This commit adds support for the GB20x GPUs found on GeForce RTX 50xx
series boards.
Beyond a few miscellaneous register moves and HW class ID plumbing,
this reuses most of the code added to support GH100/GB10x.

This commit enables basic support for Hopper GPUs, and is intended
primarily as a base supporting Blackwell GPUs, which reuse most of
the code added here.
Advanced features such as Confidential Compute are not supported.
Beyond a few miscellaneous register moves and HW class ID plumbing,
the bulk of the changes implemented here are to support the GSP-RM
boot sequence used on Hopper/Blackwell GPUs, as well as a new page
table layout.
There should be no changes here that impact prior GPUs.

The current code using NV90F1_CTRL_CMD_VASPACE_COPY_SERVER_RESERVED_PDES
not only requires changes to support the new page table layout used on
Hopper/Blackwell GPUs, but is also broken in that it always mirrors the
PDEs used for virtual address 0, rather than the area reserved for RM.
This works fine for the non-NVK case where the kernel has full control
of the VMM layout and things end up in the right place, but NVK puts
its kernel reserved area much higher in the address space.
Fixing the code to work at any VA is not enough as some parts of RM want
the reserved area in a specific location, and NVK would then hit other
assertions in RM instead.
Fortunately, it appears that RM never needs to allocate anything within
its reserved area for DRM clients, and the COPY_SERVER_RESERVED_PDES
control call primarily serves to allow RM to locate the root page table
when initialising a channel's instance block.
Flag VMMs allocated by the DRM driver as externally owned, and use
NV0080_CTRL_CMD_DMA_SET_PAGE_DIRECTORY to inform RM of the root page
table in a similar way to NVIDIA's UVM driver.
The COPY_SERVER_RESERVED_PDES paths are kept for the golden context
image and gr scrubber channel, where RM needs the reserved area.

With GSP-RM handling the majority of the HW programming, NVKM's usual
HALs are more elaborate than necessary, resulting in a fair amount of
duplicated boilerplate.
Adds 'nvkm_rm_gpu' which serves to provide GPU-specific constants and
functions in a more streamlined manner.
This is initially used in subsequent commits to store engine class IDs,
and replace the per-engine/engobj boilerplate with common code for all
GSP-RM supported engines - and is further extended when adding GH100,
GB10x and GB20x support.

Later patches in the series add HALs around various RM APIs in order to
support a newer version of GSP-RM firmware. In order to do this, begin
by splitting the code up into "modules" that roughly represent RM's API
boundaries so they can be more easily managed.

Some GSP RPC commands need a new reply policy: "caller don't care about
the message content but want to make sure a reply is received". To
support this case, a new reply policy is introduced.
NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY is a large GSP RPC command. The actual
required policy is NVKM_GSP_RPC_REPLY_POLL. This can be observed from the
dump of the GSP message queue. After the large GSP RPC command is issued,
GSP will write only an empty RPC header in the queue as the reply.
Without this change, the policy "receiving the entire message" is used
for NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY. This causes the timeout of receiving
the returned GSP message in the suspend/resume path.
Introduce the new reply policy NVKM_GSP_RPC_REPLY_POLL, which waits for
the returned GSP message but discards it for the caller. Use the new policy
NVKM_GSP_RPC_REPLY_POLL on the GSP RPC command
NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY.

There can be multiple cases of handling the GSP RPC messages, which are
the reply of GSP RPC commands according to the requirement of the
callers and the nature of the GSP RPC commands.
The current supported reply policies are "callers don't care" and "receive
the entire message" according to the requirement of the callers. To
introduce a new policy, factor out the current RPC command reply polices.
Also, centralize the handling of the reply in a single function.
Factor out NVKM_GSP_RPC_REPLY_NOWAIT as "callers don't care" and
NVKM_GSP_RPC_REPLY_RECV as "receive the entire message". Introduce a
kernel doc to document the policies. Factor out
r535_gsp_rpc_handle_reply().
No functional change is intended for small GSP RPC commands. For large GSP
commands, the caller decides the policy of how to handle the returned GSP
RPC message.

