vmw_execbuf_submit_cmdbuf(9)

okay bestie, welcome to vmw_execbuf_submit_cmdbuf(9) in the Kernel API Manual — this is the page about patching a command batch and submitting it through the command buffer manager ✨. No cap, it's a little niche, but we're gonna make it make sense 🫶.

💖 NAME 💖

vmw_execbuf_submit_cmdbuf — patches up a command batch, then submits that batch through the command buffer manager. That's the whole main-character job 💅.

✨ SYNOPSIS ✨

int vmw_execbuf_submit_cmdbuf (struct vmw_private *dev_priv , struct
       vmw_cmdbuf_header *header , u32 command_size , struct vmw_sw_context
       *sw_context );

🎀 ARGUMENTS 🎀

• dev_priv — a pointer to the device private structure. It's giving "device's own little info hub" energy 🏠.
• header — the opaque handle to the command buffer allocation. Opaque means we don't stare directly at its internals, bestie — we just pass the handle along 🙈.
• command_size — the size of the unpatched command batch. Pre-patch size, for the record 📏.
• sw_context — the structure that holds the relocation lists. It's carrying the relocation-list cargo 🎀.

🦋 DESCRIPTION 🦋

Real talk: this function has side effects. If it returns 0, then the command buffer represented by header will have been modified. That's the vibe check: 0 means the header-represented command buffer got changed 💅.
