2015-03-03OvmfPkg, ArmVirtualizationPkg: clean up XenHypercallLib namesLaszlo Ersek
Perform the following renames in order to stick with edk2 tradition more closely: XenHypercallLibArm, XenHypercallLibIntel -> XenHypercallLib XenHypercallIntel -> X86XenHypercall In addition, we unify the INF files. This patch modifies ArmVirtualizationPkg and OvmfPkg at once, in order to keep both bisectable (client code shouldn't break).

2015-03-02ArmVirtualizationPkg: PlatformIntelBdsLib: lack of QEMU kernel is no errorLaszlo Ersek
When the user doesn't pass a kernel with QEMU's "-kernel" switch, the firmware sees a zero-sized kernel blob via the QemuFwCfgItemKernelSize key; there's no way to distinguish "no kernel" from "zero sized kernel". In both cases TryRunningQemuKernel() proceeds as far as gBS->LoadImage(), which then rejects the zero sized synthetic file with EFI_UNSUPPORTED. This is known and works fully as expected; however we should rather catch the much more frequent "no kernel" case earlier, in order to avoid the EFI_D_ERROR message TryRunningQemuKernel: LoadImage(): Unsupported which is arguably meaningless noise for the "no kernel" case.

2015-02-28ArmVirtualizationPkg: implement custom MemoryInitPeiLibArd Biesheuvel
This implements a MemoryInitPeiLib instance that differs from the stock ArmPlatformPkg version only in the fact that it does not remove the memory used by the flash device (FD). The reason is that, when using PrePi, the DXE core is started immediately and never returns so there is no reason to preserve any of the memory that the flash device occupied originally, and it is preferable to release is so that the OS loader can reuse it. This is especially important for the relocatable PrePi configuration, which is aimed at being launched from a boot loader that itself adheres to the Linux arm64 boot protocol.

In this patch we remove all dependencies on ARM BDS libraries. We also remove empty and/or unneeded functions, includes, etc. PlatformIntelBdsLib "goes back to basics" temporarily -- there are no consoles configured, and it's practically not possible to interact with the user interface. Bisection remains available in the sense that "ArmVirtualizationQemu.dsc" continues to build and should boot preexistent boot options, but user interaction does regress temporarily. The reason for this is that it's preferable to keep this patch and the next one separate for readability's sake -- they amount to a rewrite from scratch.

2015-02-23ArmVirtualizationPkg: PlatformIntelBdsLib: fix multiconsole setupLaszlo Ersek
In the following call chain: PlatformBdsPolicyBehavior() PlatformBdsConnectConsole() InitializeConsolePipe() x 3 BdsConnectDevicePath() [ArmPkg/Library/BdsLib/BdsFilePath.c] the three InitializeConsolePipe() function calls pass through - (&gST->ConsoleOutHandle, &gST->ConOut), - (&gST->ConsoleInHandle, &gST->ConIn), - (&gST->StandardErrorHandle, &gST->StdErr) to BdsConnectDevicePath(), in ArmPkg's BdsLib. At least when more than one console device paths are specified in the ConIn / ConOut / ErrOut variables, the above resuls in: - unchanged protocol interfaces (ConOut, ConIn, StdErr) in the system table (because ConSplitterDxe installs its non-NULL interfaces first), - but, changed handles in the system table. This effectively separates the handle fields in the system table from the protocol interfaces in the same that should always be associated with the handles. The end result is that clients using the handles break (splitting / multiplexing doesn't work for them), while clients directly using the protocol interfaces work. Therefore, do not attempt to connect consoles separately. ConSplitterDxe is dispatched before PlatformBdsPolicyBehavior() is called (the latter happens in the BDS phase), and ConSplitterDxe installs virtual handles and protocol interfaces for input / output / error. BdsLibConnectAll() covers all devices, including consoles; as those consoles are connected, ConPlatformDxe and ConSplitterDxe pick them up nicely as "slaves". We just need to make sure that the variables are set first, for the variables -> ConPlatformDxe -> ConSplitterDxe dependency chain.

