[PATCH v2] drm/msm/dsi: use RMW cycles in dsi_update_dsc_timing

The downstream uses read-modify-write for updating command mode compression registers. Let's follow this approach.

[PATCH 0/3] drm/{ast, mgag200}: Protect I/O regs against concurrent access
by Thomas Zimmermann 04 May '22

04 May '22

Protect access to I/O registers in ast and mgag200 via lock. Commit- tail functions and get-modes operations use the same registers and can interfere with each other. This can result in failed mode-setting operations. As both drivers use fully managed cleanup, the patchset adds a new helper that initializes a mutex with auto-cleanup.

[PATCH v2] fbdev: Use helper to get fb_info in all file operations
by Javier Martinez Canillas 04 May '22

04 May '22

A reference to the framebuffer device struct fb_info is stored in the file private data, but this reference could no longer be valid and must not be accessed directly. Instead, the file_fb_info() accessor function must be used since it does sanity checking to make sure that the fb_info is valid. This can happen for example if the registered framebuffer device is for a driver that just uses a framebuffer provided by the system firmware. In that case, the fbdev core would unregister the framebuffer device when a real video driver is probed and ask to remove conflicting framebuffers. Most fbdev file operations already use the helper to get the fb_info but get_fb_unmapped_area() and fb_deferred_io_fsync() don't. Fix those two. Since fb_deferred_io_fsync() is not in fbmem.o, the helper has to be exported. Rename it and add a fb_ prefix to denote that is public now.

[PATCH] Revert "fbdev: Make fb_release() return -ENODEV if fbdev was unregistered"
by Javier Martinez Canillas 04 May '22

04 May '22

This reverts commit aafa025c76dcc7d1a8c8f0bdefcbe4eb480b2f6a. That commit attempted to fix a NULL pointer dereference, caused by the struct fb_info associated with a framebuffer device to not longer be valid when the file descriptor was closed. But the solution was wrong since it was just papering over the issue, and also would leak any resources that might be reference counted in fb_open. Instead, the fbdev drivers that are releasing the fb_info too soon should be fixed to prevent this situation to happen.

Hello, This small series contains fixes for two bugs I found in fbmem.c, that may explain a bug reported in the rpi4 [0] when using simplefb and vc4 drivers. I was not able to reproduce the mentioned bug, but looking at the code I think that it might explain the issue. I've tested these patches in a rpi4 with both simplefb and vc4 drivers built-in and did not find any regression.

[PATCH 0/3] i915 private writeback framework
by Suraj Kandpal 04 May '22

04 May '22

A patch series was floated in the drm mailing list which aimed to change the drm_connector and drm_encoder fields to pointer in the drm_connector_writeback structure, this received a huge pushback from the community but since i915 expects each connector present in the drm_device list to be a intel_connector but drm_writeback framework. [1] https://patchwork.kernel.org/project/dri-devel/patch/20220202081702.22119-1… [2] https://patchwork.kernel.org/project/dri-devel/patch/20220202085429.22261-6… This forces us to use a drm_connector which is not embedded in intel_connector the current drm_writeback framework becomes very unfeasible to us as it would mean a lot of checks at a lot of places to take into account the above issue.Since no one had an issue with encoder field being changed into a pointer it was decided to break the connector and encoder pointer changes into two different series.The encoder field changes is currently being worked upon by Abhinav Kumar [3]https://patchwork.kernel.org/project/dri-devel/list/?series=633565 In the meantime for i915 to start using the writeback functionality we came up with a interim solution to own writeback pipeline bypassing one provided by drm which is what these patches do. Note: these are temp patches till we figure out how we can either change drm core writeback to work with our intel_connector structure or find a different solution which allows us to work with the current Suraj Kandpal (3): drm/i915: Creating writeback pipeline to bypass drm_writeback framework drm/i915: Define WD trancoder for i915 drm/i915: Enabling WD Transcoder drivers/gpu/drm/i915/Makefile | 2 + drivers/gpu/drm/i915/display/intel_acpi.c | 1 + drivers/gpu/drm/i915/display/intel_display.c | 89 +- drivers/gpu/drm/i915/display/intel_display.h | 15 + .../drm/i915/display/intel_display_types.h | 18 + drivers/gpu/drm/i915/display/intel_dpll.c | 3 + drivers/gpu/drm/i915/display/intel_opregion.c | 3 + .../gpu/drm/i915/display/intel_wb_connector.c | 296 ++++++ .../gpu/drm/i915/display/intel_wb_connector.h | 99 ++ drivers/gpu/drm/i915/display/intel_wd.c | 978 ++++++++++++++++++ drivers/gpu/drm/i915/display/intel_wd.h | 82 ++ drivers/gpu/drm/i915/i915_drv.h | 5 + drivers/gpu/drm/i915/i915_irq.c | 8 +- drivers/gpu/drm/i915/i915_pci.c | 7 +- drivers/gpu/drm/i915/i915_reg.h | 139 +++ 15 files changed, 1742 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/i915/display/intel_wb_connector.c create mode 100644 drivers/gpu/drm/i915/display/intel_wb_connector.h create mode 100644 drivers/gpu/drm/i915/display/intel_wd.c create mode 100644 drivers/gpu/drm/i915/display/intel_wd.h -- 2.35.1
