Performance Determinism is a new mode in Aldebaran where PMFW tries to maintain sustained performance level. It can be enabled on a per-die basis on aldebaran. To guarantee that it remains within the power cap, a max GFX frequency needs to be specified in this mode. A new power_dpm_force_performance_level, "perf_determinism", is defined to enable this mode in amdgpu. The max frequency (in MHz) can be specified through pp_dpm_sclk. The mode will be disabled once any other performance level is chosen. Ex: To enable perf determinism at 900Mhz max gfx clock echo perf_determinism > /sys/bus/pci/devices/.../power_dpm_force_performance_level echo max 900 > /sys/bus/pci/devices/.../pp_dpm_sclk Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Kenneth Feng <kenneth.feng@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.
