drm/rockchip: Require the YTR modifier for AFBC

2021-03-04T11:15:24+00:00

commit 5f94e3571459abb626077aedb65d71264c2a58c0 upstream. The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption. The upstream AFBC support was developed against a captured frame, which failed to exercise modifier support. Prior to bring-up of AFBC in Mesa (in the Panfrost driver), no open userspace respected modifier reporting. As such, this change is not expected to affect broken userspaces. Tested on RK3399 with Panfrost and Weston.

drm/rockchip: Avoid uninitialized use of endpoint id in LVDS

2020-11-29T16:33:32+00:00

In the Rockchip DRM LVDS component driver, the endpoint id provided to drm_of_find_panel_or_bridge is grabbed from the endpoint's reg property. However, the property may be missing in the case of a single endpoint. Initialize the endpoint_id variable to 0 to avoid using an uninitialized variable in that case.

drm: Use state helper instead of CRTC state pointer

2020-11-10T11:41:06+00:00

Many drivers reference the crtc->pointer in order to get the current CRTC state in their atomic_begin or atomic_flush hooks, which would be the new CRTC state in the global atomic state since _swap_state happened when those hooks are run. Use the drm_atomic_get_new_crtc_state helper to get that state to make it more obvious. This was made using the coccinelle script below: @ crtc_atomic_func @ identifier helpers; identifier func; @@ ( static struct drm_crtc_helper_funcs helpers = { ..., .atomic_begin = func, ..., }; | static struct drm_crtc_helper_funcs helpers = { ..., .atomic_flush = func, ..., }; ) @@ identifier crtc_atomic_func.func; identifier crtc, state; symbol crtc_state; expression e; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct tegra_dc_state *crtc_state = e; + struct tegra_dc_state *dc_state = e; <+... - crtc_state + dc_state ...+> } @@ identifier crtc_atomic_func.func; identifier crtc, state; symbol crtc_state; expression e; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct mtk_crtc_state *crtc_state = e; + struct mtk_crtc_state *mtk_crtc_state = e; <+... - crtc_state + mtk_crtc_state ...+> } @ replaces_new_state @ identifier crtc_atomic_func.func; identifier crtc, state, crtc_state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct drm_crtc_state *crtc_state = crtc->state; + struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... } @@ identifier crtc_atomic_func.func; identifier crtc, state, crtc_state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... - crtc->state + crtc_state ... } @ adds_new_state @ identifier crtc_atomic_func.func; identifier crtc, state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { + struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... - crtc->state + crtc_state ... } @ include depends on adds_new_state || replaces_new_state @ @@ #include @ no_include depends on !include && (adds_new_state || replaces_new_state) @ @@ + #include #include Suggested-by: Ville Syrjälä Signed-off-by: Maxime Ripard Reviewed-by: Ville Syrjälä Acked-by: Thomas Zimmermann Cc: "James (Qian) Wang" Cc: Liviu Dudau Cc: Mihail Atanassov Cc: Brian Starkey Cc: Russell King Cc: Paul Cercueil Cc: Chun-Kuang Hu Cc: Philipp Zabel Cc: Sandy Huang Cc: "Heiko Stübner" Cc: Thierry Reding Cc: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20201105164518.392891-1-maxime@cerno.tech

drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backends

2020-11-09T08:19:24+00:00

This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al.

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch

drm/atomic: Pass the full state to CRTC atomic begin and flush

2020-11-02T11:37:49+00:00

The current atomic helpers have either their object state being passed as an argument or the full atomic state. The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed. Let's start convert all the remaining helpers to provide a consistent interface, starting with the CRTC's atomic_begin and atomic_flush.
