| * drm/msm: dpu: Don't queue the frame_done watchdog for cursorSean Paul2019-04-181-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case of an async/cursor update, we don't wait for the frame_done event, which means handle_frame_done is never called, and the frame_done watchdog isn't canceled. Currently, this results in a frame_done timeout every time the cursor moves without a synchronous frame following it up before the timeout expires. Since we don't wait for frame_done, and don't handle it, we shouldn't modify the watchdog.

| * drm/msm: dpu: Untangle frame_done timeout unitsSean Paul2019-04-183-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exists a bunch of confusion as to what the actual units of frame_done is: - The definition states it's in # of frames - CRTC treats it like it's ms - frame_done_timeout comment thinks it's Hz, but it stores ms - frame_done timer is setup such that it _should_ be in frames, but the timeout is super long So this patch tries to interpret what the driver really wants. I've de-centralized the #define since the consumers are expecting different units. For crtc, we just use 60ms since that's what it was doing before. Perhaps we could get fancy and scale with vrefresh, but that's for another time. For encoder, fix the comments and rename frame_done_timeout so it's obvious what the units are. In practice, frame_done_timeout is really just checked against 0 || !0, which I guess is why the units being wrong didn't matter. I've also dropped the timeout from the previous 60 frames to 5. That seems like more than enough time to give up on a frame, and my guess is that no one intended for the timeout to _actually_ be 60 frames.

| * drm/msm: dpu: Simplify frame_done watchdog timeout calculationSean Paul2019-04-181-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | Instead of setting the timeout and then immediately reading it back (along with the hand-rolled msecs_to_jiffies calculation), just calculate it once and set it in both places at the same time.

| * drm/msm: Remove pm_runtime calls from msm_iommu.cJordan Crouse2019-04-181-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the IOMMU code calls pm_runtime_get/put on the GPU or display device before doing a IOMMU operation. This was because usually the IOMMU driver didn't do power control of its own and since the hardware used the same clocks and power as the respective multimedia device it was a easy way to make sure that the power was available. Now two things have changed. First, the SMMU devices can do their own power control and more important bringing up the a6xx GPU isn't as easy as turning on some clocks. To bring the GPU up we need the GMU which itself needs the IOMMU so we have a chicken and egg problem. Luckily this is easily fixed by removing the pm_runtime calls from the functions and letting the device link to the IOMMU device handle the magic.

| | | | | | | | | | | | | | | | | | | | | | | | | | The pages backing the GEM objects are kept pinned in place as long as they are alive, so they must not be allocated from the MOVABLE zone. Blocking page migration for too long will cause the VM subsystem headaches and will outright break CMA, as a few pinned pages in CMA will lead to failure to find the required large contiguous regions.

The interrupt chip builds upon a GIC SPI interrupt that raises high when any of the interrupts in the DPU's irq status register are triggered. From the kernel's perspective this is a chained irq chip, so requesting a flow handler for the GIC SPI and then calling generic IRQ handling code from that irq handler is not completely proper. It's better to convert this to a chained irq so that the GIC SPI irq doesn't appear in /proc/interrupts, can't have CPU affinity changed, and won't be accounted for with irq stats. Doing this also silences a recursive lockdep warning because we can specify a different lock class for the chained interrupts, silencing a warning that is easy to see with 'threadirqs' on the kernel commandline.

| | * | drm/msm: Fix A6XX support for opp-levelDouglas Anderson2019-01-291-1/+1

Thus the code in the GPU driver that was relying on the old bindings is now broken. Let's change the code to match the new bindings by adjusting the old string 'qcom,level' to the new string 'opp-level'. See the patch ("dt-bindings: opp: Introduce opp-level bindings"). NOTE: we will do additional cleanup to totally remove the string from the code and use the new dev_pm_opp_get_level() but we'll do it in a future patch. This will facilitate getting the important code fix in sooner without having to deal with cross-maintainer dependencies. This patch needs to land before the patch ("arm64: dts: sdm845: Add gpu and gmu device nodes") since if a tree contains the device tree patch but not this one you'll get a crash at bootup.
