Please see below for a description of my problem, which I had written
about to SuperMicro support. Further to what I've written there, I
have modified the ahci driver source to force HOST_CAP_PMP as in the
diff included below. Now when this modified driver is loaded, it does
attempt PMP, and it appears to be working except the all but the first
drive attached to the port multiplier are not recognized. I've included
relevant syslog entries below.
Any advice as to what I can try next?
Thanks,
Todd

You need to ask the chassis/backplane manufacturer which controller
is compatible with the Silicon Image SiI3726 chip.
For example, Super Micro also has some LSI chip expander chassis/backplane.
Only some controllers are compatible.

Subject: X8DTL-6F motherboard, Intel ICH10 SATA, and port multiplier
Dear SuperMicro Support,
I have a SuperMicro X8DTL-6F motherboard and I'm trying to use the onboard
Intel ICH10 SATA ports attached to a SATA port multiplier.
The SATA port multipliers are based on the Silicon Image SiI3726 chip and
have five SATA drive ports.
In the motherboard BIOS settings, I've configured SATA as AHCI.
When booting the system, the BIOS only sees the first drive on the port
multiplier. Also, if I have fewer than five drives attached to the port
multiplier, the boot hangs during drive detection and never completes.
Next I boot linux, and linux also sees only the first drive on the
five-drive port multiplier. Here are some details seen from linux:
- linux kernel version 2.6.31
- output from lspci
00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA
AHCI Controller
- from /var/log/syslog
Feb 18 20:24:39 rhpcbkup klogd: ahci 0000:00:1f.2: AHCI 0001.0200 32 slots
6 ports 3 Gbps 0x3f impl SATA mode
Feb 18 20:24:39 rhpcbkup klogd: ahci 0000:00:1f.2: flags: 64bit ncq sntf
stag pm led clo pio slum part ems
Feb 18 20:24:39 rhpcbkup klogd: ahci 0000:00:1f.2: setting latency timer
to 64
The second syslog line above that shows "flags" that, if I understand
correctly, are discovered by the linux ahci driver when it probes the
BIOS. There should be a "pmp" flag shown above if the ahci driver
detects that the SATA controller has port multiplier support using either
command-based or FIS-based SATA PM switching.
I've read that this Intel ICH10 SATA controller should have SATA PM
support. So what I'm wondering is whether this should be available
on this particular SuperMicro motherboard, and whether there's anything
I can do to make this work from the BIOS and linux.
Thanks,
