Bug ID: 86566
Summary: [NV96] nouveau_pmops_suspend returns -16
Product: xorg
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau

dmesg with noaccel=1 config=NvForcePost=1
Hardware:
* 9600M GT (NV96)
* 9400M (NVAC)
Tested on
http://cgit.freedesktop.org/~darktama/nouveau/commit/?id=8c83f75747abb996509d01d30104fe820eae9d67
The NV96 card fails to suspend, with nouveau_pmops_suspend returning -16.
PDISPLAY.CHANNEL[0].STAT (0x610200) value is not the one expected after the
channel deactivation (see nv50_disp_core_fini in core/engine/disp/nv50.c).
I compared mmiotraces from Nouveau and the blob. 0x610200 default values differ
greatly - for Nouveau: 0x0d050029, for Nvidia: 0x48000008 - if
config=NvForcePost=1 isn't given (the blob is running it by default, not
Nouveau); adding ForcePost doesn't help. There are some differences in SOR and
PIOR caps but getting them to match the blob ones doesn't help.
