PMU ucode is updated to include engine ID in the
PG messages sent from PMU to gpu driver.
Right now we were getting random values from the PMU ucode
as it uses ELPG msg structure without initializing.
It further causes incorrect values of ELPG state variables
maintained in the nvgpu driver.
PMU ucode update:

The value of NV_PERF_PMASYS_MEM_BUMP is different for Volta
and NVGPU_IOCTL_CHANNEL_CYCLE_STATS_SNAPSHOT_CMD_FLUSH did not
have correct behavior on GV11B due to that.
The patch adds an instance of css_hw_set_handled_snapshots
for Volta to fix that.
The patch also renames css_hw_set_handled_snapshots
to gk20a_css_hw_set_handled_snapshots to make it more clear
that the function is arch dependent.

gk20a_channel_dump_ref_actions. Also fix format types.
dev_info isn't defined anymore in this file and our version is preferred
anyway. Refcount tracking isn't compiled in by default, so this has went
unnoticed.

Add support for user fence updates i.e. increments added by user space
in pushbuffer directly
Add a submit IOCTL flag NVGPU_SUBMIT_GPFIFO_FLAGS_USER_FENCE_UPDATE to indicate
if User has added increments in pushbuffer
If yes, number_of_increment value is received in fence.value from User
If User is adding increments in the pushbuffer then we don't need to do any job
tracking in the kernel
So fail the submit if we evaluate need_job_tracking to true and
FLAGS_USER_FENCE_UPDATE is set
User is responsible for ensuring all pre-requisites for a fast submit and to
prevent kernel job tracking
Since user space adds increments in the pushbuffer, just handle the threshold
book keeping in kernel.

(6) Link initialization and DL PROD settings
(7) Device Interface init (and switching HSHUB to nvlink)
(8) HS set/get mode for both link and sublink
(9) Topology discovery and VBIOS settings.
(10) Ensures we get physical contiguous memory when Nvlink is enabled
This driver includes a hack for the current single dev/single link limitation.

READ_ONLY flag for dma API is a Tegra specific API. We use it only
to prevent accidental writes to non-secure ACR bootloader. Its use is
marginal, so remove the flag.

The hw semas in a sema pool are stored in a list. All elements in this
list are freed in a loop when a semaphore pool is destroyed. However,
each hw sema is always owned by a channel, and each such channel frees
its hw sema during channel closure before putting a ref to the VM which
holds a ref to the sema pool, so the lifetime of all the hw semas is
shorter than that of the pool and this list is always empty when freeing
the pool. Delete the list and this freeing loop.
Meanwhile delete also the nr_incrs member in nvgpu_semaphore_int that is
never accessed.

Updated subctx pdb info for all instblks created.
Earlier subctx pdb info was getting updated during instblk
commit. But some instblks like pmu instblk are never committed.
Missing subctx pdb info in instblk is creating issues accessing
subctx info. So, by filling subctx pdb info during instblk
creation fixed all these issues.
Also as part of re-org of the function gv11b_init_subcontext_pdb,
moved setting subctx info in ram_in_engine_wfi_veid_w() to
channel_gv11b_setup_ramfc.

Add User space API NVGPU_AS_IOCTL_GET_SYNC_RO_MAP to get read-only syncpoint
address map in user space
We already map whole syncpoint shim to each address space with base address
being vm->syncpt_ro_map_gpu_va
This new API exposes this base GPU_VA address of syncpoint map, and unit size
of each syncpoint to user space.
User space can then calculate address of each syncpoint as
syncpoint_address = base_gpu_va + (syncpoint_id * syncpoint_unit_size)
Note that this syncpoint address is read_only, and should be only used for
inserting semaphore acquires.
Adding semaphore release with this address would result in MMU_FAULT
Define new HAL g->ops.fifo.get_sync_ro_map and set this for all GPUs supported
on Xavier SoC

The GPU has multiple different operating modes in respect to IOMMU'ability.
As such there needs to be a clean way to tell the driver whether it is
IOMMU'able or not. This state also does not always reflect what is possible:
all becasue the GPU can generate IOMMU'ed memory requests doesn't mean it
wants to.
The nvgpu_iommuable() API has now existed for a little while which is a
useful way to convey whether nvgpu should consider the GPU as IOMMU'able.
However, there is also the g->mm.bypass_smmu flag which used to be able to
override what the GPU decided it should do. Typically it was assigned
the same value as nvgpu_iommuable() but that was not necessarily a
requirment.
This patch removes all the usages of g->mm.bypass_smmu and instead uses the
nvgpu_iommuable() function. All places where the check against
g->mm.bypass_smmu have been replaced with nvgpu_iommuable(). The code
should now be much cleaner.
Subsequently other checks can also be placed in the nvgpu_iommuable()
function. For example, when NVLINK comes online and the GPU should no
longer consider DMA addresses and instead use scatter-gather lists
directly the ngpu_iommuable() function will be able to check the state of
NVLINK and then act accordingly.
