[PATCH] drm: bridge: icn6211: Adjust clock phase using SYS_CTRL_1
by Jonathan Liu 23 May '22

23 May '22

The code from [1] sets SYS_CTRL_1 to different values depending on the desired clock phase (0, 1/4, 1/2 or 3/4). A clock phase of 0 aligns the positive edge of the clock with the pixel data while other values delay the clock by a fraction of the clock period. A clock phase of 1/2 aligns the negative edge of the clock with the pixel data. The driver currently hard codes SYS_CTRL_1 to 0x88 which corresponds to aligning the positive edge of the clock with the pixel data. This won't work correctly for panels that require aligning the negative edge of the clock with the pixel data. Adjust the clock phase to 0 if DRM_BUS_FLAG_PIXDATA_DRIVE_POSEDGE is present in bus_flags, otherwise adjust the clock phase to 1/2 as appropriate for DRM_BUS_FLAG_PIXDATA_DRIVE_NEGEDGE.

[PULL] drm-intel-next -> drm-intel-gt-next cross-merge sync
by Jani Nikula 23 May '22

23 May '22

Hi all, This is for Tvrtko to pull to cross-merge sync drm-intel-next to drm-intel-gt-next. Dave, Daniel, IIUC this is what you prefer over having topic branches for all the small things that are needed between drm-intel branches. I don't think we've done this direct cross-merge before, so decided to send a pull request for transparency. Do you want us to do it this way going forward, or can we just do direct merges in git branches without tagged pull requests? Looks like drm-intel-next is ahead wrt backmerges too, so this pulls in some drm-next to drm-intel-gt-next too. BR, Jani. PS. For future reference, generated using: $ dim pull-request drm-intel-next drm-intel/drm-intel-gt-next The following changes since commit c54b39a565227538c52ead2349eb17d54aadd6f7: Merge tag 'drm-intel-next-2022-04-13-1' of git://anongit.freedesktop.org/drm/drm-intel into drm-next (2022-04-14 12:03:09 +1000) are available in the Git repository at: git://anongit.freedesktop.org/drm/drm-intel tags/drm-intel-next-2022-05-20 for you to fetch changes up to 5f38c3fb55ce3814b4353320d7a205068a420e48: drm/i915/pcode: Add a couple of pcode helpers (2022-05-20 09:11:45 +0100) ---------------------------------------------------------------- drm/i915 drm-intel-next -> drm-intel-gt-next cross-merge sync ---------------------------------------------------------------- Anshuman Gupta (1): drm/i915: Use drm_dbg for rpm logging Anusha Srivatsa (2): drm/i915/dmc: Load DMC on DG2 drm/i915/dmc: Add MMIO range restrictions Arunpravin Paneer Selvam (2): drm/amdgpu: add drm buddy support to amdgpu drm: add a check to verify the size alignment Ashutosh Dixit (2): drm/i915: Introduce has_media_ratio_mode drm/i915/pcode: Extend pcode functions for multiple gt's Biju Das (1): drm: bridge: adv7511: Enable DRM_BRIDGE_OP_HPD based on HPD interrupt Changcheng Deng (1): fbcon: use min() to make code cleaner Chen-Yu Tsai (4): dt-bindings: vendor-prefixes: Add prefix for SINO WEALTH Eletronics Ltd. dt-bindings: display: ssd1307fb: Add entry for SINO WEALTH SH1106 drm/ssd130x: Support page addressing mode drm/ssd130x: Add support for SINO WEALTH SH1106 Christian König (16): dma-buf: add enum dma_resv_usage v4 dma-buf: specify usage while adding fences to dma_resv obj v7 dma-buf & drm/amdgpu: remove dma_resv workaround dma-buf: add DMA_RESV_USAGE_KERNEL v3 drm/amdgpu: use DMA_RESV_USAGE_KERNEL drm/radeon: use DMA_RESV_USAGE_KERNEL RDMA: use DMA_RESV_USAGE_KERNEL dma-buf: add DMA_RESV_USAGE_BOOKKEEP v3 dma-buf: wait for map to complete for static attachments drm/i915: drop bo->moving dependency drm/ttm: remove bo->moving dma-buf: drop seq count based update seqlock: drop seqcount_ww_mutex_t futex: add missing rtmutex.h include drm/ttm: fix logic