Subject: [patch 0/2] fastboot: allow skipping probing of known-unused ports in libata
Date: Mon, 11 Aug 2008 15:35:42 -0700 [thread overview]
Message-ID: <20080811153542.61095e5c@infradead.org> (raw)
Hi,
if you KNOW a certain ata port is not connected (for example in a
netbook where there's just nothing there possible), we still probe
the port currently and waste time. This time is a significant part of
the total boot time.
This patch series introduces a module parameter that can be used
to tell the kernel which ports to skip, and the second patch
adds a DMI list for known setups so that for known cases
users don't have to add any parameters at all.
