Subject: [PATCH 2/2] x86: crownbay: Use external graphics card by default
Date: Sat, 31 Jul 2021 21:16:52 +0800	[thread overview]
Message-ID: <20210731131652.19206-2-bmeng.cn@gmail.com> (raw)
In-Reply-To: <20210731131652.19206-1-bmeng.cn@gmail.com>

The board routes the Integrated Graphics Device (IGD) to an LVDS
panel, which is less popular than a PCIe based graphics card.

Disable the IGD so that it does not show up in the PCI configuration
space as a VGA display controller, so we can use an external PCIe
graphics card with whatever cable we have.
