Begin removing all of the myriad flag variables in struct gk20a and
replace that with one API that checks for flags being enabled or
disabled. The API is as follows:
bool nvgpu_is_enabled(struct gk20a *g, int flag);
bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state);
These APIs allow many of the gk20a flags to be replaced by defines.
This makes flag usage consistent and saves a small amount of memory in
struct gk20a. Also it makes struct gk20a easier to read since there's
less clutter scattered through out.

pending_sema_waits and a few other variables in struct gk20a is used
in gk20a shutdown path but we didn't initialize them in vgpu. I added
a function vgpu_init_vars dedicated to init variables for struct gk20a.
The native code also similar function nvgpu_init_vars().
This is a quick fix. Finally, the common probe code is better be put
in common function btween vgpu and native gpu.

This change refactors the teardown in remove to ensure that it is
possible to unload the driver while leaving fds open. This is achieved
by making sure that the SW state is kept alive till all fds are closed
and by checking that subsequent calls to ioctls after the teardown fail.
Normally, this would be achieved ny calls into gk20a_busy(), but in
kickoff we dont call into that to reduce latency, so we need to check
the driver status directly, and also in some of the functions
as we need to make sure the ioctl does not dereference the device or
platform struct

Implement a worker thread to replace the delayed works in channel
watchdog and job cleanups. Watchdog runs by polling the channel states
periodically, and job cleanup is performed on channels that are appended
on a work queue consumed by the worker thread. Handling both of these
two in the same thread makes it impossible for them to cause a deadlock,
as has previously happened.
The watchdog takes references to channels during checking and possibly
recovering channels. Jobs in the cleanup queue have an additional
reference taken which is released after the channel is processed. The
worker is woken up from periodic sleep when channels are added to the
queue.
Currently, the queue is only used for job cleanups, but it is extendable
for other per-channel works too. The worker can also process other
periodic actions dependent on channels.
Neither the semantics of timeout handling or of job cleanups are yet
significantly changed - this patch only serializes them into one
background thread.
Each job that needs cleanup is tracked and holds a reference to its
channel and a power reference, and timeouts can only be processed on
channels that are tracked, so the thread will always be idle if the
system is going to be suspended, so there is currently no need to
explicitly suspend or stop it.

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
Export gk20a_railgating_debugfs_init() so that we can call
it from gk20a_debug_init()

We currenlty initialize both runtime PM and pm_domains frameworks
and use pm_domain to control runtime power management of NvGPU
But since GPU has a separate rail, using pm_domain is not
strictly required
Hence remove pm_domain support and use runtime PM only for all
the power management
This also simplifies the code a lot
Initialization in gk20a_pm_init()
- if railgate_delay is set, set autosuspend delay of runtime PM
- try enabling runtime PM
- if runtime PM is now enabled, keep GPU railgated
- if runtime PM is not enabled, keep GPU unrailgated
- if can_railgate = false, disable runtime PM and keep
GPU unrailgated
Set gk20a_pm_ops with below callbacks for runtime PM
static const struct dev_pm_ops gk20a_pm_ops = {
.runtime_resume = gk20a_pm_runtime_resume,
.runtime_suspend = gk20a_pm_runtime_suspend,
.resume = gk20a_pm_resume,
.suspend = gk20a_pm_suspend,
}
Move gk20a_busy() to use runtime checks of pm_runtime_enabled()
instead of using compile time checks on CONFIG_PM
Clean up some pm_domain related code
Remove use of gk20a_pm_enable/disable_clk() since this
should be already done in platform specific unrailgate()/
railgate() APIs
Fix "railgate_delay" and "railgate_enable" sysfs to use
runtime PM calls
For VGPU, disable runtime PM during vgpu_pm_init()
With this, we will initialize vgpu with vgpu_pm_finalize_poweron()
upon first call to gk20a_busy()

the devnodes to their own directory so that reading this one
directory can be allowed.
At the same time rename the nodes to start with string "card-".
