This new module will later be modified to add a new entry point, more detail in a following commit "OvmfPkg/XenResetVector: Add new entry point for Xen PVH" Value FILE_GUID of XenResetVector have not changed compare to ResetVector because it is a special value (gEfiFirmwareVolumeTopFileGuid).

charset="utf-8" Introduce XenPlatformPei, a copy of OvmfPkg/PlatformPei without some of QEMU specific initialization, Xen does not support QemuFwCfg. This new module will be adjusted to accommodate Xen PVH. fw_cfg dependents that have been removed, which are dynamically skipped when running PlatformPei on Xen: - GetFirstNonAddress(): controlling the 64-bit PCI MMIO aperture via the (experimental) "opt/ovmf/X-PciMmio64Mb" file - GetFirstNonAddress(): honoring the hotplug DIMM area ("etc/reserved-memory-end") in the placement of the 64-bit PCI MMIO aperture - NoexecDxeInitialization() is removed, so PcdPropertiesTableEnable and PcdSetNxForStack are left constant FALSE (not set dynamically from fw_cfg "opt/ovmf/PcdXxxx") - MaxCpuCountInitialization(), PublishPeiMemory(): the max CPU count is not taken from the QemuFwCfgItemSmpCpuCount fw_cfg key; PcdCpuMaxLogicalProcessorNumber is used intact and PcdCpuApInitTimeOutInMicroSeconds is never changed or used. - InitializeXenPlatform(), S3Verification(): S3 is assumed disabled (not consulting "etc/system-states" via QemuFwCfgS3Enabled()). - InstallFeatureControlCallback(): the feature control MSR is not set from "etc/msr_feature_control" (also removed FeatureControl.c as there is nothing been executed) Also removed: - SMRAM/TSEG-related low mem size adjusting (PcdSmmSmramRequire is assumed FALSE) in PublishPeiMemory(), - QemuInitializeRam() entirely, Xen related changes: - Have removed the module variable mXen, as it should be always true. - Have the platform PEI initialization fails if Xen has not been detected.

For this, we replace the empty embedded variable store by a binary array, which is a ELF file header. The ELF header explain to a loader to load the binary at the address 1MB, then jump to the PVH entry point which will be created in a later patch. The header also includes a Xen ELF note that is part of the PVH ABI. That patch include OvmfXenElfHeaderGenerator.c which can be use to regenerate the ELF header, but this will be a manual step.

The goal of the patch is to avoid having to create RAM just below 4G when creating a Xen PVH guest while being compatible with the way hvmloader currently load OVMF, just below 4G. Only the new PVH entry point will do the calculation. The ResetVector will figure out its current running address by creating a temporary stack, make a call and calculate the difference between the build time address and the address at run time. This patch copies and make the necessary modification to some other asm files: - copy of UefiCpuPkg/.../Flat32ToFlat64.asm: Allow Transition32FlatTo64Flat to be run from anywhere in memory - copy of UefiCpuPkg/../SearchForBfvBase.asm: Add a extra parameter to indicate where to start the search for the boot firmware volume.

charset="utf-8" The ACPI Timer isn't present in a PVH guest, but local APIC works on both PVH and HVM. Note that the use of SecPeiDxeTimerLibCpu might be an issue with a driver of type DXE_RUNTIME_DRIVER. I've attempted to find out which of the DXE_RUNTIME_DRIVER uses the TimerLib at runtime. I've done that by replacing the TimerLib evaluation in [LibraryClasses.common.DXE_RUNTIME_DRIVER] by a different one and checking every module that uses it (with the --report-file=3Dreport build option). ResetSystemRuntimeDxe is calling the TimerLib API at runtime to do the operation "EfiResetCold", so this may never complete if the OS have disabled the Local APIC Timer.

charset="utf-8" When running as a Xen PVH guest, there is no CMOS to read the memory size from. Rework GetSystemMemorySize(Below|Above)4gb() so they can work without CMOS by reading the e820 table. Rework XenPublishRamRegions to also care for the reserved and ACPI entry in the e820 table. The region that was added by InitializeXen() isn't needed as that same entry is in the e820 table provided by hvmloader. MTRR settings aren't modified anymore, on HVM it's already done by hvmloader, on PVH it is supposed to have sane default. MTRR will need to be done properly but keeping what's already been done by programmes that has runned before OVMF will do for now. Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=3D1689 Signed-off-by: Anthony PERARD Acked-by: Laszlo Ersek --- Notes: v4: - some coding style - Added AddReservedMemoryRangeHob, and using it. - this patch now replace "OvmfPkg/XenPlatformPei: Reserve hvmloader's m= emory only when it has run" from v3. hvmloader have added an entry in the e820 table, there is no need for a special case. - now, everything that is in the e820 table is added to OVMF's memory map, no more skipping ACPI entries or hvmloader's reserved entries. Instead, we look for the local APIC region and avoid it if it is present in the e820. - rework commit message OvmfPkg/XenPlatformPei/Platform.h | 13 ++++++ OvmfPkg/XenPlatformPei/MemDetect.c | 69 +++++++++++++++++++++++++++++ OvmfPkg/XenPlatformPei/Platform.c | 11 +++++ OvmfPkg/XenPlatformPei/Xen.c | 70 +++++++++++++++++++----------- 4 files changed, 137 insertions(+), 26 deletions(-) diff --git a/OvmfPkg/XenPlatformPei/Platform.h b/OvmfPkg/XenPlatformPei/Pla= tform.h index db9a62572f..7661f4a8de 100644 --- a/OvmfPkg/XenPlatformPei/Platform.h +++ b/OvmfPkg/XenPlatformPei/Platform.h @@ -44,6 +44,13 @@ AddReservedMemoryBaseSizeHob ( BOOLEAN Cacheable );

charset="utf-8" "OvmfPkg/8254TimerDxe" is replaced with a Xen-specific EFI_TIMER_ARCH_PROTOCOL implementation. Also remove 8259InterruptControllerDxe as it is not used anymore. This Timer uses the local APIC timer as time source as it can work on both a Xen PVH guest and an HVM one. Based on the "OvmfPkg/8254TimerDxe" implementation.

charset="utf-8" On a Xen PVH guest, none of the existing serial or console interface works, so we add a new one, based on XenConsoleSerialPortLib, and implemented via SerialDxe. That is a simple console implementation that can works on both PVH guest and HVM guests, even if it rarely going to be use on HVM. Have PlatformBootManagerLib look for the new console, when running as a Xen guest. Since we use VENDOR_UART_DEVICE_PATH, fix its description and coding style. Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=3D1689 Signed-off-by: Anthony PERARD Reviewed-by: Laszlo Ersek --- Notes: v4: - instead of creating a new XEN_CONSOLE_DEVICE_PATH, use the existing VENDOR_UART_DEVICE_PATH. And explain why VENDOR_UART_DEVICE_PATH changed in the commit message. =20 v3: - removed PciSioSerialDxe and IsaSerialDxe from OvmfXen, since they would not be used, maybe, to check. - some coding style fix =20 - not changed: PciSioSerialDxe: even if we add SerialDxe, we still needs PciSioSerialDxe to have OVMF use the emulated serial port on HVM. =20 v2: - Use MdeModulePkg/Universal/SerialDxe instead of something new. - Have PlatformInitializeConsole() look for it by using the known-in-advance device path for the xen console in the PLATFORM_CONSOLE_CONNECT_ENTRY.
