2016-08-03MdeModulePkg/UsbMass: Not retry if usb bot transfer execution failFeng Tian
The retry mechanism will bring issue if the usb device is unplugged from XHCI HC but s/w is trying to access it through BlockIo. The current cmd will get device error return status, but the sequential cmds will be timeout. This behavior will cause system unresponsive for a long while and bring bad user experience. So we break the retry loop if found device error. Cc: Star Zeng <star.zeng@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Feng Tian <feng.tian@intel.com>

2016-07-25MdeModulePkg/UsbBus: reduce the port status polling before port resetFeng Tian
This change is used to remove the port status polling in port reset functions. Why it's needed is because: 1) The same polling on same port has taken place prior to this removed one. See UsbEnumeratePort()->GetPortStatus(). So this polling in UsbEnumerateNewDev()->ResetPort() is redundant. 2) EDKII Xhci driver hooks all GetPortStatus() operations. If we don't remove this one, XHCI driver's XhcPollPortStatusChange() may enter twice in reset process and wrongly think the device is unplugged.

2016-07-13MdeModulePkg/PciBusDxe: recognize hotplug-capable PCIe portsLaszlo Ersek
Section 7.8.2 of the PCI Express specification (r4.0 v0.3), entitled "PCI Express Capabilities Register (Offset 02h)", and section 7.8.9 "Slot Capabilities Register (Offset 14h)" of the same, describe the conditions when a PCIe port should be considered "supporting hotplug": - it should be a root complex port or a switch downstream port, and - it should have the "Slot Implemented" bit set in the Express Capabilities Register, and - it should have the "Hot-Plug Capable" bit set in the Slot Capabilities Register. The first two sub-conditions are already implemented in at least two open source projects I could find: - in SeaBIOS by Marcel Apfelbaum: "hw/pci: reserve IO and mem for pci express downstream ports with no devices attached" <https://code.coreboot.org/p/seabios/source/commit/3aa31d7d6375>, - in edk2 itself, in the implementation of the "PCI" UEFI Shell command: see the "PcieExplainTypeSlot" case label in function PciExplainPciExpress(), file "ShellPkg/Library/UefiShellDebug1CommandsLib/Pci.c". PciBusDxe recognizes such PCIe ports as bridges, but it doesn't realize they support hotplug. In turn PciBusDxe omits getting any resource padding information from the platform's EFI_PCI_HOT_PLUG_INIT_PROTOCOL for these bridges: GatherPpbInfo() [PciEnumeratorSupport.c] GetResourcePaddingPpb() [PciResourceSupport.c] GetResourcePaddingForHpb() [PciHotPlugSupport.c] IsPciHotPlugBus() [PciHotPlugSupport.c] // // returns FALSE // // // the following is not reached: // gPciHotPlugInit->GetResourcePadding() Implement a function called SupportsPcieHotplug() for identifying such ports, and call it from IsPciHotPlugBus() (after the call to IsSHPC()).

2016-05-05MdeModulePkg: ScsiDiskDxe: cope with broken "Supported VPD Pages" VPD pageLaszlo Ersek
The USB flash drive with Vendor ID 0x1516 (CompUSA) and Product ID 0x6221 returns a broken "Supported VPD Pages" VPD page. In particular, the PageLength field has the invalid value 0x0602 (decimal 1538). This prevents the loop from terminating that scans for the Block Limits VPD page code in ScsiDiskInquiryDevice(): for (Index = 0; Index < PageLength; Index++) { because the Index variable has type UINT8, and it wraps from 255 to 0, without ever reaching PageLength (1538), and because EFI_SCSI_PAGE_CODE_BLOCK_LIMITS_VPD does not occur at offsets 0 through 255. * The fix is not to change the type of Index to UINT16 or a wider type. Namely, section 7.8.14 Supported VPD Pages VPD page in the "SCSI Primary Commands - 4" (SPC-4) specification names the following requirement: The supported VPD page list shall contain a list of all VPD page codes (see 7.8) implemented by the logical unit in ascending order beginning with page code 00h. Since page codes are 8-bit unsigned quantities, it follows that the maximum size for the Supported VPD Pages VPD page is 0x100 bytes, in which every possible page code (0x00 through 0xFF) will be found, before the UINT8 offset wraps around. (EFI_SCSI_SUPPORTED_VPD_PAGES_VPD_PAGE.SupportedVpdPageList is correctly sized as well, in "MdePkg/Include/IndustryStandard/Scsi.h".) * Instead, add sanity checks that enforce the above requirement. If the device breaks the spec, simply fall back to the "Block Limits page absent" case.

2016-04-29MdeModulePkg/PciBusDxe: don't create bogus descriptor if no resources neededArd Biesheuvel
If the current PCI configuration requires no resources to be allocated at all (i.e., unpopulated bus), the PCI enumeration code creates a single ACPI_ADDRESS_SPACE_DESCRIPTOR memory descriptor with all fields cleared. This is rejected by the SubmitResources() implementation of the generic PciHostBridgeDxe in the following way: PciHostBridge: SubmitResources for PcieRoot(0x0) Mem: Granularity/SpecificFlag = 0 / 00 Length/Alignment = 0x0 / 0x0 PciBus: HostBridge->SubmitResources() - Invalid Parameter ASSERT_EFI_ERROR (Status = Invalid Parameter) ASSERT [PciBusDxe] .../PciBusDxe/PciLib.c(561): !EFI_ERROR (Status) So instead, create the empty configuration as a single entry of type EFI_ACPI_END_TAG_DESCRIPTOR.

Phase Tag, SqTdbl/CqHdbl and SqBuffer/CqBuffer should be cleared in NvmeControllerInit() to make HC functionality work when user invokes NvmeBlockIoReset().
