Add new variable in nvgpu_as_map_buffer_ex_args for app
to specify the platform atomic support for the page.
When platform atomic attribute flag is set, pte memory
aperture is set to be coherent type.

renamed nvgpu_aperture_mask_coh -> nvgpu_aperture_mask_raw
function.

45fa0441f7 gpu: nvgpu: allocate only active runlists
Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Skip allocation and initialization of inactive runlists.
Active runlists info is stored in the active_runlist_info array.
If a runlist is active, then runlist_info[runlist_id] points to
one entry in active_runlist_info. Otherwise, runlist_info[runlist_id]
is NULL.

Operations that used to walk through all runlists are modified to
walk though active runlists only.

5fdda1b075 gpu: nvgpu: array of pointers to runlists
Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Use an array of pointers to runlists in fifo_gk20a. The array
keeps existing indexing by runlist_id. In this patch a context
is still allocated for each possible runlist, but follow up
patch will allow to skip context allocation for inactive
runlists.

8db1955d74 gpu: nvgpu: split semaphore.c file into multiple units
The file semaphore.c is now split into 4 units namely
semaphore, semaphore_hw, semaphore_pool and semaphore_sea.

Each of the above units now have separate compilation units under
common/semaphore/. The public APIs corresponding to each unit is
present in include/nvgpu/semaphore.h. The dependency graph of the
below units is as follows where '->' indicates left depends on right.

semaphore -> semaphore_hw -> semaphore_pool -> semaphore_sea

Some of the other major changes made in this patch are as follows
  i) Renamed some of the functions.
  ii) Some functions are changed from private to public.
  iii) Public header for semaphore contains only the declaration of the
       corresponding structs as an opaque structure.
  iv) Constructed a private header to contain internal functions common
      to all the units and struct definitions corresponding to each unit.
  v)  Added new functions to provide access to internal members of the
      units.

Add vmid field to this struct since it is required for QNX

Remove use of hashtables and simply use linked list to simplify

so perf hit could be ignored

Rename hash_lock mutex to list_lock

struct gk20a_fecs_trace and mutex list_lock are still declared in
gk20a/fecs_trace_gk20a.c, hence they cannot be used in new unit yet

Rename and update all gk20a_fecs_trace_hash_*() APIs to appropriate

gk20a_fecs_trace_ring_read() returns number of trace entries written
to local buffer if successful, otherwise returns error

In case there is really an invalid entry, gk20a_fecs_trace_poll()
will just stop reading more entries, write current read pointer to
h/w and return

When gk20a_fecs_trace_poll() is called next time, we again read that
invalid entry, and again skip it, and again return
This keeps happening, and we never move on to read new entries

Fix this by always continuing to read next entry irrespective
of current entry is valid or not
gk20a_fecs_trace_poll() now just prints a debug message instead of
breaking the loop

nvgpu driver uses the h/w headers for reading pbdma_status registers
directly in the common code path. Replace the use of the H/W headers by
using the APIs of the pbdma_status unit. Use the HAL ops functions
read_pbdma_status_info() to do a read of the pbdma status register.

061aa66adc gpu: nvgpu: move engine specific functions to common/fifo
The following changes are done in this patch.

1) gk20a_fifo_get_engine_info() is moved to common/fifo/engine.c
and is renamed to gk20a_fifo_get_active_engine_info() to reflect
accurately the purpose of the function.

2) move the definition of enum fifo_engine to <nvgpu/engines.h> and
add the prefix NVGPU_

3) move the following functions related to engines in fifo_gk20a.c to
common/fifo/engines.c and replace their signature by adding the prefix
nvgpu_engine and removing gk20a_fifo.

gk20a_fifo_get_active_engine_info
gk20a_fifo_engine_enum_from_type
gk20a_fifo_get_engine_ids

Drop the "runlist_" part in the runlist section of the HAL ops. For
example:

- old: g->ops.runlist.runlist_wait_pending
- new: g->ops.runlist.wait_pending

At the same time, drop the "fifo_" part from the function names. For
example:

- old: gk20a_fifo_runlist_wait_pending
- new: gk20a_runlist_wait_pending

Also rename eng_runlist_base_size to count_max. The size of the
eng_runlist_base register array depicts the maximum possible number of
runlists in the chip for which count_max is more descriptive.

A comment for gk20a_fifo_update_runlist() says:

 /* add/remove a channel from runlist
    special cases below: runlist->active_channels will NOT be changed.
    (ch == NULL && !add) means remove all active channels from runlist.
    (ch == NULL &&  add) means restore all active channels on runlist. */

Those special cases call for a new function, so add that. Delete the
update_runlist HAL op and add update_for_channel (like update_runlist
without the special cases) and reload (no channel to add or remove, just
the special cases).

While at it, rename gk20a_fifo_update_runlist_ids to
nvgpu_runlist_reload_ids. It's common across chips and does what the
reload HAL does but for a list of several IDs.

254253732c gpu: nvgpu: add new unit for GR subcontext
Add new unit common/gr/subctx.c to manage GR subcontext
This unit provides interfaces to allocate/free/load GR subcontext

Add new header file include/nvgpu/gr/subctx.h to declare all the
interfaces.

Right now channel_gk20a structure directly includes a nvgpu_mem
for context header.
Declare a new structure nvgpu_gr_subctx for subcontext and include
this from channel_gk20a

Make all necessary changes to refer ctx_header from subctx instead
of directly referencing it from channel

13afcc24c3 gpu: nvgpu: non abortable TSG for vidmem-clear
When an engine faults due to unbound instance block, all
active TSGs are currently aborted. This includes the TSG
used by vidmem-clear task to clear vidmem buffers. From
this point nvgpu_vidmem_clear cannot submit jobs anymore.

Define TSG in MM CE context as non-abortable, and skip it
when aborting active TSGs.
