MdeModulePkg/XhciDxe: Add PCD for the delay of HCRST

2024-05-07T04:48:09+00:00

https://bugzilla.tianocore.org/show_bug.cgi?id=4727 Recently some of XHCI host controllers require to have extra 1ms delay before accessing any MMIO register during reset. PHY transition from P3 to P0 can take around 1.3ms and the xHCI reset can take around 1.5ms. Add PCD to control the delay, the default is 2 ms.

MdeModulePkg/XhciDxe: Reset endpoint while USB Transaction error

2024-05-07T02:26:46+00:00

https://bugzilla.tianocore.org/show_bug.cgi?id=4556 Based on XHCI spec 4.8.3, software should do the reset endpoint while USB Transaction occur. Add the error code for USB Transaction error since UEFI spec don't have the related definition.

MdeModulePkg/Xhci: Skip another size round up for TRB address

2024-03-22T04:47:04+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4560 Commit f36e1ec1f0a5fd3be84913e09181d7813444b620 had fixed the DXE_ASSERT caused by the TRB size round up from 16 to 64 for most cases. However, there is a remaining case that the TRB size is also rounded up during setting TR dequeue pointer that would trigger DXE_ASSERT. This patch sets the alignment flag to FALSE in XhcSetTrDequeuePointer to fix this issue as well.

MdeModulePkg/Bus: Fix XhciDxe Linker Issues

2023-12-06T23:52:13+00:00

The DXE & MM standalone variant of AcpiTimerLib defines a global named mPerformanceCounterFrequency. A global with an identical name is also present in MdeModulePkg/Bus/Pci/XhciDxe/Xhci.c Since XhciDxe has a dependency on TimerLib, this can cause link errors due to the same symbol being defined twice if the platform DSC chooses to use AcpiTimerLib as the TimerLib implementation for any given platform. To resolve this, I noted that some of the globals in Xhci.c are not used outside of the Xhci.c compilation unit: - mPerformanceCounterStartValue - mPerformanceCounterEndValue - mPerformanceCounterFrequency - mPerformanceCounterValuesCached I have changed the definition for all of these to static and added an Xhci prefix. Since they are not used outside of the Xhci.c compilation unit, there is no reason to have them exported as globals. Reviewed-by: Ray Ni Cc: Michael D Kinney Signed-off-by: Nate DeSimone

MdeModulePkg/Xhci: Skip size round up for TRB during address translation

2023-09-28T02:02:11+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4560 TRB Template is 16 bytes. When boundary checking is 64 bytes for xHCI device/host memory address, it may exceed xHCI host memory pool and cause unwanted DXE_ASSERT. Introduce a new input parameter to indicate whether to enforce 64byte size alignment and round up. For TRB case, should set it to FALSE to skip the size round up.

MdeModulePkg/XhciDxe: Use Performance Timer for XHCI Timeouts

2023-09-25T02:56:05+00:00

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2948 XhciDxe uses the timer functionality provided by the boot services table to detect timeout conditions. This breaks the driver's ExitBootServices call back, as CoreExitBootServices halts the timer before signaling the ExitBootServices event. If the host controller fails to halt in the call back, the timeout condition will never occur and the boot gets stuck in an indefinite spin loop. Use the free running timer provided by TimerLib to calculate timeouts, avoiding the potential hang. Cc: Hao A Wu Cc: Ray Ni Signed-off-by: Patrick Henz Reviewed-by: Hao A Wu
