vmw_cmdbuf_set_pool_size(9)

💅 vmw_cmdbuf_set_pool_size(9) 💅

okay bestie, this is the page for vmw_cmdbuf_set_pool_size from the Kernel API Manual — yes, manual name is folded in near the top like a civilized group chat, and no, we are not copying that big header line. 🫶

✨ NAME ✨

vmw_cmdbuf_set_pool_size — Set command buffer manager sizes. That’s literally the name and the whole job, no cap. 💖

🦋 SYNOPSIS 🦋

The signature stays exactly like this, because code is not a vibe we freestyle:

int vmw_cmdbuf_set_pool_size (struct vmw_cmdbuf_man *man , size_t size
);

🎀 ARGUMENTS 🎀

• man — The command buffer manager. That’s the main character of this function. 👑
• size — The size of the main space pool. Big or small, this is the number it gets. 📏

💅 DESCRIPTION 💅

So what this function does is set the size and allocate the main command buffer space pool. Slay. ✨ If it’s successful, that enables large command submissions — highkey iconic. 🔥

Heads up though, bestie: this function requires that rudimentary command submission is already available and that the MOB memory manager is alive. Like, those two things need to be up and running before you come for this function, periodt. 🫶

It returns 0 on success. On failure, it returns a negative error code. 💀
