New Revision: 191568
URL: http://svn.freebsd.org/changeset/base/191568
Log:
- Always force AHCI mode on a ATI/AMD SB600/700/800 SATA
controller. These controllers may be configured as legacy IDE
mode by modifying subclass and progif without actually changing
PCI device IDs. Instead of complicating code, we always force
AHCI mode while probing. Also we restore AHCI mode while
resuming per ATI/AMD register programming/requirement guides. -
Fix SB700/800 "combined" mode. Unlike SB600, this PATA
controller can combine two SATA ports and emulate one PATA
channel as primary or secondary depending on BIOS configuration.
When the combined mode is disabled, this channel disappears and
it works just like SB600 PATA controller, however. - Add more PCI
device IDs for SB700/800 and adjust device descriptions. SB800
shares the same PCI device IDs and added two more SATA IDs.
Thanks.
Thank you for answering my stupid questions!
BTW, ATI SATA phy reset/resume requires slightly different sequence
from generic AHCI one but it just works (with little annoying timeout
message). :-)
If you are talking about port 15 soft-reset timeout when port multiplier
is absent, then this is known ATI controllers bug/feature. I have even
added some comments in ata-ahci.c about it, but as soon as it is
nonstandard and I have no respective hardware, I have left it for later.
