--- Comment #8 from Matti Rintala <mrintal...@gmail.com> --- Here's what /sys/class/drm/card* show when only AMD iGPU is enabled (prime-select amd): /sys/class/drm/card0: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0 /sys/class/drm/card0-DP-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-DP-1 /sys/class/drm/card0-eDP-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-eDP-1 /sys/class/drm/card0-HDMI-A-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-HDMI-A-1 (/sys/class/drm/card0/device/vendor is 0x1002) Here's the same when Nvidia dGPU is enabled for offload use (prime-select offload): /sys/class/drm/card0: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0 /sys/class/drm/card0-DP-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-DP-1 /sys/class/drm/card0-eDP-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-eDP-1 /sys/class/drm/card0-HDMI-A-1: symbolic link to ../../devices/pci0000:00/0000:00:08.1/0000:05:00.0/drm/card0/card0-HDMI-A-1 /sys/class/drm/card1: symbolic link to ../../devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card1 (/sys/class/drm/card0/device/vendor is still 0x1002, /sys/class/drm/card1/device/vendor is 0x10de) So, only /sys/class/drm/card1 was added. However, System-monitor-amd.png is a screenshot snippet showing System monitor when only AMD iGPU is enabled (I've added it to show GPU1 max RAM, which I've limited to 512 MB for the iGPU). Then, when I just run enable the Nvidia dGPU (run "prime-select offload") and log out and in again, System-monitor-offload1.png snippet shows that now System monitor's GPU1 max RAM is 4 GB (which is what the Nvidia dGPU has). And adding GPU2, System-monitor-offload2.png shows that GPU2 max RAM is the iGPU's 512 MB. -- You are receiving this mail because: You are watching all bug changes.
