[PATCH v6 0/4] lib: Add generic platform filtering framework for IGT

From: Vitaly Prosyak <[email protected]>

This series introduces a vendor-agnostic platform filtering framework
for IGT that allows tests to automatically skip based on hardware
platform rules, without requiring manual igt_skip() calls in each
subtest.

The framework uses a callback-based design (platform_filter_ops) so
any vendor can plug in their own backend without modifying the core.
AMD support is included as the first backend.

Patch overview:
  1/4 - lib: Generic framework (platform_filter_ops interface,
        built-in/config/env priority tiers, automatic subtest hook)
  2/4 - lib/amdgpu: AMD backend (ASIC identification, name table,
        built-in skip rules, amd_platform_filter_init())
  3/4 - lib/igt_core: Hook into __igt_run_subtest() for automatic
        filtering without manual igt_platform_require() calls
  4/4 - docs: Platform filtering usage guide
