Seems I have been able to push:
unneeded info looks like this:
[ 338.951804] nouveau: DRM-master:00000000:8000900b: fini completed in 7us
[ 338.951811] nouveau: DRM-master:00000000:8000900b: destroy children...
[ 338.951818] nouveau: DRM-master:00000000:8000900b: destroy running...
[ 338.951825] nouveau: DRM-master:00000000:8000900b: destroy completed in
6us...
[ 338.954303] nouveau: DRM-master:00000000:8000900b: init running...
to trace level... making nouveau.debug=debug more clear.
I have found the macros that do these messages in
drivers/gpu/drm/nouveau/include/nvkm/core/client.h :
/* logging for client-facing objects */
#define nvif_printk(o,l,p,f,a...) do { \
const struct nvkm_object *_object = (o); \
const struct nvkm_client *_client = _object->client; \
if (_client->debug >= NV_DBG_##l) \
printk(KERN_##p "nouveau: %s:%08x:%08x: "f, _client->name, \
_object->handle, _object->oclass, ##a); \
} while(0)
#define nvif_fatal(o,f,a...) nvif_printk((o), FATAL, CRIT, f, ##a)
#define nvif_error(o,f,a...) nvif_printk((o), ERROR, ERR, f, ##a)
#define nvif_debug(o,f,a...) nvif_printk((o), DEBUG, INFO, f, ##a)
#define nvif_trace(o,f,a...) nvif_printk((o), TRACE, INFO, f, ##a)
#define nvif_info(o,f,a...) nvif_printk((o), INFO, INFO, f, ##a)
#define nvif_ioctl(o,f,a...) nvif_trace((o), "ioctl: "f, ##a)
#endif
So all I done was:
sed -i 's/nvif_debug/nvif_trace/g' drivers/gpu/drm/nouveau/nvkm/core/object.c
resulting in a "patch":

Now need to work on removing also the:
