dm_test_crt...x_after_skip(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_crtc_handle_crc_irq_dprx_after_skip(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the dm_test_crt...x_after_skip(9) page 🎀 (yes the title is truncated in the header, that's just how it is, she's mysterious like that). We're in the Kernel API Manual today and this is a KUnit test function, so buckle up 🦋

✨ NAME ✨

dm_test_crtc_handle_crc_irq_dprx_after_skip — literally a test for the DPRX post-skip exit. That's the whole vibe 💅

🌸 SYNOPSIS 🌸

void dm_test_crtc_handle_crc_irq_dprx_after_skip (struct kunit *test );

no cap, that's it, that's the whole signature 🫶

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. she's the main character holding the whole test together 👑

💖 DESCRIPTION 💖

So what does this icon actually do? She verifies that enabled non-CRTC CRC sources do not call into DC CRC reads after the initial skip window. Periodt. 🔥

Like, the skip window happens first, and then we check nobody's sneaking in extra DC CRC reads from a non-CRTC source — that's the whole point of the test, and honestly? iconic behaviour 🌈

ngl this is a test asserting a negative — "do not call into" — so if you're reading this hoping for a happy little call diagram, bestie, that's not what she's giving 🙈

🦋 SEE ALSO 🦋

First up, the kernel file she lives in 💜

  • Kernel file
  • ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_crc_test.c

and then the whole friend group — her siblings in the same test family, all of them, no skipping:

and that's the whole page, bestie, you ate that 🍓

💀 sign-off time: this lil masterpiece comes from ./drivers/gpu/drm/amd/display/... and the footer says October 2026 with the header tag dm_test_crt...x_after_skip(9). go forth and test, queen 🧚💜
