}
Due to calling "drm_fb_helper_fini" however, "dev->fb_helper" will be NULL and
thus this function does nothing on the error path.
So in summary, "drm_fb_helper_fbdev_setup" calls the driver callback
drm_fb_helper_funcs::fb_p
0x18/0x40
This can be reproduced with QEMU and CONFIG_FB_LITTLE_ENDIAN=n.

Yes I suspect there is an ACPI and/ or PCI problem, possibly
te, not use
the suspend functionality of bbswitch, if you load bbswitch without
module options amd do not write to /proc/bbswitch, then it allows you to
read out the actual status (you could also just use lspci -H1 for that
though).

Checking for _PR3 was the intention, but it seems that the ACPI core
does not really store it somewhere. Your check should be simple enough,
I'll use that in the next version.
Do you have any suggestions for the case where the pcieport driver
refuses to put the bridge in D3 (because the BIOS is too old)? In that
case the nouveau driver needs to fallback to the DSM method (but not
when runtime PM is deliberately disabled by writing control=on).

The first parameter for CreateField is evaluated as buffer (sec 19.6.21).
According to 19.3.5.6 (Data Types and Type Conversions) an implicit
conversion to a Buffer is only possible from an Integer and String, a
Package does not belong to the possibilities.
Note that the return value may be an integer for unsupported revision
IDs or UUIDs (like 0x8002). These should be compatible with Buffers
though as stated above and acpi_check_dsm() can handle that case, but
unfortunately sets a Package as fourth argument and can therefore not be
used in nouveau.

Hi,
While trying PRIME, I got a lockdep warning after exiting glxgears. Is
it harmful? The command was:
DRI_PRIME=1 glxgears
Offload provider is a GT425M (NVC0), output sink is an Intel i5-460M.
Kind regards,
Peter
