2020-11-16drm: fix some kernel-doc markupsMauro Carvalho Chehab15-19/+22
Some identifiers have different names between their prototypes and the kernel-doc markup. Others need to be fixed, as kernel-doc markups should use this format: identifier - description Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Acked-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/12d4ca26f6843618200529ce5445063734d38c04.1605521731.git.mchehab+huawei@kernel.org
2020-11-16drm/panfrost: Move the GPU reset bits outside the timeout handlerBoris Brezillon3-64/+130
We've fixed many races in panfrost_job_timedout() but some remain. Instead of trying to fix it again, let's simplify the logic and move the reset bits to a separate work scheduled when one of the queue reports a timeout. v5: - Simplify panfrost_scheduler_stop() (Steven Price) - Always restart the queue in panfrost_scheduler_start() even if the status is corrupted (Steven Price) v4: - Rework the logic to prevent a race between drm_sched_start() (reset work) and drm_sched_job_timedout() (timeout work) - Drop Steven's R-b - Add dma_fence annotation to the panfrost_reset() function (Daniel Vetter) v3: - Replace the atomic_cmpxchg() by an atomic_xchg() (Robin Murphy) - Add Steven's R-b v2: - Use atomic_cmpxchg() to conditionally schedule the reset work (Steven Price) Fixes: 1a11a88cfd9a ("drm/panfrost: Fix job timeout handling") Cc: <stable@vger.kernel.org> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Signed-off-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201105151704.2010667-1-boris.brezillon@collabora.com

2020-11-16drm/panel: s6e63m0: Set up some display infoLinus Walleij1-0/+9
Copy over the width/height in millimeters to the (somewhat redundant) display info, and set up the bus format and bus flags for the display. When used as DPI this display requires DE to be active low and pixel data to be output on the negative edge. It might be that it was previously used with a display controller that either does not support these settings or was hardcoded to use these as default. This information comes from the source code of the Samsung GT-I9070 mobile phone.

2020-11-11drm/ingenic: ipu: Search for scaling coefs up to 102% of the screenPaul Cercueil1-8/+15
Increase the scaled image's theorical width/height until we find a configuration that has valid scaling coefficients, up to 102% of the screen's resolution. This makes sure that we can scale from almost every resolution possible at the cost of a very small distorsion. The CRTC_W / CRTC_H are not modified. This algorithm was already in place but would not try to go above the screen's resolution, and as a result would only work if the CRTC_W / CRTC_H were smaller than the screen resolution. It will now try until it reaches 102% of the screen's resolution. Note that this algorithm exists mostly as a band-aid for a missing functionality: it is not possible for userspace to request the closest mode that would encapsulate the provided one, because the GEM buffer is created beforehand. If there was a way to let the kernel tweak the mode, I could write a better algorithm that would result in a better looking picture.

2020-11-11drm/ttm: add multihop infrastrucutre (v3)Dave Airlie7-15/+77
Currently drivers get called to move a buffer, but if they have to move it temporarily through another space (SYSTEM->VRAM via TT) then they can end up with a lot of ttm->driver->ttm call stacks, if the temprorary space moves requires eviction. Instead of letting the driver do all the placement/space for the temporary, allow it to report back (-EMULTIHOP) and a placement (hop) to the move code, which will then do the temporary move, and the correct placement move afterwards. This removes a lot of code from drivers, at the expense of adding some midlayering. I've some further ideas on how to turn it inside out, but I think this is a good solution to the call stack problems. v2: separate out the driver patches, add WARN for getting MULTHOP in paths we shouldn't (Daniel) v3: use memset (Christian) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: hristian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201109005432.861936-2-airlied@gmail.com

The Intel Keem Bay display controller is only present on Intel Keem Bay SoCs. Hence add a dependency on ARCH_KEEMBAY, to prevent asking the user about this driver when configuring a kernel without Intel Keem Bay platform support. Note that: 1. The dependency on ARM is dropped, as Keem Bay SoCs are only supported in arm64 kernel builds, 2. The dependencies on OF and COMMON_CLK can be dropped for compile-testing, as the driver builds fine regardless.
