* | msm: mdss: properly handle panel on and offXiaoming Zhou2016-03-23
| | | | | | | | | | | | | | | | | | There is some condition that panel off will be called multiple times. In this case, it was blindly free the gpios that were already released. This is adding the check to handle this condition. Change-Id: I0140872be1255fe00ed5abd164a246fa57b2a245 Signed-off-by: Xiaoming Zhou <zhoux@codeaurora.org>
* | msm: mdss: fix the display reset errorXiaoming Zhou2016-03-23
| | | | | | | | | | | | | | | | | | | | Increase the dma stop time out value as stopping operation may take longer than the previous defined value. Gracefully handle the time out condition to allow it to retry when the next frame comes in. Change-Id: I5120f309db2dbaeebef3b2878caa13cec17c9e1f Signed-off-by: Xiaoming Zhou <zhoux@codeaurora.org>
* | msm: mdss: Print task name when fb_open failsDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | Certain process is trying to open the frame buffer node when target shutdown is in progress. This process keeps calling fb_open if request fails. Printing name of the process helps to pinpoint it when user space log is not provided. Change-Id: I83601d478113a7b8ee78c1ee0e79d91c11e59826 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>
* | msm: mdss: Notify userspace of idle screen caseAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Expose two new sysfs nodes - idle_time and idle_notify - that are used to notify userspace whenever the display is idle with no screen updates. The idle_time node needs to be configured with the duration in milliseconds to detect no screen updates. The userspace app can poll on the idle_notify node to get notifications of the idle state.

* | msm: mdss: refactor command mode vsync control logicAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | Current logic is prone to corner case when mdss_mdp_remove_vsync_handler is called twice: once from mdss_mdp_cmd_stop and again from vsync ctrl logic. Need to properly identify the second call and avoid resetting the rdptr ticks which prevent from clocks being turned off properly.

* | msm: mdss: Don't call pan_idle for MSMFB_OVERLAY_PREPARE ioctlRamakant Singh2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | We keep calling MSMFB_OVERLAY_PREPARE for each composition cycle, even if there are no changes in params. Because of this we can hit performance degradation due to pan idle wait. This change removes pan_idle wait for prepare call.

* | msm: mdss: ensure pipe is halted before freeing buffersAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | When pipe is being detached from mixer, there is potential corner case if underrun occurs at the same time which can cause pipe to flood the VBIF. On the other hand unmapping a buffer requires VBIF to be idle to sync TLB, so need to ensure pipe halt is done before freeing the pipe buffers.

| | | | | | | | | | | | | | | | | | | | | | | | | | AD is not configured correctly on dual DSI devices during suspend/resume. The AD configuration data from user space are only copied to the master AD configuration structure, and the AD configuration structure attached to the right mixer (slave AD structure) is never filled. So in the resume function, we cannot use the AD configuration data from the slave AD configuration. Use the one from the master structure instead.

Add PP compat structures to include 32 bit compatible versions of post-processing structures. This allows addition of pp compat ioctl layer.
