* Since commit c161dfb EVE runs VMs with TPM 2.0 device enabled, and it can cause VMs to fail to boot with the below assertion, reason is that if there is not enough contiguous memory available, the ACPI table is relocated but some table offsets, including tpm table are not updated. This is not always the case and the failure shows up only if the app assigned memory is too small (triggers the relocation), for example testing Ubuntu 20.04 and 22.04 images with memory lower than 4GB triggers the issue. * This patch fixes the bios linker loader assert: "bios_linker_loader_add_checksum: Assertion `start_offset < file->blob->len' failed." * This patch is base on the following commit, This has been part of the qemu mainline since v6.1.0 release : qemu/qemu@bb9feea Signed-off-by: Shahriyar Jalayeri <[email protected]>

Since commit c161dfb EVE runs VMs with
TPM 2.0 device enabled, and it can cause VMs to fail to boot with the
below assertion, reason is that if there is not enough contiguous memory
available, the ACPI table is relocated but some table offsets, including
tpm table are not updated. This is not always the case and the failure
shows up only if the app assigned memory is too small (triggers the relocation),
for example testing Ubuntu 20.04 and 22.04 images with memory lower than
4GB triggers the issue.
This patch fixes the bios linker loader assert:
"bios_linker_loader_add_checksum: Assertion `start_offset < file->blob->len' failed."
This patch is base on the following commit, This has been part of the
qemu mainline since v6.1.0 release :
