The core also grew some lockdep annotations to try and constrain what drivers do with dma-fences, and added some documentation on why the idea of indefinite fences doesn't work. The long list is below. I do have some fixes trees outstanding, but I'll follow up with those later. core: - add user def flag to cmd line modes - dma_fence_wait added might_sleep - dma-fence lockdep annotations - indefinite fences are bad documentation - gem CMA functions used in more drivers - struct mutex removal - more drm_ debug macro usage - set/drop master api fixes - fix for drm/mm hole size comparison - drm/mm remove invalid entry optimization - optimise drm/mm hole handling - VRR debugfs added - uncompressed AFBC modifier support - multiple display id blocks in EDID - multiple driver sg handling fixes - __drm_atomic_helper_crtc_reset in all drivers - managed vram helpers ttm: - ttm_mem_reg handling cleanup - remove bo offset field - drop CMA memtype flag - drop mappable flag xilinx: - New Xilinx ZynqMP DisplayPort Subsystem driver nouveau: - add CRC support - start using NVIDIA published class header files - convert all push buffer emission to new macros - Proper push buffer space management for EVO/NVD channels. - firmware loading fixes - 2MiB system memory pages support on Pascal and newer vkms: - larger cursor support i915: - Rocketlake platform enablement - Early DG1 enablement - Numerous GEM refactorings - DP MST fixes - FBC, PSR, Cursor, Color, Gamma fixes - TGL, RKL, EHL workaround updates - TGL 8K display support fixes - SDVO/HDMI/DVI fixes amdgpu: - Initial support for Sienna Cichlid GPU - Initial support for Navy Flounder GPU - SI UVD/VCE support - expose rotation property - Add support for unique id on Arcturus - Enable runtime PM on vega10 boards that support BACO - Skip BAR resizing if the bios already did id - Major swSMU code cleanup - Fixes for DCN bandwidth calculations amdkfd: - Track SDMA usage per process - SMI events interface radeon: - Default to on chip GART for AGP boards on all arches - Runtime PM reference count fixes msm: - headers regenerated causing churn - a650/a640 display and GPU enablement - dpu dither support for 6bpc panels - dpu cursor fix - dsi/mdp5 enablement for sdm630/sdm636/sdm66 tegra: - video capture prep support - reflection support mediatek: - convert mtk_dsi to bridge API meson: - FBC support sun4i: - iommu support rockchip: - register locking fix - per-pixel alpha support PX30 VOP mgag200: - ported to simple and shmem helpers - device init cleanups - use managed pci functions - dropped hw cursor support ast: - use managed pci functions - use managed VRAM helpers - rework cursor support malidp: - dev_groups support hibmc: - refactor hibmc_drv_vdac: vc4: - create TXP CRTC imx: - error path fixes and cleanups etnaviv: - clock handling and error handling cleanups - use pin_user_pages" * tag 'drm-next-2020-08-06' of git://anongit.freedesktop.org/drm/drm: (1747 commits) drm/msm: use kthread_create_worker instead of kthread_run drm/msm/mdp5: Add MDP5 configuration for SDM636/660 drm/msm/dsi: Add DSI configuration for SDM660 drm/msm/mdp5: Add MDP5 configuration for SDM630 drm/msm/dsi: Add phy configuration for SDM630/636/660 drm/msm/a6xx: add A640/A650 hwcg drm/msm/a6xx: hwcg tables in gpulist drm/msm/dpu: add SM8250 to hw catalog drm/msm/dpu: add SM8150 to hw catalog drm/msm/dpu: intf timing path for displayport drm/msm/dpu: set missing flush bits for INTF_2 and INTF_3 drm/msm/dpu: don't use INTF_INPUT_CTRL feature on sdm845 drm/msm/dpu: move some sspp caps to dpu_caps drm/msm/dpu: update UBWC config for sm8150 and sm8250 drm/msm/dpu: use right setup_blend_config for sm8150 and sm8250 drm/msm/a6xx: set ubwc config for A640 and A650 drm/msm/adreno: un-open-code some packets drm/msm: sync generated headers drm/msm/a6xx: add build_bw_table for A640/A650 drm/msm/a6xx: fix crashstate capture for A650 ... 2020-07-26T16:04:06+00:00 Biju Das biju.das.jz@bp.renesas.com 2020-07-23T11:10:54+00:00 urn:sha1:4ee48cc5586bf519df19894273002aa8ef7b70ad Fix double-free bug in the error path.

This is undesirable behaviour in our case because absence of a panel/bridge graph is a valid case. Let's check the graph's presence in a device-tree before proceeding with parsing of the graph.

The device tree can be used to fully describe dual-link LVDS connections between encoders and bridges/panels. The sink of an LVDS dual-link connection is made of two ports, the corresponding OF graph port nodes can be marked with either dual-lvds-even-pixels or dual-lvds-odd-pixels, and that fully describes an LVDS dual-link connection, including pixel order. drm_of_lvds_get_dual_link_pixel_order is a new helper added by this patch, given the source port nodes it returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source port nodes belong to an LVDS dual-link connection, with even pixels expected to be generated from the first port, and odd pixels expected to be generated from the second port. If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS, odd pixels are expected to be generated from the first port, and even pixels from the other port.
