✨ xe_assert(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's about xe_assert β€” the debug-only vibes check for your Xe driver. let's get into it 🫢


πŸ’– NAME πŸ’–

xe_assert β€” warn if condition is false when debugging.

like, it literally just goes "hey bestie, that's not true" but only when you're in debug mode πŸ’…


🌸 SYNOPSIS 🌸

xe_assert (xe , condition );

that's it. that's the whole call. two things in, chaos (or nothing) out ✨


πŸŽ€ ARGUMENTS πŸŽ€

  • xe β€” the struct xe_device pointer to which condition applies. it's giving "main character device energy" β€” the condition is about this device specifically πŸ‘‘
  • condition β€” the condition to check. the thing you're claiming is true. if it's not, we're gonna have a whole moment 😭

πŸ¦‹ DESCRIPTION πŸ¦‹

so xe_assert uses drm_WARN to emit a warning and print additional information that could be read from the xe pointer if the provided condition is false. like it doesn't just yell β€” it also dumps the extra context it can pull from xe, which is honestly so thoughtful of it πŸ₯Ή

but β€” and this is the important part, no cap β€” contrary to drm_WARN, xe_assert is effective only on debug builds. CONFIG_DRM_XE_DEBUG must be enabled. like, if that's not on, this thing is literally just a decorative little function call, living its truth, doing nothing πŸ’€

also it cannot be used in expressions or as a condition. nope. not that kind of macro. it's a statement-ass vibe, not a "plug me into an if" vibe. please don't try it πŸ™ˆ

bestie reminder: debug-only + not usable in expressions or as a condition. that's the whole personality. respect it.

see Xe Asserts_ for general usage guidelines β€” that's the sacred text for how to use these things properly, iykyk πŸ“–
