accel/ivpu: Add initial support for VPU 4

2023-08-09T11:55:21Z

Add support VPU 4 - new generation of VPU IP with various hardware design improvements. From driver point of view, it differs in register set, initialization process and MMU memory ranges.

accel/ivpu: Rename sources to use generation based names

2023-08-09T11:39:52Z

Given that VPU generation can be used by multiple platforms, driver should use VPU IP generation in names instead of a platform. Change naming for sources files. Use 37XX format, where: 3 - major VPU IP generation version 7 - minor VPU IP generation version XX - postfix indicating this is an architecture and not marketing name Signed-off-by: Jacek Lawrynowicz Reviewed-by: Stanislaw Gruszka Signed-off-by: Stanislaw Gruszka Reviewed-by: Jeffrey Hugo Link: https://patchwork.freedesktop.org/patch/msgid/20230731161258.2987564-2-stanislaw.gruszka@linux.intel.com

accel/ivpu: Add command buffer submission logic

2023-01-19T10:12:00Z

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.

accel/ivpu: Add GEM buffer object management

2023-01-19T10:11:34Z

Adds four types of GEM-based BOs for the VPU: - shmem - internal - prime All types are implemented as struct ivpu_bo, based on struct drm_gem_object. VPU address is allocated when buffer is created except for imported prime buffers that allocate it in BO_INFO IOCTL due to missing file_priv arg in gem_prime_import callback. Internal buffers are pinned on creation, the rest of buffers types can be pinned on demand (in SUBMIT IOCTL). Buffer VPU address, allocated pages and mappings are released when the buffer is destroyed. Eviction mechanism is planned for future versions.
