STRUCT VMW_CMDBUF_CONTEXT(9)

💖 NAME 💖

okay so bestie, welcome to the struct vmw_cmdbuf_context(9) page from the Kernel API Manual — it's literally all about command buffer context queues ✨. That's the vibe: a struct holding queue lists, a count, and a flag. Periodt.

✨ SYNOPSIS ✨

struct vmw_cmdbuf_context {
    struct list_head submitted;
    struct list_head hw_submitted;
    struct list_head preempted;
    unsigned num_hw_submitted;
    bool block_submission;
};

🎀 Members 🎀

• submitted — a list of command buffers that have been submitted to the manager but are not yet submitted to hardware. lowkey waiting-room energy.
• hw_submitted — a list of command buffers submitted to hardware. they're out there living their truth.
• preempted — a list of preempted command buffers. iconic interruption behavior.
• num_hw_submitted — number of buffers currently being processed by hardware. count 'em.
• block_submission — identifies a block command submission. that's the flag's whole job.
