2.6.18-rc4-viper1: Ah, Now That Hit The Spot | Plugsched!

Viper Sources is pretty much my playground for new patches.

The main goal of this patchset is pretty much the same as E-Mission Sources: to
offer latest features, decrease latencies, decrease overhead, and improve interactivity. The only difference is experimental versions of everything. I boot test each release and run for an extended amount of time.

/* Notes */
Alot of changes in this version, I've been in contact with Peter Williams lately, the creater of Plugsched,
he claims that all schedulers are running at or around 100% performance, so I thought I'd give it a shot.

Added in latest genpatches, plugsched, iosched fixes rollup, newer lockless, ck desktop patches,
and build fixes. No extra fixes are needed to 'emerge ati-drivers'!

I was hoping it was because I am using Ubuntu rather than gentoo on this notebook and the compiler versions are different.

affected line is: include/asm-i386/types.h:4:typedef _Bool bool;
problem is from the generic-boolean.patch

Ran some tests with interbench. So far, Staircase CPUSched is running as well as vanilla. But Nicksched's latencies shine! I recommend you guys to give Nicksched a try with this release. It is running smooth as silk here

Nice, this kernel works great. I've been dispointed with the 2.6.17 kernels but this one is nice and Nickshed makes it even better!

thanks,

#uname -a
Linux neuros 2.6.18-rc4-viper #1 PREEMPT Fri Aug 11 20:58:23 CDT 2006 i686 Intel(R) Pentium(R) M processor 1.60GHz GNU/Linux

et voila - nicksched is in place for the time being and so far very nice. MMC support, vmware kernel module, ati-drivers build perfectly.

system config: SATA, firewire, usb-storage, ipw2200, ext3+reiser+XFS+fat32, SD/MMC reader, ATI Radeon X300
external modules working: ieee80211, ipw2200, ati-drivers, arpstar (built, not tested), kqemu (qemu kernel module, tested), vmmon (vmware kernel module, tested).
still broken: shfs (does anyone know the status of this project, it seems to have been last updated Feb 2006)

so far my overall impression is... :-D

I thought what the hey, I'll give it a go in my Gentoo VM running on a Windows XP host.

Linux gentoovm 2.6.18-rc4-viper #1 Mon Aug 14 16:23:41 EST 2006 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GNU/Linux using Nicksched is running sort of OK with one glitch. The VMWare tools software must be recompiled for the running kernel. This has worked flawlessly so far for gentoo-sources and emission-sources.

I get the following error with viper-sources when trying to compile VMwareTools-1.0.0-28343...
/tmp/vmware-config5/vmhgfs-only/driver.c: In function `HgfsChangeFileAttributes':
/tmp/vmware-config5/vmhgfs-only/driver.c:763: error: structure has no member named `i_blksize'
/tmp/vmware-config5/vmhgfs-only/driver.c: In function `HgfsInitializeInode':
/tmp/vmware-config5/vmhgfs-only/driver.c:835: error: structure has no member named `u'
etc...

Any clues?

Great to see a kernel with nicksched back again.

A useful tweak for nicksched is to set the base_timeslice to a value lower than 256 such as 128 or 64 for better interactivity.64 can cause problems with some applications though, so its safer to set it 128.

With those patches it removes the i_blksize from the block structure, but I've found that plenty of file systems still make calls to it. Just remove them and you should be good.

I keep getting odd issues with Alsa. Sometimes when I boot the kernel, I get errors to where my sound plays really low/slow after loading into desktop, and if I reboot sometimes the problem fixes itself, sometimes it remains. This happens whether I load my alsa driver in the kernel or as a module. Anyone else see this issue?

I'm using the ice1724 driver BTW for an M-Audio Revolution. Doesn't happen with ck source kernel or gentoo's.
