[sata] new libata-dev-2.6 queue created (AHCI, SATA bridges)

Post by Jeff Garzi » Fri, 17 Sep 2004 01:20:12



"libata-dev-2.6" is a new patch queue for SATA features which are under
development, or need additional testing before being deployed into the
upstream-bound libata-2.[46] queues.

It currently contains:

1) A workaround for problems on multiple SATA controllers when using
PATA disks attached via SATA bridges.

2) New driver AHCI. This should currently be considered a technology
preview or early beta test. Simply because it is a young driver on
complicated hardware, using a new "FIS-based" delivery method (read:
brand new hotpath), caution is advised. Do not use in production yet.


I have updated my SATA status page to reflect these updates:

[PATCH] libata basic detection and errata for PATA->SATA bridges

This patch works around an issue with WD drives (and possibly others) over SiL PATA->SATA Bridges on SATA controllers locking up with transfers > 200 sectors.

Good stuff :-)

Is there any news on Marvell progress? I'll get my hands dirty on a
shipment with servers using the chips on friday, I may be able to sneak
in some testing before deployment (they will be rewired to use ICH5-R
for now)

Hmm, I wonder if there is any AHCI PCI(-X/E) plug-in boards planned.
That would be nice indeed. Seems like SATAII-like features on PCI-boards
are bound to Marvell or hardware RAID cards like 3ware 9xxx or newer LSI
MegaRAID currently.
