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. This patch is has two main files: - ivpu_mmu_context.c handles MMU page tables and memory mapping - ivpu_mmu.c implements a driver that programs the MMU device Co-developed-by:

VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. The VPU device consist of following components: - Buttress - provides CPU to VPU integration, interrupt, frequency and power management. - Memory Management Unit (based on ARM MMU-600) - translates VPU to host DMA addresses, isolates user workloads. - RISC based microcontroller - executes firmware that provides job execution API for the kernel-mode driver - Neural Compute Subsystem (NCS) - does the actual work, provides Compute and Copy engines. - Network on Chip (NoC) - network fabric connecting all the components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client CPUs (14th generation). Module sources are at drivers/accel/ivpu and module name is "intel_vpu.ko". This patch includes only very besic functionality: - module, PCI device and IRQ initialization - register definitions and low level register manipulation functions - SET/GET_PARAM ioctls - power up without firmware Co-developed-by: -

Add a helper for skipping the HDMI VSDB audio latency fields. There's a functional change for HDMI VSDB blocks that do not respect the spec: "I_Latency_Fields_Present shall be zero if Latency_Fields_Present is zero". We assume this to hold when skipping the latency fields, and ignore non-zero I_Latency_Fields_Present if Latency_Fields_Present is zero.

Now that we have pre-parsed CTA VDB VICs stored in info->vics, leverage that to simplify CTA Y420CMDB parsing. Move updating the y420_cmdb_modes bitmap to the display info parsing stage, instead of updating it during add modes. This allows us to drop the intermediate y420_cmdb_map from display info, and replace it with a local variable. This is prerequisite work for overall better separation of the two parsing steps (updating display info and adding modes). Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

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.

Now that we have all the VICs in info->vics, use them to simplify access based on VIC index, i.e. on the order of VICs in the EDID, and avoid passing CTA VDB pointers around. This also fixes the highly unlikely scenarios of a) multiple HDMI VSDBs, and b) HDMI VSDB 3D modes using VIC indexes that span across multiple CTA VDBs, and the combination of the two.

A number of places need access to the VICs. Just parse them early for easy access. Gracefully handle multiple CTA VDBs. It's unlikely to have more than one, but the CTA-861 references "Video Data Block(s)", so err on the safe side. Start parsing them now, convert users in follow-up to have fewer moving parts in one go. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Commit 537d9ed2 ("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.

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. Reported-by:

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.
