amdgpu_vm_bo_base_init(9)
π amdgpu_vm_bo_base_init β the Kernel API Manual, but make it make sense
okay so bestie, this is a page from the Kernel API Manual, section 9, and the star of the show is amdgpu_vm_bo_base_init. No cap, it's a small function but it does a very real job, so let's get into it π«Ά
β¨ NAME β¨
amdgpu_vm_bo_base_init β Adds bo to the list of bos associated with the vm π
πΈ SYNOPSIS πΈ
void amdgpu_vm_bo_base_init (struct amdgpu_vm_bo_base *base , struct
amdgpu_vm *vm , struct amdgpu_bo *bo );
Literally just three pointers and a dream, iykyk π
π¦ ARGUMENTS π¦
baseβ the base structure for tracking BO usage in a VM. She's the record-keeper, the main character of the bookkeeping πvmβ the vm to which bo is to be added. Like, the whole address-space situation the bo is moving into πboβ an amdgpu buffer object. The bo in question. The icon itself π
π DESCRIPTION π
So what does it actually do? It initializes a bo_va_base structure and adds it to the appropriate lists. That's the whole vibe β set the thing up, then slot it into the right list(s) so the VM knows this bo exists. Periodt. β¨
π SEE ALSO π
This is the part where the manpage goes absolutely feral with cross-references, and honestly? Respect. Every single one, in order, no skips π₯
