Subject: [PATCH 1/4] OvmfPkg/Bhyve: enable bus enumeration
Date: Mon, 14 Jun 2021 11:00:57 +0200	[thread overview]
Message-ID: <20210614090100.7763-2-c.koehne@beckhoff.com> (raw)
In-Reply-To: <20210614090100.7763-1-c.koehne@beckhoff.com>

Neccessary for GPU Passthrough of dedicated AMD GPUs. For Linux
guests, AMD GPUs require that their PCI ROM is processed by UEFI.
Enable bus enumeration to process the PCI ROM of all devices.
