xe_gt_assert(9)

💅 xe_gt_assert(9) — the kernel API manual, bestie edition ✨

okay so this is xe_gt_assert, from the Kernel API Manual, and it's genuinely one of those tiny functions that eats. it's a debug-build warning machine, and once you get the vibe you'll be obsessed 🫶

---

🌸 NAME 🌸

xe_gt_assert — warn if condition is false when debugging. that's it. that's the whole job. no cap ✨

---

🦋 SYNOPSIS 🦋

xe_gt_assert (gt , condition );

literally just those two things and you're off 🎀

---

💖 ARGUMENTS 💖

• gt — the struct xe_gt pointer that the condition applies to. it's giving "context, but make it graphics tile" 👑
• condition — the condition to check. the thing you're like "this better be true bestie" about 💀

---

🌈 DESCRIPTION 🌈

so here's the tea: xe_gt_assert uses drm_WARN to emit a warning, and it also prints extra information that could be safely read from the gt pointer — if the condition you provided turns out to be false. so you get the warning AND the receipts 🔥

but wait, because this is the part where you need to pay attention, bestie 😭 contrary to drm_WARN, xe_gt_assert is effective only on debug builds — CONFIG_DRM_XE_DEBUG must be enabled — and it cannot be used in expressions or as a condition. like, it's not that kind of girl. it's a statement, not a value. periodt 💅

vibe check warning: if CONFIG_DRM_XE_DEBUG isn't enabled, this thing is lowkey just vibing and doing nothing. also do NOT try to sneak it into an expression or a condition — it literally says it cannot be used there 🚫

for the general usage guidelines, go see Xe Asserts. she's the main character, this is the spin-off ✨
