It does not make sense to have separate headers for separate static functions. Additionally, we have to add some constants with MSR addresses in subsequent patches. So, make one common place to store them. Signed-off-by: Daniel Kiper <daniel.kiper@oracle.com>
... to grub_rdmsr() and grub_wrmsr() respectively. New names are more obvious than older ones. Signed-off-by: Daniel Kiper <daniel.kiper@oracle.com>
Currently rdmsr and wrmsr commands have own MSR support detection code. This code is the same. So, it is duplicated. Additionally, this code cannot be reused by others. Hence, extract this code to a function and make it public. By the way, improve a code a bit. Additionally, use GRUB_ERR_BAD_DEVICE instead of GRUB_ERR_BUG to signal an error because errors encountered by this new routine are not bugs. Signed-off-by: Daniel Kiper <daniel.kiper@oracle.com>

GRUB_MULTIBOOT(get_mbi_size) doesn't look like an accurate source of the final size, more like a minimal memory buffer size. Signed-off-by: Sergii Dmytruk <sergii.dmytruk@3mdeb.com>
The code makes sure that MBI entry goes first in DRTM, so the payload can measure it first on launch. SLRT table is allocated on the heap first, size for it is reserved inside TXT heap by TXT code and data is later copied into its final place. To avoid mismatch between OS SINIT data MLE size and MLE size from MLE header, take the mle_size from MLE header as is (without aligning it).

This is a rebase of AEM patches on top of https://github.com/rhboot/grub2/commits/fedora-41/, which is based on GRUB 2.12. While Qubes OS uses Fedora 41 by default, it is based on older version of GRUB (
grub2-2.06-124.fc41) which I noticed after doing a rebase, but since it is already done, this is the result. It may be needed if Qubes OS decides to bump the version in the future..github/workflows/build.yml: Build QubesOS packageswas dropped, it won't build anyway due to conflicts in patches.
