# BAR Emulation Specification (GSP 570.144W)
+> **Historical document — superseded.** The `BAR_TRAP` RPC (type 0x0A)
+> described here is **not used**: in emulation mode it returns `-ENOTSUPP`,
+> and BAR access is synchronous MMIO through the BAR shadow. Guest-visible BAR
+> windows are BAR0 (16 MB register MMIO), BAR1 (256 MB VRAM aperture) and
+> BAR3 (instance window). Canonical documentation:

## Overview
-The GSP firmware implements BAR (Base Address Register) emulation for virtual GPU (vGPU) through the **BAR_TRAP** RPC (type 0x0A). The main handler at **0x04CB8188** (40 KB) manages BAR1 aperture, forced access, and memory backing.

The main handler at **0x04CB8188** (40 KB) manages BAR1 aperture, forced access, and memory backing. **This RPC is not used by the live path**: in emulation mode `BAR_TRAP` returns `-ENOTSUPP`; guest BAR access is handled synchronously as MMIO through the BAR shadow (`../kernel/bar_emulation.c`), not via an RPC.

## Overview
Open-IOV includes **emulation mode** that allows operation with unmodified consumer/OpenRM GSP firmware by emulating missing vGPU RPC handlers locally in kernel and userspace.
