dm_test_get_...db_supported(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so this is dm_test_get_amd_vsdb_supported — and what it does is test that a non-zero VSDB version is reported. that's it, that's the whole gig 💅 (also, hi, this is page dm_test_get_...db_supported(9) from the Kernel API Manual, welcome to the function-level portion of the group chat 🫶)

🌸 SYNOPSIS 🌸

void dm_test_get_amd_vsdb_supported (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. yes bestie, that's the whole argument list, it's one (1) pointer and she's carrying the entire test 🧚

💅 DESCRIPTION 💅

so here's the vibe: the display info's VSDB version and its replay mode get copied out 📋, and if that version comes back non-zero, that's what reports support ✨. non-zero version = supported, periodt.

that's literally the entire check. no cap. the test grabs the values, peeks at the version, and goes "yep, we got support" when it's not zero 🔥

lowkey important to note: this is the supported case, not the unsupported one — the unsupported side lives in dm_test_get_amd_vsdb_unsupported(9) and she is a different page, go say hi 🌸
