Change in coreboot[master]: cbfstool/linux_trampoline: Fill the ACPI RSDP entry
by Arthur Heymans (Code Review) 04 Mar '22

04 Mar '22

Hello Arthur Heymans, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/62574 to look at the new patch set (#2). Change subject: cbfstool/linux_trampoline: Fill the ACPI RSDP entry ...................................................................... cbfstool/linux_trampoline: Fill the ACPI RSDP entry With LinuxBoot Linux relied on the legacy method of fetching the RSDP pointer to get ACPI. This uses a more modern approach available since 2018 on the Linux kernel, which involves filling in the zero page. This method takes precedence over any other method of fetching the RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are threatening that legacy code will be removed from Linux so it's best to already adapt to that possibility. Tested on Qemu: - With qemu the RSDP always is in the EBDA - With a fake pointer Linux correctly does not find RDSP Change-Id: I688b94608b03b0177c42d2834c7e3beb802ae686 Signed-off-by: Arthur Heymans <arthur(a)aheymans.xyz> --- M util/cbfstool/linux_trampoline.S M util/cbfstool/linux_trampoline.c 2 files changed, 21 insertions(+), 9 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/74/62574/2 -- To view, visit https://review.coreboot.org/c/coreboot/+/62574 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I688b94608b03b0177c42d2834c7e3beb802ae686 Gerrit-Change-Number: 62574 Gerrit-PatchSet: 2 Gerrit-Owner: Arthur Heymans <arthur.heymans(a)9elements.com> Gerrit-CC: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-CC: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-MessageType: newpatchset

Change in coreboot[master]: cbfstool/linux_trampoline: Fill the ACPI RSDP entry
by Arthur Heymans (Code Review) 04 Mar '22

04 Mar '22

Attention is currently required from: Arthur Heymans. Hello Arthur Heymans, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/62574 to review the following change. Change subject: cbfstool/linux_trampoline: Fill the ACPI RSDP entry ...................................................................... cbfstool/linux_trampoline: Fill the ACPI RSDP entry With LinuxBoot Linux relied on the legacy method of fetching the RSDP pointer to get ACPI. This uses a more modern approach available since 2018 on the Linux kernel, which involves filling in the zero page. This method takes precedence over any other method of fetching the RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are threatening that legacy code will be removed from Linux so it's best to already adapt to that possibility.
