It includes code cleanups from Bhumika and Liviu, a significant shader performance fix and additions to the cmdstream validator from Wladimir and the addition of a cmdbuf suballocator by myself. The suballocator improves performance on all chips by reducing the CPU overhead of the kernel driver and side steps the GC3000 FE MMU flush erratum, now making the workarounds in IOVA allocation we had before unnecessary, which results in a nice cleanup of the code in that area. * 'drm-etnaviv-next' of https://git.pengutronix.de/git/lst/linux: drm/etnaviv: Remove duplicate header file include Revert "drm/etnaviv: trick drm_mm into giving out a low IOVA" drm/etnaviv: add cmdbuf suballocator drm/etnaviv: get cmdbuf physical address through the cmdbuf abstraction drm/etnaviv: wire up iova handling in new cmdbuf abstraction drm/etnaviv: move cmdbuf de-/allocation into own file drm/etnaviv: always flush MMU TLBs on map/unmap drm/etnaviv: constify etnaviv_iommu_ops structures drm/etnaviv: set up initial PULSE_EATER register drm/etnaviv: add new GC3000 sensitive states

Commit be7f735cd5ea ("drm: Rely on mode_config data for fb_helper initialization") broke the build when CONFIG_DRM_FBDEV_EMULATION is disabled because it didn't update the prototype for drm_fb_helper_init in that case.

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

Some state is coupled into the device lifetime outside of the load/unload timeframe and requires teardown during final unreference from drm_dev_release(). For example, dmabufs hold both a device and module reference and may live longer than expected (i.e. the current pattern of the driver tearing down its state and then releasing a reference to the drm device) and yet touch driver private state when destroyed. v2: Export drm_dev_fini() and move the responsibility for finalizing the drm_device and freeing it to the release callback. (If no callback is provided, the core will call drm_dev_fini() and kfree(dev) as before.) v3: Remember to add drm_dev_fini() to drm_drv.h v4: Tidy language for kerneldoc v5: Cross reference from drm_dev_init() to note that driver->release() allows for arbitrary embedding. v6: Refer to driver data rather than driver state, as state is now becoming associated with the struct drm_atomic_state and friends.

MHL3 protocol requires registry adjustments depending on chosen video mode. Necessary information is gathered in mode_fixup callback. In case of HDMI video modes driver should also send special AVI and MHL3 infoframes.

Now that commandstreams are handled through the cmdbuf suballocator the workaround to make the IOVA games work is not needed anymore. Signed-off-by:

There are 3 big benefits to suballocating a single big DMA buffer for command submission: 1. Avoid hammering CMA. The old way of allocating and freeing a DMA buffer for each submission was hitting some of the real slow pathes in CMA, as this allocator was not designed for a concurrent small buffers load. 2. Less TLB flushes on IOMMUv2. If a new command buffer is mapped into the GPU address space the MMU TLBs need to be flushed. By having one big buffer statically mapped to the GPU, a lot of those flushes can be avoided. 3. No funky workarounds for GC3000. The FE TLB flush on GC3000 isn't reliable. To work around that we tried to lay out the cmdbufs in the GPU address space in a way to avoid this issue. This hasn't always worked if the address space is crowded. A single statically mapped buffer avoids the erratum completely. Signed-off-by:

This ensures that the GPU isn't able to write into already freed objects, as doing this in the IOVA reaper isn't enough, as the gem_free_object path will also cause unmaps to happen. On MMUv2 this also ensures that stale entries, which may have been prefetched into the TLB will be purged. The flush is low overhead, as it gets batched up with the next user command buffer, so this isn't incuring an overhead for each buffer map/unmap. Signed-off-by:

Declare etnaviv_iommu_ops structure as const as it is only used when the reference of one of its field is stored in the ops field of a iommu_domain structure. This ops field is of type const, so etnaviv_iommu_ops structures having similar properties can be declared const too. Done using Coccinelle. Before and after size details of .o file remains the same after cross compiling for arm architecture. lst: Trimmed commit message, apply the same change to iommu_v2. Signed-off-by:
