There is an issue that CP will check the HIQ queue to be configured and mapped with KIQ ring, otherwise, it will be unable to read back the secure buffer while the gfxoff is enabled even with trusted IP blocks. v1 -> v2: - Fix to remove surplus set_resources packets. - Fill the whole configuration in MQD. - Change the author as Aaron because he addressed the key point of this issue. - Add kiq ring lock. v2 -> v3: - Free the lock while in error return case. - Remove the programming only needed by the queue is unmapped. v3 -> v4: - Remove doorbell programming because it's used for restarting queue. - Remove CP scheduler programming because map_queue packet will handle this. v4 -> v5: - Remove cp_hqd_active because mec ucode will enable it while use map_queues. - Revise goto out_unlock. - Correct the right doorbell offset for HIQ that kfd driver assigned in the packet. v5 -> v6: - Merge Arcturus fix into this patch because it will get oops in Arcturus platform.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
