| 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.
