scratch_reg0 is used by RLCG for register access usage in SRIOV case. both CP firmware and driver can invoke RLCG to do certain register access (through scratch_reg0/1/2/3) but rlcg now dosen't have race concern so if two clients are in parallel doing the RLCG reg access then we are colliding, GFX IB test is a runtime work, so it is forbidden to use scrach_reg0/1/2/3 during IB test period note: Although we can only have this change for SRIOV, but looks it doesn't worth the effort to differentiate bare-metal with SRIOV on the GFX ib test Signed-off-by: Monk Liu <Monk.Liu@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.
