mainlining shenanigans
Use pp_od_clk_voltage node to enable performance determinism and GFX clock min/max range for aldebaran. This is to avoid overload of pp_dpm_sclk and maintain consistency in user lib interfaces. Ex: To enable perf determinism at 900MHz max gfx clock 1) echo perf_determinism > /sys/bus/pci/devices/.../power_dpm_force_performance_level 2) echo s 1 900 > /sys/bus/pci/devices/.../pp_od_clk_voltage 3) echo c > /sys/bus/pci/devices/.../pp_od_clk_voltage Ex: To enable min 500MHz/max 900MHz gfx clocks 1) echo manual > "/sys/bus/pci/devices/.../power_dpm_force_performance_level" 2) echo s 0 500 > "/sys/bus/pci/devices/.../pp_od_clk_voltage" 3) echo s 1 900 > "/sys/bus/pci/devices/.../pp_od_clk_voltage” 4) echo c > "/sys/bus/pci/devices/.../pp_od_clk_voltage” Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@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.
