Hello, I have an asus UX32VD, with a GT610M inside, which works with the Optimus architecture, handle by PRIME. The bug is currently with the kernel 5.2.0, but it have always been like that as far as I remember. uname -a : Linux ga-laptop 5.2.0-arch2-1-ARCH #1 SMP PREEMPT Mon Jul 8 18:18:54 UTC 2019 x86_64 GNU/Linux lspci : 01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1) While it is not in use, nouveau shutdown the chipset as expected : cat /sys/kernel/debug/dri/1/pstate 07: core 270 MHz memory 405 MHz 0f: core 625 MHz memory 900 MHz DC: core 0 MHz memory 0 MHz While an app is launched with DRI_PRIME=1, we can see that the chipset is set to 07 : DRI_PRIME=1 glxgears & cat /sys/kernel/debug/dri/1/pstate 07: core 270 MHz memory 405 MHz 0f: core 625 MHz memory 900 MHz DC: core 270 MHz memory 324 MHz But when I tried to reclock, I have an error : echo 0f > /sys/kernel/debug/dri/1/pstate -bash: echo: write error: Function not implemented And I have this in dmesg: [ 351.283183] nouveau 0000:01:00.0: bus: MMIO write of ffff8c1f FAULT at 6013d4 [ IBUS ] [ 458.362570] nouveau 0000:01:00.0: bus: MMIO write of 0000001f FAULT at 6013d4 [ IBUS ] Thanks
we don't support reclocking on fermi GPUs yet. And yours is a GF117. There has some work be done towards this but progress is rather slow. There might be some branches you can try out, but I don't know the details. Best would be to join #nouveau on freenode and ask skeggsb or RSpliet. Closing now as there isn't anything we can do right now besides implementing this feature. Sorry.
I am sorry, I was sure it was a Kepler GPU, I don't why. Thank you for your response and your work anyway !
