[PATCH 1/2] drm/fb_helper: Add drm_fb_helper_output_poll_changed_with_rpm()
...d focus on the latter two.
As said I'm unfamiliar with MST but browsing through drm_dp_mst_topology.c
I notice that drm_dp_mst_link_probe_work() is the ->work element in
drm_dp_mst_topology_mgr() and is queued on HPD. I further notice that
the work item is flushed on ->runtime_suspend:
nouveau_pmops_runtime_suspend()
nouveau_do_suspend()
nouveau_display_suspend()
nouveau_display_fini()
disp->fini() == nv50_display_fini()
nv50_mstm_fini()
drm_dp_mst_topology_mgr_suspend()
flush_work(&mgr->work);
And before the work item is flushed, the HPD source is quiesced.
So i...

[PATCH] acpi: allow non-optimus setups to load vbios from acpi
Hi, same for me. The screen does not freeze anymore and the boot
succeeds. But now I have this kernel message during boot (for the second
card):
[ 24.382045] pci_pm_runtime_suspend():
nouveau_pmops_runtime_suspend+0x0/0xe0 [nouveau] returns -22
Do you want to have the complete dmesg log? I think this is a new bug.
Your patch works for the previous one, so you can close it.
Yours,
Claas

[PATCH] drm/nouveau: handle -EACCES runtime PM return code
pm_runtime_get*() may return -EACCESS to indicate a device does not have
runtime PM enabled. This is the case when the nouveau.runpm parameter is
set to 0, and is not an error in that context. Handle this case without
failure.
