The V3D engine has various hardware counters which might be interesting to userspace performance analysis tools. Expose new ioctls to create/destroy a performance monitor object and query the counter values of this perfmance monitor. Note that a perfomance monitor is given an ID that is only valid on the file descriptor it has been allocated from. A performance monitor can be attached to a CL submission and the driver will enable HW counters for this request and update the performance monitor values at the end of the job. Signed-off-by:

Hw older versions support non-alpha color formats derived from native alpha color formats only on the primary layer. For instance, RG16 native format without alpha works fine on 2nd layer but XR24 (derived color format from AR24) does not work on 2nd layer. Signed-off-by:

ltdc supports natively some color formats with alpha (like ARGB8888, ARGB1555, ARGB4444...). Related non-alpha formats are supported too (ARGB8888->XRGB8888, ARGB4444->XRGB4444...) by adjusting ltdc blending factors. Note: Wayland/Weston requests by default the non-alpha XRGB8888 color format. Signed-off-by:

The Versatile PL110 implementations use multiple endpoints: from the PL111 port, the lines are routed through a PLD, and from there forked so the same lines go to a VGA DAC and an external TFT panel connector. This is discrete wireing so there is no way to turn of one output, i.e. this is really two endpoints, not two ports. We model this with multiple endpoints, so we need to loop over the available endpoints, check for panel or bridge on each and accumulate the result before continuing. The code already will give the panel preference over the bridge, if present, so the output will be sent to the panel if both a panel and a bridge is present on two endpoints of the same port. If they all return -EPROBE_DEFER we return -EPROBE_DEFER as well. If just one endpoint is present on the port, the behaviour is the same as before. Reviewed-by:

The ARM Versatile series can do RGB/BGR565 with an external "PLD" (Programmable Logical Device). However the CLCD does not have control bits for this, so it needs to be set into the ordinary 16BPP mode, then the RGB/BGR565 handling of the pixel data is handled by configuring the PLD through the external register.

With a bit of refactoring we can contain the variant data for the strange PL110 versions that is feature-incomplete PL110 for the ARM Integrator/CP and somewhere inbetween PL110 and PL111 for the ARM Versatile AB and Versatile PB. We also accomodate for the custom duct-taped RGB565/BGR565 support in the Versatile variant. Reviewed-by:

The ARM reference designs "Versatile AB" and "Versatile PB" contain panel connectors with autodetection of the connected panel type. This adds a small driver utilizing the MFD syscon look-up to read the autodetection register and set up the corresponding panel appropriately. In the source file there is a bit of elaboration of the panel types and interfaces on these boards. This was tested with the PL111 DRM driver on the ARM Versatile AB with the IB2 daughterboard.

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Note that this replaces crtc_state->adjusted_mode usage with crtc_state->mode. The latter is the correct choice since that's the mode the user provided and it matches the plane crtc coordinates the user also provided. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state(). Cc: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by:

drm_encoder_slave is the old way to write bridge drivers, for i2c bridges only. It's deprecated, and definitely should not be used in new drivers. This has absolutely nothing to do with the new bridge driver infrastructure implemented by drm_bridge. What's even strange is that arcpgu doesn't even use any of this, it really only wants a plain normal drm_encoder. Nuke all the surplus real estate. v2: Actually git add after compile testing ... v3: Clarify commit message and stop including drm_encoder_slave.h.

During a non-blocking commit, it is possible to return before the commit_tail work is queued (-ERESTARTSYS, for example). Since a reference on the crtc commit object is obtained for the pending vblank event when preparing the commit, the above situation will leave us with an extra reference. Therefore, if the commit_tail worker has not consumed the event at the end of a commit, release it's reference. Changes since v1: - Also check for state->event->base.completion being set, to handle the case where stall_checks() fails in setup_crtc_commit(). Changes since v2: - Add a flag to drm_crtc_commit, to prevent dereferencing a freed event. i915 may unreference the state in a worker.

We never support certain mode flags etc. Reject those early on in the mode_config.mode_valid() hook. That allows us to remove some duplicated checks from the connector .mode_valid() hooks, and it guarantees that we never see those flags even from user mode as the mode_config.mode_valid() hooks gets executed for those as well.

Allow drivers to provide a device wide .mode_valid() hook in addition to the already existing crtc/encoder/bridge/connector hooks. This can be used to validate device/driver wide constraings without having to add those to the other hooks. And since we call this hook also for user modes later on in the modeset we don't have to worry about anything the hook has already rejected. I also have some further ideas for this hook. Eg. we could replace the drm_mode_set_crtcinfo(HALVE_V) call in drm_mode_convert_umode()/etc. with a driver specific variant via this hook. At least on i915 we would like to pass CRTC_STEREO_DOUBLE to that function instead, and then we could safely use the crtc_ timings in all our .mode_valid() hooks, which would allow us to reuse those hooks for validating the adjusted_mode during a modeset. v2: Fix the language fails in the kernel docs (Daniel) Signed-off-by:

Reject any mode with DRM_MODE_FLAG_BCAST. We have no code that even checks for this flag hence it can't possibly do any good. I think this maybe originated from fbdev where it was supposed to indicate PAL/NTSC broadcast timings. I have no idea why those would have to be identified by a flag rather than by just the timings themselves. And then I assume it got copied into xfree86 for fbdevhw, and later on it leaked into the randr protocol and kms uapi. Since kms fbdev emulation never uses the corresponding fbdev flag there should be no sane way for this to come back into kms via userspace either.
