2020-06-03drm/msm: Don't call dma_buf_vunmap without _vmapDaniel Vetter1-2/+4
I honestly don't exactly understand what's going on here, but the current code is wrong for sure: It calls dma_buf_vunmap without ever calling dma_buf_vmap. What I'm not sure about is whether the WARN_ON is correct: - msm imports dma-buf using drm_prime_sg_to_page_addr_arrays. Which is a pretty neat layering violation of how you shouldn't peek behind the curtain of the dma-buf exporter, but par for course. Note that all the nice new helpers don't (and we should probably have a bit a warning about this in the kerneldoc). - but then in the get_vaddr() in msm_gem.c, we seems to happily wrap a vmap() around any object with ->pages set (so including imported dma-buf). - I'm not seeing any guarantees that userspace can't use an imported dma-buf for e.g. MSM_SUBMIT_CMD_BUF in a5xx_submit_in_rb, so no guarantees that an imported dma-buf won't end up with a ->vaddr set. But even if that WARN_ON is wrong, cleaning up a vmap() done by msm by calling dma_buf_vunmap is the wrong thing to do. v2: Rob said in review that we do indeed have a gap in get_vaddr() that needs to be plugged. But the users I've found aren't legit users on imported dma-buf, so we can just reject that.

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.

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.

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().
