      drm/msm: drop redundant output in debug message · a7c07690
      由 Nicholas Mc Guire 提交于 
      wait_for_completion_timeout returns 0 in case of timeout so printing the
return value here will always yield 0 and is therefor redundant - dropped.

      drm/msm: fix HZ dependency of timeout · 84c3b87b
      由 Nicholas Mc Guire 提交于 
      The timeout is passed as a constant which makes it HZ dependent because
jiffies are expected so it should be converted to jiffies. The actual
value is not clear from the code - my best guess is that this should be
300 milliseconds given that other timeouts are in milliseconds based on
looking at other drm drivers (e.g. exynos_drm_dsi.c:356 300ms,
tegra/dpaux.c:188 250ms) - this needs to be confirmed by someone who
knows the details of the driver.

      drm/msm: fixup wait_for_completion_timeout handling · 9f68ef90
      由 Nicholas Mc Guire 提交于 
      wait_for_completion_timeout return >= 0 but never negative so the check
logic looks inconsistent. Further the return value of
wait_for_completion_timeout was being passed up the call chain but the
x call sites as drm_dp_i2c_do_msg()/drm_dp_dpcd_access() check for < 0
thus timeout was being treated as success case.

<snip> drivers/gpu/drm/drm_dp_helper.c:drm_dp_i2c_do_msg()
                mutex_lock(&aux->hw_mutex);
                ret = aux->transfer(aux, msg);
                mutex_unlock(&aux->hw_mutex);
                if (ret < 0) {
<snip>
logic in edp_aux_transfer() seems incorrect as it could return 0 (timeout)
but checks of <= 0 to indicate error so the return probably should be
-ETIMEDOUT in case wait_for_completion_timeout returns 0 (timeout
occurred).

      drm/msm/mdp5: fix for crash in disable path · e5989ee1
      由 Rob Clark 提交于 
      Seems like disable can race with complete_flip() in process of disabling
a crtc, leading to:

It makes no sense to free the ctl without disabling all stages, so lets
just move them together to avoid the crash.

      drm/msm: adreno a306 support · de558cd2
      由 Rob Clark 提交于 
      As found in apq8016 (used in DragonBoard 410c) and msm8916.

Note that numerically a306 is actually 307 (since a305c already claimed
306).  Nice and confusing.

      drm/msm: clarify downstream bus scaling · 6490ad47
      由 Rob Clark 提交于 
      A few spots in the driver have support for downstream android
CONFIG_MSM_BUS_SCALING.  This is mainly to simplify backporting the
driver for various devices which do not have sufficient upstream
kernel support.  But the intentionally dead code seems to cause
some confusion.  Rename the #define to make this more clear.

      Using fb modifier flag, support NV12MT format in MDP4.

v2:
- rework the modifier's description [Daniel Vetter's comment]
- drop .set_mode_config() callback [Rob Clark's comment]
v3:
- change VENDOR's name and restrict usage to NV12 [pointed by Daniel]

      drm/msm/adreno: dump scratch regs and other info on hang · 26716185
      由 Rob Clark 提交于 
      Dump a bit more info when the GPU hangs, without having hang_debug
enabled (which dumps a *lot* of registers).  Also dump the scratch
registers, as they are useful for determining where in the cmdstream
the GPU hung (and they seem always safe to read when GPU has hung).

Note that the freedreno gallium driver emits increasing counter values
to SCRATCH6 (to identify tile #) and SCRATCH7 (to identify draw #), so
these two in particular can be used to "triangulate" where in the
cmdstream the GPU hung.
