verified linux-firmware/focal-proposed version 1.187.26. ** Description changed:
[SRU Justification] [Impact] On AMD Yellow Carp B0 platforms, S0i3 is still not working. [Fix] This denpends on a few fixes for kernel driver that are all either in v5.17-rc1 or in stable linux-5.1x.y, along with an already upstreamed dmcub firmware. [Test Case] On AMD RMT CRB board, 1. apply both kernel and firmware fixes 2. module blacklist amd_sfh as it's still under development, 3. trigger system suspend. Use power button to wake up the device. 4. check /sys/kernel/debug/amd_pmc/s0ix_stats, the values shall be non-zero On without any of above, the board may not cut device power during suspend, and/or fail to resume and leaving a blank screen, and/or s0ix stats remain all zeros. [Where problems could occur] - So far all the patches can be cleanly applied, and they're being - progressively proposed to linux-stable. + On AMD RMT CRB board, Sensor Fusion Hub (amd_sfh) still doesn't support + S0ix and has to be disabled. For the kernel side, the driver fixes + addressed a few procedure errors that should be unlikely to introduce + regressions; for the firmware side, also tested loading new firmware on + unpatched kernels and there is no difference found yet. [Other Info] For kernel driver fixes, patches for both oem-5.14 and jammy are necessary; for firmware, that has been available in jammy branch but not yet released, so only Focal will be nominated. ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1957026 Title: AMD Yellow Carp DMCUB fw update for s0i3 B0 fixes To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1957026/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
