FreeBSD 8.0-BETA2 camcontrol device openings - have tagged queuing?
Phillip Musumeci
Hi,
There was a "HEADS UP: Major CAM performance regression" (see
http://lists.freebsd.org/pipermail/freebsd-stable/2009-February/048366.html)
in Feb09 about a possible reduced performance on some disk subsystems,
in particular systems where camcontrol reports "device openings: 1".
Further posts indicated that the problem did not exist in FreeBSD 6.4.
My setup:
1) FreeBSD 8.0-BETA2 (boot dmesg is attached below)
2) two Samsung 400GB AL-HD400LJ disks in a USB/firewire2 enclosure using
an Oxford 924DSB chipset (see
http://zytech.com.au/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ENXP800S
where I understand that the HD400LJ disks with their SATA-3Gbps
interface also have Native Command Queuing as found in newer SATA2)
3) the USB connected disk enclosure is attached to ehci0 which is a <VIA
VT6202 USB 2.0 controller> as reported in dmesg below.
My question: my disks report "device openings: 1". Can I do anything to
get these disks to use tagged queuing? Here is some status info.
$ camcontrol tags da0
(pass0:umass-sim0:0:0:0): device openings: 1
$ camcontrol tags da1
(pass1:umass-sim0:0:0:1): device openings: 1
Note that the more detailed tags information shows mintags==2 and
maxtags==255, as in
$ camcontrol tags da0 -v
(pass0:umass-sim0:0:0:0): dev_openings 1
(pass0:umass-sim0:0:0:0): dev_active 0
(pass0:umass-sim0:0:0:0): devq_openings 1
(pass0:umass-sim0:0:0:0): devq_queued 0
(pass0:umass-sim0:0:0:0): held 0
(pass0:umass-sim0:0:0:0): mintags 2
(pass0:umass-sim0:0:0:0): maxtags 255
$ camcontrol tags da1 -v
(pass1:umass-sim0:0:0:1): dev_openings 1
(pass1:umass-sim0:0:0:1): dev_active 0
(pass1:umass-sim0:0:0:1): devq_openings 1
(pass1:umass-sim0:0:0:1): devq_queued 0
(pass1:umass-sim0:0:0:1): held 0
(pass1:umass-sim0:0:0:1): mintags 2
(pass1:umass-sim0:0:0:1): maxtags 255
Thanks,
phillip

Hi,
SYSTEM is: FreeBSD 9.0-CURRENT system csup-ed and rebuilt Friday Sep 25
2009 (problem also noticed in 8-BETA2); ports csup-ed same day.
PROBLEM: a rebuild of libX11-1.2.1_1,1 is broken by macro definitions
provided in files belonging to smpeg-0.4.4_8 (one such file is
/usr/local/share/aclocal/smpeg.m4). Below is a fragment of the messages
before failing with an update via portmaster.
FIXED elsewhere??? The google search
http://www.google.com/search?hl=en&q=fixed+underquoted+definition+of+AM_PATH_SMPEG
suggests that this was fixed in smpeg-0.4.5 but our ports system seems
to only have a version 0.4.4. As I can download a prebuilt
libX11-1.2.1, how are people working around this (or is there an
alternative macro set)?
Thanks,
phillip
