and projects
This
page contains the patches necessary to build the same kernels I
utilise for every day use. For me they are generally stable, and
weeks at a time uptime can be expected with a full-featured
configuration, but I cannot assure months at a time stability that
one might expect from a seasoned Linux distribution kernel.
Having said that, I have clients running production networks
networks using 2.6.15-vz2.1 based kernel with over 6 months
uptime. Generally after .vz feature adds these kernels will
lean towards RedHat Fedora Core flavour; PlanetCCRMA is a strong
influence, also Con Kolivas. As always, use at your own risk. I
have trashed file systems because of bugs that I have introduced
while building and testing some of these kernels. To my knowledge
I have never released a kernel to the website with such serious,
damaging bugs. All kernels are tested in desktop usage environment
before release.

About LateralBlue
Lateral Blue is a studio project with music roots derived from dance music and electronica and influenced by a broad range of genres.
On the technological front the studio's roots reside in the Commodore Amiga platform and Music-X MIDI sequencing software. Amigas are still in limited service. A 50Mhz 68030 Amiga1200 with 32Mb Fast RAM driving miscellaneous MIDI sound sources was the prime sequencing engine for "A Time of Trancefer".
Originally dedicated to audio projects and the production of, Lateral Blue has diversified into performance and recorded media production including video, lighting, live engineering, and limited software development in maintaining a linux based studio network.

Fun with HP hardware - Have a HP DL server? Use Fedora? Want to use the excellent HP system management homepage, but can't get it installed? Here's how : First off download the appropriate HP support pack for your server and Fedora OS - FC5=RHEL5, earlier versions you might need to try earlier RHEL support packs.
mv
/etc/redhat-release /etc/redhat-release.old
touch
/etc/redhat-release
edit redhat-release to read "Red Hat
Enterprise Linux Server release 5 (Tikanga)"
The HP web site will tell you the supported RHEL kernel. Find a source rpm and build then install and boot the appropriate RHEL kernel for your system
You can now
successfully install the support pack from it's install script. In
addition, your system now superficially appears to be RHEL5 rather
than FC. When I have tested what happens when I switch the
redhat-release string back and run a stock FC kernel, I will
report further.
this is, of course, totally unsupported;
but it works, at least on the DL380 hardware it was tested with.
Will post for ML150 and others if there are significant
differences.
MultiConsole X how-to document Updated 6 Feb 2006 (added USB VGA console note)
This will need updating for FC5 and the latest builds of Xorg and gdm. FC5 xorg no longer requires patching, and the gdm config file format is much much tidier.
NEWS : nVidia latest "Legacy GPU" 9631 driver version is very stable and resolves PCI bus performance issues impacting real-time performance and pro-audio compatibility.
(Latest)mad plan: Enterprise 2.6.18 kernel with the usual -vz adds, with the exception of those known to tend towards the flakey in testing - so vesafb-tng, as lovely as it looks when it works, is on shakey ground for this one.
Latest
2.6.21-vz.CFS-1.0.4
Beware
faketty vt assignment changes during kernel upgrades in multi-seat
arrangements. For one specific config 2.6.16 -> 2.6.21 upgrade
3 console config changed from using vt50/52/54 to vt54/56/58
...this may vary between installations.
Many thanks to Aivils Stoss for faketty maintenance, the 2.6.21 patch should apply broadly for kernel trees >2.6.17

faketty_hijackled-2.6.16.9
'production candidate' realtime kernel : 2.6.16-vz.RRT-1.3.3
IRQ
Priorities of a generic x86 PC, highest priority to lowest :
0,
1 ,8, 9, 10, 11, 12, 13, 14, 15, 3, 4, 5, 6, 7
There
is a reason for the weird order; it boils down to legacy support
as the architecture evolved. For best (real-time) multimedia
performance, PCI audio should be assigned the highest possible IRQ
priority available, generally IRQ 9. The IRQ routing may be
selected in the BIOS configuration of many PC's; generally on a
slot for slot basis. Bear in mind IRQ sharing when selecting a
slot for your devices and the IRQ to assign the slot; an IRQ
setting may for instance be assigned to PCI slots 1 & 5, 2 &
6, with onboard devices and AGP often sharing with other PCI
slots, slot 3 perhaps being the only slot that doesn't share.

2.6.16-vz.RRT-1.3.3
Real-time
pre-emption
Derived
from PlanetCCRMA distribution for multimedia use, in particular
pro-audio multi-track recording. Greatly improved stability over
previous 'experimental' real-time kernels; with a good
configuration, this kernel works well for a recording platform.
Higher risks of lockups thanks to real-time kernel pre-emption. In
practice, this has been observed intermittently with nVidia video
init only so far. The core kernel tree is Stanford Universities
PlanetCCRMA distribution
"edge" kernel.

Notes : gcc-3.4.2 (Fedora Core 3+) inlining compile failure , ATI and MCE LIRC-usb issues; use USB subsection drivers, netpoll compile failure with incompatible .config
If you have compile problems not listed as a known issue try this example .config suitable for 2.6.9 patchsets. This is not a generic .config, you will need to at least check that the CPU type matches your hardware; 'make oldconfig && make menuconfig' or similar - This config good for most desktop hardware with minimum changes. Check Silicon Image SATA driver if you also use it and want a module...it is compiled in. There is a netpoll compile dependency to be wary of if you are playing with the network configuration. Sorry, I have not tracked down the culprit code.

Ruby
: These
patches should apply cleanly to kernel.org or -vz kernels. Ruby
should peacefully co-exist with current faketty, providing a
choice or combination usage (ruby for MDA text console, faketty
for X consoles). Currently untested with vz kernels later than
2.6.12.
