cpufreq_driver_test_flags(9)

🎀 NAME 🎀

cpufreq_driver_test_flags — test the cpufreq driver’s flags against the ones you pass in. This is the cpufreq_driver_test_flags(9) page from the Kernel API Manual, and she’s literally here for a flag vibe check, bestie 💖

✨ SYNOPSIS ✨

okay so the signature is short and iconic:

bool cpufreq_driver_test_flags (u16 flags );

💅 ARGUMENTS 💅

• flags — the flags you’re testing against the current cpufreq driver’s flags. That’s the whole argument, periodt 🫶

🦋 DESCRIPTION 🦋

The way this function is giving “the driver is already there, right?” — it assumes that the driver is there, so callers must ensure that’s actually the case. No cap, that check is on the caller 😭✨
