@@ -119,7 +119,7 @@ One table entry per kernel call, C ABI (System V AMD64), names prefixed
returns are `u64`, errors return as negative values exactly as today.
The calls that return two values in `rax:rdx` today — `dma_alloc`
(virtual_address + physical_address), `msi_bind` (address + data), `shm_create` (virtual_address + handle) —
(virtual_address + physical_address), `msi_bind` (address + data), `shared_memory_create` (virtual_address + handle) —
become functions returning a two-`u64` struct. The System V ABI returns a
16-byte struct in `rax:rdx`, so the stub is a plain `syscall; ret` — the
C-ABI spelling of the existing convention, at zero cost.
