Add a convenience macro for iterating connector->encoder_ids[]. Isolates the users from the implementation details. Note that we don't seem to pass the file_priv down to drm_encoder_find() because encoders apparently don't get leased. No idea why drm_encoder_finc() even takes the file_priv actually. Also use ARRAY_SIZE() when populating the array to avoid spreading knowledge about the array size all over. v2: Hide the drm_encoder_find() in the macro, and rename the macro appropriately (Daniel) v3: Fix kernel docs (Daniel) Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by:Daniel Vetter <daniel.vetter@ffwll.ch>

Instead of using the .best_encoder() hook to figure out whether a given connector+crtc combo will work, let's instead do what userspace does and just iterate over all the encoders for the connector, and then check each crtc against each encoder's possible_crtcs bitmask. v2: Avoid oopsing on NULL encoders (Daniel) s/connector_crtc_ok/connector_has_possible_crtc/ Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: -

This commit adds the essential infrastructure for around CRTCs which is composed of: a new data struct for output data information, a function for creating planes, and a simple encoder attached to the connector. Finally, due to the introduction of a new initialization function, connectors were moved from vkms_drv.c to vkms_display.c. Signed-off-by:

Haneen Mohammed authored
This patch introduces Virtual Kernel Mode-Setting (VKMS) driver. It creates a very basic kms driver with 1 crtc/encoder/connector/plane. VKMS driver would be useful for testing, or for running X (or similar) on headless machines and be able to still use the GPU. Thus it enables a virtual display without the need for hardware display capability. Signed-off-by:

In the quest to remove all stack VLA usage from the kernel[1], this switches to using a kmalloc allocation and moves all the size calculations to the start to do an allocation. If an upper bounds on the mode timing calculations could be determined, a fixed stack size could be used instead.

In commits: 34a2ab5e ("drm: Add acquire ctx parameter to ->update_plane") 19315294 ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

When this was introduced in commit a519435a Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction. Reviewed-by:

Many drivers have a trivial implementation for ->enable_signaling. Let's make it optional by assuming that signalling is already available when the callback isn't present. v2: Don't do the trick to set the ENABLE_SIGNAL_BIT unconditionally, it results in an expensive spinlock take for everyone. Instead just check if the callback is present. Suggested by Maarten. Also move misplaced kerneldoc hunk to the right patch.

The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).

This allows panels or bridges that need to send DSI commands during pre_enable() to successfully send them. We delay DISP0 (aka the actual display) enabling until after pre_enable so that pixels aren't streaming before then. v2: Just clear out the encoder->bridge value to disable the midlayer calls (idea by Andrzej Hajda).
