Ie. vblank irq would trigger event and userspace could begin the next atomic update, before the commit worker had a chance to clear the pending flag. If we do end up needing something to prevent userspace from trying another pageflip before getting vblank event, it should probably be implemented as a pending_planes bitmask, similar to pending_crtcs. See start_atomic() and end_atomic().

I've been working through deqp, and I've got a couple more things to fix (but we've gone from 70% to 80+% pass in last day, and current deqp run that is going should pick up another 5-10%). I expect to push the mesa patches today or tomorrow. There are a couple more a5xx related patches to take the gpu out of secure mode (for the devices that come up in secure mode, like the hw I have), but those depend on an scm patch that would come in through another tree. If that can land in the next day or two, there might be a second late pull request for drm/msm. In addition to the new-shiny, there have also been a lot of overlay/ plane related fixes for issues found using drm-hwc2 (in the process of testing/debugging the atomic/kms fence patches), resulting in rework to assign hwpipes to kms planes dynamically (as part of global atomic state) and also handling SMP (fifo) block allocation atomically as part of the ->atomic_check() step. All those patches should also help out atomic weston (when those patches eventually land). * 'msm-next' of git://people.freedesktop.org/~robclark/linux: (36 commits) drm/msm: gpu: Add support for the GPMU drm/msm: gpu: Add A5XX target support drm/msm: Disable interrupts during init drm/msm: Remove 'src_clk' from adreno configuration drm/msm: gpu: Add OUT_TYPE4 and OUT_TYPE7 drm/msm: Add adreno_gpu_write64() drm/msm: gpu Add new gpu register read/write functions drm/msm: gpu: Return error on hw_init failure drm/msm: gpu: Cut down the list of "generic" registers to the ones we use drm/msm: update generated headers drm/msm/adreno: move scratch register dumping to per-gen code drm/msm/rd: support for 64b iova drm/msm: convert iova to 64b drm/msm: set dma_mask properly drm/msm: Remove bad calls to of_node_put() drm/msm/mdp5: move LM bounds check into plane->atomic_check() drm/msm/mdp5: dump smp state on errors too drm/msm/mdp5: add debugfs to show smp block status drm/msm/mdp5: handle SMP block allocations "atomically" drm/msm/mdp5: dynamically assign hw pipes to planes ... 2016-11-30T04:28:20+00:00 Dave Airlie airlied@redhat.com 2016-11-30T04:28:20+00:00 urn:sha1:a90f58311f48f510ea63cd2db2e32f74712c43f3 Big thing is that drm-misc is now officially a group maintainer/committer model thing, with MAINTAINERS suitably updated.

On the display side, iova is still 32b so it can ignore the upper bits. (Although all the armv8 devices have an iommu that can map 64b pa to 32b iova.)

It is legal, and in fact common, to create a larger fb, only only scan-out a smaller part of it. For example multi-monitor configurations for x11, or android wallpaper layer (which is created larger than the screen resolution for fast scrolling by just changing the src x/y coordinates).

Re-work the block allocation to request blocks during atomic_check(), but not update the hw until committing the atomic update. Since SMP blocks allocated at atomic_check() time, we need to manage the SMP state as part of mdp5_state (global atomic state). This actually ends up significantly simplifying the SMP management, as the SMP module does not need to manage the intermediate state between assigning new blocks before setting flush bits and releasing old blocks after vblank. (The SMP registers and SMP allocation is not double-buffered, so newly allocated blocks need to be updated in kms->prepare_commit() released blocks in kms->complete_commit().)
