Following warning is found when using W=1 to build kernel:
In function ‘nvkm_udevice_info’,
inlined from ‘nvkm_udevice_mthd’ at drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:195:10:
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:164:2: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation]
164 | strncpy(args->v0.chip, device->chip->name, sizeof(args->v0.chip));
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:165:2: warning: ‘strncpy’ specified bound 64 equals destination size [-Wstringop-truncation]
165 | strncpy(args->v0.name, device->name, sizeof(args->v0.name));
The reason of this warning is strncpy() does not guarantee that the
destination buffer will be NUL terminated. If the length of source string
is bigger than number we set by third input parameter, only a part of
characters is copied to the destination, and no NUL-terminated string is
automatically added. There are some potential risks.
So use snprintf() to replace strncpy().

The code which constructs the modules for each engine present on the GPU
passes -1 for 'instance' on non-instanced engines, which affects how the
name for a sub-device is generated. This is then stored as 'instance 0'
in nvkm_subdev.inst, so code can potentially be shared with earlier GPUs
that only had a single instance of an engine.
However, GF100's CE constructor uses this value to calculate the address
of its falcon before it's translated, resulting in CE0 getting the wrong
address.
This slightly modifies the approach, always passing a valid instance for
engines that *can* have multiple copies, and having the code for earlier
GPUs explicitly ask for non-instanced name generation.

We don't currently have any kind of real acceleration on Ampere GPUs,
but the TTM memcpy() fallback paths aren't really designed to handle
copies between different devices, such as on Optimus systems, and
result in a kernel OOPS.
A few options were investigated to try and fix this, but didn't work
out, and likely would have resulted in a very unpleasant experience
for users anyway.
This commit adds just enough support for setting up a single channel
connected to a copy engine, which the kernel can use to accelerate
the buffer copies between devices. Userspace has no access to this
incomplete channel support, but it's suitable for TTM's needs.
A more complete implementation of host(fifo) for Ampere GPUs is in
the works, but the required changes are far too invasive that they
would be unsuitable to backport to fix this issue on current kernels.

The code builds on most architectures, but fails on parisc where ENOSYS
is defined as 251.
Replace the error code with -ENODEV (-19). The actual error code does
not really matter and is not passed to userspace - it just has to be
negative.

Long ago, there had been plans for making use of a bunch of these APIs
from userspace and there's various checks in place to stop misbehaving.
Countless other projects have occurred in the meantime, and the pieces
didn't finish falling into place for that to happen.
They will (hopefully) in the not-too-distant future, but it won't look
quite as insane. The super checks are causing problems right now, and
are going to be removed.
