💅 dm_test_handle_hpd_rx_irq_automated_test(9) ✨

okay so bestie, this page is from the Kernel API Manual, and it’s all about dm_test_handle_hpd_rx_irq_automated_test(9). It’s giving “tiny KUnit test, big automated-test-path energy.” 🫶

🌸 NAME 🌸

dm_test_handle_hpd_rx_irq_automated_test — Test HPDRX automated-test path. Yep, that’s the whole name, and it’s iconic. 💖

💖 SYNOPSIS 💖

void dm_test_handle_hpd_rx_irq_automated_test (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. This is the little test-stage where everything happens, no cap. 🎀

🦋 DESCRIPTION 🦋

okay so here’s the tea: the AUTOMATED_TEST device-service bit must schedule offload work and jump to out before the allow-hpd-rx-irq checks. That’s the exact automated-test path behavior this test is checking, and it’s lowkey the main character of the whole page. ✨

Bestie, the order matters: schedule offload work and hit out first, then the allow-hpd-rx-irq checks. The test is literally there to make sure that jump happens before those checks cut in. 💅
