drm/rockchip: vop2: use correct destination rectangle height check

2025-10-23T14:20:35+00:00

[ Upstream commit 7f38a1487555604bc4e210fa7cc9b1bce981c40e ] The vop2_plane_atomic_check() function incorrectly checks drm_rect_width(dest) twice instead of verifying both width and height. Fix the second condition to use drm_rect_height(dest) so that invalid destination rectangles with height < 4 are correctly rejected.

drm/rockchip: cleanup fb when drm_gem_fb_afbc_init failed

2025-08-15T10:13:38+00:00

[ Upstream commit 099593a28138b48feea5be8ce700e5bc4565e31d ] In the function drm_gem_fb_init_with_funcs, the framebuffer (fb) and its corresponding object ID have already been registered. So we need to cleanup the drm framebuffer if the subsequent execution of drm_gem_fb_afbc_init fails. Directly call drm_framebuffer_put to ensure that all fb related resources are cleanup.

drm/rockchip: vop2: Improve display modes handling on RK3588 HDMI0

2025-05-29T09:03:00+00:00

[ Upstream commit 2c1268e7aad0819f38e56134bbc2095fd95fde1b ] The RK3588 specific implementation is currently quite limited in terms of handling the full range of display modes supported by the connected screens, e.g. 2560x1440@75Hz, 2048x1152@60Hz, 1024x768@60Hz are just a few of them. Additionally, it doesn't cope well with non-integer refresh rates like 59.94, 29.97, 23.98, etc. Make use of HDMI0 PHY PLL as a more accurate DCLK source to handle all display modes up to 4K@60Hz.

drm/rockchip: vop2: Add uv swap for cluster window

2025-05-29T09:02:32+00:00

[ Upstream commit e7aae9f6d762139f8d2b86db03793ae0ab3dd802 ] The Cluster windows of upcoming VOP on rk3576 also support linear YUV support, we need to set uv swap bit for it. As the VOP2_WIN_UV_SWA register defined on rk3568/rk3588 is 0xffffffff, so this register will not be touched on these two platforms.

drm/rockchip: cdn-dp: Use drm_connector_helper_hpd_irq_event()

2025-02-17T09:05:05+00:00

commit 666e1960464140cc4bc9203c203097e70b54c95a upstream. The code for detecting and updating the connector status in cdn_dp_pd_event_work() has a number of problems. - It does not aquire the locks to call the detect helper and update the connector status. These are struct drm_mode_config.connection_mutex and struct drm_mode_config.mutex. - It does not use drm_helper_probe_detect(), which helps with the details of locking and detection. - It uses the connector's status field to determine a change to the connector status. The epoch_counter field is the correct one. The field signals a change even if the connector status' value did not change. Replace the code with a call to drm_connector_helper_hpd_irq_event(), which fixes all these problems.
