imgu_mmu_map(9)
β¨ NAME β¨
Okay so bestie, welcome to imgu_mmu_map β straight outta the Kernel API Manual β and it does exactly one iconic thing: it maps a buffer to a physical address. That's it. That's the vibe. π
πΈ SYNOPSIS πΈ
int imgu_mmu_map (struct imgu_mmu_info *info , unsigned long iova ,
phys_addr_t paddr , size_t size );
Like, look at her. Four arguments, one int return, zero chill. π
π¦ ARGUMENTS π¦
infoβ the MMU mappable range, aka where all the mapping lore lives. πΊοΈiovaβ the virtual address. The β¨imaginaryβ¨ one, iykyk.paddrβ the physical address. The real one, no cap.sizeβ length of the mappable area. Gotta know how much we're working with, fr fr. π
π DESCRIPTION π
So the tea is: this function has been adapted from iommu_map in drivers/iommu/iommu.c. That's literally the whole description, bestie β she's mysterious, she's concise, she's giving main character energy. π