inversion in ttm_eu_reserve_buffers drm/ttm: fix kerneldoc for ttm_lru_bulk_move Christoph Hellwig (27): drm/i915/gvt: remove module refcounting in intel_gvt_{,un}register_hypervisor drm/i915/gvt: remove enum hypervisor_type drm/i915/gvt: rename intel_vgpu_ops to intel_vgpu_mdev_ops drm/i915/gvt: move the gvt code into kvmgt.ko drm/i915/gvt: remove intel_gvt_ops drm/i915/gvt: remove the map_gfn_to_mfn and set_trap_area ops drm/i915/gvt: remove the unused from_virt_to_mfn op drm/i915/gvt: merge struct kvmgt_vdev into struct intel_vgpu drm/i915/gvt: merge struct kvmgt_guest_info into strut intel_vgpu drm/i915/gvt: remove vgpu->handle drm/i915/gvt: devirtualize ->{read,write}_gpa drm/i915/gvt: devirtualize ->{get,put}_vfio_device drm/i915/gvt: devirtualize ->set_edid and ->set_opregion drm/i915/gvt: devirtualize ->detach_vgpu drm/i915/gvt: devirtualize ->inject_msi drm/i915/gvt: devirtualize ->is_valid_gfn drm/i915/gvt: devirtualize ->gfn_to_mfn drm/i915/gvt: devirtualize ->{enable,disable}_page_track drm/i915/gvt: devirtualize ->dma_{,un}map_guest_page drm/i915/gvt: devirtualize dma_pin_guest_page drm/i915/gvt: remove struct intel_gvt_mpt drm/i915/gvt: remove the extra vfio_device refcounting for dmabufs drm/i915/gvt: streamline intel_vgpu_create drm/i915/gvt: pass a struct intel_vgpu to the vfio read/write helpers drm/i915/gvt: remove kvmgt_guest_{init,exit} drm/i915/gvt: convert to use vfio_register_emulated_iommu_dev drm/i915/gvt: merge gvt.c into kvmgvt.c Colin Ian King (1): drm: sti: fix spelling mistake: rejec -> rejection Dale B Stimson (1): drm/i915/pcode: Add a couple of pcode helpers Daniel Vetter (18): fbcon: delete a few unneeded forward decl fbcon: Move fbcon_bmove(_rec) functions fbcon: Introduce wrapper for console->fb_info lookup fbcon: delete delayed loading code fbdev/sysfs: Fix locking fbcon: Use delayed work for cursor fbcon: Replace FBCON_FLAGS_INIT with a boolean fb: Delete fb_info->queue fbcon: Extract fbcon_open/release helpers fbcon: Ditch error handling for con2fb_release_oldinfo fbcon: move more common code into fb_open() fbcon: use lock_fb_info in fbcon_open/release fbcon: Consistently protect deferred_takeover with console_lock() fbcon: Move console_lock for register/unlink/unregister fbcon: Move more code into fbcon_release fbcon: untangle fbcon_exit fbcon: Maintain a private array of fb_info fbcon: Fix delayed takeover locking Dave Airlie (1): Merge tag 'drm-misc-next-2022-04-21' of git://anongit.freedesktop.org/drm/drm-misc into drm-next Devarsh Thakkar (1): drm/tidss: Soft Reset DISPC on startup H.

[PATCH] drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync
by Huacai Chen 23 May '22

23 May '22

Consider a configuration like this: 1, efifb (or simpledrm) is built-in; 2, a native display driver (such as radeon) is also built-in. Because efifb, radeon and sysfb are all in device_initcall() level, the order in practise is like this: efifb registered at first, but no "efi-framebuffer" device yet. radeon registered later, and /dev/fb0 created. sysfb_init() comes at last, it registers "efi-framebuffer" and then causes an error message "efifb: a framebuffer is already registered". Make sysfb_init() to be subsys_ initcall_sync() can avoid this. But Javier Martinez Canillas has a more general solution. However, this patch still makes sense because it can make the screen display as early as possible (We cannot move to subsys_initcall, since sysfb_init() should be executed after PCI enumeration).

[PATCH] drm: msm: fix possible memory leak in mdp5_crtc_cursor_set()
by Hangyu Hua 23 May '22

drm_gem_object_lookup will call drm_gem_object_get inside. So cursor_bo needs to be put when msm_gem_get_and_pin_iova fails.
