2.6.4-rc2-mm1

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.4-rc2/2.6.4-rc2-mm1/


- Added Jens's patch which teaches the kernel to use DMA when reading
  audio from IDE CDROM drives.  These devices tend to be flakey, and we
  need lots of testing please.

- Re-added the device mapper update

- Brought back Ingo's patch which permits remap_file_pages() to set the
  memory access permissions on a per-page basis.  This is mainly interesting
  for its very significant performance benefits to UML.

  Breaks the build on most architectures.  There are how-to-fix-it
  instructions in the changelog.

- A new version of the patch which permits ext3 quota updates to be fully
  journalled.

Was the DMA patch for CDROMREADAUDIO reading? I don't seem any speed
increase while ripping with cdparanoia.

i didnt notice anything either, but that is because mine went to 32x
anyway, which is my cdrom maximum ;)

How about CPU utilisation? vmstat output should do the trick.

This seems to work okay. When ripping a CD, cdparanoia's CPU utilisation
 never peaks beyond 4.0%. Very nice.

No crashes so far. I'll try some bad discs and see how it recovers.

Hi,

the bk-acpi.patch leads to following warning:

In file included from include/asm/fixmap.h:18,

The attached patch fixes it by including <asm/system.h>.

If your CPU was fast enough you will not see a speed increase, you
should see system time go way down though. So try and time cdparanoia
rip + encode session instead, that way you'll be using your CPU for
something worthwhile while ripping the data (you'll be doing that if you
use grip, for instance).

Yeah it does work, system time is less than one second. Thanks a lot for
the patch.

Works great on my VIA KT133A with Toshiba SD-M1502. Grip cpu usage is 5 % 
instead of 90 %.

I can't figure out why my ripping speed is so slow though, I'm getting a
3x speed with paranoia, around 6x without jitter correction. Any ideas where the problem might be?

Probably the drive, not all drives are happy with reading cdda really
fast...

The Linus patch apparently has a half-done fix - it does it in smp.c but not
in io_apic.c - so building non-SMP we get:

Yes, this is the proper fix, thanks.  It's already in my bk-usb tree
now.

Just an ack that this does fix the problem I reported against the -rc1-mm2
version of the queue-congestion stuff...
