2023-01-19drm/amd: decrease message about missing PSP runtime database to debugMario Limonciello
Laptops with APUs from a variety of manufacturers and generations show a warning about a missing PSP runtime database. As it's not required for PSP to dump this database into framebuffer, decrease messages about it missing to debug.

2023-01-19accel/ivpu: Add command buffer submission logicJacek Lawrynowicz
Each of the user contexts has two command queues, one for compute engine and one for the copy engine. Command queues are allocated and registered in the device when the first job (command buffer) is submitted from the user space to the VPU device. The userspace provides a list of GEM buffer object handles to submit to the VPU, the driver resolves buffer handles, pins physical memory if needed, increments ref count for each buffer and stores pointers to buffer objects in the ivpu_job objects that track jobs submitted to the device. The VPU signals job completion with an asynchronous message that contains the job id passed to firmware when the job was submitted. Currently, the driver supports simple scheduling logic where jobs submitted from user space are immediately pushed to the VPU device command queues. In the future, it will be extended to use hardware base scheduling and/or drm_sched.

2023-01-19accel/ivpu: Add Intel VPU MMU supportJacek Lawrynowicz
VPU Memory Management Unit is based on ARM MMU-600. It allows the creation of multiple virtual address spaces for the device and map noncontinuous host memory (there is no dedicated memory on the VPU). Address space is implemented as a struct ivpu_mmu_context, it has an ID, drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that holds actual 3-level, 4KB page table. Context with ID 0 (global context) is created upon driver initialization and it's mainly used for mapping memory required to execute the firmware. Contexts with non-zero IDs are user contexts allocated each time the devices is open()-ed and they map command buffers and other workload-related memory. Workloads executing in a given contexts have access only to the memory mapped in this context.

2023-01-19drm/edid: use VIC in AVI infoframe if sink lists it in CTA VDBJani Nikula
Apparently there are HDMI 1.4 compatible displays out there that support VICs from specs later than CTA-861-D, i.e. VIC > 64, although HDMI 1.4 references CTA-861-D only. We try to avoid using VICs from the later specs in the AVI infoframes to avoid upsetting sinks that conform to earlier specs. However, it seems reasonable to do this when the sink claims it supports the VIC. With the pre-parsed list of VICs handy, this is now trivial.

Commit 537d9ed2f6c1 ("drm/edid: convert add_cea_modes() to use cea db iter") inadvertently moved the do_hdmi_vsdb_modes() call within the db iteration loop, always passing NULL as the CTA VDB to do_hdmi_vsdb_modes(), skipping a lot of stereo modes. Move the call back outside of the loop. This does mean only one CTA VDB and HDMI VSDB combination will be handled, but it's an unlikely scenario to have more than one of either block, and it was not accounted for before the regression either.

2023-01-19drm/edid: fix AVI infoframe aspect ratio handlingJani Nikula
We try to avoid sending VICs defined in the later specs in AVI infoframes to sinks that conform to the earlier specs, to not upset them, and use 0 for the VIC instead. However, we do this detection and conversion to 0 too early, as we'll need the actual VIC to figure out the aspect ratio. In particular, for a mode with 64:27 aspect ratio, 0 for VIC fails the AVI infoframe generation altogether with -EINVAL. Separate the VIC lookup from the "filtering", and postpone the filtering, to use the proper VIC for aspect ratio handling, and the 0 VIC for the infoframe video code as needed.

2023-01-19drm/mipi-dsi: Fix byte order of 16-bit DCS set/get brightnessDaniel Mentz
The MIPI DCS specification demands that brightness values are sent in big endian byte order. It also states that one parameter (i.e. one byte) shall be sent/received for 8 bit wide values, and two parameters shall be used for values that are between 9 and 16 bits wide. Add new functions to properly handle 16-bit brightness in big endian, since the two 8- and 16-bit cases are distinct from each other.

2023-01-18drm/amd/display: fix issues with driver unloadHamza Mahfooz
Currently, we run into a number of WARN()s when attempting to unload the amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from calling drm_encoder_cleanup() too early. So, to fix this we can stop calling drm_encoder_cleanup() from amdgpu_dm_fini() and instead have it be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly allocated by the slab allocator.
