[PATCH v6 0/6] Add Unisoc's drm kms module
by Kevin Tang 21 Oct '21

21 Oct '21

ChangeList: RFC v1: 1. only upstream modeset and atomic at first commit. 2. remove some unused code; 3. use alpha and blend_mode properties; 3. add yaml support; 4. remove auto-adaptive panel driver; 5. bugfix RFC v2: 1. add sprd crtc and plane module for KMS, preparing for multi crtc&encoder 2. remove gem drivers, use generic CMA handlers 3. remove redundant "module_init", all the sub modules loading by KMS RFC v3: 1. multi crtc&encoder design have problem, so rollback to v1 RFC v4: 1. update to gcc-linaro-7.5.0 2. update to Linux 5.6-rc3 3. remove pm_runtime support 4. add COMPILE_TEST, remove unused kconfig 5. "drm_dev_put" on drm_unbind 6. fix some naming convention issue 7. remove semaphore lock for crtc flip 8. remove static variables RFC v5: 1. optimize encoder and connector code implementation 2. use "platform_get_irq" and "platform_get_resource" 3. drop useless function return type, drop unless debug log 4. custom properties should be separate, so drop it 5. use DRM_XXX replase pr_xxx 6. drop dsi&dphy hal callback ops 7. drop unless callback ops checking 8. add comments for sprd dpu structure RFC v6: 1. Access registers via readl/writel 2. Checking for unsupported KMS properties (format, rotation, blend_mode, etc) on plane_check ops 3. Remove always true checks for dpu core ops RFC v7: 1. Fix DTC unit name warnings 2. Fix the problem of maintainers 3. Call drmm_mode_config_init to mode config init 4. Embed drm_device in sprd_drm and use devm_drm_dev_alloc 5. Replace DRM_XXX with drm_xxx on KMS module, but not suitable for other subsystems 6. Remove plane_update stuff, dpu handles all the HW update in crtc->atomic_flush 7. Dsi&Dphy Code structure adjustment, all move to "sprd/" v0: 1. Remove dpu_core_ops stuff layer for sprd drtc driver, but dpu_layer need to keeping. Because all the HW update in crtc->atomic_flush, we need temporary storage all layers for the dpu pageflip of atomic_flush. 2. Add ports subnode with port@X. v1: 1. Remove dphy and dsi graph binding, merge the dphy driver into the dsi. 2. Add commit messages for Unisoc's virtual nodes. v2: 1. Use drm_xxx to replace all DRM_XXX. 2. Use kzalloc to replace devm_kzalloc for sprd_dsi/sprd_dpu structure init. 3. Remove dpu_core_ops midlayer. v3: 1. Remove dpu_layer midlayer and commit layers by aotmic_update v4: 1. Move the devm_drm_dev_alloc to master_ops->bind function. 2. The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it. 3. Use drmm_helpers to allocate crtc ,planes and encoder. 4. Move allocate crtc ,planes, encoder to bind funtion. 5. Move rotation enum definitions to crtc layer reg bitfields. v5: 1. Remove subdir-ccflgas-y for Makefile. 2. Keep the selects sorted by alphabet for Kconfig. 3. Fix the checkpatch warnings. 4. Use mode_set_nofb instead of mode_valid callback. 5. Follow the OF-Graph bindings, use of_graph_get_port_by_id instead of of_parse_phandle. 6. Use zpos to represent the layer position. 7. Rebase to last drm misc branch. 8. Remove panel_in port for dsi node. 9. Drop the dsi ip file prefix. 10. Add Signed-off-by for dsi&dphy patch. 11. Use the mode_flags of mipi_dsi_device to setup crtc DPI and EDPI mode. v6: 1. Disable and clear interrupts before register dpu IRQ 2. Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb 3. Remove enable_irq and disable_irq function call. 4. Remove drm_format_info function call. 5. Redesign the way to access the dsi register. 6. Reduce the dsi_context member variables.

[PATCH] drm/bridge: dw-mipi-dsi: Find the possible DSI devices

Finding panel_or_bridge might vary based on associated DSI devices like DSI panel, bridge, and I2C based DSI bridge. 1.

[PATCH] dma-buf: Add support for mapping buffers with DMA attributes
by guangming.cao＠mediatek.com 18 Oct '21

18 Oct '21

From: Guangming Cao <Guangming.Cao(a)mediatek.com> When mapping the memory represented by a dma-buf into a device's address space, it might be desireable to map the memory with certain DMA attributes. Thus, introduce the dma_mapping_attrs field in the dma_buf_attachment structure so that when the memory is mapped with dma_buf_map_attachment, it is mapped with the desired DMA attributes.

[PATCH 0/4] drm: Make modeset locking easier
by Ville Syrjala 14 Oct '21

14 Oct '21

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> While staring at some DRM_MODESET_LOCK_ALL_{BEGIN,END}() conversions I decided I don't really like what those macros do. The main problems that I see: - the magic goto inside limits their usefulness to baically a single statement, unless you're willing to look inside and find out the name of the magic label - can't help at all in the "we don't want to lock everything" cases, which are quite numerous - not at all obvious that there's a loop in there So I figured I'd try to come up with something more universally useful.

[PATCH v8 0/4] drm: LogiCVC display controller support
by Paul Kocialkowski 13 Oct '21

13 Oct '21

This series introduces support for the LogiCVC display controller. The controller is a bit unusual since it is usually loaded as programmable logic on Xilinx FPGAs or Zynq-7000 SoCs. More details are presented on the main commit for the driver. More information about the controller is available on the dedicated web page: https://www.logicbricks.com/Products/logiCVC-ML.aspx Note that this driver has rather simple connector management, which was not converted to drm_panel_bridge to keep the ability to enable the panel at first vblank but also to support DVI. Change since v7: - Replaced DRM_INFO/DRM_ERROR/DRM_DEBUG_DRIVER with fashions using drm_device; - Fixed yaml binding alignment issue; - Renamed logicvc-display name to the generic "display" name; - Added patternProperties match for display in the parent mfd binding; - Used drm_atomic_get_new_crtc_state when needed; - Checked mode in mode_valid instead of atomic_check; - Switched to drmm_mode_config_init; - Removed useless logicvc_connector_destroy wrapper; - Removed useless drm_dev_put calls; - Removed atomic_commit_tail that enables the panel and streamlined the logic; - Reworked Makefile cosmetics; - Fixed checkpatch issues. Changes since v6: - Updated to the latest DRM internal API changes; - Used an enum to index dt properties instead of the name string. Changes since v5: - Subclass DRM device and use devm_drm_dev_alloc for allocation; - Removed call to drm_mode_config_cleanup (done automatically with devm); - Some related code cleanups; - Bring back not-for-merge patch adding colorkey support. Changes since v4: - Updated to internal DRM API changes (rebased on drm-misc-next); - Added Kconfig dependency on OF; - Added MAINTAINERS entry; - Used drm_err and dev_err instead of DRM_ERROR where possible; - Various cosmetic changes. Changes since v3: - Rebased on latest drm-misc; - Improved event lock wrapping; - Added collect tag; - Added color-key support patch (not for merge, for reference only). Changes since v2: - Fixed and slightly improved dt schema. Changes since v1: - Switched dt bindings documentation to dt schema; - Described more possible dt parameters; - Added support for the lvds-3bit interface; - Added support for grabbing syscon regmap from parent node; - Removed layers count property and count layers child nodes instead.
