A UEFI DXE driver (built with edk2) that enables Resizable BAR on motherboards that lack official support, injected into the firmware's DXE volume. It ships with a ReBarState utility to configure the BAR size after the patched firmware is installed.
Use cases
- enable resizable BAR on an unsupported motherboard
- make an Intel Arc GPU work optimally
- patch UEFI firmware to add ReBAR support
- increase GPU performance via large PCIe BAR
- set Resizable BAR size from Linux or Windows
When to choose
- your motherboard BIOS has no Resizable BAR option
- you need ReBAR for Intel Arc GPUs
- you are comfortable modifying your UEFI firmware image
When to avoid
- you are not comfortable flashing modified firmware (risk of bricking)
- your system requires Secure Boot with only signed modules
- you only want a simple BIOS toggle rather than firmware patching
