Hi,
This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used
to help read/write registers with critical time limitation, such as
updating display configuration during the vblank. It controls Global
Command Engine (GCE) hardware to achieve this requirement.
These patches have a build dependency on top of v4.6-rc1.
Changes since v5:
- keep order of display tasks
- use list instead of arrary for thread's tasks management
- remove task_active_list
- prevent deadlock in suspend/resume flow
- prevent to flush in both suspending and suspended
- prevent to add auto release work after suspending or suspended
- merge cmdq_task_create() into cmdq_task_acquire()
- remove cmdq_task_free_command_buffer() and call dma_free_coherent()
directly
Best regards,
HS Liao
