Hello build bot (Jenkins), Raul Rangel, Furquan Shaikh, Marshall Dawson, Jason Glenesk, Angel Pons, Aaron Durbin, Felix Held,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/45050
to look at the new patch set (#8).
Change subject: soc/amd/picasso/acpi: Remove padding in IVRS table caused by realignment. ......................................................................
soc/amd/picasso/acpi: Remove padding in IVRS table caused by realignment.
Previous CL (1916f8969b10e27fe06b3e0eb1caae632bd947f6) misinterpreted spec as requiring size alignment on all IVHD device entries. The correct requirement specifies only for 4-byte entries. The unneeded realignments result in gaps in the table. The kernel hangs in early boot due to the malformed table.
Remove 8-byte entry alignment.
BUG=b:166519072 TEST=Boot fully to morphius board with and without amd_iommu kernel parameter. Confirm IVRS contains no alignment gaps/corruption.
