* | | msm: mdss: protect retire count with mutex lockDhaval Patel2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The retire timeline counter in command mode is used by vsync worker queue, validate/commit ioctl thread and overlay off. However, this counter is not protected with any locking mechanism and each thread updates the value. Race condition with updated value between two thread can lead to invalid vsync operation or list corruption. This change protects the counter with mutex lock to avoid all such race conditions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for CEC commands to suspend and resume the device. The HDMI core must be kept on when the CEC wakeup feature is enabled and the device is going into suspend state. Furthermore, interrupts must be enabled in this state to capture CEC commands. This allows the device to be resumed later on via CEC wakeup commands. Change-Id: Ie6fcbc666e4f40335ab8faaa969d4b03aa83e17c Signed-off-by: Tatenda Chipeperekwa <tatendac@codeaurora.org>
* | | msm: mdss: dsi: ensure clocks are off when setting their sourceAbhinav Kumar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When DSI panel in unblanked, the driver configures the sources for all the DSI branch clocks based on the current HW configuration. This assumes that the clocks would be off when the panel is unblanked. This may not be true when transitioning to ON state from any of the panel low power states (LP1 or LP2). This can lead to warnings when trying to set the clock source while the clock is enabled. Fix this by ensuring that the clock source is configured only if the panel is not on.

* | | msm: mdss: dsi: ensure lanes are idle prior to ULPS entryAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that the ULPS entry request can potentially overlap with the last DCS command that was sent out on the link. This is more likely if the DCS command was sent in LP mode. In such cases, the panel could see some issues in the LP transmission which may trigger an error when a BTA is done subsequently. To address this, ensure that the lanes are idle by checking that all active FIFOs are empty and the all active data lanes are in stop state.

Add these optimizations and avoid ULPS configuration for such cases.

That can lead to race condition in vsync handler. -> Core 0: vsync handler thread checks the ctl power status and get preempted by other priority task. -> Core 1: processes the ctl_stop and power off the display device. -> Core 0: Vsync handler task gets chance to run again and tries to access the ctl->op members. The third step leads to invalid structure member access because display is already powered off. This race condition should be fixed by moving all power state checks inside mutex lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid clock off from delayed off when kickoff is pending. This sequence is leading to mdp clocks off and on which adds extra delay in kickoff cycle. Change-Id: Ia30ec3ac3c2e7602a32c9eb789cd85d4736b6c60 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There can be race condition possible between Early touch event thread and kickoff thread. For ex: -> Eary touch event: Turns on clock and schedule the off after 4 vsync cycle. -> Kickoff thread: Leaves the clock on -> Second touch event: Reschedule the clock off workque The second touch event call scheduling the clock off after 4 vsync cycle. On loaded system, kickoff thread might get intruppted and get chance to rerun after 4 vysnc cycle. The clocks will be turned off for such use cases before PP done ISR.

* | | msm: mdss: cleanup auto-refresh implementationIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto-refresh is used on smart displays to refresh display without SW intervention, similar to dumb displays. So when it is on, display controller will automatically send new frame every time panel TE signal is received. Now as per the HW implementation, disabling auto-refresh requires that display controller is idle and there is no frame transfer on-going. To achieve this, we need to follow certain disable sequence. To implement this disable sequence, clean up current implementation and introduce auto-refresh state machine.
