2025-07-08drm/rockchip: vop2: Fix the update of LAYER/PORT select registers when there ↵Andy Yan
are multi display output on rk3588/rk3568 The all video ports of rk3568/rk3588 share the same OVL_LAYER_SEL and OVL_PORT_SEL registers, and the configuration of these two registers can be set to take effect when the vsync signal arrives at a certain Video Port. If two threads for two display output choose to update these two registers simultaneously to meet their own plane adjustment requirements(change plane zpos or switch plane from one crtc to another), then no matter which Video Port'svsync signal we choose to follow for these two registers, the display output of the other Video Port will be abnormal. This is because the configuration of this Video Port does not take effect at the right time (its configuration should take effect when its VSYNC signal arrives). In order to solve this problem, when performing plane migration or change the zpos of planes, there are two things to be observed and followed: 1. When a plane is migrated from one VP to another, the configuration of the layer can only take effect after the Port mux configuration is enabled. 2. When change the zpos of planes, we must ensure that the change for the previous VP takes effect before we proceed to change the next VP. Otherwise, the new configuration might overwrite the previous one for the previous VP, or it could lead to the configuration of the previous VP being take effect along with the VSYNC of the new VP. This issue only occurs in scenarios where multi-display output is enabled.

2025-07-08drm/rockchip: vop2: fail cleanly if missing a primary plane for a video-portHeiko Stuebner
Each window of a vop2 is usable by a specific set of video ports, so while binding the vop2, we look through the list of available windows trying to find one designated as primary-plane and usable by that specific port. The code later wants to use drm_crtc_init_with_planes with that found primary plane, but nothing has checked so far if a primary plane was actually found. For whatever reason, the rk3576 vp2 does not have a usable primary window (if vp0 is also in use) which brought the issue to light and ended in a null-pointer dereference further down. As we expect a primary-plane to exist for a video-port, add a check at the end of the window-iteration and fail probing if none was found.

2025-03-02drm/rockchip: vop2: use devm_regmap_field_alloc for cluster-regsAndy Yan
Right now vop2_cluster_init() copies the base vop2_cluster_regs and adapts the reg value with the current window's offset before adding the fields to the regmap. This conflicts with the notion of reg_fields being const, see https://lore.kernel.org/all/20240706-regmap-const-structs-v1-1-d08c776da787@weissschuh.net/ for reference, which now causes checkpatch to actually warn about that. So instead of creating one big copy and changing it afterwards, add the reg_fields individually using devm_regmap_field_alloc(). Functional it is the same, just that the reg_field we're handling can stay const.

2024-11-09rockchip/drm: vop2: add support for gamma LUTPiotr Zalewski
Add support for gamma LUT in VOP2 driver. The implementation was inspired by one found in VOP1 driver. Blue and red channels in gamma LUT register write were swapped with respect to how gamma LUT values are written in VOP1. Gamma LUT port selection was added before the write of new gamma LUT table. If the current SoC is rk356x, check if no other CRTC has gamma LUT enabled in atomic_check (only one video port can use gamma LUT at a time) and disable gamma LUT before the LUT table write. If the current SoC isn't rk356x, "seamless" gamma lut update is performed similarly to how it was done in the case of RK3399 in VOP1[1]. In seamless update gamma LUT disable before the write isn't necessary, check if no other CRTC has gamma LUT enabled is also not necessary, different register is being used to select gamma LUT port[2] and after setting DSP_LUT_EN bit, GAMMA_UPDATE_EN bit is set[3]. Gamma size is set and drm color management is enabled for each video port's CRTC except ones which have no associated device. Patch was tested on RK3566 (Pinetab2). When using userspace tools which set eg. constant color temperature no issues were noticed. When using userspace tools which adjust eg. color temperature the slight screen flicker is visible probably because of gamma LUT disable needed in the case of RK356x before gamma LUT write. Compare behaviour of eg.: ``` gammastep -O 3000 ``` To eg.: ``` gammastep -l 53:23 -t 6000:3000 ``` In latter case color temperature is slowly adjusted at the beginning which causes screen to slighly flicker. Then it adjusts every few seconds which also causes slight screen flicker.

For the cbcr format, gt2 and gt4 are computed again after src_h has been divided by vsub. As src_h as already been divided by 2 before, introduce cbcr_src_h and cbcr_src_w to keep a copy of those values to be used for cbcr gt2 and gt4 computation. This fixes yuv planes being unaligned vertically when down scaling to 1080 pixels from 2160.

Marek Report a possible irq lock inversion dependency warning when commit 81a06f1d02e5 ("Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"") lands linux-next.

One solution is switch back to REGCACHE_RBTREE, but it seems that REGCACHE_MAPLE is the future, so I avoid using regmap_reinit_cache, and drop all the regcache when vop is disabled, then we get a fresh start at next enbable time.
