d538737ba1 gpu: nvgpu: Add ELPG_MS protected call for L2 flush
- if L2 flush is done when ELPG_MS feature is engaged
  then it can cause some of the signals to go non-idle.
  This can cause idle snap in ELPG_MS.
- To avoid the idle snap, add elpg_ms protected call before
  L2 flush operation

1b1d183b9c gpu: nvgpu: simplify gmmu map calls
Introduce nvgpu_gmmu_map_partial() to map a specific size of a buffer
represented by nvgpu_mem, or what nvgpu_gmmu_map() used to do. Delete
the size parameter from nvgpu_gmmu_map() such that it now maps the
entire buffer. The separate size parameter is a historical artifact from
when nvgpu_mem did not exist yet; the typical use is to map the entire
buffer.

Mapping at a certain address with nvgpu_gmmu_map_fixed() still takes the
size parameter.

The returned address still has to be stored somewhere, typically to
mem.gpu_va by the caller so that the matching unmap variant finds the
right address.

44422db851 gpu: nvgpu: simplify gmmu unmap calls
Introduce nvgpu_gmmu_unmap_addr() to unmap a nvgpu_mem that was mapped
at some other address than mem.gpu_va, which can be the case for buffers
that are shared across different address spaces. Delete the address
parameter from nvgpu_gmmu_unmap(), as the common case is to store the
address to mem.gpu_va when mapping the buffer.

Modify some instances of consecutive unmap + free calls to call just
nvgpu_dma_unmap_free().

3a764030b1 gpu: nvgpu: Add new mm HAL and move cache code to that HAL
Add a new MM HAL directory to contain all MM related HAL units.
As part of this change add cache unit to the MM HAL. This contains
several related fixes:

1. Move the cache code in gk20a/mm_gk20a.c and gv11b/mm_gv11b.c to
   the new cache HAL. Update makefiles and header includes to take
   this into account. Also rename gk20a_{read,write}l() to their
   nvgpu_ variants.

2. Update the MM gops: move the cache related functions to the new
   cache HAL and update all calls to this HAL to reflect the new
   name.

3. Update some direct calls to gk20a MM cache ops to pass through
   the HAL instead.

4. Update the unit tests for various MM related things to use the
   new MM HAL locations.

This change accomplishes two architecture design goals. Firstly it
removes a multiple HW include from mm_gk20a.c (the flush HW header).
Secondly it moves code from the gk20a/ and gv11b/ directories into
more proper locations under hal/.
