Tim, The SATA_mv supported devices stopped at SATA 3Gb and either PCI-e G1 or PCI/PCI-X. The mvSATA supported devices were either SATA 3Gb or SAS/SATA 6Gb. SATA 3Gb devices were PCI-e G1. The newer SAS/SATA 6Gb are PCI-e G2. There are x1, x4, and x8 PCI-e lane widths available. The newer 88SE91xx parts are AHCI compliant, so no need for 3rd party driver. Currently these parts are PCI-e G2 x1. There is a newer version that is sampling that is PCI-e G2 x2. Hope this helps clears this up. -----Original Message----- From: Tim Small [mailto:tim@xxxxxxxxxxx] Sent: Friday, June 10, 2011 11:05 AM To: Mark Lord Cc: Tejun Heo; linux-ide@xxxxxxxxxxxxxxx; Jeff Garzik; Saeed Bishara; Hubert Bailey Subject: Re: Added advisement against marvell ATA controller in the ATA wiki page On 10/06/11 13:19, Mark Lord wrote: > It's only the Marvell AHCI controllers that are causing grief. > The ones supported by sata_mv are among the very best performing SATA > controllers that work with Linux. > It looks to me like Marvell have stopped further development on sata_mv interface cards - does anyone know if it's the case? I couldn't find any SATA3 6GBps, or PCI-e 2.0 chips, so I assumed that Marvell has gone for ahci or mvsas only for it's current/future product ranges? That's why I chose the 88SE9123 - as they seemed to offer reasonable performance/features etc. (albeit single lane PCI express only).
