💖 vmw_cmdbuf_idle(9) — Kernel API Manual 💖

okay so bestie, welcome to the vmw_cmdbuf_idle(9) glow-up from the Kernel API Manual ✨ this page is short, iconic, and fully loaded with the exact deets. no cap 🫶

🌸 NAME 🌸

vmw_cmdbuf_idle — Wait for command buffer manager idle. That's the whole name section, and honestly it ate 💅

✨ SYNOPSIS ✨

int vmw_cmdbuf_idle (struct vmw_cmdbuf_man *man , bool interruptible ,
       unsigned long timeout );

🎀 ARGUMENTS 🎀

• man — The command buffer manager. This is the main character we're waiting on 👑
• interruptible — Sleep interruptible while waiting. Yes bestie, that's the vibe 🌙
• timeout — Time out after this many ticks. Clock is ticking, fr fr ⏳

🦋 DESCRIPTION 🦋

Here's the tea: vmw_cmdbuf_idle waits until the command buffer manager has processed all command buffers, or until a timeout occurs. If a timeout occurs, the function will return -EBUSY. That's the plot twist, and it is literally right there 😭🔥
