2021-01-06drm/cirrus: Remove references to struct drm_device.pdevThomas Zimmermann1-1/+0
Using struct drm_device.pdev is deprecated. Convert cirrus to struct drm_device.dev. No functional changes.

2020-11-09drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backendsThomas Zimmermann2-8/+12
This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian) * fix a trailing { in drm_gem_vmap() * remove several empty functions instead of converting them (Daniel) * comment uses of raw pointers with a TODO (Daniel) * TODO list: convert more helpers to use struct dma_buf_map Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Christian König <christian.koenig@amd.com> Tested-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-7-tzimmermann@suse.de

2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter10-10/+10
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch
2020-06-24drm/mipi-dbi: Remove ->enabledDaniel Vetter2-17/+6
The atomic helpers try really hard to not lose track of things, duplicating enabled tracking in the driver is at best confusing. Double-enabling or disabling is a bug in atomic helpers. In the fb_dirty function we can just assume that the fb always exists, simple display pipe helpers guarantee that the crtc is only enabled together with the output, so we always have a primary plane around. Now in the update function we need to be a notch more careful, since that can also get called when the crtc is off. And we don't want to upload frames when that's the case, so filter that out too.

2020-03-26drm/gm12u320: Simplify upload workDaniel Vetter1-103/+68
Instead of having a work item that never stops (which really should be a kthread), with a dedicated workqueue to not upset anyone else, use a delayed work. A bunch of changes: - We can throw out all the custom wakeup and requeue logic and state tracking. If we schedule the work with a 0 delay it'll get scheduled immediately. - Persistent state (frame & draw_status_timeout) need to be moved out of the work. - diff is bigger than the changes, biggest chunk is reindenting the work fn because it lost its while loop. Lots of code deleting as consequence all over. Specifically we can delete the drm_driver.release code now! v2: Review from Hans: - Use mod_delayed_work in the plane update path to make sure we do actually schedule immediately). In the worker we still want queue_delayed_work, which won't modify the timeout when the work is already scheduled. Which is exactly what we want if the work races with a plane update. - Switch to system_long_wq, Hans says on usb2 a plane upload can take 80 ms.

Add support for the Okaya RH128128T display to the st7735r driver on DT-enabled systems. The RH128128T is a 128x128 1.44" TFT display driven by a Sitronix ST7715R TFT Controller/Driver. The latter is very similar to the ST7735R, and can be handled by the existing st7735r driver.

2020-01-19drm: tiny: st7735r: Prepare for adding support for more displaysGeert Uytterhoeven1-14/+53
Currently the st7735r driver supports only a single display panel. Prepare for adding support for other display panels by factoring out the display-specific parameters in struct st7735r_cfg. For now, the following parameters can be configured: - Display resolution, - Horizontal/vertical display offsets, - Read-write versus read-only controllers, - RGB versus BGR color component ordering. Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really specific to the Jianda JD-T18003-T01 display anymore.

2019-10-01drm/tiny: Kconfig: Remove always-y THERMAL dep. from TINYDRM_REPAPERUlf Magnusson1-1/+0
Commit 554b3529fe01 ("thermal/drivers/core: Remove the module Kconfig's option") changed the type of THERMAL from tristate to bool, so THERMAL || !THERMAL is now always y. Remove the redundant dependency. Discovered through Kconfiglib detecting a dependency loop. The C tools simplify the expression to y before running dependency loop detection, and so don't see it. Changing the type of THERMAL back to tristate makes the C tools detect the same loop. Not sure if running dep. loop detection after simplification can be called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at least.

2019-08-12drm: gm12u320: Do not take a mutex from a wait_event conditionHans de Goede1-12/+2
I made the condition of the wait_event_timeout call in gm12u320_fb_update_work a helper which takes a mutex to make sure that any writes to fb_update.run or fb_update.fb from other CPU cores are seen before the check is done. This is not necessary as the wait_event helpers contain the necessary barriers for this themselves. More over it is harmfull since by the time the check is done the task is no longer in the TASK_RUNNING state and calling mutex_lock while not in task-running is not allowed, leading to this warning when the kernel is build with some extra locking checks enabled: [11947.450011] do not call blocking ops when !TASK_RUNNING; state=2 set at [<00000000e4306de6>] prepare_to_wait_event+0x61/0x190 This commit fixes this by dropping the helper and simply directly checking the condition (without unnecessary locking) in the wait_event_timeout call.
