7df3d58750 gpu: nvgpu: add safe channel id lookup
Add gk20a_channel_from_id() to retrieve a channel, given a raw channel
ID, with a reference taken (or NULL if the channel was dead). This makes
it harder to mistakenly use a channel that's dead and thus uncovers bugs
sooner. Convert code to use the new lookup when applicable; work remains
to convert complex uses where a ref should have been taken but hasn't.

The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is
returned for such IDs. This is often useful and does not hurt when
unnecessary.

However, this does not prevent the case where a channel would be closed
and reopened again when someone would hold a stale channel number. In
all such conditions the caller should hold a reference already.

The only conditions where a channel can be safely looked up by an id and
used without taking a ref are when initializing or deinitializing the
list of channels.

MISRA rule 14.4 doesn't allow the usage of integer types as booleans
in the controlling expression of an if statement or an iteration
statement.

Fix violations where the result of a bitwise operation is used as
boolean in the controlling expression of if and loop statements.

Changed few enums into macros because they were used in bit-shift &
bitwise operations and MISRA rule 10.1 forbids the usage of signed
types in bit-shift & bitwise operations.

The BIOS_GET_FIELD() macro does a simple bit mask and shift operation.
The value of this macro is assigned to variables of different data
types. Casting the macro to different data types causes MISRA rule
10.8 violations. This issue is resolved by doing the cast inside the
macro and returning the value in the correct data type. These changes
also clear MISRA rule 10.1, 10.3 and 10.4 violations.

7225562936 gpu: nvgpu: Re-allocate PDs when they increase in size
The problem here, and the solution, requires some background
so let's start there.

During page table programming page directories (PDs) are
allocated as needed. Each PD can range in size, depending on
chip, from 256 bytes all the way up to 32KB (gk20a 2-level
page tables).

In HW, two distinct PTE sizes are supported: large and small.
The HW supports mixing these at will. The second to last level
PDE has pointers to both a small and large PD with
corresponding PTEs. Nvgpu doesn't handle that well and as a
result historically we split the GPU virtual address space
up into a small page region and a large page region. This
makes the GMMU programming logic easier since we now only have
to worry about one type of PD for any given region.

But this presents issues for CUDA and UVM. They want to be
able to mix PTE sizes in the same GPU virtual memory range.

In general we still don't support true dual page directories.
That is page directories with both the small and large next
level PD populated. However, we will allow adjecent PDs to
have different sized next-level PDs.

Each last level PD maps the same amount. On Pascal+ that's
2MB. This is true regardless of the PTE coverage (large or
small). That means the last level PD will be different in
size depending on the PTE size.

So - going back to the SW we allocate PDs as needed when
programming the page tables. When we do this allocation we
allocate just enough space for the PD to contain the
necessary number of PTEs for the page size. The problem
manifests when a PD flips in size from large to small PTEs.

Consider the following mapping operations:

  map(gpu_va -> phys) [large-pages]
  unmap(gpu_va)
  map(gpu_va -> phys) [small-pages]

In the first map/unmap we go and allocate all the necessary
PDs and PTEs to build this translation. We do so assuming a
large page size. When unmapping, as an optimzation/quirk of
nvgpu, we leave the PDs around. We know they may well be used
again in the future.

But if we swap the size of the mapping from large to small
then we now need more space in the PD for PTEs. But the logic
in the GMMU coding assumes if the PD has memory allocated then
that memory is sufficient. This worked back when there was no
potential for a PD to swap in page size. But now that there is
we have to re-allocate the PD doesn't have enough space for
the required PTEs.

So that's the fix - reallocate PDs when they require more
space than they currently have.

The new GMMU directory will contain the GMMU component (which used to
be a single unit). The new GMMU component is comprised of the
page_table and pd_cache units. Also when we migrate the chip specific
GMMU code out of mm_gk20a.c and mm_gp10b.c it will be placed in this
new GMMU directory.

       bytes < NVGPU_PD_CACHE_MIN)) {

This is because the nvgpu_pd_cache_alloc() function is only called,
specifically when, bytes is less than PAGE_SIZE! As such we would
only see this case when there's a bug.

So change the error condition to now check only for bytes being a
power of 2 and being greater than NVGPU_PD_CACHE_MIN. The greater
than page size check has been turned into an assert since this
should really never happen in practice unless there's a bug.

MISRA Rule 21.15 prohibits use of memcpy() with incompatible ptrs
to qualified/unqualified types.

To circumvent this issue we've introduced a new MISRA-compliant
nvgpu_memcpy() function.

This change switches non-offending memcpy usage in acr code
over to to use nvgpu_memcpy() with appropriate casts applied
to maintain consistency within nvgpu.

25ef9f869b gpu: nvgpu: fix timeout error msg in sync-unmap
Fixed the erroneous timeout message in sync-unmap and corrected the
condition for returning ETIMEDOUT.

In the original codeflow, after waiting for mapped_buffer release,
nvgpu_timeout_expired is called to check whether to return ETIMEDOUT.
However, if there is a delay between the end of the waiting and the
nvgpu_timeout_expired check, ETIMEDOUT is returned regardless if the
mapped_buffer is released with the timeout message printed. This is
an incorrect behavior. This patch fixes it by letting the refcount of
the mapped_buffer be the only source to determine the return value.

speed and minion initpll DLCMD as default.
We can no longer update the GV100 VBIOS with necessary nvlink speed

The nvlink speed should match across the endpoints. So in speed_config
