Subject: [PATCH v2 02/28] x86: qemu: Switch to bochs display
Date: Sun, 16 Feb 2025 13:43:47 -0700	[thread overview]
Message-ID: <20250216204421.3560012-3-sjg@chromium.org> (raw)
In-Reply-To: <20250216204421.3560012-1-sjg@chromium.org>

The vesa display is widely used on hardware, but it is a bit of a pain
with QEMU. It requires executing option ROMs, which either doesn't work
with kvm, or is difficult to do in a kvm/QEMU-friendly way.

THe bochs display is probably better anyway, so switch to that. It works
fine with kvm as it doesn't need an option ROM.
