* Fix bug on SRIOV ReservedBusNum when ARI enable.Foster Nong2022-10-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 = PciDevicePresent ( PciRootBridgeIo, &Pci, StartBusNumber, Device, Func ); ... 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.

| | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2303 Whenever a PCI device is discovered, PCI bus calls the EDKII_DEVICE_SECURITY_PROTOCOL to authenticate it. If the function returns success, the PCI bus allocates the resource and installs the PCI_IO for the device. If the function returns fail, the PCI bus skips the device. It is similar to EFI_SECURITY_ARCH_PROTOCOL, which is used to verify an EFI image.

* MdeModulePkg/PciBus: Shadow option ROM after BARs are programmedRuiyu Ni2018-12-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1376 Today's implementation reuses the 32bit MMIO resource requested by all PCI devices MMIO BARs when shadowing the option ROM. Take a simple example, a system has only one PCI device. It requires 8MB 32bit MMIO and contains a 4MB option ROM. Today's implementation only requests 8MB (max of 4M and 8M) 32bit MMIO from PciHostBridgeResourceAllocation protocol. Let's assume the MMIO range [3GB, 3GB+8MB) is allocated. The 3GB base address is firstly programmed to the option ROM BAR for option ROM shadow. Then the option ROM decoding is turned off and 3GB base address is programmed to the 32bit MMIO BAR. It doesn't cause issues when the device doesn't request too much MMIO. But when the device contains a 64bit MMIO BAR which requests 4GB MMIO and a 4MB option ROM. Let's assume [3GB, 3GB+8MB) 32bit MMIO range is allocated for the option ROM. When the option ROM is being shadowed, 64bit MMIO BAR is programmed to value 0, which means [0, 4GB) MMIO is given to the 64bit BAR. The range overlaps with the option ROM range which may cause the device malfunction (e.g.: option ROM cannot be read out) when the device has two separate decoders: one for MMIO BAR, the other for option ROM. The patch requests dedicated MEM32 resource for Option ROMs and moves the Option ROM shadow logic after all MMIO BARs are programmed. The MMIO BAR setting to 0 when shadowing Option ROM is also skipped because the MMIO BAR already contains the correct value.

* MdeModulePkg/PciBus: do not improperly degrade resourceRuiyu Ni2016-05-231-1/+2
| | | | | | | | | | | | | | | | | PciBus driver originally always degrade (64->32) the MMIO resource for PCI BAR when the PCI device contains option ROM. But the degrade causes the PCI device can only use resource below 4GB which makes the resource allocation fails when the PCI device wants very big MMIO. The patch follows the PI spec (ECR 1529) to honor the granularity setting for PCI BAR from IncompatiblePciDeviceSupport so that even for PCI device which contains option ROM, the degrade doesn't happen if IncompatiblePciDeviceSupport returns 64 as granularity.
