* ArmVirtPkg/FdtPciHostBridgeLib: Add extra pci root buses supportJiahui Cen via groups.io2021-01-201-18/+4
| | | | | | | | | | | | | | | | | | | | | In order to take advantages of extra pci root buses in ArmVirtPkg, it is necessary to scan extra root buses when getting root briges. And now PciHostBridgeUtilityLib already provides a set of utility functions that support for extra pci root buses, like PciHostBridgeUtilityGetRootBridges() / PciHostBridgeUtilityFreeRootBridges(). So let's rebase ArmVirtPkg/FdtPciHostBridgeLib to PciHostBridgeUtilityGetRootBridges() / PciHostBridgeUtilityFreeRootBridges() to extend ArmVirtPkg with extra pci root buses support.

* ArmVirtPkg: disable list length checks in NOOPT and DEBUG buildsLaszlo Ersek2021-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | In NOOPT and DEBUG builds, if "PcdMaximumLinkedListLength" is nonzero, then several LIST_ENTRY *node* APIs in BaseLib compare the *full* list length against the PCD. This turns the time complexity of node-level APIs from constant to linear, and that of full-list manipulations from linear to quadratic. (See some example OVMF numbers in the previous patch.) Checking list lengths against an arbitrary maximum -- default value, and current ArmVirtPkg setting: 1,000,000 -- seems useless even in NOOPT and DEBUG builds, while the cost is significant; so set the PCD to 0.

* ArmVirtPkg: raise PcdShellFileOperationSize to 128KBLaszlo Ersek2021-01-192-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Some UEFI shell commands read and write files in chunks. The chunk size is given by "PcdShellFileOperationSize", whose default in "ShellPkg/ShellPkg.dec" is 4KB (0x1000). The virtio-fs daemon of QEMU advertizes a 128KB maximum buffer size by default, for the FUSE_WRITE operation. By raising PcdShellFileOperationSize 32-fold, the number of FUSE write requests shrinks proportionately, when writing large files. And when a Virtio Filesystem is not used, a 128KB chunk size is still not particularly wasteful.

* ArmVirtPkg/PlatformCI: stick with "ubuntu-18.04" for nowLaszlo Ersek2020-12-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "vm_image: 'ubuntu-latest'" now refers to Ubuntu Focal (20.04LTS), not Ubuntu Bionic (18.04LTS), according to <https://github.com/actions/virtual-environments/issues/1816>. In Focal, the "qemu" package is a dummy package with no dependencies, and so the actual emulators are not pulled in. Compare: https://packages.ubuntu.com/bionic/qemu https://packages.ubuntu.com/focal/qemu This causes CI runs to fail. It would be best to switch to the "qemu-system" package name, which continues to depend on the emulators: https://packages.ubuntu.com/bionic/qemu-system https://packages.ubuntu.com/focal/qemu-system However, while that package does make the emulators available, the emulators crash. So for now, stick with the previous Ubuntu environment, which continues to be supported, per <https://github.com/actions/virtual-environments/issues/1816>.

* ArmVirtPkg: Support for kvmtool virtual platformSami Mujawar2020-10-162-0/+555
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kvmtool is a virtual machine manager that enables hosting KVM guests. Kvmtool emulates certain devices like serial port, RTC, etc. essentially providing a virtual platform. This patch adds support for kvmtool virtual platform. Following is a brief description of the firmware implementation choices: - Serial Port: 16550 UART On some platforms the 16550 UART is interfaced using PCI. Therefore, the 16550 Serial port library is dependent on the PCI library. The 16550 UART driver checks the Device ID represented using the PCD gEfiMdeModulePkgTokenSpaceGuid.PcdSerialPciDeviceInfo to determine if the UART is behind PCI. If the Device ID is 0xFF then the serial 16550 UART is not behind PCI. On Kvmtool the Serial 16550 UART is not behind PCI, and therefore a combination of BasePciLibPciExpress and BasePciExpressLib is used to satisfy the PCI library dependency. The PcdSerialPciDeviceInfo is also set to 0xFF to indicate that the Serial 16550 UART is not behind PCI. The PCD PcdSerialUseMmio is also set to TRUE to indicate MMIO accesses are required for the UART registers. Additionally two instances of PlatformHookLibs are provided EarlyFdt16550SerialPortHookLib and Fdt16550SerialPortHookLib to patch the PcdSerialRegisterBase so that BaseSerialPortLib16550 and retrieve the base address of the 16550 UART. - Dependency order for Flash FaultTolerantWriteDxe makes use of PCDs (e.g. PcdFlashNvStorageFtwSpareBase64 etc.), which in case of kvmtool will be evaluated based on the CFI flash base address read from the DT. These variables are populated in the NorFlashPlatformLib loaded by ArmVeNorFlashDxe. This results in a dependency issue with FaultTolerantWriteDxe. To resolve this make the NorFlashPlatformLib as a library dependency for FaultTolerantWriteDxe. - RTC Controller A separate patch updates the MC146818 RTC controller driver to support MMIO accesses. A KvmtoolRtcFdtClientLib has been introduced to extract the base addresses of the RTC controller from the platform device tree and map the RTC register space as Runtime Memory.

