GPU average and input power backends report a mix of whole watts,
milliwatts, Q24.8 watts and decimal-packed fractions. Q24.8 is inherited
from the legacy PowerPlay sensor format. Milliwatts are a more natural unit
for the hwmon and pm_info consumers in amdgpu_pm.c. A common decoder cannot
distinguish these formats, and converting native milliwatts through Q24.8
also loses precision.
Use milliwatts as the internal unit across all PPT and PowerPlay backends.
Decode Q24.8 only at the legacy smu7 input boundary and encode it only for
the raw amdgpu_sensors debugfs interface. This gives hwmon, pm_info and the
sensor ioctl one unambiguous unit while preserving the format used by UMR.

Updates PPSMC_MSGs and set/get functions for gathering GFXOFF logs
on Van Gogh. Logs are now gathered live rather than starting then
stopping logging and reading an average value afterwards. This is
in accordance to changes made in PMFW.
In regards to messageID 0x52, the old interface uses a start/stop
parameter, and the new one doesn't. The firmware is checked to
determine which method to use.
v2: added firmware guard to new interface, old interface kept as
fallback

(cherry picked from commit 482e2cadea)
v3:
improve the coding style.
v2:
use debugfs_create_x64 and debugfs_create_x8 to create node.
v1:
1. Add guest driver CUID support
2. Do not expose vf index(variable "fcn_idx") to customers,
replace the fcn_idx with pad.
Only expose the unitid to customers.
background:
Change fcn_idx to pad, VF index won't expose to guest vm.
Introduce a new unitid field as the VF identifier to replace the VF index:
1).unitid is assigned by the host driver
2).It is delivered to the guest via the pf2vf message
3).The application or umd can retrieve united from the sysfs node

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Decouple the amdgpu fence from the amdgpu_job structure.
This lets us clean up the separate fence ops for the embedded
