[gentoo-user] Custom Timer Frequency (CONFIG_HZ)?

2011-08-11 Thread Pandu Poluan
Just wondering, is it possible to specify a custom timer frequency?
E.g., HZ=500 instead of one of the canned values (100, 250, 300,
1000).

It is possible, but it's a bad idea because non-standard values can 
result in driver breakage.  Some code assumes specific timer 
granularities (100Hz = 10ms, 250Hz = 4ms, etc).  This usually happens 
with values above 1000Hz, so it might be possible to experiment with 
non-standard sub-1000Hz values.


But why do you want a custom value anyway?

Well, for a firewall, I've calculated (gathered and extrapolated from
a lot of sources), the latency per-packet is usually less than 1 ms,
at worst still less than 2 ms.

Thus, setting the timer freq to 100 Hz (as suggested for 'normal'
server load) means the timeslice is way too long (10 ms per time
slice).

So, I speculate that better -- and uniform -- performance will be
achieved with a timer freq of 500 Hz.

Of course, this is a wild speculation/guess from me. I never quite
understand netfilter/xtables' relation to the timeslices, so I may be
talking nonsense :-)

Thanks for the explanation, Nikos. Since the size difference is very

This assumes that networking is dependent on the timer interrupt, which 
doesn't seem to be the case; going from 100Hz to 1000Hz will not result 
in network latencies dropping by 9ms.  I know because I tried it on a 
server.


The only case where network latency improved with a higher HZ was with a 
game server (Counter-Strike) and that's only because that game's server 
component is timer dependent when calculating the game world (to do 1000 
updates per second it needs a HZ value of 1000).  So that application 
has some real-time demands, meaning a high HZ value helps.  Otherwise, 
you can stick to 100Hz on a server.  Higher values won't change anything 
and will only reduce throughput (though not by much anyway, which is why 
some people set 1000Hz even on servers.)

  No, this is plain wrong. Redefinition of a struct is an error in C and

 Hm.  I know I've seen compiler redefinition messages thousands of times
 over the years.  Is it really possible that all of those thousands were
 errors instead of warnings?  If that's true then I've wasted a lot more
 time tracking them down than I care to think about :)

struct redefinition is always an error.
Maybe what you saw as a warning was some kind of macro redefined.

~ $ cat bar.c
#define BAR 0
#define BAR 1

int main()
{
}

~$gcc bar.c -o bar
bar.c:2:0: warning: BAR redefined
bar.c:1:0: note: this is the location of the previous definition

Note the different wording in the message.

I think, aconnect (part of media-sound/alsa-utils) is the tool you want to

Start both rosegarden and zynaddsubfx, then use aconnect -lio to see, what in-

the rosegarden out-port with the zynaddsubfx in-port.

Looks like rosegarden cannot work with pure alsa. I did not know this.
There's seq24 in portage, which seems to be a step sequencer that works 
without jack. You could try this one instead of rosegarden. I don't know 
anything about it though.

 How can I prevent to scratch my skin by the roses of this garden over

We could try to solve your problems with jack :)
I recommend qjackctl for jack-server handling.
How do you start it? What use-flags are set for it?
Another option is to try the versions from the pro-audio overlay (that's what 
I use for rosegarden, jack, ardour and some other audio related stuff).
Did you try other synths with jack and rosegarden? Maybe there's a bug in 
zynaddsubfx. You could try eg hydrogen to test this.

 Hi Michael,

 What do I need for a midi connection (sorry, I am

do you have midi-ports in your soundcard? In some cases they are
implemented as 5-pol Din plugs (MIDI-standard plugs), in other
cases
they are implemented via the gameport. Most built-in
soundhardware has none.
If you have those ports, the most simple (but not best) solution
is to connect midi in with midi out, have rosegarden play
through midi out and the synth listen to midi in.
Afaik(!) alsa has virtual midi-ports, you can use, if you have

Hi Michael,

 I will try (again) to be a friend of Jack (NOT Daniels ;) )...

 What I dont understand: Why all this hassle with Jack if Rosegarden
 has the ability to connect directly to Zynaddsubfx without any
 other gadget (see Studio-Manage Midi Devices, start Zynaddsubfx
 first)??? And if instructed so, why does this dialog still pops
 up and reminds me of a non existing Jack connection?

 I tried the masked version 11.06 of rosegarden: The same effect.

 I removed the jack USE-Flag from make.conf temporarily and
 rebuild rosegarden: No change.

