dm_test_crtc...nk_full_path(9)
β¨ NAME β¨
dm_test_crtc_enable_vblank_full_path β this test is literally about checking that the enable path runs to completion. Thatβs the whole assignment, bestie. π
okay so this page is dm_test_crtc...nk_full_path(9) from the Kernel API Manual, and the actual function name is the full one up there β sheβs the main character of this page. π
πΈ SYNOPSIS πΈ
void dm_test_crtc_enable_vblank_full_path (struct kunit *test );
thatβs the signature, character for character β no edits, no βfixing,β periodt. β¨
π ARGUMENTS π
testβ the KUnit test context. thatβs all she wrote.
π₯ DESCRIPTION π₯
okay so picture this: thereβs a configured CRTC on a VRR-capable DC, and both the crtc/pageflip IRQ sources are armed. In that setup, the enable path walks the vupdate-irq branch β because VRR is active and OTG is unassigned, so it returns early there. Along the way it acquires both IRQ references and completes with no vblank workqueue queued. thatβs the whole vibe check, and the test is confirming the enable path runs all the way to completion. π¦
