vmw_validation_preload_bo(9)
π vmw_validation_preload_bo β the kernel API manual, but make it make sense π
okay so bestie, we're looking at vmw_validation_preload_bo from the Kernel API Manual β it's a (9) page, which is the kernel dev section iykyk. Let me break it down for you, no cap. β¨
πΈ NAME πΈ
vmw_validation_preload_bo β literally just warms up the validation memory allocator so your girl is ready for a call to vmw_validation_add_bo(). it's giving "pregame before the pregame", fr fr. π
π¦ SYNOPSIS π¦
int vmw_validation_preload_bo (struct vmw_validation_context *ctx );
that's the whole signature, bestie. int in, ctx pointer out there doing main character energy. π
β ARGUMENTS β
ctxβ pointer to the validation context. that's it. that's the argument. π«Ά
π₯ DESCRIPTION π₯
ok so here's the tea: iff this function returns successfully β and yes it literally says iff, the math-queen "if and only if" β then the next call to vmw_validation_add_bo is guaranteed not to sleep. like, zero naps. fully awake. slay. π΄π«
but listen β an error is not fatal. it just voids the guarantee. so it's giving "no big deal, but the vibe check failed". not the end of the world, just no promises anymore. π
π RETURN π
- Zero if successful β¨
-EINVALotherwise π
that's the whole return contract, periodt.

the lore continues in the kernel file ./drivers/gpu/drm/vmwgfx/vmwgfx_validation.c, and also these icons:

that's the whole friend group, bestie. go say hi. π§π
and the source? it lives at ./drivers/gpu/drm/vmwgfx, version/date stamp says October 2026 β so like, future icon behavior. anyway, that's the page, ily, go read the rest of the validation saga π