 Ok, I will try jack...again...sigh.

  Hi Michael,
  
  Thank you for your help ! :)
  
  Here are the versions:
  media-sound/rosegarden 11.02
  media-sound/zynaddsubfx 2.4.1
  media-sound/jack-audio-connection-kit 0.118.0
 
 looks ok to me. No idea, why it doesn't work for you.
 
  I did a aconnect -lio, which says:
  
  client 0: 'System' [type=kernel]
  0 'Timer   '
  1 'Announce'
  Connecting To: 15:0, 128:0
  client 14: 'Midi Through' [type=kernel]
  0 'Midi Through Port-0'
  client 28: 'Virtual Raw MIDI 3-0' [type=kernel]
  0 'VirMIDI 3-0 '
  Connecting To: 128:0
  Connected From: 128:3
  client 29: 'Virtual Raw MIDI 3-1' [type=kernel]
  0 'VirMIDI 3-1 '
  client 30: 'Virtual Raw MIDI 3-2' [type=kernel]

  Connected From: 0:1, 28:0
  1 'sync out'
  2 'external controller'
  3 'out 1 - General MIDI Device'
  Connecting To: 28:0
  
  
  Then I started rosegarden, which - as expereinced before - pops up
  a dialog, saying:
  
  The JACK Audio subsystem has stopped Rosegarden from processing audio,
  probably because of a processing overload.  An attempt to restart the
  audio service has been made, but some problems may remain.  Quitting
  other running applications may improve Rosegarden's performance.
  
  (no jackd was running)
  
  When clicking [OK] the dialog disappears only to take a very very short
  rest an return again and again and again
  
  In one of these short tiemes of peace and slumber I open the
  preference dialog and switched off jackd transport, quit rosegarden
  and start it again only to play another fresh match between me and
  this damned dialog... ;-/
 
 Looks like rosegarden cannot work with pure alsa. I did not know this.
 There's seq24 in portage, which seems to be a step sequencer that works 
 without jack. You could try this one instead of rosegarden. I don't know 
 anything about it though.
 
  How can I prevent to scratch my skin by the roses of this garden over
  and over again.?
 
 We could try to solve your problems with jack :)
 I recommend qjackctl for jack-server handling.
 How do you start it? What use-flags are set for it?
 Another option is to try the versions from the pro-audio overlay (that's what 
 I use for rosegarden, jack, ardour and some other audio related stuff).
 Did you try other synths with jack and rosegarden? Maybe there's a bug in 
 zynaddsubfx. You could try eg hydrogen to test this.

 Just wondering, is it possible to specify a custom timer frequency?
 E.g., HZ=500 instead of one of the canned values (100, 250, 300,
 1000).

 It is possible, but it's a bad idea because non-standard values can
 result
 in driver breakage.  Some code assumes specific timer granularities
 (100Hz =
 10ms, 250Hz = 4ms, etc).  This usually happens with values above 1000Hz,
 so
 it might be possible to experiment with non-standard sub-1000Hz values.

 But why do you want a custom value anyway?


 Well, for a firewall, I've calculated (gathered and extrapolated from
 a lot of sources), the latency per-packet is usually less than 1 ms,
 at worst still less than 2 ms.

 Thus, setting the timer freq to 100 Hz (as suggested for 'normal'
 server load) means the timeslice is way too long (10 ms per time
 slice).

 So, I speculate that better -- and uniform -- performance will be
 achieved with a timer freq of 500 Hz.

 Of course, this is a wild speculation/guess from me. I never quite
 understand netfilter/xtables' relation to the timeslices, so I may be
 talking nonsense :-)

 This assumes that networking is dependent on the timer interrupt, which
 doesn't seem to be the case; going from 100Hz to 1000Hz will not result in
 network latencies dropping by 9ms.  I know because I tried it on a server.


That's what I was concerned of.

 The only case where network latency improved with a higher HZ was with a
 game server (Counter-Strike) and that's only because that game's server
 component is timer dependent when calculating the game world (to do 1000
 updates per second it needs a HZ value of 1000).  So that application has
 some real-time demands, meaning a high HZ value helps.  Otherwise, you can
 stick to 100Hz on a server.  Higher values won't change anything and will
 only reduce throughput (though not by much anyway, which is why some people
 set 1000Hz even on servers.)


Hmmm... I *do* feel better response (interaction-wise via SSH) if I
use 100, so I think I'll settle for 250 Hz.

