https://gitlab.freedesktop.org/drm/msm into drm-fixes A few fixes, mostly fallout from the address space refactor and dpu color processing.

2020-06-22drm/msm: Fix up the rest of the messed up address sizesJordan Crouse5-5/+5
msm_gem_address_space_create() changed to take a start/length instead of a start/end for the iova space but all of the callers were just cut and pasted from the old usage. Most of the mistakes have been fixed up so just catch up the rest.

2020-06-18drm/msm: Fix address space size after refactor.Eric Anholt1-1/+1
Previously the address space went from 16M to ~0u, but with the refactor one of the 'f's was dropped, limiting us to 256MB. Additionally, the new interface takes a start and size, not start and end, so we can't just copy and paste.

2020-06-13drm/msm: Fix 0xfffflub in "Refactor address space initialization"John Stultz1-1/+1
This week I started seeing GPU crashes on my DragonBoard 845c which I narrowed down to being caused by commit ccac7ce373c1 ("drm/msm: Refactor address space initialization"). Looking through the patch, Jordan and I couldn't find anything obviously wrong, so I ended up breaking that change up into a number of smaller logical steps so I could figure out which part was causing the trouble. Ends up, visually counting 'f's is hard, esp across a number of lines: 0xfffffff != 0xffffffff This patch corrects the end value we pass in to msm_gem_address_space_create() in adreno_iommu_create_address_space() so that it matches the value used before the problematic patch landed. With this change, I no longer see the GPU crashes that were affecting me.

2020-05-23drm/msm: Refactor address space initializationJordan Crouse17-118/+85
Refactor how address space initialization works. Instead of having the address space function create the MMU object (and thus require separate but equal functions for gpummu and iommu) use a single function and pass the MMU struct in. Make the generic code cleaner by using target specific functions to create the address space so a2xx can do its own thing in its own space. For all the other targets use a generic helper to initialize IOMMU but leave the door open for newer targets to use customization if they need it.

2020-05-23drm/msm: Attach the IOMMU device during initializationJordan Crouse9-55/+27
Everywhere an IOMMU object is created by msm_gpu_create_address_space the IOMMU device is attached immediately after. Instead of carrying around the infrastructure to do the attach from the device specific code do it directly in the msm_iommu_init() function. This gets it out of the way for more aggressive cleanups that follow.

2020-05-18drm/msm: Add syncobj support.Bas Nieuwenhuizen2-3/+235
This 1) Enables core DRM syncobj support. 2) Adds options to the submission ioctl to wait/signal syncobjs. Just like the wait fence fd, this does inline waits. Using the scheduler would be nice but I believe it is out of scope for this work. Support for timeline syncobjs is implemented and the interface is ready for it, but I'm not enabling it yet until there is some code for turnip to use it. The reset is mostly in there because in the presence of waiting and signalling the same semaphores, resetting them after signalling can become very annoying. v2: - Fixed style issues - Removed a cleanup issue in a failure case - Moved to a copy_from_user per syncobj v3: - Fixed a missing declaration introduced in v2 - Reworked to use ERR_PTR/PTR_ERR - Simplified failure gotos.

2020-05-18drm/msm/mdp5: Add MDP5 configuration for MSM8x36.Konrad Dybcio1-0/+76
This change adds MDP5 configuration for MSM8x36-based SoCs, like MSM8936, 8939 and their APQ variants. The configuration is based on MSM8916's, but adds some notable features, like ad and pp blocks, along with some register changes. changes since v1: - add an ad block - add a second mixer @ 0x47000 - adjust .max_width - write a more descriptive commit message Signed-off-by: Konrad Dybcio <konradybcio@gmail.com> Reviewed-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

https://gitlab.freedesktop.org/drm/msm into drm-next A bit smaller this time around.. there are still a couple uabi additions for vulkan waiting in the wings, but I punted on them this cycle due to running low on time. (They should be easy enough to rebase, and if it is a problem for anyone I can push a next+uabi branch so that tu work can proceed.) The bigger change is refactoring dpu resource manager and moving dpu to use atomic global state. Other than that, it is mostly cleanups and fixes.

2020-03-20drm/msm/a6xx: Use the DMA API for GMU memory objectsJordan Crouse2-107/+14
The GMU has very few memory allocations and uses a flat memory space so there is no good reason to go out of our way to bypass the DMA APIs which were basically designed for this exact scenario. v7: Check return value of dma_set_mask_and_coherent v4: Use dma_alloc_wc() v3: Set the dma mask correctly and use dma_addr_t for the iova type v2: Pass force_dma false to of_dma_configure to require that the DMA region be set up and return error from of_dma_configure to fail probe.

2020-03-19drm/msm/a5xx: Always set an OPP supported hardware valueJordan Crouse1-7/+20
If the opp table specifies opp-supported-hw as a property but the driver has not set a supported hardware value the OPP subsystem will reject all the table entries. Set a "default" value that will match the default table entries but not conflict with any possible real bin values. Also fix a small memory leak and free the buffer allocated by nvmem_cell_read().
