https://bugzilla.kernel.org/show_bug.cgi?id=115321 Bug ID: 115321 Summary: radeon runpm falsely disabled on Clevo P170EM Product: Drivers Version: 2.5 Kernel Version: 4.6-rc1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: haagch.christoph@xxxxxxxxxxxxxx Regression: No Created attachment 210811 --> https://bugzilla.kernel.org/attachment.cgi?id=210811&action=edit dmesg Commit e64c952efb8e0c15ae82cec8e455ab4910690ef1 disables runpm when "laptops don't provide an ACPI method to control dGPU power". Up to now, runpm worked fine for me, but this commit disabled it also for me. There are some ACPI errors that maybe have something to do with it: [ 3.245994] vga_switcheroo: enabled [ 3.246040] ATPX version 1, functions 0x00000033 [ 3.278214] ACPI Error: Field [TMPB] at 294912 exceeds Buffer [ROM1] size 262144 (bits) (20160108/dsopcode-236) [ 3.278218] ACPI Error: Method parse/execution failed [\_SB.PCI0.GFX0.ATRM] (Node ffff88080e8daa50), AE_AML_BUFFER_LIMIT (20160108/psparse-542) [ 3.278224] failed to evaluate ATRM got AE_AML_BUFFER_LIMIT Full 4.6-rc1 dmesg is attached. Meanwhile I changed this function: bool radeon_has_atpx_dgpu_power_cntl(void) { return true; //radeon_atpx_priv.atpx.functions.power_cntl; } and runpm works again. The uvd and vce errors seen in the dmesg also vanished after this change and a reboot. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
