From 517d3cc15b36392e518abab6bacbb72089658313 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Wed, 13 May 2009 15:02:42 +0100 Subject: [PATCH] [libata] ata_piix: Enable parallel scan This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team.
