drm/v3d: Take a lock across GPU scheduler job creation and queuing.

2018-10-03T23:59:14+00:00

[ Upstream commit 7122b68b8a9692dcc3acf89595f04c492872115f ] 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.

drm/v3d: add CONFIG_MMU dependency

2018-05-30T19:15:18+00:00

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.

Merge branch 'drm-next-4.18' of git://people.freedesktop.org/~agd5f/linux into drm-next

2018-05-15T22:31:29+00:00

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/20180515185450.1113-1-alexander.deucher@amd.com Signed-off-by: Dave Airlie

drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+

2018-05-03T23:26:30+00:00

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.
