drm/rockchip: vop: Fix color for RGB888/BGR888 format on VOP full

2023-12-03T06:32:07+00:00

[ Upstream commit bb0a05acd6121ff0e810b44fdc24dbdfaa46b642 ] Use of DRM_FORMAT_RGB888 and DRM_FORMAT_BGR888 on e.g. RK3288, RK3328 and RK3399 result in wrong colors being displayed. The issue can be observed using modetest: modetest -s @:1920x1080-60@RG24 modetest -s @:1920x1080-60@BG24 Vendor 4.4 kernel apply an inverted rb swap for these formats on VOP full framework (IP version 3.x) compared to VOP little framework (2.x). Fix colors by applying different rb swap for VOP full framework (3.x) and VOP little framework (2.x) similar to vendor 4.4 kernel.

drm/rockchip: Fix type promotion bug in rockchip_gem_iommu_map()

2023-11-20T10:52:00+00:00

[ Upstream commit 6471da5ee311d53ef46eebcb7725bc94266cc0cf ] The "ret" variable is declared as ssize_t and it can hold negative error codes but the "rk_obj->base.size" variable is type size_t. This means that when we compare them, they are both type promoted to size_t and the negative error code becomes a high unsigned value and is treated as success. Add a cast to fix this.

drm/rockchip: vop2: Don't crash for invalid duplicate_state

drm/rockchip: vop: Leave vblank enabled in self-refresh

2023-07-23T11:49:39+00:00

commit 2bdba9d4a3baa758c2ca7f5b37b35c7b3391dc42 upstream. If we disable vblank when entering self-refresh, vblank APIs (like DRM_IOCTL_WAIT_VBLANK) no longer work. But user space is not aware when we enter self-refresh, so this appears to be an API violation -- that DRM_IOCTL_WAIT_VBLANK fails with EINVAL whenever the display is idle and enters self-refresh. The downstream driver used by many of these systems never used to disable vblank for PSR, and in fact, even upstream, we didn't do that until radically redesigning the state machine in commit 6c836d965bad ("drm/rockchip: Use the helpers for PSR"). Thus, it seems like a reasonable API fix to simply restore that behavior, and leave vblank enabled. Note that this appears to potentially unbalance the drm_crtc_vblank_{off,on}() calls in some cases, but: (a) drm_crtc_vblank_on() documents this as OK and (b) if I do the naive balancing, I find state machine issues such that we're not in sync properly; so it's easier to take advantage of (a). This issue was exposed by IGT's kms_vblank tests, and reported by KernelCI. The bug has been around a while (longer than KernelCI noticed), but was only exposed once self-refresh was bugfixed more recently, and so KernelCI could properly test it.
