Hi. In the recently merged gspca branch, a couple of header files are missing (or I pulled from the repo too early  ). (Just copied them from the gspcav1 source tar ball.) -
| Quote: | linux-2.6.24-rc6-zen0/drivers/media/video/gspca/Vimicro/ov7620.h
linux-2.6.24-rc6-zen0/drivers/media/video/gspca/Vimicro/mc501cb.h |
Meanwhile, less than half an hour from my first boot of a 2.6.24 kernel. Muhahaha ^ ^. (Also, as mentioned, madwifi-ng requires some fixing as yet.)

Could you guys do a bisect to check in which commit this error appears?
PD: gpsca headers added. |

There is something strange :

git bisect good v2.6.24-rc5-zen1

I will try to use bisect - but I have no experience with it and it will take some while (I'll be doing it along with work / parallel) 
is the approach from http://michael-prokop.at/blog/2007/02/03/bisect-probleme-debuggen-mit-binarer-suche/
the right one ?
| Quote: | Source holen:
% git clone git://www2.kernel.org/pub/scm/linux/hotplug/udev.git
% cd udev
bisect initialisieren:
% git bisect start
% make clean ; make ; $TESTEN
Der aktuelle Source (master-Branch) macht den Stress? Dann als böse markieren:
% git bisect bad
Auf eine funktionierende Version stellen (siehe 'git log', $commit-id auswählen und als $branch_name markieren):
% git checkout -b $branch_name $commit-id
Klappt das mit $commit-id noch? Testen und als gut markieren:
% make clean ; make ; $TESTEN
% git bisect good |

sorry for the noob question.. but..
i reverted the asm unified nop patch, using git revert, but the kernel won't compile anymore (maybe other patches relayed on this one)
now what i want to do is repull the patch that i reverted... how can i do that? i think a way it's just to do another git revert on my previous revert (lol) but i think there may be a cleaner way
i tried git reset and git checkout -f but it won't pull the patch :\ |

| Posted: Sat Dec 29, 2007 6:53 pm Post subject: Realtime capabilities? |
|
|
Hey, just complied and installed, boot went fine on first try which is great. Everything seems to be working short of realtime. As I understand it, the Realtime Capabilities under security options is basically the same as the realtime-lsm module that can be emerged from portage. I was using this, in combination with Default Linux Capabilities security model to run the jack server in realtime under 2.6.23 Gentoo Sources. Now I'm running 2.6.24-rc6-Zen0 and have complied with Realtime Capabilities. I can see /sys/module/realtime/parameters/gid and echo 18 > /sys/module/realtime/parameters/gid, gid 18 being my audio group.
When I execute jack --realtime -d alsa though, I get...

Now I basically had the realtime-lsm module setup to do the same (modprobe realtime gid=18 ) and everything worked fine. I've double checked, my user is definitely still part of the audio group and GID for audio is 18. Is there a different procedure I need to follow for this setup or does anyone have any ideas what might be going wrong? Thanks. |

This converts the ptrace/signal accessors for i387 math_emu
state to the user_regset interface style, and calls these
from the old interfaces.
It also cleans up math_emulate's ptrace check to be a
single-step check, which is what it really wants.

Should that be :

Automatic revert failed. After resolving the conflicts,
mark the corrected paths with 'git-add <paths>'
