[gentoo-dev] NPTL ready yet?

[Joseph Pingenot]

Hello.

Is NPTL considered ready to use yet?  I've finally gotten 2.6 to work, and
  I can't wait to get full use o the threading improvements.  :)

I have been using it for 3 or 4 weeks, with nvidia drivers and mm-sources, no problems at all.

Whats involved in updating a non-NPTL glibc to NPTL glibc?  Just
"USE=nptl emerge glibc" or do other libraries and binaries need to be
re-emerged also?

Also, do you know if the nvidia drivers work with
development-sources?  (My guess is they do?)

Thanks,

Matt

no, just re-emerging glibc with nptl in USE is enough

if by development sources you mean 2.6.x then yes, they have since 2.5.x

oh, and here's my thumbs up to using NPTL ... ive been using it since 2.5.x 
and havent found significant bugs ... and/or any that havent been fixed so 
far ...

I used NPTL for about four weeks and had no problems except that canna, a 
Japanese input server, would not start. Other than that, I didn't detect any 
change in the system, performance-wise or otherwise.

As far as I know, only OpenOffice and Sun JRE/JDK have support for NPTL. 
Wouldn't these need to be re-emerged to take advantage of it?

I don't know about openoffice remerging. Basically the support consists 
of making openoffice compile on nptl based systems. An allready compiled 
openoffice should though run fine with nptl.

It seems that the same is true for the j2sdk java source package (looking 
at the patch). It could be however that the headers from the nptl 
implementation of pthreads allow better optimization, but I don't know. 
In that case you would need to recompile everything that uses the 
pthread lib.

AFIAK, you do not need to recompile anything to use it - anything using
libpthread will use it.  You may however have issues recompiling things
as there was some changes, and things heavy dependent on how
linuxthreads worked (valgrind, gdb, etc) may or may not misbehave, but
mostly the rest works just fine.

Have you been able to get java working?
Last time I compiled glibc with NPTL,  javac crashed constantly (with both sun 
and blackdown jdks).

I had this issue as well, but it was pretty much an odd problem that
surfaced on any gcc3 system back then (except if we are talking
different issue, but then I have been using NPTL for close a year now,
and cant remember issues like that), and not NPTL specific.

To that respect, is there a good 2.4 NPTL kernel that you can recommend?

You will have to look toward getting a Redhat kernel into the tree, or
possibly try to rip the critical patches out of one ...

Whelp, it looks like, as of last night, it's not.  Enabling nptl hosed
  devfs, at least.  Which makes me rather unhappy, since I then can't boot.
  ;)
It looked like the build didn't go so hot anyway, for whatever that's worth.

i use devfs in NPTL w/out any problems ...
you can boot w/out devfs ;)
i use udev currently ... that isnt devfs ...

I got an error when devfs was linking to libc, it was missing a symbol
  related to GLIBC, iirc.  I don't have it written down, unfortunately.
