* | msm: mdss: refactor ot limits to support rd and wrIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code only supports to configure the same read and write ot limits. For newer platforms it is needed to configure different default limits for each of the operations. This patch refactors the implementation so the driver can support a different default limit for the read and the write operations.

* | msm: mdss: fix cursor alloc and setupIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Each pipe holds a list with the addresses to the planes allocated for each pipe. Current code was missing to populate this list for the cursor and update the global list with the correct index for the cursor allocated. This change fixes this issue by populating the list and updating the global cursors list. Change-Id: Ib5bdfd5a93802c05643b74a6ebf396d2d9308365 Signed-off-by: Ingrid Gallardo <ingridg@codeaurora.org>
* | msm: mdss: fix check for hardware cursor mixer stageAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently max target zorder is used to check where hw cursor needs to be setup since it needs to be setup at highest mixer stage for target. However max target zorder reflects the maximum number of layers supported and not the actual mixer stage. Fix by doing proper check and configuring right mixer stage for cursor.

* | msm: mdss: reduce rotator fps for high resolutionIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 4k video playback, video only expects to decode at 30fps for current target. This means that rotator is only expected to run at 30fps for 4k resolutions, this change considers this for the rotator bandwidth calculation in order to optimize the bandwith vote.

* | msm: mdss: enable partial update with ping-pong splitUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | When ping-pong split is enabled, frame-buffer is not split and user-land program is not aware that at lower level there are two physical panels. Because of this, user-land will always send a single ROI covering the entire frame-buffer. In such cases, it is driver's responsibility to split the ROI into two when ROI is crossing mid-point and make topology changes when ROI is only on left or right panel. Add these changes to support partial update with ping-pong split. Change-Id: I3fa1beac2f7e9700d5b3a3d4fda63078f1e6e976 Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | In the current implementation, when the display is blanked, DSI phy is turned off prior to turning off the supply to the panel. This results in an abrupt transition on the DSI lanes from LP11 to LP00 which is in violation of the MIPI spec, and can potentially cause panels to go to a bad state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If MDSS idle power collapse feature is enabled, MDSS GDSC can get toggled when exiting idle power collapse. This may require an explicit call to TZ to restore MDSS security configs prior to accessing any MDSS registers, which is typically done whenever IOMMU is attached. For panels where backlight is controlled using DCS commands, it is possible that a backlight update could be triggered when MDSS is power collapsed. This would result in enabling MDSS GDSC and restoring DSI registers prior to sending the DCS commands. For such use cases, ensure that IOMMU is attached prior to any register programming to avoid any crashes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For command mode panels, current code configures the HW to transfer a frame and returns the commit context without waiting for transfer to finish. As an example, after kicking off frame N transfer, commit context doesn't wait for Frame N's transfer to finish. By doing so, it allows SW to configure/queue frame (N+1) and improves the performance. But before frame (N+1) is kicked off, SW needs to make sure that frame N is finished otherwise it may lead to tearing and/or unknown behavior. This is achieved by calling wait4pingpong routine. But this optimization has a side effect when debugging critical issues. If for some reason, frame N had a bad HW configuration and it had HW hang then wait4pingpong during frame (N+1) will timeout. This timeout will lead to HW register dumps but this register dump is related frame (N+1) and not frame N. This gives incorrect debug information. To overcome this side effect, allow wait4pingpong's timing to change using debugfs. Setting this node to true will make the driver to run this processing in a synchronous way, setting it to false will return the driver to normal asynchronous operation: echo 1 > /<debugfs>/mdp/serialize_wait4pp -> sync echo 0 > /<debugfs>/mdp/serialize_wait4pp -> async (default) Change-Id: Ief25232b65cf3dfec7c2147120dac57d0f54d22f Signed-off-by: Ingrid Gallardo <ingridg@codeaurora.org> [cip@codeaurora.org: Use debugfs_create_u32 for wait4pp] Signed-off-by: Clarence Ip <cip@codeaurora.org>

* | msm: mdss: Add gamma correction support in mdp3Krishna Chaitanya Parimi2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add gamma correction support in mdp3 driver via MSMFB_MDP_PP ioctl. The ioctl has been extended to program luts corresponding to histogram based outputs and gamma correction based on flag. The gain corresponding to gamma correction and the histogram based output are combined in driver and applied to hardware.

| | | | | | | | | | | | | | | | | | | | | | For the new versioned PP framework with config payload pointers, the Disable operation should be highest priority and allow a feature to be disabled without requiring a config payload. Gamut Mapping had no check to see if Disable operation was present before throwing error for a NULL payload. Now, Disable op is checked first.
