This patch enables editing sysfs file power_dpm_force_performance_level for yellow carp. User could thus adjust the dpm forced level. v2: enable fine grain control of GFXCLK only when in manual performance level mode. In other mode, the min/max range of GFXCLK will be reset to corresponding values. Ex: To enable min 300MHz / max 600MHz gfx clocks 1) echo manual > /sys/bus/pci/devices/.../power_dpm_force_performance_level 2) echo s 0 300 > /sys/bus/pci/devices/.../pp_od_clk_voltage 3) echo s 1 600 > /sys/bus/pci/devices/.../pp_od_clk_voltage 4) echo c > /sys/bus/pci/devices/.../pp_od_clk_voltage Signed-off-by: Xiaomeng Hou <Xiaomeng.Hou@amd.com> Acked-by: Huang Rui <ray.huang@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.
