[gentoo-user] 2.6.35 and AHCI - what about "platform" ?

[Stefan G. Weichinger]

What is a "Platform AHCI Serial ATA controller" ?

Should I set CONFIG_SATA_AHCI_PLATFORM with 2.6.35 now?

I have:

# zgrep -i AHCI /proc/config.gz
CONFIG_SATA_AHCI=y
# CONFIG_SATA_AHCI_PLATFORM is not set

and

# lspci | grep AHCI
00:1f.2 SATA controller: Intel Corporation 82801HB (ICH8) 4 port SATA
AHCI Controller (rev 02)

I am unsure ...

thanks, Stefan

This can be used for AHCI-compatible interfaces implemented inside 
System-On-Chip solutions, or AHCI devices connected via localbus.

I had the exact same question when I was configuring my kernel!

I couldn't tell, I think maybe "Platform" is a brand name? I googled
it and came up with no answers... if you find out the answer, let us
know. :)

Is this as Yes or a No, regarding my Intel SATA chip?

I assume "No" .... ?

Since your SATA controller works without that option enabled, you have a 
normal AHCI controller on your motherboard's southbridge.  That means 
the answer is "no".  You don't need that option enabled.