* ArmVirtPkg: 16550 UART Platform hook librarySami Mujawar2020-10-165-0/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BaseSerialPort16550 library invokes the PlatformHookSerialPortInitialize() implemented as part of the PlatformHook library, to perform platform specific initialization required to enable use of the 16550 device. The BaseSerialPort16550 library uses the PcdSerialRegisterBase to obtain the base address of the UART for MMIO operations. Some VMMs like Kvmtool provide the base address of the console serial port in the platform device tree. This patch introduces two instances of the Platform Hook library: 1. EarlyFdt16550SerialPortHookLib - parses the platform device tree to extract the base address of the 16550 UART and update the PCD PcdSerialRegisterBase. 2. Fdt16550SerialPortHookLib - reads the GUID Hob gEarly16550UartBaseAddressGuid (that caches the base address of the 16550 UART discovered during early stages) and updates the PCD PcdSerialRegisterBase. Note: a. The PCD PcdSerialRegisterBase is configured as PatchableInModule. b. A separate patch introduces a PlatformPeiLib that trampolines the 16550 UART base address from the Pcd PcdSerialRegisterBase to the GUID Hob gEarly16550UartBaseAddressGuid.

* ArmVirtPkg/NorFlashQemuLib: disable NOR flash DT nodes upon discoveryArd Biesheuvel2020-06-241-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our UEFI guest firmware takes ownership of the emulated NOR flash in order to support the variable runtime services, and it does not expect the OS to interfere with the underlying storage directly. So disable the NOR flash DT nodes as we discover them, in a way similar to how we disable the PL031 RTC in the device tree when we attach our RTC runtime driver to it. Note that this also hides the NOR flash bank that carries the UEFI executable code, but this is not intended to be updatable from inside the guest anyway, and if it was, we should use capsule update to do so. Also, the first -pflash argument that defines the backing for this flash bank is often issued with the 'readonly' modifier, in order to prevent any changes whatsoever to be made to the executable firmware image by the guest. This issue has become relevant due to the following Linux changes, which enable the flash driver stack for default build configurations targetting arm64 and 32-bit ARM. ce693fc2a877 ("arm64: defconfig: Enable flash device drivers for QorIQ boards", 2020-03-16). 5f068190cc10 ("ARM: multi_v7_defconfig: Enable support for CFI NOR FLASH", 2019-04-03) Reviewed-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Philippe Mathieu-Daude <philmd@redhat.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@arm.com>

| | | | | | | | | | | | | | | | | | | Instead of having a GCC specific routine to perform self-relocation based on ELF metadata, use the PE/COFF metadata and the existing PeCoff library routines. This reduces the amount of bespoke assembler code that is a burden to maintain, and is not portable across the set of toolchains we support. This does require some special care, as we have no control over how the C code references global symbols, so we need to emit these references from the calling assembler code. Otherwise, they may be emitted as absolute references, in which case they need to be fixed up themselves, leading to a circular dependency.

* ArmVirtPkg: fix ASSERT in ArmVirtGicArchLib with virtualization=onLeif Lindholm2020-03-171-1/+6
| | | | | | | | | | | | | | | | | | | ArmVirtGicArchLib was originally implemented before virtualization emulation was implemented in QEMU, and the GICv2 model implemented only the physical copy of control registers. Enabling virtualization emulation to QEMU adds also the virtual copy, doubling the RegSize returned by FindCompatibleNodeReg () in ArmVirtGicArchLibConstructor (). This triggered an ASSERT when running QEMU with -M virt,virtualization=on. Address this by testing for both possible valid values of RegSize.

Convert source files with LFs in them to CRLF, using "unix2dos". "git show -b" prints no code changes for this patch. (I collected all the file name suffixes in this package, with: $ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev I eliminated those suffixes that didn't stand for text files, then blanket-converted the rest with unix2dos. Finally, picked up the actual changes with git-add.) The CRLF conversion is motivated by "PatchCheck.py".
