https://bugzilla.suse.com/show_bug.cgi?id=1185174 https://bugzilla.suse.com/show_bug.cgi?id=1185174#c8 --- Comment #8 from Takashi Iwai --- OK, thanks, then it's just the missing CONFIG_DRM_LEGACY that was introduced since 5.11. The exposure of agpgart frontend was disabled without this. But, as this is marked as "DANGEROUS" in Kconfig menuconfig DRM_LEGACY bool "Enable legacy drivers (DANGEROUS)" depends on DRM && MMU help Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous APIs to user-space, which can be used to circumvent access restrictions and other security measures. For backwards compatibility those drivers are still available, but their use is highly inadvisable and might harm your system. You are recommended to use the safe modeset-only drivers instead, and perform 3D emulation in user-space. Unless you have strong reasons to go rogue, say "N". So, as already expected, this bug is likely WONTFIX. -- You are receiving this mail because: You are the assignee for the bug.
