[PATCH xf86-video-ati 2/2] Use reference counting for tracking KMS framebuffer lifetimes
Michel Dänzer
michel at daenzer.net
Wed May 10 09:05:59 UTC 2017
From: Michel Dänzer <michel.daenzer at amd.com>
References are held by the pixmaps corresponding to the FBs (so
the same KMS FB can be reused as long as the pixmap exists) and by the
CRTCs scanning out from them (so a KMS FB is only destroyed once it's
not being scanned out anymore, preventing intermittent black screens and
worse issues due to a CRTC turning off when it should be on).
v2:
* Only increase reference count in drmmode_fb_reference if it was sane
before
* Make drmmode_fb_reference's indentation match the rest of
drmmode_display.h
Reviewed-by: Alex Deucher <alexander.deucher at amd.com> # v1
