Overruns are killing my recordings.

Overruns are killing my recordings.

[Avuton Olrich]

Hello,

I've been plagued by overruns, I know it's probably linux device
driver issues, but wanted to see if anyone could possibly help me find
the heart of the issue:

I have ecasound output (at bottom) to show that it's getting
interrupted for up to 6 seconds, and all I really need to know is how
I figure out what the problem device driver is, so I can file a more
specific bug.

Computer: A7N8X Mobo with Athlon 2700+

ecasound utilizes jack if it's on, which I don't really need so I
don't run it, but it is taking advantage of SCHED_FIFO. But truely
this is not what I'm trying to get to. I have something in this
computer that is interrupting everything +/- 6 seconds and I'd like to
find out what it is, I'm really just not sure the best way to find out
what the 'offender' is.

Are you trying to record from the onboard nforce sound device or the
Audigy?  Do you have the same problem with the other device?

Make sure ecasound isn't doing something stupid like writing to the disk
from the audio thread, setting the disk IO thread to SCHED_FIFO, passing
data between the audio capture and disk threads in a non RT safe manner,
etc.

Also why are you using an -mm kernel?  It's highly experimental.  Most
audio people use the -rt kernel.

aggh. Sorry for all the noise,

I have all my drives on a linear raid and I had hdparm set to put my
IDE drives to sleep after a while, I didn't put it together because it
was happening in the middle of recording.

Thanks for the help,

Hey, I think it's a testament to the progress that has been made in the
past year and a half that people now consider audio dropouts in a "known
good" app like ecasound to be a kernel bug.  For the longest time the
answer was "linux isn't an RTOS, deal with it".

Lee, et. all,
   Could this possibly be part of what is causing my xrun problems? I
had a huge rash of xruns yesterday. I seem to run into issues after
longer times of inactivity. I hadn't considered this possibility
before.

   Unfortunately I don't know how to fix this for SATA drives? hdparm
doesn't say much and sdparm gives me info I don't understand:

lightning ~ # hdparm /dev/sda

/dev/sda:
 IO_support   =  0 (default 16-bit)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 30401/255/63, sectors = 250059350016, start = 0
lightning ~ #

lightning ~ # sdparm /dev/sda
    /dev/sda: ATA       ST3250823AS       3.03
Read write error recovery mode page:
  AWRE        1  [ sav:  1]
  ARRE        1  [ sav:  1]
  PER         0  [ sav:  0]
Caching (SBC) mode page:
  WCE         1  [ sav:  1]
  RCD         0  [ sav:  0]
Control mode page:
  SWP         0  [ sav:  0]
lightning ~ #

Drive performance seems good:

lightning ~ # hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   2200 MB in  2.00 seconds = 1100.12 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for device
 Timing buffered disk reads:  198 MB in  3.03 seconds =  65.45 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for device
lightning ~ #

I'm still waiting for someone to address the problem where I cannot
build 2.4.16-rc5-rt7 so this is on -rt3.

Thanks,
Mark

I really doubt it.  It's more likely that the xruns are caused by a bug
in the new ktimers system.  I am seeing "xruns" here too with -rt1, but
the latency tracer does not report anything over ~120 usecs.  Previous
to all the ktimers/HRT stuff going in, I was xrun free for months.

The reason I think it's a ktimers bug is because sometimes JACK reports
an xrun of negative length which I'd NEVER seen before.

I suspect this might all be fixed in the latest -rt patch but I have not
had time to build it.

OK then I'll just hang tinght. I've not seen any response on the email
I sent about 2.6.14-rc5-rt7. I cannot build it. It fails like this:

This is a new failure here since -rc5-rt3.

I don't have a 64 bit machine to test on, but the following patch should 
at least make the compiler happy.  This is the only place outside of 
seqlock.h that SEQLOCK_UNLOCKED is used, btw.

If this kernel gives you the 'BUG in get_monotonic_clock_ts' and 'time
warped' warnings, then you may want to look at the '2.6.14-rc4-rt7' lkml
thread for Steven's patch to fix the false positives.

William,
   Thanks for trying but this patch has only uncovered mare problems
for me. Since it's Friday evening and I won't have much more time I
think that since 2.6.14 is out I should just wait for Ingo to release
patch-2.6.14-rt1 and we'll see how it goes from there.

   As for what I'm seeing here's what I have after the patch:

<SNIP>
        struct clocksource clock;
};

extern struct vsyscall_gtod_data_t vsyscall_gtod_data;
struct vsyscall_gtod_data_t __vsyscall_gtod_data __section_vsyscall_gtod_data;

extern seqlock_t vsyscall_gtod_lock;
seqlock_t __vsyscall_gtod_lock __section_vsyscall_gtod_lock =
SEQLOCK_UNLOCKED(__section_vsyscall_gtod_lock);


#include <asm/unistd.h>
<SNIP>
