Motivation

#7360 added a module-level import fcntl to
build_tools/print_driver_gpu_info.py. fcntl is a Unix-only stdlib module,
so the Driver / GPU sanity check step (which runs this script) now crashes at
import time on every Windows CI runner:

Traceback (most recent call last):
  File "...\build_tools\print_driver_gpu_info.py", line 23, in <module>
    import fcntl
ModuleNotFoundError: No module named 'fcntl'

That fails the Windows sanity job and skips every downstream Windows component
test. The only use of fcntl is in _get_kfd_version(), which reads the KFD
ioctl version from /dev/kfd and is only reached on the Linux path -- Windows
should never have imported the module.

ISSUE ID: N/A (regression from #7360)

Technical Details

Move import fcntl out of module scope into _get_kfd_version(), its sole user.
That function only runs on Linux, so the Unix-only import now happens only where
it is valid. No functional change on Linux.

Test Plan

• Import + run print_driver_gpu_info.py on Windows Server 2025, before vs after.
• Confirm the Linux KFD path is unchanged (import still resolves inside the
  function that uses it).

Test Result

• Windows, before: ModuleNotFoundError: No module named 'fcntl' at import.
• Windows, after: script imports and runs to completion (exit 0), taking the
  hipInfo.exe path and skipping the Linux-only KFD block.
• The equivalent pre-ci: gate on KFD IOCTL version in driver/GPU sanity check #7360 sanity path (identical apart from this import) already
  passes Driver / GPU sanity check and runs the origami gfx1201 component test
  green on a Windows R9700 runner.

Would have preferred a revert instead of a fix-forward.

This looks correct though, so okay. (tested on my Windows machine too)

Validated end-to-end on a Windows gfx1201 (Radeon AI PRO R9700) runner by dispatching test_artifacts.yml with the harness checkout pointed at this commit (repository=amd-justchen/TheRock, ref=efff817):

https://github.com/ROCm/TheRock/actions/runs/33566391044 -> success

• Before (at f3e9941, current main): the Driver / GPU sanity check step crashes at import with ModuleNotFoundError: No module named 'fcntl', failing sanity and skipping all Windows components.
• After (this commit): the same step runs hipInfo.exe and passes:

HEAD is now at efff817 fix(ci): guard Unix-only fcntl import in driver/GPU sanity check
=== Sanity check: driver / GPU info ===
=== hipInfo.exe ===
Name:        AMD Radeon AI PRO R9700
gcnArchName: gfx1201

Sanity check passed and the origami component test passed (overall run green).

Fair enough! My agent happened to have discovered it while trying to get a new runner up. Seems like a reasonable fix.

Given comments about Windows testing passing and CI showing Linux GPU tests passing will merge this.
