πŸ’… amdgpu_bo_fa...serve_notify(9) πŸ’…

okay so bestie, welcome to the Kernel API Manual β€” yes the truncated name is literally how it's printed, don't come for me, that's just how the header line does it. this page is about amdgpu_bo_fault_reserve_notify and it's shorter than my attention span so let's GO ✨


🌸 NAME 🌸

amdgpu_bo_fault_reserve_notify β€” notification about a memory fault 🫢


✨ SYNOPSIS ✨

vm_fault_t amdgpu_bo_fault_reserve_notify (struct ttm_buffer_object *bo
);

πŸŽ€ ARGUMENTS πŸŽ€

  • bo β€” pointer to a buffer object. that's it. that's the whole argument. she's lowkey simple like that πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so what this one does: it notifies the driver that we're taking a fault on this BO and that we have reserved it β€” and while it's at it, it also performs bookkeeping (yes, the boring admin work, somebody has to do it πŸ™ˆ).

also important, no cap: this is the TTM driver callback for dealing with vm faults. that's its whole job. main character energy in the vm fault department fr fr πŸ‘‘


πŸ’– RETURN πŸ’–

0 for success, or a negative error code on failure. iconic either way, but like... we prefer the 0 😭
