Update pmu ucode version for next pmu to 29323513.
This version is taken from P4 CL#29323216.
Changes:
- Enabled ACR task support
- Disabled few features/code for commands to work
- ELPG fifo preemption hals fixed
- Halt functions in ELPG save and restore functions
are commented as bloaded flag is not getting set. This
is not significant as this change will not have any impact
in elpg functionality.

By always mapping gmmu kernel page using 4kB page, it'll be consistent
with native nvgpu driver. It's a workaround for enabling 64KB os kernel
page support.
In long term solution, GMMU_PAGE_SIZE_KERNEL will be os kernel page
size, and function nvgpu_gmmu_update_page_table will choose big page or
small page by comparing the size of GMMU_PAGE_SIZE_KERNEL with the size
of small or big pages. Regardingly vgpu will choose kernel page size by
comparing the size too when send map commands to server.

Update gk20a_ctrl_dev_ioctl() to fetch gpu_instance_id with
nvgpu_get_gpu_instance_id_from_cdev() and gr_instance_id with
nvgpu_grmgr_get_gr_instance_id().
Get instance specific GR engine configuration pointer with
nvgpu_gr_get_gpu_instance_config_ptr()
Update gk20a_ctrl_ioctl_gpu_characteristics() to return instance
specific characteristics with below changes :
- 0th GPU instance is a physical instance. Set a limited and relevant
characteristics flags for 0th instance.
For rest of the instances and non-MIG mode, continue fetching flags
with nvgpu_ctrl_ioctl_gpu_characteristics_flags.
- nvgpu_set_preemption_mode_flags() should be set only for non-MIG mode
and non-zero instance in MIG mode.
- In MIG mode, 0th instance does not support any classes. Rest of the
instances support only compute, copy and gpfifo classes.
Non-MIG mode supports all the classes including graphics ones.
- Fetch gpu_instance_id/gr_sys_pipe_id/gr_instance_id from gpu_instance
pointer.
- Fetch max_veid_count_per_tsg from gpu_instance pointer.
Also update nvgpu_gr_get_zcull_ptr() and nvgpu_gr_get_zbc_ptr() to
return instance specific pointers. zcull/zbc are not supported in MIG
mode, this is just for consistency of the code.

Any PDE can allocate memory with a specific page size. That means memory
allocation with page size 4K and 64K will be realized by different PDEs
with page size (or PTE size) 4K and 64K respectively. To accomplish this
user vma is required to be pde aligned.
Currently, user vma is aligned by (big_page_size << 10) carried over
from when pde size was equivalent to (big_page_size << 10).
Modify user vma alignment check to use pde size.

This also requires to move unmap sequence to OS specific function since
different unmap API is now needed for linux and QNX.
Also call nvgpu_prof_free_pma_stream_priv_data() before

Also, logical to physical mapping is not present for a floorswept gpc so

The simulator ring buffer DMA interface supports buffers of the following sizes:
4, 8, 12 and 16K. At present, it is configured to 4K and it happens to match
with the kernel PAGE_SIZE, which is used to wrap back the GET/PUT pointers once
4K is reached. However, this is not always true; for instance, take 64K pages.
Hence, replace PAGE_SIZE with SIM_BFR_SIZE.
Introduce macro NVGPU_CPU_PAGE_SIZE which aliases to PAGE_SIZE and replace
latter with former.

Mapping of large buffers to GMMU end up needing many
pages for the PTE tables. Allocating these one by one
can end up being a performance bottleneck, particularly
in the virtualized case.
This is adding the following changes:
- As the TLB invalidation doesn't have access to mem_off,
allow top-level allocation by alloc_cache_direct().
- Define NVGPU_PD_CACHE_SIZE, the allocation size for a new slab
for the PD cache, effectively set to 64K bytes
- Use the PD cache for any allocation < NVGPU_PD_CACHE_SIZE
When freeing up cached entries, avoid prefetch errors by
invalidating the entry (memset to 0).
- Try to fall back to direct allocation of smaller chunk for
contiguous allocation failures.
- Unit test changes.

Right now PMA byte buffer address is allocated in the range of
0x1ffc010000. The register that stores this address is only 32-bit and
there is no corresponding _hi() register, so the address must fit in
32 bits.
Update nvgpu_vm_init() parameters in nvgpu_perfbuf_init_vm() so that a
low_hole of only 4K is used. This allows the address to be allocated
in the range of 0x4000000.
Also map byte buffer before PMA stream buffer so that byte buffer always
gets lower address.
There is only one PMA stream buffer allowed to be mapped right now so
this works for now. But in future multiple buffers can be mapped and this
solution needs to be reworked.

passed while allocating context, get default preemption modes with

Rework nvgpu_gr_ctx_check_valid_preemption_mode() so that it is more
