Bug ID: 104784
Summary: Unable to do reclocking manually
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau

Hi,
I have a laptop with Optimus technology, my Nvidia card is a GTX 640MX. I use
Debian Unstable x86_64 with nouveau 1.0.15 and Mesa 17.3.3
Unfortunatly, it's impossible to do reclocking with Nouveau and my GPU.
When i launch "cat /sys/kernel/debug/dri/1/pstate", i have these results :
07: core 270-405 MHz memory 648 MHz
0a: core 270-601 MHz memory 1600 MHz
0f: core 270-614 MHz memory 2800 MHz
AC: core 0 MHz memory 0 MHz
------
It's anormal to have these line "AC: core 0 MHz memory 0 MHz", right ?
Because when i set "echo 0f > /sys/kernel/debug/dri/1/pstate", the console (not
the system) hangs. And when i launch a game (Tyranny), it does not work.