The LOGINIT, LOGINTR, LOGRM, and LOGPMU buffers are circular buffers
that have printf-like logs from GSP-RM and PMU encoded in them.
LOGINIT, LOGINTR, and LOGRM are allocated by Nouveau and their DMA
addresses are passed to GSP-RM during initialization. The buffers are
required for GSP-RM to initialize properly.
LOGPMU is also allocated by Nouveau, but its contents are updated
when Nouveau receives an NV_VGPU_MSG_EVENT_UCODE_LIBOS_PRINT RPC from
GSP-RM. Nouveau then copies the RPC to the buffer.
The messages are encoded as an array of variable-length structures that
contain the parameters to an NV_PRINTF call. The format string and
parameter count are stored in a special ELF image that contains only
logging strings. This image is not currently shipped with the Nvidia
driver.
There are two methods to extract the logs.
OpenRM tries to load the logging ELF, and if present, parses the log
buffers in real time and outputs the strings to the kernel console.
Alternatively, and this is the method used by this patch, the buffers
can be exposed to user space, and a user-space tool (along with the
logging ELF image) can parse the buffer and dump the logs.
This method has the advantage that it allows the buffers to be parsed
even when the logging ELF file is not available to the user. However,
it has the disadvantage the debugfs entries need to remain until the
driver is unloaded.
The buffers are exposed via debugfs. If GSP-RM fails to initialize, then
Nouveau immediately shuts down the GSP interface. This would normally
also deallocate the logging buffers, thereby preventing the user from
capturing the debug logs.
To avoid this, introduce the keep-gsp-logging command line parameter. If
specified, and if at least one logging buffer has content, then Nouveau
will migrate these buffers into new debugfs entries that are retained
until the driver unloads.
An end-user can capture the logs using the following commands:
cp /sys/kernel/debug/nouveau/<path>/loginit loginit
cp /sys/kernel/debug/nouveau/<path>/logrm logrm
cp /sys/kernel/debug/nouveau/<path>/logintr logintr
cp /sys/kernel/debug/nouveau/<path>/logpmu logpmu
where (for a PCI device) <path> is the PCI ID of the GPU (e.g.
0000:65:00.0).
Since LOGPMU is not needed for normal GSP-RM operation, it is only
created if debugfs is available. Otherwise, the
NV_VGPU_MSG_EVENT_UCODE_LIBOS_PRINT RPCs are ignored.
A simple way to test the buffer migration feature is to have
nvkm_gsp_init() return an error code.

Currently we allocate all 3 levels of radix3 page tables using
nvkm_gsp_mem_ctor(), which uses dma_alloc_coherent() for allocating all of
the relevant memory. This can end up failing in scenarios where the system
has very high memory fragmentation, and we can't find enough contiguous
memory to allocate level 2 of the page table.
Currently, this can result in runtime PM issues on systems where memory
fragmentation is high - as we'll fail to allocate the page table for our

Luckily, we don't actually need to allocate coherent memory for the page
table thanks to being able to pass the GPU a radix3 page table for
suspend/resume data. So, let's rewrite nvkm_gsp_radix3_sg() to use the sg
allocator for level 2. We continue using coherent allocations for lvl0 and
1, since they only take a single page.

Add the NVreg_RegistryDwords command line parameter, which allows
specifying additional registry keys to be sent to GSP-RM. This
allows additional configuration, debugging, and experimentation
with GSP-RM, which uses these keys to alter its behavior.
Note that these keys are passed as-is to GSP-RM, and Nouveau does
not parse them. This is in contrast to the Nvidia driver, which may
parse some of the keys to configure some functionality in concert with
GSP-RM. Therefore, any keys which also require action by the driver
may not function correctly when passed by Nouveau. Caveat emptor.
The name and format of NVreg_RegistryDwords is the same as used by
the Nvidia driver, to maintain compatibility.

Nouveau manages GSP-RM DMA buffers with nvkm_gsp_mem objects. Several of
these buffers are never dealloced. Some of them can be deallocated
right after GSP-RM is initialized, but the rest need to stay until the
driver unloads.
Also futher bullet-proof these objects by poisoning the buffer and
clearing the nvkm_gsp_mem object when it is deallocated. Poisoning
the buffer should trigger an error (or crash) from GSP-RM if it tries
to access the buffer after we've deallocated it, because we were wrong
about when it is safe to deallocate.
Finally, change the mem->size field to a size_t because that's the same
type that dma_alloc_coherent expects.

The new VM_BIND UAPI uses the DRM GPU VA manager to manage the VA space.
Hence, we a need a way to manipulate the MMUs page tables without going
through the internal range allocator implemented by nvkm/vmm.
This patch adds a raw interface for nvkm/vmm to pass the resposibility
for managing the address space and the corresponding map/unmap/sparse
operations to the upper layers.

This was completely bogus before, using maximum DCB device index rather
than maximum AUX ID to size the buffer that stores event refcounts.
*Pretty* unlikely to have been an actual problem on most configurations,
that is, unless you've got one of the rare boards that have off-chip DP.
There, it'll likely crash.

During system shutdown nouveau might not be able to request firmware from
Userspace, which then leads to a regression preventing the system from
shutting down.
Cache the scrubber binary for this case.

Turing apparently needs to use the same register we use on Ampere.
Not executing the scrubber ucode when required would result in large
areas of VRAM being inaccessible to the driver.
