drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_frambuffer.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_framebuffer.h. Quite a few placs do currently depend on drm_framebuffer.h without actually including it directly. All of those need to be fixed up. v2: Fix up msm some more v2: Deal with ingenic and shmobile as well Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220614095449.29311-1-ville.syrjala@linux.intel.com Acked-by: Sam Ravnborg Acked-by: Jani Nikula

drm/msm: Fix dirtyfb refcounting

2022-03-07T03:28:47+00:00

refcount_t complains about 0->1 transitions, which isn't *quite* what we wanted. So use dirtyfb==1 to mean that the fb is not connected to any output that requires dirtyfb flushing, so that we can keep the underflow and overflow checking.

drm/msm: Avoid dirtyfb stalls on video mode displays (v2)

2022-02-25T15:59:58+00:00

Someone on IRC once asked an innocent enough sounding question: Why with xf86-video-modesetting is es2gears limited at 120fps. So I broke out the perfetto tracing mesa MR and took a look. It turns out the problem was drm_atomic_helper_dirtyfb(), which would end up waiting for vblank.. es2gears would rapidly push two frames to Xorg, which would blit them to screen and in idle hook (I assume) call the DIRTYFB ioctl. Which in turn would do an atomic update to flush the dirty rects, which would stall until the next vblank. And then the whole process would repeat. But this is a bit silly, we only need dirtyfb for command mode DSI panels. So track in plane state whether dirtyfb is required, and track in the fb how many attached planes require dirtyfb so that we can skip it when not required. (Note, mdp4 does not actually have cmd mode support.)

drm/msm: Move FB debug prints to drm_dbg_state()

2021-06-23T14:32:15+00:00

These are verbose prints that tell us about the framebuffer state. Let's move them to drm_dbg_state() so that they're only printed if we're interested in verbose state logging while drm debugging.

drm/msm: Improved debugfs gem stats

2021-04-07T18:05:43+00:00

The last patch lost the breakdown of active vs inactive GEM objects in $debugfs/gem. But we can add some better stats to summarize not just active vs inactive, but also purgable/purged to make up for that.

drm/msm: remove _unlocked suffix in drm_gem_object_put_unlocked

2020-05-19T21:31:33+00:00

Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: Rob Clark Cc: Sean Paul Cc: David Airlie Signed-off-by: Emil Velikov Acked-by: Sam Ravnborg Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20200515095118.2743122-25-emil.l.velikov@gmail.com

drm/msm: drop use of drmP.h

2019-09-03T23:16:57+00:00

Drop the deprecated drmP.h header file, and trim msm_drv.h to the relevant include files. This resulted in a suprisingly many edits as many files relied on headers included via msm_drv.h. But msm_drv.h is not supposed to carry include files it do not need, so the individual files have to include what extra they needs. v2: - Rebased on top of https://gitlab.freedesktop.org/drm/msm.git msm-next Signed-off-by: Sam Ravnborg Cc: Rob Clark Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Cc: Jordan Crouse Cc: Jeykumar Sankaran Cc: Bruce Wang Cc: Shayenne Moura Cc: Mamta Shukla Cc: Jonathan Marek Cc: Carsten Behling Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Paul Kocialkowski Cc: Sibi Sankar Cc: Todor Tomov Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/20190804065551.GA5211@ravnborg.org
