Currently, NVGPU must modify RM/PMU defined common super surface

as NVGPU cannot include directly RM/PMU defined struct due to number

SSMD lookup table which is part of PMU super surface buffer & is
always first member of PMU super surface data struct for easy access,
SSMD lookup table will be copied to PMU super surface SSMD offset by

2. Read the device tree pci node to know about nvlink topology

4. Register nvlink_device and nvlink_link with the core-driver.
nvlink probe returns -ENODEV when nvlink is not supported.
Nvlink is not supported in two cases:
1. There is no nvlink IP on the Tegra SoC which is denoted by
CONFIG_TEGRA_NVLINK or
2. The pci device tree node does not have "nvidia,nvlink" child
node needed to describe nvlink topology.
Any negative return value other than -ENODEV denotes failure in

The device_info table is an array of registers which contain engine
specific data for engines like CE, graphics, nvdec, ioctrl etc.
These registers contain data like intr_enum, reset_enum, pri_base
and so on. The Top unit would include HAL to parse this table and
get data for a particular engine.
Some engines like CE have multiple entries in the device_info table
corresponding to each instance of the engine. Prior to Pascal, each
instance of an engine was denoted by different engine type.
For example in GM20B, there are engine types like COPY_ENGINE0,
COPY_ENGINE1 and so on. In Pascal and chips beyond, a new field
called "inst_id" is added and the engine_type is kept the same.
For example in GP10B, all copy engine entries have same engine type
i.e ENGINE_LCE, but different inst_ids. So for Pascal and chips
beyond, add HAL to get number of entries corresponding to an engine
type.The "get_device_info" HAL will parse a specific instance
of the engine using inst_id argument

such should be its own unit. To do this a new source file has been

These are the facade APIs to abstract the actual details of how any
given nvgpu_sgt is actually implemented.
An abstract unit - nvgpu_sgt_os - was also defined. This unit
exists solely for the nvgpu_sgt unit to call so that the OS
specific nvgpu_sgt_os_create_from_mem() API can be moved from the
common nvgpu_sgt unit. Note this also updates the name of what the

Add two new sub-directories under MM: gmmu and allocators.
The allocators directory is for all the allocator code we have.
There's a fair amount and as such could be considered a component
with a bunch of sub-units.
The new GMMU directory will contain the GMMU component (which used to
be a single unit). The new GMMU component is comprised of the
page_table and pd_cache units. Also when we migrate the chip specific
GMMU code out of mm_gk20a.c and mm_gp10b.c it will be placed in this
new GMMU directory.

gk20a.c is used only in Linux build. It's in theory common code, but
in practice implements OS specific policies. Also implement
os/posix/gk20a.c to implement gk20a_init_gpu_characteristics(),
gk20a_get() and gk20a_put() which are called from common code.

All the netlist parsing code is currently under GR unit, but netlist
ucode parsing does not really have any logical dependency to GR
Hence separate out a new unit common/netlist/ that parses the netlist
image and stores/exposes its content through netlist_vars structure
Structure nvgpu_netlist_vars is added to structure gk20a
Move netlist parsing code to common/netlist/netlist.c and chip
specific files to common/netlist/netlist_<chip>.c
Move simulation netlist parsing to common/netlist/netlist_sim.c
Rename g.ops.gr_ctx HAL to g.ops.netlist
Rename all the exported structures to be in the form of nvgpu_*
Rename all exported functions to be in the form of nvgpu_netlist_*()
Add netlist initialization to GPU boot path, and add deinitialization
to GPU remove path

Add nvgpu_memcpy/nvgpu_memcmp which are MISRA-compliant versions
(Rule 21.15) of memcpy/memcmp.
Also convert some clk/gr calls over to use the new routines;
all of the remaining calls will be converted in subsequent patches.
