π pvr_vm_get_dma_resv(9) π
okay so bestie, welcome to the pvr_vm_get_dma_resv page from the Kernel API Manual β yes, section 9, we're being fancy today β¨ this one's short and sweet and honestly kind of a flex, so let's get into it π«Ά
β¨ NAME β¨
pvr_vm_get_dma_resv β expose the dma_resv owned by the VM context, no cap π
πΈ SYNOPSIS πΈ
struct dma_resv * pvr_vm_get_dma_resv (struct pvr_vm_context *vm_ctx );
like, that's it. that's the whole vibe check. one function, one arg, one pointer back π₯
π ARGUMENTS π
vm_ctxβ the target VM context π― literally just the VM context you're pointing at, that's the whole job
π¦ DESCRIPTION π¦
so here's the tea β this one exists so that private BOs can share a dma_resv β and the reason is genuinely iconic: it's for faster fence updates β‘ like, shared resv = fewer headaches = speed. it's giving efficiency, it's giving teamwork, it's giving "we all share one resv and we're thriving" π§
β RETURN β
the dma_resv pointer π that's it, that's what you get back bestie π
π SEE ALSO π
okay this list is LONG, so buckle up β iykyk π everything here is (9) and lives in the Kernel file ./drivers/gpu/drm/imagination/pvr_vm.c:

like, the whole friend group showed up ππ«Ά go read them, they're all main characters too π
lowkey reminder: this is a kernel API page, so if you're here you're probably writing driver code β slay, but be careful out there π
and that's a wrap!! this page came from ./drivers/gpu/drm/imagination and it's dated October 2026 β mwah, bye bestie, go touch some fences (the GPU kind) ππβ¨
