pvr_mmu_op_...sync_partial(9)

💅 pvr_mmu_op_context_sync_partial(9) — the "Kernel API Manual" glow-up ✨

okay so bestie, welcome to the Kernel API Manual page for pvr_mmu_op_context_sync_partial 🎀 this one's short and sweet and honestly kind of a diva move — it's the "sync some of my page tables, not all of them" function. iykyk 💅

🌸 NAME 🌸

pvr_mmu_op_context_sync_partial — triggers a sync of some or all of the page tables that a MMU op context is pointing at. like, girly said "i don't need the whole flush, just this bit" 💖

✨ SYNOPSIS ✨

void pvr_mmu_op_context_sync_partial (struct pvr_mmu_op_context *op_ctx
, enum pvr_mmu_sync_level level );

no cap, that's the whole signature — returns void, so no status to check, she just does it 🫶

🦋 ARGUMENTS 🦋

  • op_ctx — the target MMU op context. this is the main character of the whole operation 👑 it's a struct pvr_mmu_op_context * and it's the thing holding the record of everything that needs syncing.
  • level — the requested page table level to sync up to, inclusive. that "inclusive" is doing real work here, ngl — the level you name gets synced too, fr fr 🔥 it's an enum pvr_mmu_sync_level.

💜 DESCRIPTION 💜

so here's the tea, bestie 🍓 — this function is the picky one. it syncs page tables, but only up to a level you choose. and there are two little rules layered on top of that, because of course there are 😭

rule one, the clamp: if level is greater than the maximum level that op_ctx has recorded as requiring a sync operation, then only that previously recorded maximum gets used. translation: you can't ask for a bigger sync than what's actually been flagged as needing one — the function just quietly caps you at the recorded max 🙈

rule two, the reset: additionally, if level is greater than or equal to the maximum level recorded by op_ctx as requiring a sync operation, that maximum level gets reset — because a full sync is gonna happen anyway 💀 and heads up: that outcome is equivalent to calling pvr_mmu_op_context_sync. so if you're going all the way up, just know you're getting the full-sync behaviour, no half measures 🎀

ngl, the > vs >= distinction is the whole personality of this function — greater than gets clamped, greater than or equal gets clamped and resets the recorded max. don't sleep on that equality sign bestie ✨

🌈 SEE ALSO 🌈

like, the entire PowerVR virtual memory universe, honestly. she's connected to everyone 💅 first up, the source file:

  • Kernel file ./drivers/gpu/drm/imagination/pvr_mmu.c

and the whole friend group 🔥

✨ that's the whole page, bestie ✨ straight outta ./drivers/gpu/drm/imagination, dated October 2026, and the page itself is pvr_mmu_op_...sync_partial(9). go sync something partially, you absolute icon 💖🎀🦋
