code will calculate the reserved bus number for the each PF.
Based on the VF routing ID algorithm, PFRid and LastVF in below code
already sure that "All VFs and PFs must have distinct Routing IDs".
PF will be assigned Routing ID based on secBusNumber, ReservedBusNum
will add into SubBusNumber directly. So the SR-IOV device will be
assigned bus range as SecBusNumber ~ (SubBusNumber=(SecBusNumber +
ReservedBusNum)).
Thus "+1" in below code will cause extra 1 bus, and introduce a bus hole.
PFRid = EFI_PCI_RID (Bus, Device, Func);
LastVF = PFRid + FirstVFOffset + (PciIoDevice->InitialVFs - 1) * VFStride;
PciIoDevice->ReservedBusNum = (UINT16)(EFI_PCI_BUS_OF_RID (LastVF) -
Bus + 1);
In SR-IOV spec, there is a note in section 2.1.2:
Note: Bus Numbers are a constrained resource. Devices are strongly
encouraged to avoid leaving ?holes? in their Bus Number usage to avoid
wasting Bus Numbers
So the issue can be fixed with below code change.
PciIoDevice->ReservedBusNum = (UINT16)(EFI_PCI_BUS_OF_RID (LastVF) -
Bus);

Move the logic that stores starting PCI attributes and sets the
EFI_PCI_IO_ATTRIBUTE_DUAL_ADDRESS_CYCLE attribute to
DriverBindingStart() before the memory that backs the
DMA engine is allocated.
This ensures that the DMA-backing memory is not forcibly allocated
below 4G in system address map. Otherwise the allocation fails on
platforms that do not have any memory below the 4G mark and the drive
initialisation fails.
Leave the PCI device enabling attribute logic in NvmeControllerInit()
to ensure that the device is re-enabled on reset in case it was
disabled via PCI attributes.

Remove ASSERT() statements that are triggered if a platform provides
an override of PCI ROM attached to a PCI Controller. The PCI Platform
Protocol allows the platform to provide a PCI ROM image for a PCI
Controller. This works for PCI Controllers that do not have an attached
PCI ROM, but the platform is not allowed to replace the PCI ROM for a
PCI Controller that has its own PCI ROM. Removing these ASSERT()
statements enables this additional use case.

This change prevents lost characters on serial debug logs
