On MTL, for obvious reasons, HuC is only available on the media tile.
We already disable SW support for HuC on the root gt due to the
absence of VCS engines, but we also need to update the getparam to point
to the HuC struct in the media GT.

Before we add the second step of the MTL HuC auth (via GSC), we need to
have the ability to differentiate between them. To do so, the huc
authentication check is duplicated for GuC and GSC auth, with meu
binaries being considered fully authenticated only after the GSC auth
step.
To report the diff
In the previous patch we extracted the offset of the legacy-style HuC
binary located within the GSC-enabled blob, so now we can use that to
load the HuC via DMA if the fuse is set that way.
Note that we now need to differentiate between "GSC-enabled binary" and
"loaded by GSC", so the former case h
The full authentication via the GSC requires an heci packet submission

types.

Now that each FW has its own reserved area, we can keep them always

The HuC loading and authentication flow is once again changing and a new

The new binaries that support the 2-step authentication contain the

The GuC interface supports a mechanism for returning errors against
non-blocking H2G calls. This is called FAST_REQUEST. Given that the
call is asynchronous, matching the returned error up is difficult.
However, getting any error at all back is better than no error.

1ba6113a90a0 removed a lot of the kernel GPU channel, but method 0x128
was important as otherwise the GPU spams us with `CACHE_ERROR` messages.
We use the blit subchannel inside our vblank handling, so we should keep
at least this part.
v2: Only do it for NV11+ GPUs
Closes: https://gitlab.freede
Currently the driver passes the PINGPONG index to
dpu_hw_intf_ops::bind_pingpong_blk() callback and uses separate boolean
flag to tell whether INTF should be bound or unbound. Simplify this by
passing PINGPONG_NONE in case of unbinding and drop the flag completely.

Unfortunately with the patch applied to 6.3.4 it causes the old problem. The
screen stays dark, USB keyboard offline when trying to resume. So special
treatment is still required it seems.
