π₯ DESCRIPTION π₯
okay so here's what she actually does, and it is a lot, ngl:
- sets up the TLBs (yes ma'am, the translation lookaside buffers)
- programs the page tables for VMID0
- sets up the hardware for VMIDs 1-15, which are allocated on demand β they don't all show up at once, they get invited as needed π
- sets up the global locations for the LDS, the GDS, and the GPUVM for FSA64 clients (CIK)
and then, the vibe check: she returns 0 for success, and errors for failure. simple as that, fr fr. π
