We currently check that no job is pending before proceeding with
suspend. This prevents suspend, when we could simply disable and
preempt all channels. Moreover, pending jobs accounting is done
using pm_runtime usage count, which is not updated for GPUs with
pm_runtime disabled (e.g. vgpu).
Replaced the check on pm_runtime usage count, with a check on
gk20a handle usage count. Suspend is allowed when there is no
task inside a busy/idle sequence.

We currently check that engine is idle before proceeding with
suspend. This prevents suspend when we could simply disable and
preempt all channels. Moreover, doing such a check in virtualization
case, would require to query engine status from RM server, before
proceeding with suspend.
Removed check on engine idle for system suspend.

Delte the Linux headers and make some modifications to get rid of the
minor compilation issues that resulted.
- Add <linux/iommu.h> to os_linux.h
- Delete #if 0 code that "flushed" a buffer in gr_gk20a.c
- Delete FLUSH_CPU_DCACHE() macro
- Move the cache flush definitions to <nvgpu/linux/vm.h>
and include this header in sim_gk20a.c. This file will
not be used by QNX so this should be fine.
- Add <linux/pci_ids.h> to gp106/bios_gp106.c and
gp106/mclk_gp106.c.
- Move function to common/linux/dmabuf.h since it is a
dmabuf related function and uses a struct device pointer
as an argument.

In gk20a_fifo_tsg_unbind_channel(), we disable/preempt TSG, unbind one channel
from TSG, and then re-enable rest of the channels in TSG
But it is possible that TSG has already timed out due to some error and is
already disabled
If we re-enable all channels in such case, it can cause random issues right
after re-enabling faulted channel
Hence do not re-enable TSG if it has timedout
Since we disable all channels of TSG if one channel encounters fatal error,
it is safe to assume that TSG has timed out if one channel has timed out

Add max_css_buffer_size to gpu characteristics. In the virtual
case, the size of the cycle stats snapshot buffer is constrained
by the size of the mempool shared between the guest OS and the
RM server, so tools need to find out what is the maximum size
allowed.
In the native case, we return 0xffffffff to indicate
that the buffer size is unbounded (subject to memory availability),
in the virtual case we return the size of the mempool.
Also collapse native init_cyclestats functions to a single version,
as each chip had identical versions of the code.

PMU response(intr callback for messages) can run faster
than the kthread posting commands to PMU.
This causes the PMU message callback to skip important pmu
state change(which happens just after the PMU command is posted).
Solution:
State change should be triggered from only inside the intr callback.
Other places can only update the pmu_state variable.
This change also adds error check to print in case command post fails.

Move vm_priv.h to <nvgpu/linux/vm.h> and rename nvgpu_vm_map()
to nvgpu_vm_map_linux(). Also remove a redundant unmap function
from the unmap path. These changes are the beginning of reworking
the nvgpu Linux mapping and unmapping code.
The rest of this patch is just the necessary changes to use the
new map function naming and the new path to the Linux vm header.
Patch Series Goal
-----------------
There's two major goals for this patch series. Note that these
goals are not achieved in this patch. There will be subsequent
patches.
1. Remove all last vestiges of Linux code from common/mm/vm.c
2. Implement map caching in the common/mm/vm.c code
To accomplish this firstly the VM mapping code needs to have the
struct nvgpu_mapped_buf data struct be completely Linux free. That
means implementing an abstraction for this to hold the Linux stuff
that mapped buffers carry about (SGT, dma_buf). This is why the
vm_priv.h code has been moved: it will need to be included by the
<nvgpu/vm.h> header so that the OS specific struct can be pulled
into struct nvgpu_mapped_buf.
Next renaming the nvgpu_vm_map() to nvgpu_vm_map_linux() is in
preparation for adding a new nvgpu_vm_map() that handles the
map caching with nvgpu_mapped_buf. The mapping code is fairly
straight forward: nvgpu_vm_map does OS generic stuff; each OS
then calls this function from an nvgpu_vm_map_<OS>() or the like
that does any OS specific adjustments/management.
Freeing buffers is much more tricky however. The maps are all
reference counted since userspace does not track buffers and
expects us to handle this instead. Ugh! Since there's ref-counts
the free code will require a callback into the OS specific code
since the OS specific code cannot free a buffer directly. THis
make's the path for freeing a buffer quite convoluted.

