boot/edk2: bump to version edk2-stable202405
Release notes: https://github.com/tianocore/edk2/releases/tag/edk2-stable202405 We can't bump to edk2-stable202408 yet due to a runtime issue while testing qemu_aarch64_sbsa_defconfig following the switch generic ArmPsciResetSystemLib [1] ERROR: sbsa_sip_smc_handler: unhandled SMC (0xc20000ca) (function id: 202) Qemu 9.0/9.1 is using a slightly older edk2 firmware based on edk2-stable202405 release [2] that contains a commit [3] fixing a bootloader crash produced with qemu_aarch64_sbsa_defconfig [4] since Qemu 9.0. From [5]: "The version of the sbsa-ref EDK2 firmware we used to use in this test had a bug where it might make an unaligned access to the framebuffer, which causes a guest crash on newer versions of QEMU where we enforce the architectural requirement that unaligned accesses to Device memory should take an exception." This commit [5] is backported to edk2-stable202405. For the same reason, we have to update edk2-platforms to a specific version [6]: "QemuSbsa: enable WriteCombine for the FrameBuffer QEMU no longer permits misaligned access to device memory, which breaks QemuVideoDxe on SbsaQemu. c1d1910be6e04a8b1a73090cf2881fb698947a6e commit in EDK2 fixed it by enabling WriteCombine for Framebuffer memory. This change enables that fix." As a side note, the edk2-non-osi package does not need to be updated, so it is left untouched. Finally, this EDK2 version requires a recent Qemu version. The version included in the reference Docker image (5.2.0) is too old and will not allow to start this EDK2 version. Therefore, this bump is known to be incompatible with runtime tests which are using EDK2 on Aarch64 architecture. At the authoring time of this commit, broken tests are: - tests.boot.test_edk2 - tests.boot.test_grub.TestGrubAArch64EFI - tests.package.test_fwts Note that the EDK2/Qemu incompatibility is only affecting Aarch64 tests. Other tests using EDK2 on i386 or x86_64 are not affected. To prevent this commit introducing broken runtime tests, those have been disabled in a previous commit.

Subject: [PATCH] OvmfPkg/QemuVideoDxe: add feature PCD to remap framebuffer
|
||||
W/C
|
||||
|
||||
Some platforms (such as SBSA-QEMU on recent builds of the emulator) only
|
||||
tolerate misaligned accesses to normal memory, and raise alignment
|
||||
faults on such accesses to device memory, which is the default for PCIe
|
||||
MMIO BARs.
|
||||
|
||||
When emulating a PCIe graphics controller, the framebuffer is typically
|
||||
exposed via a MMIO BAR, while the disposition of the region is closer to
|
||||
memory (no side effects on reads or writes, except for the changing
|
||||
picture on the screen; direct random access to any pixel in the image).
|
||||
|
||||
In order to permit the use of such controllers on platforms that only
|
||||
tolerate these types of accesses for normal memory, it is necessary to
|
||||
remap the memory. Use the DXE services to set the desired capabilities
|
||||
and attributes.
|
||||
|
||||
Hide this behavior under a feature PCD so only platforms that really
|
||||
need it can enable it. (OVMF on x86 has no need for this)
