hi seppe, can you add usb patches from -bk snapshots?

I have another patch for fixing kernel oops when using an usb-storage device such as dvd writer or harddisk.

::: [13:13:24] <seppe_> I cant suspend from X, but I made a small script which exits X, suspends and calls X back when I resume .. now I start up in less than 8 seconds

post it

[aderio]

Downloaded, compiled, booted, works (with nvidia-kernel). I'll do some stability testing later.

Double thanks Seppe

Update, just finished emerge -uvDp world and grabbed some updates compiled and 2.6.9-nitro1 still a solid as a rock

[desertstalker]

Errm. I get two failed hunks when I try to apply the swsusp2 patch??

I'll see if I can fix it (don't hold your breath)

[seppe]

::: [13:13:24] <seppe_> I cant suspend from X, but I made a small script which exits X, suspends and calls X back when I resume .. now I start up in less than 8 seconds

post it

First, the suspend script from http://softwaresuspend.berlios.de is extracted in /etc/hibernate

/etc/hibernate/suspend.sh contains:

Code: Select all

#!/bin/sh
#
sh /etc/hibernate/suspend2.sh &
/etc/init.d/xdm stop

chmod +x /etc/hibernate/suspend.sh

/etc/hibernate/suspend2.sh contains:

Code: Select all

#!/bin/sh
# 
sleep 1
radeontool light off
sh /etc/hibernate/hibernate.sh
/etc/init.d/xdm start
/etc/init.d/alsasound restart

chmod +x /etc/hibernate/suspend2.sh

/etc/hibernate/hibernate.conf contains:

Code: Select all

UseSwsusp2 yes
Reboot no
EnableEscape yes
DefaultConsoleLevel 1
Verbosity 0
LogFile /var/log/hibernate.log
LogVerbosity 1
Distribution gentoo
SaveClock yes
IncompatibleDevices /dev/dsp /dev/video*
Unmount /windows 
Mount /windows
UnloadAllModules yes
UnloadBlacklistedModules yes
LoadModules auto
GentooModulesAutoload yes
DownInterfaces eth1
UpInterfaces auto
StopServices alsasound
StartServices aumix
LeaveXBeforeSuspend yes

So I restart all services (don't worry, they load a LOT faster) and I unmount /windows when I hibernate so I can still access my Windows partition when I boot Windows after I hibernated. I stop alsasound in hibernate.conf but I restart it manually (in suspend2.sh script) so that X loads up faster.

radeontool light off turns off my screen just before hibernate starts, that is because otherwise I get ugly messages on my screen So this is not really needed

As you can see, I stop and start X with /etc/init.d/xdm, because I use gdm (should work as well with kdm or entrance)

now execute /etc/hibernate/suspend.sh to start it

With this configuration, my system boots up within 8 seconds. That is also because X is preloaded (I use LDFLAGS="-Wl,-O1"
in /etc/make.conf, but you can also use prelink). I guess all this also works for non-laptop systems. So if you want to boot really fast, check this out

Grabs it no if its better than rc2.nitro2 its superb

configurable-hid-mouse-polling-2.6.9-rc4.diff | usb 500hz mouse hack

Hey!

You might want to include revision 2 of my patch, instead of revision 0 in the next nitro.

Revision 2 now includes the possibilty to change the polling interval with either a module parameter (if usbhid is built as a module), or a boot parameter (if usbhid is built into the kernel), if the polling interval you chose in CONFIG is either too low, or too high. Even more tweakability, yay!

Grab it off here:

http://omfg.linux.dk/pub/configurable-h ... e-polling/

Thanks

EDIT:
I changed the revision numbers, since i just released revision 2 with a tiny bug fix...

[Deranger]

Oh yes! New Nitro! I'll compile it right now and post results later!

Thank you, Seppe!

[mercurator]

Hi,
I'm thinking of giving nitro sources a try. So what do I do? I suppose I have do download 2.6.9 kernel from kernel.org, patch it with the nitro patch, but then what? What do I do with the ebuild file?

Thanks guys!

[Deranger]

First of all, set PORTDIR_OVERLAY="/usr/local/portage" in your /etc/make.conf, then just:

Code: Select all

mkdir -p /usr/local/portage/sys-kernel/nitro-sources && cd /usr/local/portage/sys-kernel/nitro-sources && wget http://www.sepi.be/nitro/2.6.9-nitro1/nitro-sources-2.6.9-r1.ebuild && ebuild /usr/local/portage/sys-kernel/nitro-sources/nitro-sources-2.6.9-r1.ebuild digest && emerge nitro-sources

When that's finished, you've emerged nitro-sources succesfully!

Then you can configure it just like ordinary kernel...and don't forget to fasten your seatbelts before booting

Have fun!

[ EDIT ] Oops, link was pointing to old version, fixed now!

[Phlogiston]

Hi at all

I'll try this new nitro and hope that it will solve this annoying problem:

downloading now, i can't wait to get framebuffer working right again.

how often does a new nitro release come out?
this is my first week using it, and this is the third release, i don't know if i can keep up

Impossible, the previous release was more than 1 week ago

I try to release one each week, if I have the time

[discomfitor]

The alsa patch that I made for the previous kernel (http://darc.ath.cx:81/linux/alsa-update.patch.bz2) still applies cleanly and is much newer than the -mm bk patch. You should include it in future -nitros.

[fimbulvetr]

Oktane,

Not sure if you knew this, but instead of doing:

Code: Select all

mkdir /usr/local/portage && mkdir /usr/local/portage/sys-kernel && mkdir [code]/usr/local/portage/sys-kernel/nitro-sources

[/code]

You can just do

Code: Select all

mkdir -p /usr/local/portage/sys-kernel/nitro-sources

where -p means "make the parent directories".

[Cagnulein]

thx seppe...but it doesn't works for me....susped works great, but when i try to turn on the pc, the suspend screen freeze at 70% T_T

[Cagnulein]

i solve the problem with swsups enabling the debugging support and Relaxed /proc/software_suspend permissions

i think my sense of time is a little skewed. too bad you can't run NTP on a person.


a question about framebuffer:
i have vesa-tng enabled
and the drivers for my card enabled.
if i use the original vesa driver, vga=795 works great.
if i use the vesa-tng drivers, i get an unknown video mode error. if i just let it boot with no vga parameter, it fills the screen and then stops.

any ideas?
i'm rather confused about the two ways it seems that people are passing framebuffer info.
i've seen the vga=795 method
and the video=vesafb-tng,ywrap,mtrr,1400x1050-32@60

neither seems to work for me. please forgive if i'm making a stupid mistake.

[BulletSponge]

ok, it seems that i've made a tad bit of an error,
if i go to 1280x1024 in the parameter format, it works.

but the monitor should be able to run at 1400x1050, and it does so in x.

[m0sia]

again a lot of problems:

1) usb 1.0 flash stick don't work.
"mount: /dev/sdb1: can't read superblock"
usb2.0 works like charm

motherboard: p4p800se
2) vesa-tng works like $%!@!
Sometimes it freezes at boot on identifing gpu.
sometimes it doesn't work if i plug tv in tv-out.
it doesnt work if i switched back to console from xorg(nvidia-6111).

3)annoying messages in syslog(of cource i can turn off preemptible support):

2: vesafb-tng doesn't work/is unstable on SMP systems (in other words a hyperthreaded p4)