Move much of the remaining generic MM code to a new common location:
common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This
mostly consists of init and cleanup code to handle the common MM
data structures like the VIDMEM code, address spaces for various
engines, etc.
A few more indepth changes were made as well.
1. alloc_inst_block() has been added to the MM HAL. This used to be
defined directly in the gk20a code but it used a register. As a
result, if this register hypothetically changes in the future,
it would need to become a HAL anyway. This path preempts that
and for now just defines all HALs to use the gk20a version.
2. Rename as much as possible: global functions are, for the most
part, prepended with nvgpu (there are a few exceptions which I
have yet to decide what to do with). Functions that are static
are renamed to be as consistent with their functionality as
possible since in some cases function effect and function name
have diverged.

Patch buffer can hold 128 u32 entries. Each patch write
takes total of 2 u32 entries, 1 u32 for addr and 1 u32
for data. Ideally 64 entries could be written before buffer
overflows. Driver patch some things when creating the channel,
and later when context switch type is changed after channel is loaded.
Reset patch_ctx.data_count before beginning patch
write otherwise system might not be in a state to accept all
patch writes even if patch buffer has valid entries.
If the patch buffer has non-zero entries, then the patch buffer
would be read and all pri writes would be sent out. Once done,
ucode updates the main header patch buffer count to 0.
Without this fix, below priv errors seen on t186 platforms

Convert the work_struct used by the vidmem background clearing to
a thread to make it more cross platform. The thread waits on a
condition variable to determine when work needs to be done. The
signal comes from the DMA API when it enqueues a new nvgpu_mem that
needs clearing.
Add logic for handling suspend: the CE cannot be accessed while
the GPU is suspended. As such the background thread must be paused
while the GPU is suspended and the CE is not available.
Several other changes were also made:
o Move the code that enqueues a nvgpu_mem from the DMA API
code to a function in the VIDMEM code.
o Move nvgpu_vidmem_get_pending_alloc() to the Linux specific
code as this function is only used there. It's a trivial
function that QNX can easily implement as well.
o Remove the was_empty logic from the enqueue. Now just always
signal the condition variable when anew nvgpu_mem comes in.
o Move CE suspend to after MM suspend.

Refactor the last nvgpu_vm functions from the mm_gk20a.c code. This
removes some usages of dma_buf from the mm_gk20a.c code, too, which
helps make mm_gk20a.c less Linux specific.
Also delete some header files that are no longer necessary in
gk20a/mm_gk20a.c which are Linux specific. The mm_gk20a.c code is now
quite close to being Linux free.

Move most of the dma_buf usage present in the mm_gk20a.c code
out to Linux specific code and some commom/mm code. There's
two primary groups of code:
1. dma_buf priv field code (for holding comptag data)
2. Comptag usage that relies on dma_buf pointers
For (1) the dma_buf code was simply moved to common/linux/dmabuf.c
since most of this code is clearly Linux specific.
The comptag code was a bit more complicated since there is two
parts to the comptag code. Firstly there's the code that manages
the comptag memory. This is essentially a simple allocator. This
was moved to common/mm/comptags.c since it can be shared across
all chips. The second set of code is moved to
common/linux/comptags.c since it is the interface between dma_bufs
and the comptag memory.
Two other fixes were done as well:
- Add struct gk20a to the comptag allocator init so that
the proper nvgpu_vzalloc() function could be used.
- Add necessary includes to common/linux/vm_priv.h.

This change contains a generic cleanup of linux dependent parts of the
dbg_gpu_gk20a.* files. The following changes have been made
1) Moving methods into ioctl_dbg.* inside common/linux/
2) The structures dbg_session_gk20a and dbg_session_channel_data have
been split into two parts. struct device *dev is removed from
struct dbg_session_gk20a and instead packed into struct
dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into
ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and
remains in dbg_gpu_gk20a. Similarly, struct file is removed from
struct dbg_session_channel_data and is now packed into struct
dbg_session_channel_data_linux alongwith dbg_session_channel_data and
is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of
linux dependencies and remains in dbg_gpu_gk20a.
3) A callback function is added in order to release the
dbg_session_channel_data.
