Public bug reported: [SRU Justification]
[Impact] On Strix and Strix Halo APUs a hang is observed if the suspend sequence is started while running any compute tasks (such as ROCm). This is because the compute ring is not drained when the suspend sequence is started meaning there may be pending fences. Leaving fences pending during s0i3 sequence can hang the GPU. [Fix] * The following series: https://lore.kernel.org/amd-gfx/[email protected]/T/#m7354d41cef682829469dbdb7df8e66d43f20de96 * 54f7a24e1437d66c9ff36d727a9dff1beeeab429 * f33044952c24f85a1527f91440b89d4423840de2 [Test Case] Suspend system with KFD work running. Suspend system without KFD work running. [Where problems can go wrong] Hang during suspend sequence (IE not fix the issue). ** Affects: linux-oem-6.14 (Ubuntu) Importance: Undecided Status: New ** Tags: originate-from-2123893 ** Tags added: originate-from-2123893 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2125019 Title: system hang observed when running compute over s0i3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.14/+bug/2125019/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
