2015-02-25ArmVirtualizationPkg: PlatformIntelBdsLib: detect consoles dynamicallyLaszlo Ersek
Detect the video displays dynamically, and add them to the console and error output variables. Add a short-form, "wild card" USB_CLASS_DEVICE_PATH to the console input variable, which causes the USB keyboard to be handled automatically. Add the fixed location serial console to all of the console input, console output, and error output variables. This patch enables QEMU users to drop "addr=..." PCI address specifications from the -device options (or to use whatever addresses they like). For example, the following works: -device VGA \ \ -device ich9-usb-ehci1,multifunction=on,id=ehci \ -device ich9-usb-uhci1,multifunction=on,masterbus=ehci.0,firstport=0 \ -device ich9-usb-uhci2,multifunction=on,masterbus=ehci.0,firstport=2 \ -device ich9-usb-uhci3,multifunction=on,masterbus=ehci.0,firstport=4 \ -device usb-kbd,bus=ehci.0 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Olivier Martin <olivier.martin@arm.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16924 6f19259b-4bc3-4df7-8a09-765794883524
2015-02-25ArmVirtualizationPkg: PlatformIntelBdsLib: remove ties to ARM BDSLaszlo Ersek
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).

When there are no devices connected to the root bridge, no resources are needed. GetProposedResources() currently considers this an invalid condition (the PI spec doesn't regulate it). Emitting an empty set of EFI_ACPI_ADDRESS_SPACE_DESCRIPTORs, followed by the required EFI_ACPI_END_TAG_DESCRIPTOR, allows PciHostBridgeResourceAllocator() [MdeModulePkg/Bus/Pci/PciBusDxe/PciLib.c] to advance.

2015-02-23ArmVirtualizationPkg/PciHostBridgeDxe: skip 0 AddrLen in SubmitResources()Laszlo Ersek
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.

Quite non-intuitively, we must allow guest-side writes to emulated PCI MMIO regions to go through the CPU cache, otherwise QEMU, whose accesses always go through the cache, may see stale data in the region. 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.

2015-02-23ArmVirtualizationPkg/PciHostBridgeDxe: add room for PCI resource allocationLaszlo Ersek
VirtFdtDxe parses the following address space properties from the DTB (and saves them in PCDs) : ProcessPciHost: Config[0x3F000000+0x1000000) Bus[0x0..0xF] Io[0x0+0x10000)@0x3EFF0000 Mem[0x10000000+0x2EFF0000)@0x0 In order to allow PCI enumeration to allocate IO and MMIO resources from the above ranges for devices, we must add the ranges to the Global Coherency Domain. 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.

2015-02-19OvmfPkg: AcpiPlatformDxe: make dependency on PCI enumeration dynamicLaszlo Ersek
SVN r16411 delayed ACPI table installation until PCI enumeration was complete, because on QEMU the ACPI-related fw_cfg files should have been downloaded only after PCI enumeration. Said commit implemented the dependency by tightening the module's depex. This patch replaces the EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL depex with a matching protocol registration callback. The depex was static, and it could not handle dynamically discovered situations when the dependency would turn out invalid. Namely: - At the moment, the depex in "QemuFwCfgAcpiPlatformDxe.inf" assumes that "ArmPlatformPkg/ArmVirtualizationPkg/ArmVirtualizationQemu.dsc" lacks PCI support. However, PCI support is about to become run-time discoverable on that platform. If PCI support is missing, then ArmVirtualizationPkg will set PcdPciDisableBusEnumeration to TRUE. Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the dependency by not registering the callback and installing the ACPI tables right away. - InitializeXen() in "OvmfPkg/PlatformPei/Xen.c" sets PcdPciDisableBusEnumeration to TRUE. This causes PciBusDriverBindingStart() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciBus.c" to set gFullEnumeration to FALSE, which in turn makes PciEnumerator() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumerator.c" branch to PciEnumeratorLight(). The installation of EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL at the end of PciEnumerator() is not reached. Which means that starting with SVN r16411, AcpiPlatformDxe is never dispatched on Xen. Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the dependency by not registering the callback and installing the ACPI tables right away.