Thanks for the explanation!

Nahh, I made a mistake there. 4000MB/S = 4GB/S  - You are correct, at

Of course Volker, the man with the answer to everything, just told you
that 80 mega-bit / second was a 'really, really good hard drive' so I
guess we all make mistakes. ;-)

I was really trying to point out that you ARE getting 80% of the USB

across the USB cable talking to the drive interface. Sustained storage
rates of the drive don't have anything to do with that though. That

 please read man hdparm

 For meaningful results,  this  operation
              should be repeated 2-3 times on an otherwise inactive system (no
 other active processes) with at least a couple
              of megabytes of free memory.  This displays the speed of reading
 directly from the Linux buffer  cache  without
              disk access.  This measurement is essentially an indication of
 the throughput of the processor, cache, and mem-
              ory of the system under test.


 as you can see, those numbers have nothing to do with the transport.

 And 80mb/sec for a harddisk is really, really good.

Here's what I get from the same hard drive plugged into a USB 2.0 port:

# hdparm -t /dev/sdb
/dev/sdb:
Timing buffered disk reads: 102 MB in  3.01 seconds =  33.90 MB/sec

# hdparm -t /dev/sdb
/dev/sdb:
Timing buffered disk reads: 102 MB in  3.03 seconds =  33.63 MB/sec

So USB 2.0 throughput is obviously creating a bottleneck.  USB 2.0
throughput is said to be 60 MB/s so I'm surprised I'm not doing much
better than 30 MB/s there.

USB 3.0 throughput is said to be 625 MB/s so I must be running up
against the speed of the disk itself in USB 3.0 mode, correct?  Here's
what I get from my internal SATA hard drive, but it is surely a much

B and b mean whatever the fuck the manufacturer felt like having them

manufacturers, so you have to resort to independant testers who will 
tell you that disk have usable capacity of X units, where units is an 
exactly defined thing that we all understand.

[1] There are standards, but not enforceable so manufacturers can 
often do anything they want. Japanese sound amplifiers are the same - 
I've seen portable Sony units advertised as 5,000W!

That's two hot water geysers, a stove and a few kettles of power. All

Those speeds seem good and normal to me, much faster than USB 2.0
would have provided. And really good for a low-power drive. Faster
than my USB 3.0 32GB flash drive. :)

Here's a benchmark of 2.5 USB 3.0 external drives, in fact yours is
one of the tested disks. Your speeds above are actually faster than
the benchmarked speeds:
http://www.everythingusb.com/images/list/portable-drive-large-file-copy-benchmark.png

 Here's what I get from the same hard drive plugged into a USB 2.0 port:

 # hdparm -t /dev/sdb

 So USB 2.0 throughput is obviously creating a bottleneck.  USB 2.0
 throughput is said to be 60 MB/s so I'm surprised I'm not doing much
 better than 30 MB/s there.

USB 2.0 theoretical max is 480Mbps but realistically it is more like
320Mbps, which means your speeds above are just about as fast as
anyone is ever going to get on USB 2.0, and they are in line with the
fastest speeds I've ever gotten personally on USB 2.0. Roughly about
32 MB/sec is maximum speed on USB 2.0 in my experience.

 USB 3.0 throughput is said to be 625 MB/s so I must be running up
 against the speed of the disk itself in USB 3.0 mode, correct?

Processing power of the external USB-SATA controller chip could also
come into play. But in your case I think you're getting the maximum
speed possible from the drive. Be happy. :)

Here's
 what I get from my internal SATA hard drive, but it is surely a much
 faster disk:

 # hdparm -t /dev/sda
 /dev/sda:
 Timing buffered disk reads: 412 MB in  3.01 seconds = 136.99 MB/sec

 # hdparm -t /dev/sda
 /dev/sda:
 Timing buffered disk reads: 412 MB in  3.01 seconds = 136.75 MB/sec

 # hdparm -t /dev/sda
 /dev/sda:
 Timing buffered disk reads: 414 MB in  3.01 seconds = 137.55 MB/sec

Surely a faster/higher-powered disk and I would guess that USB 3 maybe
has higher latency than the SATA controller on your laptop's
motherboard. I know USB 2.0 has latency problems (and why the audio
nerds* prefer firewire equipment).

afaict rosegarden relies on jack for it's audio processing. If no jackd is

  I removed the jack USE-Flag from make.conf temporarily and

There are some other sequencers in the pro-audio overlay.
http://svnweb.tuxfamily.org/filedetails.php?repname=proaudio/proaudiopath=%2Ftrunk%2Foverlays%2Fproaudio%2F00-

has a list of all packages. You could search this page for midi sequencers and 
try to find one that does not depend on jack.
And as suggested before there's media-sound/seq24 in portage, that only needs 
alsa to talk to synths.
jackd is really cool, if you are doing audio work. For MIDI stuff only, it adds 
nothing to pure alsa afaik.

