what: the MQD's save and restore of KCQ (kernel compute queue) cost lots of clocks during world switch which impacts a lot to multi-VF performance how: introduce a paramter to control the number of KCQ to avoid performance drop if there is no kernel compute queue needed notes: this paramter only affects gfx 8/9/10 v2: refine namings v3: choose queues for each ring to that try best to cross pipes evenly. v4: fix indentation some cleanupsin the gfx_compute_queue_acquire() v5: further fix on indentations more cleanupsin gfx_compute_queue_acquire() TODO: in the future we will let hypervisor driver to set this paramter automatically thus no need for user to configure it through modprobe in virtual machine Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
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.
