2018-07-05drm/v3d: Remove unnecessary dma_fence_ops.Eric Anholt1-12/+0
The dma-fence core as of commit 418cc6ca0607 ("dma-fence: Make ->wait callback optional") provides appropriate defaults for these methods.

2018-07-05drm/v3d: Delay the scheduler timeout if we're still making progress.Eric Anholt3-0/+21
GTF-GLES2.gtf.GL.acos.acos_float_vert_xvary submits jobs that take 4 seconds at maximum resolution, but we still want to reset quickly if a job is really hung. Sample the CL's current address and the return address (since we call into tile lists repeatedly) and if either has changed then assume we've made progress.

2018-07-05drm/v3d: use new return type vm_fault_t in v3d_gem_faultSouptick Joarder2-24/+7
Instead of converting an errno into a vm_fault_t ourselves, use vmf_insert_mixed() which returns a vm_fault_t directly.

2018-06-21drm/v3d: Remove the bad signaled() implementation.Eric Anholt4-18/+6
Since our seqno value comes from a counter associated with the GPU ring, not the entity (aka client), they'll be completed out of order. There's actually no need for this code at all, since we don't have enable_signaling() and thus DMA_FENCE_SIGNALED_BIT will be set before we could be called.

2018-06-21drm/v3d: Take a lock across GPU scheduler job creation and queuing.Eric Anholt2-0/+9
Between creation and queueing of a job, you need to prevent any other job from being created and queued. Otherwise the scheduler's fences may be signaled out of seqno order. v2: move mutex unlock to the error label.

2018-06-20Merge drm-upstream/drm-next into drm-misc-nextGustavo Padovan2-1/+2
We got a few conflicts in drm_atomic.c after merging the DRM writeback support, now we need a backmerge to unlock develop development on drm-misc-next. Signed-off-by: Gustavo Padovan <[email protected]>

Without CONFIG_MMU, we get a link error: drivers/gpu/drm/v3d/v3d_bo.o: In function `v3d_gem_fault': v3d_bo.c:(.text+0x3ca): undefined reference to `vm_insert_mixed' The other drivers with this problem already depend on CONFIG_MMU, so let's do the same thing here.

into drm-next Main changes for 4.18. I'd like to do a separate pull for vega20 later this week or next. Highlights: - Reserve pre-OS scanout buffer during init for seemless transition from console to driver - VEGAM support - Improved GPU scheduler documentation - Initial gfxoff support for raven - SR-IOV fixes - Default to non-AGP on PowerPC for radeon - Fine grained clock voltage control for vega10 - Power profiles for vega10 - Further clean up of powerplay/driver interface - Underlay fixes - Display link bw updates - Gamma fixes - Scatter/Gather display support on CZ/ST - Misc bug fixes and clean ups [airlied: fixup v3d vs scheduler API change] Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Dave Airlie <[email protected]>
2018-05-03drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+Eric Anholt14-0/+2940
This driver will be used to support Mesa on the Broadcom 7268 and 7278 platforms. V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.
