2014-07-03EmulatorPkg/EmuSimpleFileSystemDxe: Fix incorrect return values upon ↵Paulo Alcantara
allocation failure In EmuSimpleFileSystemOpenVolume() function - in case an allocation failed with AllocatePool() - EFI_UNSUPPORTED was being returned instead of EFI_OUT_OF_RESOURCES, which is incorrect. Even worse, in EmuSimpleFileSystemDriverBindingStart(), an unitiliasied variable (Status) will be returned in case of an allocation failure with AllocateZeroPool(). This patch fixes both issues by correctly returning EFI_OUT_OF_RESOURCES.

2014-06-19OvmfPkg: AcpiPlatformDxe: don't rely on unstable QEMU interfaceLaszlo Ersek
The fw_cfg file "etc/acpi/tables" is not a stable guest interface -- QEMU could rename it in the future, and/or introduce additional fw_cfg files with ACPI payload. Only the higher-level "etc/table-loader" file is considered stable, which contains a sequence of commands to assist firmware with reading QEMU ACPI tables from the FwCfg interface. Because edk2 provides publishing support for ACPI tables, OVMF only uses the Allocate command to find the names of FwCfg files to read and publish as ACPI tables.

In one of the next patches we'll start scanning all fw_cfg files that QEMU advertises as carrying ACPI tables, not just "etc/acpi/tables". The RSD PTR table is known to occur in the "etc/acpi/rsdp" fw_cfg file.

2014-06-19The following call tree exposes a bug in the lifetime (ie. too lateAlex Williamson
creation) of PciIoDevice->DevicePath. The bug can be triggered when PciBusDxe is built into OVMF, with qemu/KVM device assignment of a PCI-express device on the default 440FX machine type. OVMF correctly discovers that the device is PCIe and begins probing extended configuration space for the device. The root bridge has no way to access extended config space and correctly errors, sending us into the error reporting chain seen below. It's possible that this error path could also be reproduced on physical hardware when a PCI-to-PCIe bridge is present.

Fix it by moving CreatePciDevicePath() into CreatePciIoDevice(), allowing PciIoDevice->DevicePath to be initialized before we begin probing the device capabilities: GatherDeviceInfo() | GatherPpbInfo() | GatherP2CInfo() [MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c] CreatePciIoDevice() [MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c] AllocateZeroPool() CreatePciDevicePath() [MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c] sets PciIoDevice->DevicePath -----------+ LocateCapabilityRegBlock() | [MdeModulePkg/Bus/Pci/PciBusDxe/PciCommand.c] PciIoDevice->IsPciExp = TRUE | LocatePciExpressCapabilityRegBlock() | [MdeModulePkg/Bus/Pci/PciBusDxe/PciCommand.c] PciIoConfigRead() via funcptr | [MdeModulePkg/Bus/Pci/PciBusDxe/PciIo.c] RootBridgeIoPciRead() via funcptr | [PcAtChipsetPkg/PciHostBridgeDxe/PciRootBridgeIo.c] FAILS | REPORT_STATUS_CODE_WITH_DEVICE_PATH() | [MdePkg/Include/Library/ReportStatusCodeLib.h] ReportStatusCodeWithDevicePath() | [MdeModulePkg/Library/DxeReportStatusCodeLib/ReportStatusCodeLib.c] ASSERT (DevicePath != NULL) <-----+ Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15567 6f19259b-4bc3-4df7-8a09-765794883524
