Thank you for posting on the Intel️® communities. We understand that you are looking for information about Resizable BAR support.
You should consider that Resizable BAR (Base Address Register) is a PCIe capability. This is a mechanism that allows the PCIe device, such as a discrete graphics card, to negotiate the BAR size to optimize system resources. Enabling this functionality can result in performance improvement. This feature is enabled in the system firmware (BIOS) settings to enable it.
For more information, or to check if your system supports resizable BAR, contact the system or motherboard manufacturer for support.
