2022-09-07drm/amd/display: fix memory leak when using debugfs_lookup()Greg Kroah-Hartman
When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up by properly calling dput().

2022-09-07drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is ↵YiPeng Chai
uninstalled V1: The psp_cmd_submit_buf function is called by psp_hw_fini to send TA unload messages to psp to terminate ras, asd and tmr. But when amdgpu is uninstalled, drm_dev_unplug is called earlier than psp_hw_fini in amdgpu_pci_remove, the calling order as follows: static void amdgpu_pci_remove(struct pci_dev *pdev) { drm_dev_unplug ...... amdgpu_driver_unload_kms->amdgpu_device_fini_hw->... ->.hw_fini->psp_hw_fini->... ->psp_ta_unload->psp_cmd_submit_buf ...... } The program will return when calling drm_dev_enter in psp_cmd_submit_buf. So the call to drm_dev_enter in psp_cmd_submit_buf should be removed, so that the TA unload messages can be sent to the psp when amdgpu is uninstalled. V2: 1. Restore psp_cmd_submit_buf to its original code. 2. Move drm_dev_unplug call after amdgpu_driver_unload_kms in amdgpu_pci_remove. 3. Since amdgpu_device_fini_hw is called by amdgpu_driver_unload_kms, remove the unplug check to release device mmio resource in amdgpu_device_fini_hw before calling drm_dev_unplug.

2022-09-07drm: rcar-du: Fix DSI enable & disable sequenceTomi Valkeinen
The rcar crtc depends on the clock provided from the rcar DSI bridge. When the DSI bridge is disabled, the clock is stopped, which causes the crtc disable to timeout. Also, while I have no issue with the enable, the documentation suggests to enable the DSI before the crtc so that the crtc has its clock enabled at enable time. This is also not done by the current driver. To fix this, we need to keep the DSI bridge enabled until the crtc has disabled itself, and enable the DSI bridge before crtc enables itself. Add functions rcar_mipi_dsi_pclk_enable and rcar_mipi_dsi_pclk_disable to the rcar DSI bridge driver which the rcar driver can use to enable/disable the DSI clock when needed. This is similar to what is already done with the rcar LVDS bridge.

Also, support matching by patch level when selecting code paths for firmware compatibility.

2022-09-07drm/i915/uc: Support for version reduced and multiple firmware filesJohn Harrison
There was a misunderstanding in how firmware file compatibility should be managed within i915. This has been clarified as: i915 must support all existing firmware releases forever new minor firmware releases should replace prior versions only backwards compatibility breaking releases should be a new file This patch cleans up the single fallback file support that was added as a quick fix emergency effort. That is now removed in preference to supporting arbitrary numbers of firmware files per platform. The patch also adds support for having GuC firmware files that are named by major version only (because the major version indicates backwards breaking changes that affect the KMD) and for having HuC firmware files with no version number at all (because the KMD has no interface requirements with the HuC). For GuC, the driver will report via dmesg if the found file is older than expected. For HuC, the KMD will no longer require updating for any new HuC release so will not be able to report what the latest expected version is.

When do QXL_IO_RESET,QEMU will call init_qxl_ram(), so params like prod,cons,notify_on_cons and notify_on_prod will be set to default value. Ring push/pop actions for release_ring can be performed normally. But call qxl_ring_init_hdr(qdev->release_ring) will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE, affect the value of notify in qxl_push_free_res() function always be false, QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the guest qxl driver，so qxl_ring_pop() will never been called anymore， and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx) always return EBUSY,fail to call qxl_bo_create(). Test scenario: 1) start virtual machine with qemu command "-device qxl-vga" 2) click suspend botton to enter suspend mode 3) resume and observe the error message in kernel logs,screen will be black Let's fix this by reset io and remove the qxl_ring_init_hdr calling.

This commit fixes vertical timings of the VEC (composite output) modes to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R standards. Previous timings were actually defined as 502 and 601 lines, resulting in non-standard 62.69 Hz and 52 Hz signals being generated, respectively.

2022-09-07drm/via: Add new condition to via_dma_cleanup()Alisa Khabibrakhmanova
Pointer dev_priv->mmio, which was checked for NULL at via_do_init_map(), is passed to via_do_cleanup_map() and is dereferenced there without check. The patch adds the condition in via_dma_cleanup() which prevents potential NULL pointer dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE.
