Convert disable_aspm and references to that field to use
nvgpu_is_enabled(NVGPU_SUPPORT_ASPM). Initialize it from
gk20a_platform struct at probe time.
This removes another dependency to struct gk20a_platform.

Move gk20a/platform_gk20a.h to linux specific directory as
common/linux/platform_gk20a.h since this file includes all linux specific
stuff
Fix #includes in all the files to include this file with correct path
Remove #include of this file where it is no more needed
Fix gk20a_init_sim_support() to receive struct gk20a as parameter
instead of receiving linux specific struct platform_device

This reverts commit a8643b3a99af5011f4e933967f8a09f227ce4949.
Proper resolution is implemented in user space (nvrm_gpu) to idle all channels
of TSG before unbinding a channel from it
And with that we should not see NEXT bit set on channel while unbinding
Hence revert the WAR and again return error if we find NEXT bit set on channel
Also restore the error print

In gk20a_gr_reset(), we acquire g->gr.fecs_mutex and call a bunch of APIs
But in case any of these APIs fail, we don't release the mutex and just
return the error leaking the mutex
So the next attempt to acquire g->gr.fecs_mutex results in a deadlock
Fix this by releasing the mutex before returning error

API gr_gp10b_create_sysfs() and GR HAL create_gr_sysfs() right now receive

But since this function is called from/declared in common code, we need to
remove linux dependency from it
Hence update the API and GR HAL to receive struct gk20a pointer instead
of device pointer

Nvgpu submit path has a lot of dependency on Linux framework
e.g. use of copy_from_user, use of structures defined in uapi/nvgpu headers,
dma_buf_* calls for trace support etc
Hence to keep common code independent of Linux code, move submit path to
Linux directory
Move below APIs to common/linux/channel.c
trace_write_pushbuffer()
trace_write_pushbuffer_range()
gk20a_submit_prepare_syncs()
gk20a_submit_append_priv_cmdbuf()
gk20a_submit_append_gpfifo()
gk20a_submit_channel_gpfifo()
Move below APIs to common/linux/ce2.c
gk20a_ce_execute_ops()
Define gk20a_ce_execute_ops() in common/linux/ce2.c, and declare it in
gk20a/ce2_gk20a.h since it is needed in common/mm code too
Each OS needs to implement this API separately
gk20a_channel_alloc_gpfifo() use sizeof(nvgpu_gpfifo) to get size of one gpfifo
entry, but structure nvgpu_gpfifo is linux specific
Define new nvgpu_get_gpfifo_entry_size() in linux specific code and use it
in gk20a_channel_alloc_gpfifo() to get gpfifo entry size
Each OS needs to implement this API separately
Export some APIs from gk20a/ce2_gk20a.h and gk20a/channel_gk20a.h that are

Split the ctxsw trace "core" API code into <nvgpu/ctxsw_trace.h>. This
is not perect though since there's some Linuxisms present in the HAL
and as such that code has to be hidden by the ctxsw tracing CONFIG. But
this patch should work for QNX such that it will allow the code to
build as long as CONFIG_GK20A_CTXSW_TRACE is not set.
Also fix the copywrite notice in the ctxsw code present under
common/linux to be GPL.

In current code vgpu only set error notifier for the reporting channel
but abort the whole tsg. When the tsg is aborted, all channels of the
tsg are supposed have had their error notifiers set. Set it for all
channels once any of the channels gets an MMU fault.
For now, RM server still reports num-of-channel times for tsg mmu fault.
We may optimize it in future.

Remove the buffer_attrs struct and replace it with a more
streamlined nvgpu_ctag_buffer_info struct. This struct allows
several different fields to all be passed by pointer to the
various kind/compression functions in the VM map process.
This path also moves several comptag/kind related functions
to the core vm.c code since these functions can be reused by
other OSes.

