2018-03-19drm/msm: rename mdp->dispRob Clark1-121/+0
Since new display controller is called "dpu" instead of "mdp". Lets make the name of the toplevel directory for the display controllers a bit more generic. Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Sean Paul <seanpaul@chromium.org>

2015-12-14drm/msm: ratelimit error irq msgsRob Clark1-1/+1
When things go bad and don't recover, we can be getting an err irq every vblank. Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-08-15drm/msm/mdp: Clear pending interrupt status before enable interruptjilai wang1-3/+7
Pending interrupt status needs to be cleared before enable the interrupt. Otherwise it's possible to get a pending interrupt instead of an incoming interrupt. Signed-off-by: Jilai Wang <jilaiw@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-08-15drm/msm: Enable clocks during enable/disable_vblank() callbacksHai Li1-0/+9
AHB clock should be enabled before accessing registers during enable/disable_vblank(). Since these 2 callbacks are called in atomic context while clk_prepare may cause thread sleep, a work is scheduled to control vblanks. v2: fixup spinlock initialization Signed-off-by: Hai Li <hali@codeaurora.org> [add comment about cancel_work_sync() before drm_irq_uninstall()] Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-03-04drm/msm: kexec fixesRob Clark1-0/+5
In kexec environment, we are more likely to encounter irq's already enabled from previous environment. At which point we find that writes to disable/clear pending irq's are slightly less than useless without first enabling clocks. TODO: full blown state read-in so kexec'd kernel can inherit the mode already setup. Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-04-25drm/msm/mdp4: cure for the cursor blues (v2)Rob Clark1-2/+2
The hw cursor is relatively adept at triggering underflows, which manifest as a "blue flash" (since blue is configured as the underflow color). Juggle a few things around to tighten up the timing for setting cursor registers in DONE irq. And most importantly, don't ever disable the hw cursor. Instead flip it to a blank/empty cursor. This seems far more reliable, as even simply clearing the cursor-enable bit (with no other updates in previous/ following frames) can in some cases cause underflow. v1: original v2: add missing locking spotted by Micah Cc: Micah Richert <richert@braincorporation.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-01-09drm/msm: move irq utils to mdp_kmsRob Clark1-126/+16
We'll want basically the same thing for mdp5, so refactor it out so it can be shared. Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-01-09drm/msm: move mdp4 -> mdp/mdp4Rob Clark1-0/+203
There are some little bits and pieces that mdp4 and mdp5 can share, so move things around so that we can have both in a common parent directory. Signed-off-by: Rob Clark <robdclark@gmail.com>
