| |
"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: http://linux.yyz.us/sata/sata-status.html
BK users: bk pull bk://gkernel.bkbits.net/libata-dev-2.6
