If platform probe fails as a result of DEFER_PROBE, it should be
reported as dev_info instead of dev_err.

It's technically possible for a thread to exit without first calling
nvgpu_thread_stop() in another, so mark the thread exit status from the
thread after it has finished instead of in nvgpu_thread_stop(). Do this
by starting the thread as a proxy function which calls the actual thread
function and then sets the flag.
Also, add a new flag to actually signify the running state because the
thread->task going null abruptly would break nvgpu_thread_stop().
This does not guarantee that the kernel thread itself has stopped, but
the function which can be considered as an "nvgpu thread" will be.

In order to perform timestamps correlation for FECS
traces, we need to collect GPU / GPU timestamps
samples. In virtualization case, it is possible for
a guest to get GPU timestamps by using read_ptimer.
However, if the CPU timestamp is read on guest side,
and the GPU timestamp is read on vm-server side,
then it introduces some latency that will create an
artificial offset for GPU timestamps (~2 us in
average). For better CPU / GPU timestamps correlation,
Added a command to collect all timestamps on vm-server
side.

To make do_idle work when nvgpu is built as a module, reverse the order
of call dependencies for do_idle. Don't provide visible
gk20a_do_{idle,unidle}() functions for the kernel but instead call the
kernel for registering and unregistering pointers to them when the
driver loads and unloads.
Refactor the internal __gk20a_do_{idle,unidle} functions to take a
struct gk20a * instead of struct device *, and use the callback api for
providing that g instead of retrieving the plat device from device tree.

To support deterministic channels even with platforms where railgating
is supported, have each deterministic-marked channel hold a power
reference during their lifetime, and skip taking power refs for jobs in
submit path for those.
Previously, railgating blocked deterministic submits in general because
of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time
and more significantly because the gpu may need turning on which takes a
nondeterministic and long amount of time.
As an exception, gk20a_do_idle() can still block deterministic submits
until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize
needs do_idle, which conflicts with deterministic channels' requirement
to keep the GPU on. This is documented in the ioctl header now.
Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always
set in the gpu characteristics now that it's supported. The only thing
left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is
the sync framework.
Make the channel debug dump show which channels are deterministic.

Split handling of stalling interrupt to Linux specific chip
agnostic and OS independent chip specific parts.
Linux specific chip independent part contains handler for ISR
and passing the control to a bottom half worker. It uses the new MC
HALs intr_nonstall (query interrupt status), intr_nonstall_pause
(pause interrupts), intr_nonstall_resume (resume interrupts), and
is_intr1_pending (query per-engine interrupt bit).
MC HAL isr_nonstall is removed, because its work is now handled in
chip independent code.

split it in two bits into the enabled() API:
Add NVGPU_MM_HONORS_APERTURE bit, which is the same as vidmem_is_vidmem
with its original meaning, and use it to test which aperture bits to
write to hardware.
Add NVGPU_MM_UNIFIED_MEMORY bit, which has the opposite meaning: that
the GPU shares the SoC memory. When this flag is false, the GPU has its
own local video memory.

common/linux/debug_ce.c
common/linux/debug_fifo.c
common/linux/debug_gr.c
common/linux/debug_mm.c
common/linux/debug_allocator.c
common/linux/debug_kmem.c
common/linux/debug_pmu.c
common/linux/debug_sched.c
Add corresponding header files for above modules too
And compile all of above files only if CONFIG_DEBUG_FS is set
Some more details of the changes made
- Move and rename gk20a/debug_gk20a.c to common/linux/debug.c
- Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h
- Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call

- Update all debug APIs to receive struct gk20a as parameter

- Update API gk20a_dmabuf_get_state() to receive struct gk20a

- Remove "gk20a/platform_gk20a.h" include from HAL files

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.

Split handling of stalling interrupt to Linux specific chip
agnostic and OS independent chip specific parts.
Linux specific chip independent part contains handler for ISR
and passing the control to a bottom half. It uses the new MC HALs
intr_stall (query interrupt status), intr_pause (pause interrupts)
and intr_resume (resume interrupts).
MC HAL isr_stall now returns void and gets called in thread context
and thus remove isr_thread_stall and replace the implementation with
isr_stall.

This function is an internal function to the VM manager that allocates
virtual memory space in the GVA allocator. It is unfortunately used in
the vGPU code, though. In any event, this patch cleans up and moves the
implementation of these functions into the VM common code.

The timeout parameter to NVGPU_COND_WAIT()
was passed directly to wait_event_timeout(), which takes jiffies.
Also allows zero timeout to disable timeout.
The return value of NVGPU_COND_WAIT() was defined in a way specific
to how Linux wait_event_() calls work. Replace that with proper error
reporting and change the callers to check against error codes.

PG419 board had been reworked to swap I2C_B and I2C_C
(in order to solve PL issues). As a result, on this
board we now use a different I2C port than on PG418.
Remove support for non-reworked boards: VBIOS version
must be at least .56
Add I2C port in platform data.

The vm_reserve_va_node struct is essentially a special VM area that
can be used for sparse mappings and fixed mappings. The name of this
struct is somewhat confusing (as node is typically used for list
items). Though this struct is a part of a list it doesn't really
make sense to call this a list item since it's much more. Based on
that the struct has been renamed to nvgpu_vm_area to capture the
actual use of the struct more accurately.
This also moves all of the management code of vm areas to a new file
devoted solely to vm_area management.
Also add a brief overview of the VM architecture. This should help
other people follow along the hierachy of ownership and lifetimes in
the rather complex MM code.

This patch begins splitting out the VM implementation from mm_gk20a.c and
moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary
because the VM code has two portions: first, an interface for the OS
specific code to use (i.e userspace mappings), and second, a set of APIs
for the driver to use (init, cleanup, etc) which are not OS specific.
This is only the beginning of the split - there's still a lot of things
that need to be carefully moved around.

This patch begins the major rework of the GPU's virtual memory manager
(VMM). The VMM is the piece of code that handles the userspace interface
to buffers and their mappings into the GMMU. The core data structure is
the VM - for now still known as 'struct vm_gk20a'. Each one of these
structs represents one addres space to which channels or TSGs may bind
themselves to.
The VMM splits the interface up into two broad categories. First there's
the common, OS independent interfaces; and second there's the OS specific
interfaces.
OS independent
--------------
This is the code that manages the lifetime of VMs, the buffers inside
VMs (search, batch mapping) creation, destruction, etc.
OS Specific
-----------
This handles mapping of buffers represented as they are represented by
the OS (dma_buf's for example on Linux).
This patch is by no means complete. There's still Linux specific functions
scattered in ostensibly OS independent code. This is the first step. A
patch that rewrites everything in one go would simply be too big to
effectively review.
Instead the goal of this change is to simply separate out the basic
OS specific and OS agnostic interfaces into their own header files. The
next series of patches will start to pull the relevant implementations
into OS specific C files and common C files.
