@zygoon @hrw are the #amazon #aws images expecting a particular machine configuration or are they generally #sbsa compliant? The #graviton chips are essentially #neoverse cores underneath and we model them in TCG.

I found out that SBSA Reference Platform while used with Neoverse-N2/max cpu **nearly** passes BSA/SBSA ACS for SBSA level 3.

Other cores lack Secure-EL2 feature so they fail at BSA test 304/352 (check for Secure-EL2 or stage1/stage2 support in SMMU).

QEMU can emulate stage1 or stage2 support but not both at same time.

UPDATE: after manual checks turned out that lack of system timers sneaked under my radar. B_WAK_06/07/10/11 tests fail.

RISC-V community wonders which way to with emulation. I hope that they follow AArch64 steps:

- virt for virtualization in cloud etc
- sbsa-ref for reference platform

I have added column showing SBSA Reference Platform (sbsa-ref) status to https://marcin.juszkiewicz.com.pl/download/tables/bsa-sbsa.html page.

It has all (S)BSA requirements listed with ACS test numbers added.

Last week was BSD on SBSA Reference Platform week.

I did FreeBSD and found one bug in QEMU, and it looks like one backport from FreeBSD 14 to 13.x will be needed.

NetBSD 9 may get backport from 10 to make it boot at all.

OpenBSD 7.3 went smooth. Once I updated firmware.
