Bug ID: 112071
Summary: 5700 XT: ppfeaturemask doesn't work with iGPU
multi-monitor
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: minor
Priority: not set
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: zamundaaalp@gmail.com
If the BIOS option "iGPU multi-monitor" is enabled (so I can use the internal
GPU ports, namely DVI) amdgpu.ppfeaturemask doesn't do anything anymore.
"cat /sys/module/amdgpu/parameters/ppfeaturemask" gives the mask I set (either
fffd7fff or simply 0xffffffff) but the files like
/sys/class/drm/card0/device/pp_od_clk_voltage don't actually get created. They
do if I disable iGPU multi-monitor.
Wether I'm on kernel 5.3.6 or 5.4rc2 doesn't matter, wether I'm on Mesa 19.2 or
19.3 (git) doesn't matter as well.
