AFAIK, the readahead setting is a kernel-default thingie - nothing to fiddle with. And nothing that is dependent on harddisk hardware (instead of multicount).

[gentoo-user] Need help to improve boot time using readahead-list
Hi, I'm trying to use readahead-list to improve my system's boot time. But I'm now stuck in customizing /etc/readahead-list to fit my system. So if anyone used it, could you give me some advices? Thanks. P/s: I read about this<http://www.gentoo-wiki.info/HOWTO_prefetch_files_on_boot>but it doesn't seem to help improving boot time much. -- Nguyễn Bảo Ngọc http://www.facebook.com/pymaster

This is mostly because hdparm makes sure that it is reading from the disk, not the kernel buffers (disk buffers are OK, which is why it says "buffered reads"). But there is always: # time dd if=/dev/hda bs=64k count=16000 (time the reading of 1G of data from hda). Feel free to adjust count to your liking...although it should be at least twice memory.

Re: [gentoo-user] setting "using_dma" on a BenQ DVD/RW drive
I'm starting to believe that it has something to do with some option in the kernel that is not enabled. I just swap the CD/RW Plextor from the machine that is working OK on kernel 2.6.11 (where DMA is enabled and everything is working, CD/RW, except eject - but that is another story) into a new New Machine on kernel-2.6.12 Anyhow, I just put the Plextor CD/RW into my new machine and the DMA was not not enabled: hdparm /dev/hdc for plextor on working machine. /dev/hdc: IO_support = 1 (32-bit) unmaskirq= 1 (on) using_dma= 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead= 256 (on) hdparm for plextor on new machine: /dev/hdd: IO_support = 0 (16-bit) unmaskirq= 0 (off) using_dma= 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead= 256 (on) So, I strongly believe it has to do with some setting in the kernel or diver. Another interesting thing is that lshw is not even listing CDROM present in a new machine for both drives: BenQ and Plextor, even though kernel detects them correctly. I did not put BenQ Writer into working machine, I'll try to analyze both kernel settings first, to see what I'm missing. -- #Joseph > > This makes it more likely that the problem is lack of support for your > > IDE chipset in your kernel. > > Joseph, > > Please post *ALL* of the output of a dmesg and lspci-v command. > I too believe chipset issues are most likely the problem. > > I am at present fighting a similar problem with a 915GM. > > -- > Regards, > Ray > > > -- gentoo-user@gentoo.org mailing list

Yea, I've seen/used this syntax/test before, but, I'm not too sure
how robust it is.
Here's my results after a reboot:
/dev/hda:
multcount= 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq= 0 (off)
using_dma= 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead= 256 (on)
geometry = 16383/255/63, sectors = 60011642880, start = 0
icelander:/home/james# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1860 MB in 2.00 seconds = 930.14 MB/sec
Timing buffered disk reads: 116 MB in 3.02 seconds = 38.35 MB/sec
NOW:
icelander:/home/james# hdparm -d 1 -A 1 -m 16 -u 1 -c1 -a 256 /dev/hda
/dev/hda:
multcount= 16 (on)
IO_support = 1 (32-bit)
unmaskirq= 1 (on)
using_dma= 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead= 256 (on)
geometry = 16383/255/63, sectors = 60011642880, start = 0
icelander:/home/james# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1860 MB in 2.00 seconds = 929.68 MB/sec
Timing buffered disk reads: 116 MB in 3.03 seconds = 38.30 MB/sec
Hard to believe that 32bit mode, and the other settings make no difference
in performance.
hdparm -i /dev/hda shows:
Model=HTS726060M9AT00, FwRev=MH4OA68A, SerialNo=MRH403M4GLMLKB

AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: ATA/ATAPI-6 T13 1410D revision 3a:
Which *udma5 selected may not need these other settings.
I'm just not sure why
hdparm -k1 /dev/hda
does not permanently save settings, after a reboot. Googling
does not produce anything useful. Surely I do not have to embedded
these hdparm settings to get activated upon reboot?
Surely we have a HD(hdparm) expert somewhere in the Gentoo community?

It only works across drive resets, and it is something you SHALL NOT use. Because if your drive resets, it has usually some problems, forcing DMA over a flaky cable could kill your data in that moment. If the problems disappeared, you can always issue hdpam -d1 again ... I guess, you have not read man hdparm: -A Disable/enable the IDE drive's read-lookahead feature (usually ON by default). -k Get/set the keep_settings_over_reset flag for the drive. When this flag is set, the driver will preserve the -dmu options over a soft reset, (as done during the error recovery sequence). This flag defaults to off, to prevent drive reset loops which could be caused by combinations of -dmu settings. The -k flag should therefore only be set after one has achieved con- fidence in correct system operation with a chosen set of configuration settings. In practice, all that is typically neces- sary to test a configuration (prior to using -k) is to verify that the drive can be read/written, and that no error logs (kernel messages) are generated in the process (look in /var/adm/messages on most systems). -K Set the drive's keep_features_over_reset flag. Setting this enables the drive to retain the settings for -APSWXZ over a soft reset (as done during the error recovery sequence). Not all drives support this feature. and there is a lot more interesting stuff in it. Glück Auf Volker -- gentoo-user@gentoo.org mailing list

