2025-03-07drm/vkms: Allow to attach planes and CRTCsJosé Expósito
Add a list of possible CRTCs to the plane configuration and helpers to attach, detach and get the primary and cursor planes attached to a CRTC. Now that the default configuration has its planes and CRTC correctly attached, configure the output following the configuration.

2024-11-22drm/vkms: Remove index parameter from init_vkms_outputLouis Chauvet
VKMS currently supports only one CRTC, so it make no sense to have this index configurable. To avoid issues, replace this hardcoded index by drm_crtc_mask when applicable. There is no need to manually set a crtc mask on primary and cursor plane as it is automatically set by drmm_crtc_alloc_with_planes. In addition, this will remove the use of an uninitialized structure in vkms_add_overlay_plane. This currently works by chance because two things: - vkms_plane_init always set a possible_crtcs value, so the problematic branch is never used; - drm_crtc_mask on an kzalloc'd drm_crtc returns BIT(0), and the VKMS CRTC always have this id.

2020-12-11drm/vkms: Unset preferred_depthDaniel Vetter
There's a confusion between the preferred_depth uapi and the generic fbdev helpers. Former wants depth, latter wants bpp, and for XRGB8888 they don't match. Which hit me with vkms, which wants that. All other drivers setting this and using the generic fbdev helpers use 16, where both numbers match, for RGB565. Since fixing this is a bit involved (I think for atomic drivers we should just compute this all internally from the format list of the first primary plane) paper over the issue in vkms by using defaults everywhere. Then userspace will pick XRGB8888, and fbdev helpers will do the same, and we have what we want.

2020-09-11drm/vkms: Use devm_drm_dev_allocDaniel Vetter
This means we also need to slightly restructure the exit code, so that final cleanup of the drm_device is triggered by unregistering the platform device. Note that devres is both clean up when the driver is unbound (not the case for vkms, we don't bind), and also when unregistering the device (very much the case for vkms). Therefore we can rely on devres even though vkms isn't a proper platform device driver. This also somewhat untangles the load code, since the drm and platform device setup are no longer interleaved, but two distinct steps. v2: use devres_open/release_group so we can use devm without real hacks in the driver core or having to create an entire fake bus for testing drivers. Might want to extract this into helpers eventually, maybe as a mock_drm_dev_alloc or test_drm_dev_alloc. v3: Only deref vkms_device after checking it (Melissa) Reviewed-by: Melissa Wen <melissa.srw@gmail.com> Cc: Melissa Wen <melissa.srw@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> Cc: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200909091833.440548-1-daniel.vetter@ffwll.ch

2019-07-12drm/vkms: Avoid assigning 0 for possible_crtcRodrigo Siqueira
When vkms invoke drm_universal_plane_init(), it sets 0 for possible_crtcs parameter which means that planes can't be attached to any CRTC. It currently works due to some safeguard in the drm_crtc file; however, it is possible to identify the problem by trying to append a second connector. This patch fixes this issue by modifying vkms_plane_init() to accept an index parameter which makes the code a little bit more flexible and avoid set zero to possible_crtcs.

2019-06-26drm/vkms: flush crc workers earlier in commit flowDaniel Vetter
Currently, we flush pending CRC workers very late in the commit flow, when we destroy all the old crtc states. Unfortunately, at that point, the framebuffers are already unpinned (and our vaddr possible gone), so this isn't good. Also, the plane_states we need might also already be cleaned up, since cleanup order of state structures isn't well defined. Fix this by waiting for all CRC workers of the old state to complete before we start any of the cleanup work. For correct ordering and avoiding races, we can only flush_work after drm_atomic_helper_wait_for_vblanks() since we know that all subsequent queue_work will be for the new state. Only once that's done is flush_work() useful, before that we might flush the work, and then right after the hrtimer that simulates vblank queues it again. Every time you have a flush_work before cleaning up the work structure, the following sequence must be obeyed, or it can go wrong: 1. Make sure no one else can re-queue the work anymore (in our case that's done by a combination of first updating output->crc_state and then waiting for the vblank to pass to make sure the hrtimer has noticed that change). 2. flush_work() 3. Actually clean up stuff (which isn't done here). Doing the flush_work before we even completed the output->state update, much less waited for the vblank to make sure that's happened, missed the point. Note that this is not yet race-free because of the hrtimer and crc worker look at the wrong state pointers, but that will be fixed in subsequent patches.
