Bug ID: 290326
Summary: amdgpu: Unimplemented ...get_mclk.. and ...get_sclk...
raise kernel messages
Product: Ports & Packages
Version: Latest
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: Individual Port(s)
Assignee: ports-bugs@FreeBSD.org
Reporter: jeff+freebsd@wagsky.com
It is not uncommon for monitoring programs to call `sysctl -a` if multiple
values are needed. After installing the DRM drivers for AMD through FreeBSD pkg
repo, messages began appearing on the console as well as in the logs every
minute, coincident with the cron job doing the monitoring
info: kernel: amdgpu: pp_dpm_get_mclk_od was not implemented.
info: kernel: amdgpu: pp_dpm_get_sclk_od was not implemented.
After removing `sysctl -a` from that job and hard-coding the sysctls to be
retrieved, the messages stopped.
Further examination indicated that the following two sysctls trigger the
messages:
sys.device.drmn0.pp_mclk_od
sys.device.drmn0.pp_sclk_od]