[gentoo-user] Faulty IDE ribbon?
Hi All,
Just checking before I buy a new ribbon, that there is nothing more sinister
happening with my secondary IDE controller. Suddenly and with no activity
on my secondary IDE controller there's a noise as if my /dev/hdc (8G ATA
drive) and /dev/hdd (CDWR) are reinitialised - i.e. the mechanical noises
usually observed when the machine is switched on and the BIOS probes the
devices on booting.
Both devices are not mounted and there is no media in the CDWR. This is
what dmesg shows:

I've just tried Knoppix 3.8.1 which comes with Linux kernel 2.6.11, and surprise, when tweaking the hd params with the same values (except geometry) as before /dev/hda: multcount= 16 (on) IO_support = 1 (32-bit) unmaskirq= 1 (on) using_dma= 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead= 8 (on) geometry = 65535/16/63, sectors = 78198750, start = 0 the buffered read performance is 17,44 MB/sec as with Gentoo.

Both should give you a little bit of speedup. With hdparm -iI /dev/hda you can check which (u)dma mode is used by your drive. -- gentoo-user@gentoo.org mailing list

If the init-script needs to run after a specific (set of) other init-script(s)
and/or before a specific (set of) other init-script(s), you can add these to
to the "before" and "after" lists respectively.
As example, the following is copied from the /etc/init.d/xdm file:
---
depend() {
need localmount
# this should start as early as possible
# we can't do 'before *' as that breaks it
# (#139824) Start after ypbind and autofs for network authentication
# (#145219) Could use lirc mouse as input device
# (#70689 comment #92) Start after consolefont to avoid display
corruption
after bootmisc readahead-list ypbind autofs openvpn gpm netmount lircd
consolefont
before alsasound
# Start before X
use acpid consolekit hald xfs
}
---
This will allow you to disable init-scripts that you no longer need, without
having your init-script becoming disabled.
HTH.

Try it with unmaskirq both ways, etc. Do a reboot also and make sure your settings stick. They probably will but it's good to do a check while you're looking at this vs. tomorrow when you're not.

Re: [gentoo-user] Knoppix twice as fast as Gentoo?
In the Gentoo manual, in the early stages, it mentions -tT; nearby &
below, it mentions another hdparm line to speed things up. Did you try
that line?
(At least, the version of the book on the 2004.3 universal CD had such
a line.)

depscan.sh didn't help.
I find that when I remove xdm from default runlevel
everything works fine.
I can also see that when stopping xdm via:
/etc/init.d/xdm stop
I receive error message.
My xdm depend() section looks like:

Do You have any idea what can be wrong ?

It's pretty hard to believe that the video hardware is the problem. I've played back DVDs on laptop ATI chipsets a decade older than yours and it worked fine. I've currently got a two year old ATI laptop chipset (X300?), and it has no trouble playing DVDs using either the Radeon or the fglrx drive. My guess is the optical drive doesn't have DMA enabled. DMA is enabled. If it were not, I would also expect to see the choppiness no matter what the video size. tagalong conf.d # hdparm /dev/hdb /dev/hdb: IO_support= 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) You may want to check to make sure the XV video overlay support is enabled, but even without it, playing back SD video purely in software shouldn't be a problem on anything with a CPU faster than 500MHz. How can I verify XV video overlay support? I'm sure my CPU is capable as its an AMD Turion dual core running at 1.6ghz. Thanks, Drew -- Be a Great Magician!

I am also waiting for kernel 2.6.20 as it has a setting for the core 2 duo in processor settings. Maybe i try the testing version of it. Also the new gcc compilers will support the core 2 duo directly, but i think it will take some time till 4.2 or even 4.3 will become stable.

Hi, Now that eselect-sh has been stabilized, I'm wondering if anyone has tried setting dash as the /bin/sh symlink. Any experiences? I've been using dash as my /bin/sh for a while now. I've had it installed since June 2009, I suppose I've had the symlink set for the same length of time. Pretty much all incompatibilities I encountered are fixed now, stuff like openrc introducing bashisms (what fun! I never used the debug option of an init script before or since), or the Audacity build system having #!/bin/sh but using bashisms. I seem to recall that I have one package installed that has this problem and requires changing the symlink temporarily, but I don't remember which. It might have been fixed by now, though. Also, the old mysql-init-scripts-1.2 package requires bash, in case that matters to you. The dmcrypt init script also has a single bashism. A bug about this has been open for quiet some time now: https://bugs.gentoo.org/show_bug.cgi?id=408117 So I don't think you should expect any problems (save for the rare exception), and for me there was a noticeable speedup with the init system (also reported by Flameeyes in his blog).

I think it is more useful on desktops and laptops, which get rebooted regularly. On a server that tends to run for months without a reboot, a fast init-system is important.

[gentoo-user] Problem with hdparm and SATA-controller
Hi,
I want to optimize the "sound output" of my shiny new sata disc, but I
have some problems to set hdparm options. My options look like this:
# SATA Disk
sda_args="-d1 -c1 -u1 -A1 -S6 -M128 -B1"
I don't know, if I really want it to spin down, since my system is
running on it. But that's not the real problem. I think I have a problem
with my sata driver, since the output of hdparm looks like this:
hive linux # hdparm /dev/sda
/dev/sda:
IO_support= 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 30394/255/63, sectors = 488281250, start = 0

This was AFTER starting hdparm with the options given above. I also have
