Subject: AHCI should try to claim all AHCI controllers
Date: Tue, 31 Oct 2006 23:06:32 +0800 [thread overview]
Message-ID: <FFECF24D2A7F6D418B9511AF6F358602F2CE9E@shacnexch2.atitech.com> (raw)
Hi all,
According to PCI 3.0 spec, ACHI's PCI class code is 0x010601,
and I suggest the ahci driver had better try to claim all ahci
controllers, pls see the following patch:
diff -Nur linux-2.6.17/drivers/scsi/ahci.c
