2024-04-25drm/i915: Initialize fbdev DRM client with callback functionsThomas Zimmermann
Initialize i915's fbdev client by giving an instance of struct drm_client_funcs to drm_client_init(). Also clean up with drm_client_release(). Doing this in i915 prevents fbdev helpers from initializing and releasing the client internally (see drm_fb_helper_init()). No functional change yet; the client callbacks will be filled later. v6: - rename client to "intel-fbdev" (Jouni) v2: - call drm_fb_helper_unprepare() in error handling (Jani) - fix typo in commit message (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409081029.17843-4-tzimmermann@suse.de Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2024-04-25drm/i915: convert _MMIO_PIPE3()/_MMIO_PORT3() to accept baseJani Nikula
Most users of _MMIO_PIPE3() and _MMIO_PORT3() need to add the MMIO base to the registers. Convert the macros to _MMIO_BASE_PIPE3() and _MMIO_BASE_PORT3() to move the base addition until after the register selection. If the register address depends on DISPLAY_MMIO_BASE(), this removes the need to figure the base out for each register, and it only needs to be added once.

2024-04-25gpu: drm: exynos: hdmi: eliminate uses of of_node_put()Shivani Gupta
Utilize the __free() cleanup handler within the hdmi_get_phy_io function to automatically release the device node when it is out of scope. This eliminates the manual invocation of of_node_put(), reducing the potential for memory leaks. The modification requires initializing the device node at the beginning of the function, ensuring that the automatic cleanup is safely executed. Consequently, this removes the need for error cleanup paths that utilize goto statements and the jump to out is no longer necessary.

2024-04-24drm/i915: Fix gt reset with GuC submission is disabledNirmoy Das
Currently intel_gt_reset() kills the GuC and then resets requested engines. This is problematic because there is a dedicated CSB FIFO which only GuC can access and if that FIFO fills up, the hardware will block on the next context switch until there is space that means the system is effectively hung. If an engine is reset whilst actively executing a context, a CSB entry will be sent to say that the context has gone idle. Thus if reset happens on a very busy system then killing GuC before killing the engines will lead to deadlock because of filled up CSB FIFO. To address this issue, the GuC should be killed only after resetting the requested engines and before calling intel_gt_init_hw(). v2: Improve commit message(John) Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240422201951.633-2-nirmoy.das@intel.com

2024-04-23drm/amd/pm: Restore config space after resetLijo Lazar
During mode-2 reset, pci config space registers are affected at device side. However, certain platforms have switches which assign virtual BAR addresses and returns the same even after device is reset. This affects pci_restore_state() as it doesn't issue another config write, if the value read is same as the saved value. Add a workaround to write saved config space values from driver side. Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence restrict the workaround only to those.

2024-04-23drm/amdgpu/umsch: don't execute umsch test when GPU is in reset/suspendLang Yu
umsch test needs full GPU functionality(e.g., VM update, TLB flush, possibly buffer moving under memory pressure) which may be not ready under these states. Just skip it to avoid potential issues.

2024-04-23drm/amdgpu: Update BO eviction prioritiesFelix Kuehling
Make SVM BOs more likely to get evicted than other BOs. These BOs opportunistically use available VRAM, but can fall back relatively seamlessly to system memory. It also avoids SVM migrations evicting other, more important BOs as they will evict other SVM allocations first.
