Starting with Vega the hardware supports concurrent flushes of VMID which can be used to implement per process VMID allocation. But concurrent flushes are mutual exclusive with back to back VMID allocations, fix this to avoid a VMID used in two ways at the same time. v2: don't set ring to NULL Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: James Zhu <James.Zhu@amd.com> Tested-by: James Zhu <James.Zhu@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.
