💖 vmw_cmd_res_switch_backup(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual entry for vmw_cmd_res_switch_backup(9) — yes, that is a whole lot of letters, but we're gonna get through it together 🫶✨

---

✨ NAME ✨

vmw_cmd_res_switch_backup — utility function to handle backup buffer switching 🎀

---

🌸 SYNOPSIS 🌸

int vmw_cmd_res_switch_backup (struct vmw_private *dev_priv , struct
       vmw_sw_context *sw_context , struct vmw_resource *res , uint32_t *buf_id
       , unsigned long backup_offset );

---

🦋 ARGUMENTS 🦋

• dev_priv — pointer to a device private struct 💜
• sw_context — the software context being used for this batch ✨
• res — pointer to the resource 🎀
• buf_id — pointer to the user-space backup buffer handle in the command stream 👑
• backup_offset — offset of backup into MOB 🌈

---

💅 DESCRIPTION 💅

okay so what this function is doing is preparing for registering a switch of backup buffers in the resource metadata, and it does that just prior to unreserving. literally right before, bestie 😭

and yeah, it's basically a wrapper around vmw_cmd_res_switch_backup with a different interface — that's the whole vibe 💫