Remove the always true field 'user_mapped' from the mapped_buf
struct. All mapped_bufs are mapped by a user request since they
always originate from a dma_buf (for Linux, that is). As such
there is a fair amount of logic that could be deleted.
Linux specific: the own_mem_ref field was also be deleted. The
logic of only storing a dma_buf ref when the buffer is mapped
for the first time by a user is easy: when the mapped buffer is
found in the map cache release the outstanding dma_buf ref taken
earlier on in the map path. If the map cache does not have the
buffer simply let the higher level map code keep the dma_buf ref.
The dma_buf ref is released when the nvgpu_vm_unmap_system()
call-back is called by the unmap path.

Re-organize the unmap code to be better split between OS specific
requirements and common core requirements. The new code flow works
as follows:
nvgpu_vm_unmap()
Is the primary entrance to the unmap path. It takes a VM and a GPU
virtual address to unmap. There's also an optional batch mapping
struct.
This function is responsible for making sure there is a real buffer
and that if it's being called on a fixed mapping then the mapping
will definitely be freed (since buffers are ref-counted). Then this
function decrements the ref-count and returns.
If the ref-count hits zero then __nvgpu_vm_unmap_ref() is called
which just calls __nvgpu_vm_unmap() with the relevant batch struct
if present. This is where the real work is done. __nvgpu_vm_unmap()
clears the GMMU mapping, removes the mapped buffer from the various
lists and trees it may be in and then calls the
nvgpu_vm_unmap_system() function. This function handles any OS
specific stuff and must be defined by all VM OS implementations.
There's a a short cut used by some other core VM code to free
mappings without going through nvgpu_vm_map(). Mostly they just
directly decrement the mapping ref-count which can then call
__nvgpu_vm_unmap_ref() if the ref-count hits zero.

TSG enable sequence in native has been modified due to a
hardware bug requiring enabling all channels with NEXT and
CTX_RELOAD set in a TSG, and then enabling rest of channels.
However it is not possible to check if NEXT and CTX_RELOAD
is set in vgpu. Have a separate implementation for enabling
tsg sequence in vgpu till the fix for hardware bug is
implemented for virtualized configuration.

Issue
Currently bitmask of engine indices is being saved.
This will give wrong active engine ids for a given runlist
and s/w will end up checking/polling wrong engine_status
registers as these registers are indexed by active
engine ids. Also reset_eng_bitmask will end up
having wrong value for active engine ids to be reset.
Details for runlists serving engines ids for gv11b are:-
runlist id 0: gr = 0, grcopy 0 = 2, grcopy1 = 3
runlist id 1: async ce = 1
Incorrect values
init_runlist:705 [DBG] runlist 0 : eng bitmask 7 (eng 0, 1, 2)
init_runlist:705 [DBG] runlist 1 : eng bitmask 8 (eng 3)
Fix
Save bitmask of active engine ids in runlist info.
Right value
init_runlist:705 [DBG] runlist 0 : eng bitmask d (eng 0, 2, 3)
init_runlist:705 [DBG] runlist 1 : eng bitmask 2 (eng 1)

gk20a/clk_gk20a.h is a common file but still includes linux specific headers
Clean them up as below
- put linux/clk-provider.h include under config CONFIG_COMMON_CLK
- move linux/clkdev.h include to common/linux/platform_gk20a_tegra.c as it is no
longer needed in this file

Migrate ctxsw_trace_gk20a.c to common/linux/ctxsw_trace.c. This
has been done becasue the ctxsw tracing code is currently too
tightly tied to the Linux OS due to usage of a couple system calls:
- poll()
- mmap()
And general Linux driver framework code. As a result pulling the
logic out of the FECS tracing code is simply too large a scope for
time time being.
Instead the code was just copied as much as possible. The HAL ops
for the FECS code was hidden behind the FECS tracing config so
that the vm_area_struct is not used when QNX does not define said
config. All other non-HAL functions called by the FECS ctxsw
tracing code ha now also been hidden by this config. This is not
pretty but for the time being it seems like the way to go.

In gk20a_fifo_tsg_unbind_channel(), we always verify channel status before
unbinding a channel from TSG
But in case TSG has alread timed out we never re-enable it so it does not
make sense to inspect channel status anyways
So skip channel status verification in case TSG has timed out

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.

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

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.
