clk_arb.h and gk20a.h has circular dependencies to each other. This is
removed by forward declaring struct gk20a in clk_arb.h and removing the
header gk20a.h from clk_arb.h and similarly forward declaring struct
nvgpu_clk_arb in gk20a.h and removing the header clk_arb.h from gk20a.h
alongwith putting headers in every execution unit which calls clk_arb.h
related methods.

once gpu is powered off i.e. power_on set to false, nvgpu isr
does not handle stall/nonstall irq. Depending upon state
of gpu, this can result in either of following errors:
1) irq 458: nobody cared (try booting with the "irqpoll" option)
2) "HSM ERROR 42, GPU" from SCE if it detects that an interrupt is
not in time.
Fix these by masking all interrupts just before gpu power off
as nvgpu won't be handling any irq anymore.
While masking interrupts, if there are any pending interrupts,
then report those with a log message.

In the current code, gk20a.h includes io.h which gets directly included
in a lot of other files. io.h contains methods which uses a struct
gk20a as a parameter leading to a circular dependency between io.h
and gk20a.h. This can be mitigated by removing io.h from gk20a.h as
part of larger effort to moving gk20a.h to nvgpu/gk20a.h

In order to avoid the circular dependencies,
rearrange the static inline functions from
gk20a.h file.
Moved gk20a_gr_flush_channel_tlb function to
gr_gk20a.c and removed the #include gr_gk20a.h
from gk20a.h
Added a helper function utils.h to
move all generic static inline functions which
have no reference to gpu related structures.
ptimer related functions are moved to
ptimer.h
Implementations for as and pmu are moved to
corresponding files.

Since ltc state is lost with rail gate, this setting is

- adds static tpc-powergating through sysfs.
- active tpc count will remain till the GPU/systems is not booted again.
- tpc_pg_mask can be written only after GPU probe finishes and
GPU boot is triggered.
Note:
To be able to use this feature, we need to change boot/init
scripts of the OS(used with nvgpu driver) to write to sysfs nodes before
posting discover image size query to FECS.

This reverts commit 0b02c8589dcc507865a8fd398431c45fbda2ba9c.
Originally change was reverted as it was making ap_compute test on
embedded-qnx-hv e3550-t194 fail. With fixes related to replacing tsg
preempt with runlist preempt during teardown, preempt timeout set to
100 ms (earlier this was set to 1000ms for t194 and 3000ms for legacy
chips) and not issuing preempt timeout recovery if preempt fails, helped
resolve the issue.

Moved gv11b_detect_ecc_enabled_units function
from gv11b.c to gr_gv11b.c, as this is being
used only in gr_gv11b file.
In order to avoid GR code touching fuse registers,
as it need to include fuse HW headers in GR code,
introduced two fuse HALs which are being called
from GR code. is_opt_ecc_enable for checking
whether ecc enable bit is set in fuse register
and is_opt_feature_overide_disable for checking
whether feature override disable bit is set in
fuse register.
Initialized fuse HAL functions for chips that
make use of those HAL functions.

context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.

The biggest remaining Linuxism in the submit path is the
copy_from_user() calls for reading the gpfifo entries to the HW-visible
buffer. Abstract away the copy of one such segment starting at some
offset and keep the wraparound logic and vidmem proxy in the core submit
path.

Add remove_gr_sys() op to gpu_ops to reverse steps
done in create_gr_sysfs().
Make gv11b_tegra_remove() specific to gv11b instead
to properly remove sysfs nodes. This also helps in
having gv11b specific remove steps.
Also, update platform remove function of dGPU i.e.
nvgpu_pci_tegra_remove() to remove sysfs nodes. This
adds parity with iGPU platform remove.

VBIOS link_disable_mask should be sufficient to find the connected

DT node is used for different dGPUs connected over PCIE. Remove the
DT parsing of link id and use HAL to get link_mask based on the GPU.

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.
