into drm-next 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

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi
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.

vram_size is supposed to be the total amount of VRAM that can be used by userspace, which corresponds to the TTM VRAM manager size (which is normally the full amount of VRAM, but can be just the visible VRAM when DMA can't be used for BO migration for some reason). The above was incorrectly used for vram_visible before, resulting in generally too large values being reported.

2017-02-02drm: Provide a driver hook for drm_dev_release()Chris Wilson
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.

Commit 21e6d8428664 ("perf diff: Use perf_hpp__register_sort_field interface") changed list_add() to perf_hpp__register_sort_field(). This resulted in a behavior change since the field was added to the tail instead of the head. So the -o option is mostly ignored due to its order in the list.

2017-02-02perf diff: Fix segfault on 'perf diff -o N' optionNamhyung Kim
The -o/--order option is to select column number to sort a diff result. It does the job by adding a hpp field at the beginning of the sort list. But it should not be added to the output field list as it has no callbacks required by a output field. During the setup_sorting(), the perf_hpp__setup_output_field() appends the given sort keys to the output field if it's not there already. Originally it was checked by fmt->list being non-empty. But commit 3f931f2c4274 ("perf hists: Make hpp setup function generic") changed it to check the ->equal callback. Anyways, we don't need to add the pseudo hpp field to the output field list since it won't be used for output. So just skip fields if they have no ->color or ->entry callbacks.

Now that commandstreams are handled through the cmdbuf suballocator the workaround to make the IOVA games work is not needed anymore. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2017-02-02drm/etnaviv: add cmdbuf suballocatorLucas Stach
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: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>
