** Description changed: [ Impact ] On gfx1152 (Kracken) and gfx1153 (Krackan2), GPU may hang when running certain shaders and compute workload. We identified an issue in GC microcode resource assignment logic that root caused it. The fix has been pushed into the latest linux-firmware. See the following. [ Fix ] Update the gfx1152 and gfx1153 in the linux-firmware to the latest: - 1. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdnpu?id=d8fc350033550f348260081594f71c81d67cf1c1 - 2. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdnpu?id=58cf579b98c0c4878deeda1acb5db70e699875b5 + 1. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu?id=e2d3b43db975878ff0724ea7d3806a7615e0eb71 + 2. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu?id=ab1f658c787bd1e80ee5899da32a62b76c8fa162 [ Test ] For Noble: 1. Install oem 6.14, and test the said workload on gfx1152 and gfx1153 platforms. Make sure that GPU doesn't hang. 2. Check basic graphic function on said platforms. For Questing: If there's no ROCm support intended, test basic graphic function may suffice. [ Where problems could occur ] This impacts Karaken and Karaken2 platforms. However internally have QAed the said firmware and kernel using upstream linux-firmware, so hopefully it's less likely that there will be a regression.
