okay so bestie, welcome to the Kernel API Manual entry for xe_pxp_pm_suspend(9) — yes the whole page is named after the function, iconic behavior honestly 💅

✨ NAME ✨

xe_pxp_pm_suspend — gets PXP all cozy and ready for HW suspend 🫶

✨ SYNOPSIS ✨

int xe_pxp_pm_suspend (struct xe_pxp *pxp );

✨ ARGUMENTS ✨

• pxp — the xe->pxp pointer, and heads up bestie, it will be NULL if PXP is disabled 🙈

✨ DESCRIPTION ✨

so what does it actually do? it makes sure all PXP actions have completed — like, fully finished, no stragglers — and then it invalidates all PXP queues and objects before we go into a suspend state 💤 no cap, that's the whole vibe. clean slate before naptime, periodt.

✨ RETURN ✨

• 0 if successful ✨
• a negative errno value otherwise 😭

ngl bestie, just check the return value. it's giving "trust me bro" if you don't.
