When trying to power down GPU the engine might be still busy. In this
case delay power down by returning -EBUSY from
gk20a_pm_runtime_suspend().

Instead of blocking for gpfifo space in the nvgpu driver,
return -EAGAIN and allow userspace to decide the blocking

When allocating discontiguous memory composed of several chunks,
update also the number of pages used by the current chunk, if a large
chunk was not available and a retry is performed with a smaller one.
Failing to do this would result in too few chunks reserved for a large
enough allocation in certain conditions.

An empty list of soon-to-be-freed userspace vidmem buffers is not enough
to safely assume that an allocation may succeed or not if tried again,
because removal from the list and actually marking the memory freed is
not atomic. Fix this by using an atomic counter for the number of
pending frees (so that it's still safe to first remove from the job list
and then perform the free), and making allocation attempts combined with
a test of pending frees atomic.
This still does not guarantee that there is memory available (as the
actual amount of pending memory in bytes plus the current free amount
isn't computed), but removes the race that produces false negatives in
case a single program expects repeated frees and allocs to succeed.

pmu_api.h - all the current APIs used in igpu
pmu_common.h - common defines for all APIs
pmu_gk20a.h - SW defines specific needed for nvgpu
like PMU version, PMU SW structure definition etc.
Splitting APIs to separate files allows us to use auto
generated PMU task headers from RM
We have script which generates pmu interface herader files
in linux format. It replaces RM with NV. Adding typedef in existing pmu
code make auto generated files easy to compile/add

We have completely different versions of probe for
nvgpu and pci device
Extract out common steps into nvgpu_probe() function
and separate it out in new file nvgpu_common.c
Divide task of nvgpu_probe() into further smaller
functions
Do platform specific things (like irq handling,
memresource management, power management) only in
individual probes and then call nvgpu_probe() to
complete the common initialization
Move all debugfs initialization to common gk20a_debug_init()
This also helps to bringup all debug nodes to pci device
Pass debugfs_symlink name as a parameter to gk20a_debug_init()
This allows us to set separate debugfs symlink for nvgpu
and pci device
In case of railgating, cde and ce debugfs, check if
platform supports them or not
Copy vidmem_is_vidmem from platform to mm structure
and set it to true for pci device
Return from gk20a_scale_init() if we don't have either of
governor or qos_notifier
Fix gk20a_alloc_debugfs_init() and gk20a_secure_page_alloc()
to receive device pointer instead of platform_device

it from gk20a_debug_init()

In pramin_access_batched(), in each iteration of the
loop we first decide size of data that we should write
in that iteration.
In case this size is equal to length of the chunk, we
need to move to use next chunk for subsequent iteration
But since we change offset variable before we check
above, we end up using same chunk in next iteration
Fix this by correcting the sequnce to first check if
we should move to next chunk and then only adjust
the offset variable

Allocting blob space for pmu might need fixed address
allocation in vidmem and during boot up
But if some page tables are allocated before blob space,
blob space allocation could fail
Fix this by allocating blob space early during boot up

Store allocator pointer for each mem_desc
This pointer should be used while freeing the mem
instead of assuming a common allocator
Add flag user_mem to mem_desc which will be set
only in case of User vidmem allocations
We will delay free of mem in worker only if this
flag is set on mem. Otherwise, we will free it
immediately
This is needed so that all kernel allocations
can work with both sysmem and vidmem

We clear buffers allocated in vidmem in buffer free path.
But to clear buffers, we need to submit CE jobs and this
could cause issues/races if free called from critical
path
Hence solve this by moving buffer clear/free to a worker
gk20a_gmmu_free_attr_vid() will now just put mem_desc into
a list and schedule a worker
And worker thread will traverse the list and clear/free
the allocations
In struct gk20a_vidmem_buf, mem variable is statically
allocated. But since we delay free of mem, convert this
variable into a pointer and allocate it dynamically
Since we delay free of vidmem memory, it is now possible
to face OOM conditions during allocations. Hence while
allocating block until we have sufficient memory
available with an upper limit of 1S

We currently clear vidmem pages in gk20a_gmmu_alloc_attr_vid_at()
i.e. allocation path for each buffer
But since buffer allocation path could be latency critical,
clear whole vidmem first and before first User allcation
in gk20a_vidmem_buf_alloc()
And then clear buffer pages while releasing the buffer
In this way, we can ensure that vidmem pages are already cleared
during buffer allocation path
At a later stage, clearing of pages can be removed from free path
and moved to a separate worker as well
At this point, first allocation has overhead of clearing whole
vidmem which takes about 380mS and this should improve once
clocks are raised.
Also, this is one time larency, and subsequent allocations
should not have any overhead for clearing at all
Add API gk20a_vidmem_clear_all() to clear whole vidmem
We have WPR buffers allocated during boot up and
at fixed address in vidmem.
To prevent overwriting to these buffers in gk20a_vidmem_clear_all(),
clear whole vidmem except for the bootstrap allocator carveout
Add new API gk20a_gmmu_clear_vidmem_mem() to clear one mem_desc

Event notifications on TSGs should only be sent to the channel that caused the
event to happen in the first place, not evey channel in the tsg. Any more and
the debugger will not be able to tell what channel actually got the event.
Worse yet, if all the channels in a tsg are bound to the same debug session
(as is the case with cuda-gdb), then multiple nvgpu events for the same gpu
event will be triggered, causing events to be buffered and the client to get
out of sync.
One gpu exception, one nvgpu event per tsg.

Implement an allocator suitable for managing the video memory on dGPUs.
It works by allocating chunks from an underlying buddy allocator and
collating the chunks together (similar to what an sgt does in the
wider Linux kernel). This handles the ability to get large buffers in
potentially fragmented memory. The GMMU can then obviously map the
physical vidmem into contiguous GVA spaces.
