Add helper function in order to remove RREG32/WREG32 in current pcie_rreg/wreg function for soc15 and onwards adapters. PCIE_INDEX/DATA pairs are used to access regsiters outside of mmio bar in the helper functions. The new helper functions help remove the recursion of amdgpu_mm_rreg/wreg from pcie_rreg/wreg and provide the oppotunity to centralize direct and indirect access in a single function. v2: Fixed typo and refine the comments v3: Remove unnecessary volatile local variable Signed-off-by: Hawking Zhang <Hawking.Zhang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Kevin Wang <kevin1.wang@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Reviewed-by: Guchun Chen <guchun.chen@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.
