Bug ID: 102800 Summary: DRI_PRIME regression- radeon: Failed to allocate virtual address for buffer Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: higuita@gmx.net

Using a ubuntu 17.04 with a kernel 4.13.2, mesa 1.3-git and libdrm 2.4.83 on a lenovo thinkpad S440 with a intel haswell and a radeon HD8670M/8690M

doing this commands i get a error:

In the dmesg, i can see this:

All this setup worked fine in a previous kernel versions, IIRC, 4.11 and below and started to fail in 4.12 and above

I also notice that the dedicated card switch fron DynOff to DynPwr in /sys/kernel/debug/vgaswitcheroo/switch for a few seconds when trying to run the glxgears

Finally, If i boot the system with radeon.runpm=1, it works

Let me know if you need more logs
