[12:24] <BenC> kylem: The kernel ends up needing a unsigned 64-bit cmp function from libgcc
[12:24] <BenC> __ucmpdi2 to be exact
[12:25] <BenC> it's something in v4l2
[12:25] <kylem> ok
[12:26] <BenC> it'll show up in modpost
[12:26] <BenC> I don't understand why x86_64 and sparc64 didn't already show it
[12:27] <BenC> oh, well, probably because di2 isn't needed on 64-bit
[12:27] <BenC> well, it didn't show on x86 :)
[12:28] <kylem> is it ppc64?
[12:28] <BenC> nope, ppc32
[12:29] <kylem> ok.
[12:30] <kylem> could just disable that on ppc i suppose...
=== kylem ducks.
[12:30] <BenC> hehe, could just disable ppc :)

[03:06] <BenC> kylem: I'm not sure if it's correct, but it may be that getting __ucmpdi2.S from gcc would be the right thing
[03:07] <kylem> i think i remember you just needing to pull something from libgcc.
[03:19] <BenC> I'm talking with benh now...hoping he has some ideas

[04:41] <kylem> i think that ought to work, from what i recall doing on parisc.
[04:43] <kylem> void foo(void); EXPORT_SYMBOL(foo); is pretty evil, i think it will work for my atheros hack too.
[04:43] <kylem> since gcc takes care of the calling convetions for those, all we need to do is make sure it gets linked.

[03:44] <jerom1> When i add theses packages in my kickstart linux-headers-server, linux-image-server, linux-source my initrd is failed after reboot. Have you an idea ?
[03:59] <BenC> in kickstart? You mean like for an install, or what?
=== BenC does the "lrm is building" dance
[03:59] <kylem> whoo
[04:00] <jerom1> benC : yes i use kickstart with PXE boot for install HP Proliant DL360 G5 Server
[04:02] <BenC> jerom1: And is it the initrd for the installer, or after you install and reboot, that is failing?
[04:02] <jerom1> it's failed after my install and reboot
[04:03] <BenC> and what's the failing message?
[04:04] <jerom1> unmoutable device ... kernel panic after reboot

[05:32] <kylem> mjg59, it's the right answer on a whole lot of platforms.
[05:32] <kylem> the "right" answer is shooting the v4l author.
[05:32] <mjg59> Really? Ouch.
[05:32] <BenC> mjg59: It seems to be what othr architectures do
[05:32] <BenC> mjg59: It's pretty much the same as taking the .S for that op and compiling it with the kernel
[05:32] <mjg59> Yeah
[05:32] <kylem> we /aren't/ linking libgcc.
[05:33] <kylem> it will just take the specific functions it needs from the .a
[05:33] <kylem> and throws the rest away.

[07:05] <kylem> sorry, was eating lunch
[07:06] <mjg59> BenC: Hi
[07:06] <BenC> mjg59: Can you look at the release/completion patch we have in some of the pcmcia controller drivers and tell me if we still need them?
[07:07] <BenC> I'm getting a softlockup in i82365 on my P4 and I think it might be related to those changes
[07:08] <mjg59> release/completition patch?
[07:10] <BenC> it adds a release() call back to the platform device, and it calls complete()...module exit does a wait_for_completion() on it
[07:10] <BenC> it's was suspend related, IIRC
[07:10] <BenC> been around since breezy I think
[07:11] <mjg59> Uh.
[07:11] <mjg59> Not actually sure if it was anything to do with me.
[07:11] <BenC> I thought I remembered you asking me to put it back in dapper because I left it out...maybe I am misremembering :)
[07:11] <BenC> if you don't know anything about it, I'm killing it
[07:12] <mjg59> Looks like it came from http://lists.infradead.org/pipermail/linux-pcmcia/2004-March/000598.html
[07:13] <BenC> that patch isn't causing the softlockup anyway
[07:15] <BenC> I think that's uneeded now...the drivers are using platform_device_alloc() which has:
[07:15] <BenC>                 pa->pdev.dev.release = platform_device_release;
[07:16] <BenC> oops, I didn't actually use the unpatched one...reverting that patch fixes it