   The JACK Audio subsystem has stopped Rosegarden from
   processing audio, probably because of a processing
   overload.  An attempt to restart the audio service has been

   In one of these short tiemes of peace and slumber I open the

   and start it again only to play another fresh match between me and
   this damned dialog... ;-/
  
  Looks like rosegarden cannot work with pure alsa. I did not know this.
  There's seq24 in portage, which seems to be a step sequencer that works

  We could try to solve your problems with jack :)
  I recommend qjackctl for jack-server handling.
  How do you start it? What use-flags are set for it?
  Another option is to try the versions from the pro-audio overlay (that's
  what I use for rosegarden, jack, ardour and some other audio related

  there's a bug in zynaddsubfx. You could try eg hydrogen to test this.

console. Unfortunately, in gnome the keyboard is resolutely stuck on US. I can 
add the
English UK layout in the keyboard preferences, and it looks fine when I first 
select
it. However they layout doesn't change and when I Show the English UK layout, 
it
shows a standard US layout.

No matter what I do (which admittedly isn't very much as I don't know X stuff 
that
well), I cannot get a decent keyboard layout in gnome.

Any tips would be appreciated before I rip all the keys off and get the super 
glue
out.

Thanks

Boot it up and see if the latest livedvd works on that system.
If it does you can glean what the livedvd-11.2 is using

Edit your /etc/X11/xorg.conf and add something like this:
=
Section InputClass
   Identifier  keyboard catchall
   Driver  evdev
   MatchIsKeyboard on
   MatchDevicePath /dev/input/event*
   Option XkbLayout gb
   Option XkbOptions terminate:ctrl_alt_bksp
EndSection
=

Or add similar lines to /usr/share/X11/xorg.conf.d/10-evdev.conf; 

Or copy your /usr/share/X11/xorg.conf.d/10-evdev.conf to 
/etc/X11/xorg.conf.d/10-evdev.conf and then add the lines above.


PS. There may be a Gnome way of achieving the same, but I only have cursory 
experience of Gnome so somebody else should advise on that.

Re: [gentoo-user] {OT} USB 3.0 hard drive speed test

2011-08-11 Thread Grant
 USB 3.0 throughput is said to be 625 MB/s so I must be running up
 against the speed of the disk itself in USB 3.0 mode, correct?

 Processing power of the external USB-SATA controller chip could also
 come into play. But in your case I think you're getting the maximum
 speed possible from the drive. Be happy. :)

I'm happy.  I just like to know where I stand relative to the spec.

 Surely a faster/higher-powered disk and I would guess that USB 3 maybe
 has higher latency than the SATA controller on your laptop's
 motherboard. I know USB 2.0 has latency problems (and why the audio
 nerds* prefer firewire equipment).

 * used as a term of endearment :)

For audio playback, USB is now just as good as Firewire thanks to the
inception of the asynchronous (as opposed to synchronous or adaptive)
USB DAC.  In an asynchronous implementation, the clock is in the DAC
itself and operates independently of the computer.  However, if
Firewire has lower latency I can see how it would be better than USB
for audio recoding and production.

The solution to such problems is: Scan the build log for the first

[gentoo-user] Assigning an IP in AP mode

2011-08-11 Thread Grant
Does anyone know how to assign an IP address to a wireless interface
in AP mode?  It can't be specified in /etc/conf.d/net because
/etc/init.d/net.wlan0 is not executed since hostapd handles the whole
thing.  'ifconfig wlan0 192.168.0.1' works but I know I've done it
before without issuing that command each time I reboot, I just can't
remember how.

BTW, can I assign IP addresses on the same subnet to the 2 wireless
interfaces in my system if one of them connects to the WAN and the
other to the LAN?

You probably don't want to do that. It will give you two connected
routes for the subnet, and only the one with the better metric will be
used, so you wont be able to communicate with hosts on the other
interface. You could probably setup bridging, but IMO it would almost
certainly be better to just use different subnets.

I could be wrong though - try it and see what happens.
