eb8d395f - drm/v3d: Introduce gemfs

Mon, 23 Sep 2024 13:55:09 +0000

drm/v3d: Introduce gemfsCreate a separate "tmpfs" kernel mount for V3D. This will allow us tomove away from the shmemfs `shm_mnt` and gives the flexibility to dothings like set our own mount options. Here, the interest is to use"huge=", which should allow us to enable the use of THP for ourshmem-backed objects.Signed-off-by: Maíra Canal Reviewed-by: Iago Toral Quiroga Link: https://patchwork.freedesktop.org/patch/msgid/20240923141348.2422499-6-mcanal@igalia.com List of files: /linux-6.15/drivers/gpu/drm/v3d/Makefile

9032d5f6 - drm/v3d: Detach job submissions IOCTLs to a new specific file

Thu, 30 Nov 2023 16:40:26 +0000

drm/v3d: Detach job submissions IOCTLs to a new specific fileWe will include a new job submission type, the CPU job submission. Forreadability and maintability, separate the job submission IOCTLs andrelated operations from v3d_gem.c.Minor fix in the CSD submission kernel doc:CSD (texture formatting) -> CSD (compute shader).Signed-off-by: Melissa Wen Signed-off-by: Maíra Canal Reviewed-by: Iago Toral Quiroga Link: https://patchwork.freedesktop.org/patch/msgid/20231130164420.932823-5-mcanal@igalia.com List of files: /linux-6.15/drivers/gpu/drm/v3d/Makefile

509433d8 - drm/v3d: Expose the total GPU usage stats on sysfs

Tue, 05 Sep 2023 21:06:35 +0000

drm/v3d: Expose the total GPU usage stats on sysfsThe previous patch exposed the accumulated amount of active time perclient for each V3D queue. But this doesn't provide a global notion ofthe GPU usage.Therefore, provide the accumulated amount of active time for each V3Dqueue (BIN, RENDER, CSD, TFU and CACHE_CLEAN), considering all the jobssubmitted to the queue, independent of the client.This data is exposed through the sysfs interface, so that if theinterface is queried at two different points of time the usage percentageof each of the queues can be calculated.Co-developed-by: Jose Maria Casanova Crespo Signed-off-by: Jose Maria Casanova Crespo Signed-off-by: Maíra Canal Acked-by: Jose Maria Casanova Crespo Reviewed-by: Melissa Wen Link: https://patchwork.freedesktop.org/patch/msgid/20230905213416.1290219-3-mcanal@igalia.com List of files: /linux-6.15/drivers/gpu/drm/v3d/Makefile

26a4dc29 - drm/v3d: Expose performance counters to userspace

Tue, 08 Jun 2021 11:15:41 +0000

drm/v3d: Expose performance counters to userspaceThe V3D engine has several hardware performance counters that can ofinterest for userspace performance analysis tools.This exposes new ioctls to create and destroy performance monitorobjects, as well as to query the counter values.Each created performance monitor object has an ID that can be attachedto CL/CSD submissions, so the driver enables the requested counters whenthe job is submitted, and updates the performance monitor values whenthe job is done.It is up to the user to ensure all the jobs have been finished beforegetting the performance monitor values. It is also up to the user toproperly synchronize BCL jobs when submitting jobs with differentperformance monitors attached.Cc: Daniel Vetter Cc: David Airlie Cc: Emma Anholt To: dri-devel@lists.freedesktop.orgSigned-off-by: Juan A.

57692c94 - drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+

Mon, 30 Apr 2018 18:10:58 +0000

drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+This driver will be used to support Mesa on the Broadcom 7268 and 7278platforms.V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4'scomplicated CL/shader validation scheme. This massively changes theGEM 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 changesv4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.Signed-off-by: Eric Anholt Acked-by: Daniel Vetter (v4)Acked-by: Dave Airlie (v3, requested submit_cl change)Link: https://patchwork.freedesktop.org/patch/msgid/20180430181058.30181-3-eric@anholt.net List of files: /linux-6.15/drivers/gpu/drm/v3d/Makefile
