Earlier implementation of railgate disable config is disabling
runtime pm during pm_init. This is causing multiple issues:
1. gpu rail will be on as soon as nvgpu driver probe is called.
Actual gpu hw init may happen at much later point of time.
2. This is breaking railgate_enable sysfs node functionality.
railgate_enable is not working if runtime pm is disabled.
To avoid all these issues for railgate disable, enable runtime pm
during pm_init and set auto-suspend delay to negative (-1), which
will disable runtime pm suspend calls.
Also fixed following issues along with this:
1. Updated railgate_enable debugfs implementation to use auto-suspend delay.
To disable railgating:
Set auto-suspend delay with negative value(-1) which will disable runtime
pm suspend.
To enable railgating:
Set auto-suspend delay with railgate_delay value.
Also removed redundant user_railgate_disabled gk20a device data and
replaced with can_railgate, where ever it is applicable.
2. Initialized default railgate_delay to 500msec to avoid railgate
on/off transitions with railigate enable from disabled state.
3. Created railgate_residency debug fs node irrespective of can_railgate
initial state. This is helping with the case, where initial state of
railgate state off and then railgate enable is done through sysfs node.

Switch all logging to nvgpu_log*(). gk20a_dbg* macros are
intentionally left there because of use from other repositories.
Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages
are deleted.

This patch deals with cleanups meant to make things simpler for the
upcoming os abstraction patches for the sync framework. This patch
causes some substantial changes which are listed out as follows.
1) sync_timeline is moved out of gk20a_fence into struct
nvgpu_channel_linux. New function pointers are created to facilitate os
independent methods for enabling/disabling timeline and are now named
as os_fence_framework. These function pointers are located in the struct
os_channel under struct gk20a.
2) construction of the channel_sync require nvgpu_finalize_poweron_linux()
to be invoked before invocations to nvgpu_init_mm_ce_context(). Hence,
these methods are now moved away from gk20a_finalize_poweron() and
invoked after nvgpu_finalize_poweron_linux().
3) sync_fence creation is now delinked from fence construction and move
to the channel_sync_gk20a's channel_incr methods. These sync_fences are
mainly associated with post_fences.
4) In case userspace requires the sync_fences to be constructed, we
try to obtain an fd before the gk20a_channel_submit_gpfifo() instead of
trying to do that later. This is used to avoid potential after effects
of duplicate work submission due to failure to obtain an unused fd.

This CL handles
- erroneous use of boot_0 function pointer
before being assigned in __nvgpu_check_gpu_state
- And proper handling of error returned from gk20a_readl
in gk20a_mc_boot_0
With these fixes crash is not seen in case mc_boot_0 read
returns 0 in gk20a_mc_boot_0
- And also this handles the recursion caused by mc.boot_0()
calling nvgpu_readl and nvgpu_readl in turn
calling mc.boot_0 in case of read failure

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.

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.

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.

We currently check that engine is idle before proceeding with

preempt all channels. Moreover, doing such a check in virtualization
case, would require to query engine status from RM server, before

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.

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.

Allow userspace to control directly the PTE kind for the mappings by
supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX.
In particular, in this mode, the userspace will tell the kernel
whether the kind is compressible, and if so, what is the
incompressible fallback kind. By supplying only the compressible kind,
the userspace can require that the map kind will not be demoted to the
incompressible fallback kind in case of comptag allocation failure.
Add also a GPU characteristics flag
NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct
kind control is supported.
Fix indentation of nvgpu_as_map_buffer_ex_args header comment.
