STRUCT AMDGPU_MUX_ENTRY(9)

✨ NAME ✨

struct amdgpu_mux_entry — the entry recording software rings copying information. that's literally the whole point, bestie. 💅 this page is from the Kernel API Manual, and the title is struct amdgpu_mux_entry(9) — iconic, no cap.

🌸 SYNOPSIS 🌸

       struct amdgpu_mux_entry {
           struct amdgpu_ring      *ring;
           u64 start_ptr_in_hw_ring;
           u64 end_ptr_in_hw_ring;
           u64 sw_cptr;
           u64 sw_rptr;
           u64 sw_wptr;
           struct list_head        list;
        };

🎀 Members 🎀

okay so here's the full field lineup — every single member, zero skipped:

• ring — the pointer to the software ring. it's giving main character pointer energy. 🦋
• start_ptr_in_hw_ring — last start location copied to in the hardware ring.
• end_ptr_in_hw_ring — last end location copied to in the hardware ring.
• sw_cptr — the position of the copy pointer in the sw ring.
• sw_rptr — the read pointer in software ring.
• sw_wptr — the write pointer in software ring.
• list — list head for amdgpu_mux_chunk.
