From 7575cc5396f398d408f30dd9f9797e045f81c480 Mon Sep 17 00:00:00 2001 From: mav Date: Tue, 26 Jan 2010 15:25:24 +0000 Subject: [PATCH] Add support for SATA part of Marvell 88SE912x controllers to ahci(4). Limit early revisions from 6Gb/s to 3Gb/s by default, or they negotiate only 1.5Gbps, when 3Gb/s devices connected. Add dummy driver for PATA part of these controllers, preventing generic driver attach them. It causes system freeze when SATA controller used after PATA was touched. --- sys/dev/ahci/ahci.c | 273 +++++++++++++++-------------- sys/dev/ata/ata-pci.c | 1 + sys/dev/ata/ata-pci.h | 1 +