The BarExisted() function in "MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c" raises the TPL to TPL_HIGH_LEVEL before accessing PCI config space. The PciExpressLib instance under "MdePkg/Library/BasePciExpressLib" -- serving the PCI config space access -- calls PcdGet64(PcdPciExpressBaseAddress) in turn, for each such call. The PcdGet64() function, when issued at TPL_HIGH_LEVEL, triggers an ASSERT(). PcdGet64() is based on a protocol in this UEFI phase, and protocol handler services are not allowed above TPL_NOTIFY (see Table 23 "TPL Restrictions" in the UEFI spec).

According to Volume 5 of the PI spec, 10.8.2 PCI Host Bridge Resource Allocation Protocol, SubmitResources(), It is considered an error if no resource requests are submitted for a PCI root bridge. If a PCI root bridge does not require any resources, a zero-length resource request must explicitly be submitted. Under MdeModulePkg/Bus/Pci/PciBusDxe/, we have: PciHostBridgeResourceAllocator() [PciLib.c] ConstructAcpiResourceRequestor(..., &AcpiConfig) [PciEnumerator.c] PciResAlloc->SubmitResources(..., &AcpiConfig) ASSERT_EFI_ERROR () If ConstructAcpiResourceRequestor() finds no resources to request (for example because no PCI devices are on the root bridge), it places a zero-length EFI_ACPI_ADDRESS_SPACE_DESCRIPTOR followed by an EFI_ACPI_END_TAG_DESCRIPTOR in "AcpiConfig"; satisfying the PI spec. However, PciHostBridgeDxe's SubmitResources() function does not expect such input; the following part of the code rejects it: switch (Ptr->ResType) { case 0: // // Check invalid Address Sapce Granularity // if (Ptr->AddrSpaceGranularity != 32) { return EFI_INVALID_PARAMETER; } Skip EFI_ACPI_ADDRESS_SPACE_DESCRIPTORs with zero AddrLen early.

Unfortunately, this places memory BARs into MMIO ranges that belong to other devices. (Arguably, their respective drivers should not just add, but immediately allocate those ranges as well.) ( This problem is not seen in OVMF / PcAtChipsetPkg, because there we allocate bottom-up from the range [max(2GB, top-of-low-RAM), 0xFC000000). (See the MMIO resource descriptor HOB created in MemMapInitialization() [OvmfPkg/PlatformPei/Platform.c].) That MMIO range fits in the static [2GB, 4GB) aperture given in "mResAperture" in PcAtChipsetPkg/PciHostBridgeDxe; plus other MMIO ranges (IO-APIC, HPET, LAPIC, flash chip) are higher than 0xFC000000. Hence the bottom-up BAR allocation in OvmfPkg always finds the right MMIO range first. ) In ArmVirtualizationPkg/PciHostBridgeDxe we can solve the problem by working our way downwards from the top of our own aperture.

This change makes no difference for QEMU/TCG, but it is important for QEMU/KVM, at the moment. Because gDS->SetMemorySpaceAttributes() is ultimately implemented by EFI_CPU_ARCH_PROTOCOL.SetMemoryAttributes() -- see "MdeModulePkg/Core/Dxe/Gcd/Gcd.c" and "ArmPkg/Drivers/CpuDxe/" -- we add the CPU architectural protocol to the module's DepEx.

There are two ways for that: - building resource descriptor HOBs in the HOB producer phase (basically, PEI), and letting the DXE core process them, - calling gDS->AddIoSpace() and gDS->AddMemorySpace() during DXE. We opt for the second method for simplicity. In the address space maps, the corresponding ranges change from "nonexistent" to "IO" and "MMIO", from which the gDS->AllocateIoSpace() and gDS->AllocateMemorySpace() services can later allocate PCI BARs.
