Nouveau - Nov 2019 - nouveau on NV04 calling illegal method 02fc under fbcon

Hi,

Trying a new kernel on old [NV04] system I get tons of 
  nouveau 0000:01:00.0: gr: intr 00000001 [NOTIFY] nsource 00000040
    [ILLEGAL_MTHD] nstatus 00004000 [PROTECTION_FAULT] ch 0
    [DRM] subc 3 class 004a mthd 02fc data 00000003
errors when operating on console.

As I updated from 4.3 kernel, a bisect does not feel like the best start.

What is that 02fc method which fbcon is probably triggering as
hardware-acceleration on nouveau side.

Thanks,
Bruno

The bigger your upgrade, the more efficient bisecting actually is. The
difference between one kernel (usually 12-13 bisects) and 20 kernels

Well with the time it takes to compile the kernel (and worse the Kconfig
changing quite a lot between the endpoints) it's not fun at all.

Thus I will first try with reverting below few commits.

I will try out when I am back next to that machine.

If it's fbcon acceleration (which I assume as output to fbcon causes
new errors), probably one of the few commits to
drivers/gpu/drm/nouveau/nv04_fbcon.c would be the cause:

  1167c6bc51880cb74a3b1a02286fc25392684281
    drm/nouveau: allocate device object for every client
  9dec9280523157da820f923e18dd6a7bf99fead7
    drm/nouveau/fbcon: make use of drm_fb_helper.dev
  28668f43b8e421634e1623f72a879812288dd06b
    drm/nouveau/fbcon: fix font width not divisible by 8
  f045f459d925138fe7d6193a8c86406bda7e49da
    drm/nouveau/fbcon: fix out-of-bounds memory accesses
  4dc28134a8c124aa01b441e1e5b8b54312edc5dd
    drm/nouveau: rename nouveau_drm.h to nouveau_drv.h

At first glance I would suspect one of:
  28668f43b8e421634e1623f72a879812288dd06b
  f045f459d925138fe7d6193a8c86406bda7e49da
