Hi everybody, so, I would like us to finally solve the last piece on how to react on channel resets from the kernel side, as this would solve this nasty "Xorg freezes allthough killing the causing application unfreezes it" issue. I have some WIP code which works pretty well if the application isn't listening to vblank events (like glamor or wayland compositors do) and whenever mesa gets notified about a dead channel, it would either simply crash or invoke the robustness callbacks to prevent the application from doing anything stupid after the channel was reset on the kernel side. patches are here: nouveau: https://github.com/karolherbst/nouveau/commits/reset_ntfy libdrm: https://github.com/karolherbst/drm/commits/ctx_reset mesa: https://github.com/karolherbst/mesa/commits/reset_notfy_to_upstream This issue is really pressing as it annoys some users as this issue is very stupid do begin with, because it forces to hard shutdown the machine allthough there is no real need for it, risking data looses and so on. If any of you have better suggestions on how to fix it with the current kernel code, please go ahead. I would like to have a solution which we can easily use on top of already release kernels or stable releases, so there is no dependency on newer kernels/interfaces at all. _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
