Subject: [PATCH 06/17] video: Allow syncing the entire framebuffer to the copy
Date: Wed, 13 Jan 2021 20:29:46 -0700	[thread overview]
Message-ID: <20210114032957.483086-7-sjg@chromium.org> (raw)
In-Reply-To: <20210114032957.483086-1-sjg@chromium.org>

In some cases so much of the framebuffer is updated that it is not worth
copying the changes piece by piece to the copy framebuffer. Add a function
to copy the whole thing.
