The gp10b gr status dump can get printed so early that this array is
null, so don't access it in that case.

Move clock APIs from gk20a_platform to gpu_ops. At the same time
allow use of internal get_rate/set_rate for querying both GPCCLK
and PWRCLK on iGPU.
At the same time we can replace calls to clk framework with the
new HAL and drop direct dependency to clk framework.
gp10b ops were replaced as a whole at HAL initialization. That
replaces anything set in platform probe stage, so reduce that to
touch only clock gating regs.

Read fuse values from GPU's own fuse registers instead of Tegra fuse
registers whenever possible. This reduces the number of dependencies
to Linux fuse code.
Some fuses do not have a corresponding register in GPU, so they're
left as is.

Instead of using Linux APIs for mutex and spinlocks
directly, use new APIs defined in <nvgpu/lock.h>
Replace Linux specific mutex/spinlock declaration,
init, lock, unlock APIs with new APIs
e.g
struct mutex is replaced by struct nvgpu_mutex and
mutex_lock() is replaced by nvgpu_mutex_acquire()
And also include <nvgpu/lock.h> instead of including
<linux/mutex.h> and <linux/spinlock.h>
Add explicit nvgpu/lock.h includes to below
files to fix complilation failures.

This ioctl can be used on gp10b to set a flag in the context header
indicating this context should be run at elevated clock
frequency. FECS ctxsw ucode will read this flag as part of the context
switch and will request higher GPU clock frequencies from BPMP for the
duration of the context execution.

Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore
code is common to all chips.
Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu
and rename it to semaphore.h. Also update all places where the header
is inluced to use the new path.
This revealed an odd location for the enum gk20a_mem_rw_flag. This should
be in the mm headers. As a result many places that did not need anything
semaphore related had to include the semaphore header file. Fixing this
oddity allowed the semaphore include to be removed from many C files that
did not need it.

This also changes the behavior of several functions to wait for
the full timeout for each operation that can timeout. Previously
the timeout was shared across each operation.

We can trigger CILP only if SM debug mode is on.
So in fecs interrupt handler, we could have graphics context
running for which SM debug mode is disabled.
And in that case we skip posting of cilp completion
events to UMD.
But since CILP event was anyways triggered, we need to post
events to UMD irrespective of SM debug mode is enabled
at that point or not
Hence remove check gk20a_gr_sm_debugger_attached() for
posting events to UMD

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.

For devices that have vidmem available, use the vidmem allocator in
gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem.
Because all of the buffers haven't been tested to work in vidmem yet,
rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at
the end to declare explicitly that vidmem is used. Enabling vidmem for
each now is a matter of removing "_sys" from the function call.

* Moving jiffy counter after preemption work to more accurately and fairly give
time for preemption to complete.
* Add debug information to coordinate waiting.
* Check if cilp is still pending before returning the timedout error.

To support vidmem, pass g and mem_desc to the buffer memory accessor
functions. This allows the functions to select the memory access method
based on the buffer aperture instead of using the cpu pointer directly
(like until now). The selection and aperture support will be in another
patch; this patch only refactors these accessors, but keeps the
underlying functionality as-is.

Separate out new API gr_gp10b_set_ctxsw_preemption_mode()
which will check requested preemption modes and take appropriate
action for each preemption mode
This API will also do some sanity checking for valid
preemption modes and combinations
Define API set_preemption_mode() for gp10b which will set the
preemption modes passed as argument and then use
gr_gp10b_set_ctxsw_preemption_mode() and
update_ctxsw_preemption_mode() to update preemption mode
Legacy path from gr_gp10b_alloc_gr_ctx() will convert
flags NVGPU_ALLOC_OBJ_FLAGS_* into appropriate preemption modes
and then call gr_gp10b_set_ctxsw_preemption_mode()
New API set_preemption_mode() will use new flags
NVGPU_GRAPHICS/COMPUTE_PREEMPTION_MODE_* and set and update
ctxsw preemption mode
In gr_gp10b_update_ctxsw_preemption_mode(), update graphics
context to set CTA premption mode if mode
NVGPU_COMPUTE_PREEMPTION_MODE_CTA is set
Also, define preemption modes in nvgpu-t18x.h
and use them everywhere
Remove old definitions of modes from gr_gp10b.h

Add CILP support for gp10b by defining below function
pointers (with detailed explanation)
pre_process_sm_exception()
- for CILP enabled channels, get the mask of errors
- if we need to broadcast the stop_trigger, suspend all SMs
- otherwise suspend only current SM
- clear hww_global_esr values in h/w
- gr_gp10b_set_cilp_preempt_pending()
- get ctx_id
- using sideband method, program FECS to generate
interrupt on next ctxsw
- disable and preempt the channel/TSG
- set cilp_preempt_pending = true
- clear single step mode
- resume current SM
handle_fecs_error()
- we get ctxsw_intr1 upon next ctxsw
- clear this interrupt
- get handle of channel on which we first
triggered SM exception
- gr_gp10b_clear_cilp_preempt_pending()
- set cilp_preempt_pending = false
- send events to channel and debug session fd
