* | drm: msm: sde: improve display interface timeout mechanismGuchun Chen2019-04-11
| | | | | | | | | | | | | | | | | | | | | | | | When enabling splash in LK, after kernel boots up, sometimes interface timeout issue may happen. This is caused by kernel's defect when decreasing pending frame kickoff count in vblank isr. As LK and kernel may concurrently flush pipes, so flush_bit may be set by LK, while kernel still treats a timeout issue if it's not 0. This change is to fix the defect.

* drm: msm: sde: reduce black screen duration from null commitGuchun Chen2019-02-26
| | | | | | | | | | | | User may send null commit without any plane attached to kernel. In kernel, these null commits will clear mixer blendstage for all pipes, and power on screen with black background color. However, when bootloader splash is on, this operation will override the splash, which brings long black screen duration between splash and user UI. So this patch is to fix this.

| | | | | | | | | | | | | This change adds the offset to the associated timeline when the retire and release fences are created. The DRM client queries the fences using the atomic commit instead of set_property ioctl. So the sync point should contain the updated timeline before sending the FDs to client.

* drm/msm: support release/retire fence through set propRahul Sharma2019-02-08
| | | | | | | | | | | | | | | | | | Multiple drm clients are allowed to call the get_properties on drm device node. If sde driver creates the fence for each get_property call then it may leave fd leak in client process context because might not be expecting fences. Supporting get_property for only master device may not solve the issue because master client may still call the get_properties multiple times between two commit cycles. This patch supports release/retire fence through set property to avoid fence leak.

* drm/msm: Early DRM DriverCamus Wong2019-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | Add new DRM node to handle early display service. The early DRM driver is to workaround Andriod display framework long boot time problem and DRM single master limitation. The early DRM node provides display function for early application that is outside Android framework. The early application can use early DRM to draw early UI and bootloader review camera menu function. Android framework will not use early DRM node. It will continue to use the main DRM node. Early DRM is another KMS driver that designed for bootup application. Early DRM is not based on SDE framework and it will not initialize display hardware. Early DRM rely on bootloader to initialize display hardware and interfaces. For power and SMMU, early DRM relies on main DRM to initialize them. Early DRM only provide limited display functionality such as RGB buffer display. Early DRM only expected to run during bootup time to work with bootloader/early RVC. When Android UI is ready, early DRM will handoff all display resource to main DRM. After that, no application can open early DRM node. Early DRM is enabled in device tree. User must specify which display to enable early DRM and which display pipes are assigned to eDRM.

* drm/msm/sde: add shared display supportRahul Sharma2019-01-09
| | | | | | | | | | | | | | | | | | | Add support to shared display for panel stacking and split screen application. The current DRM framework only allows one atomic commit for each display, this change will create virtual display pipelines based on the physical display pipeline, and each virtual display can support independent async atomic commit. With the change user mode application can setup and update display on each virtual display and share the same physical port. No mode switch is allowed on virtual display. When all virtual displays are powered off, the physical display will also power off.
