Second iteration of my endeavour to rid nouveau, radeon and amdgpu of runtime pm ref leaks. Patches 1 to 8 are identical to v1. Patch 9 of v1 modified the DRM core to turn off all CRTCs on driver unload. Based on feedback by Daniel Vetter, I've replaced this with a helper to turn off all CRTCs, which is called by nouveau, radeon and amdgpu on unload. In other words, this is now opt-in. So patch 9 of v1 is replaced with new patches 9 to 12. A by-product of patch 9 is a helper...

http://bugs.freedesktop.org/show_bug.cgi?id=19854 Summary: xscreensaver fails to run (regression) Product: xorg Version: 7.4 Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy:

...n a CRTC being "disabled" and simply having it's DPMS turned off. This is problematic though, because if DPMS is turned off you can't really use the CRTC as a normal CRTC anyway since page flipping and vblanks will be non-functional. As a result, we've been considering DPMS-on CRTCs as enabled and attempt to perform pageflips, vblank waits, etc. on them which inevitably fails. and usually breaks the display the first time any of the CRTCs have their DPMS turned on. This was a problem that didn't really show itself until kernel 4.10 when atomic modesetting was added which...

In multi-x-screen ZaphodHeads configurations, there isn't a one-to-one mapping of kernel provided drmmode crtc index to the index of the corresponding xf86Crtc inside the xf86CrtcConfig crtc array anymore, ie. for kernel provided drmmode->mode_res->crtcs[i], the i'th crtc won't correspond to the xf86Crtc in the i'th slot of the x-screens xf86CrtcConfig anymore, once ZaphodHeads has only selected a subset of all crtcs of a graphics card for a given x-screen, instead of all crtcs. This breaks the mapping of bit positions in the bit masks...
