We right now allocate a nvgpu managed syncpoint in c->sync and share
that with user space
But to avoid conflicts between user space and kernel space increments
allocate a separate "client managed" syncpoint for User space in c->user_sync
Add new API nvgpu_nvhost_get_syncpt_client_managed() to request a client managed
syncpoint from nvhost.
Note that nvhost/nvgpu do not keep track of MAX/threshold value of this syncpoint
Update gk20a_channel_syncpt_create() to receive a flag to indicate whether a
User space syncpoint is required or not
Unset NVGPU_SUPPORT_USER_SYNCPOINT for gp10b since we don't want to allocate
double syncpoints per channel on that platform
For gv11b, once we move to use user space submits, support for c->sync will be
dropped so we keep using only one syncpoint per channel

This reverts commit 0c46f8a5e112c08c172ee2c692832e1753ffbcce.
We should not support tracking of MAX/threshold value for syncpoint allocated
by user space
Hence revert this patch

The operations in struct nvgpu_sgt_ops have a scatter-gather list (sgl)
argument which is a void pointer. Change the type signatures to take
struct nvgpu_sgl * which is an opaque marker type that makes it more
difficult to pass around wrong arguments, as anything goes for void *.
Explicit types add also self-documentation to the code.
For some added safety, some explicit type casts are now required in
implementors of the nvgpu_sgt_ops interface when converting between the
general nvgpu_sgl type and implementation-specific types. This is not
purely a bad thing because the casts explain clearly where type
conversions are happening.

For some reason the GPU does not like the mappings created by the
DMA API for coherent sysmem buffers. But a plain vmap() does seem
to work. To work around this, when we are using coherent sysmem,
force the NO_KERNEL_MAPPING flag to on and then make a vmap() in
the nvgpu DMA API wrapper. The rest of the driver will be none the
wiser but will work as expected.
This problem is not understood yet but it is being tracked in bug
2040115. Once this bug is understood this WAR should either be
determined as necessary or reverted with an appropriate fix.

When using a coherent DMA API wee must make sure to program
any aperture fields with the coherent aperture setting. To
do this the nvgpu_aperture_mask() function was modified to
take a third aperture mask argument, a coherent setting, so
that code can use this function to generate coherent aperture
settings.
The aperture choice is some what tricky: the default version
of this function uses the state of the DMA API to determine
what aperture to use for SYSMEM: either coherent or
non-coherent internally. Thus a kernel user need only specify
the normal nvgpu_mem struct and the correct mask should be
chosen. Due to many uses of nvgpu_mem structs not created
directly from the DMA API wrapper it's easier to translate
SYSMEM to SYSMEM_COH after creation.
However, the GMMU mapping code, will encounter buffers from
userspace with difference coerency attributes than the DMA
API. Thus the __nvgpu_aperture_mask() really respects the
aperture setting passed in regardless of the DMA API state.
This aperture setting is pulled from NVGPU_VM_MAP_IO_COHERENT
since this is either passed in from userspace or set by the
kernel when using coherent DMA. The aperture field in attrs
is upgraded to coh if this flag is set.
This change also adds a coherent sysmem mask everywhere that
it can. There's a couple places that do not have a coherent
register field defined yet. These need to eventually be
defined and added.
Lastly the aperture mask code has been mvoed from the Linux
vm.c code to the general vm.c code since this function has
no Linux dependencies.
Note: depends on https://git-master.nvidia.com/r/1664536 for
new register fields.

Miscellaneous fixes for the sched code:
1. Make sure get_addr() on an SGL respects the use phys flag since
the runlist needs physical addresses when NVLINK is in use.
2. Ensure the runlist is contiguous. Since the runlist memory is
not virtually addressed the buffer must be physically contiguous.
3. Use all 64 bits of the runlist address in the runlist base addr
register (and related fields).

This patch does a couple of things. First it renames
NVGPU_DMA_COHERENT to NVGPU_USE_COHERENT_SYSMEM since the former
is somewhat ambiguous in meaning. The latter clearly states what
must happen: nvgpu needs to treat sysmem as coherent. This flag
does simply follow the state of the DMA API but there's no reason
to expect a casual reader of the code to know that when the DMA
API is coherent nvgpu must treat sysmem as coherent.
One thing to note though: when the dGPU is using PCIe and the
PCIe controller is coherent, it doesn't actually matter what we
do. However, we use this flag for determining how to make CPU
mappings in nvgpu_mem_begin() so this flag is still relevant for
the CPU side of things.
Next this patch adds a check in the core kernel GMMU mapping
routine to make sure that when the NVGPU_USE_COHERENT_SYSMEM flag
is set that the IO coherent flag is passed into the mapping code.
This is the primary fix that made NVLINK start working.
Finally the setting of the USE_COHERENT_SYSMEM flag and the
NVGPU_SUPPORT_IO_COHERENCE flag were set both for PCIe and for
iGPUs. The iGPU also must correctly match it's CPU mappings and
GPU mappings for proper operation.

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.

Use the nvgpu_info log facility instead of Linux-specific dev_info in
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.

(2) Nvlink interrupt handling
(3) Device initialization (IOCTRL, pll and clocks, device level intr)
(4) Falcon support for minion
(5) Minion load and bootstrapping
(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.
