Aldebaran has fine grained DPM for GFXCLK. Instead of a discrete level, user can specify a min/max range of GFXCLK for any profiling/tuning purpose.This option is available only in manual performance level mode. Select "manual" as power_dpm_force_performance_level and specify the min/max range using pp_dpm_sclk sysfs node. User cannot specify a min/max range outside of the default min/max range of the ASIC. If specified outside the range, values will be bound by the default min/max range. Ex: To use gfxclk min = 600MHz and max = 900MHz echo manual > /sys/bus/pci/devices/.../power_dpm_force_performance_level echo min 600 max 900 > /sys/bus/pci/devices/.../pp_dpm_sclk 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.
