unmodified_drivers for linux-2.4 kernel

unmodified_drivers for linux-2.4 kernel

[Michael Williams]

I need help trying to compile the unmodified_driver tree for use on a 
HVM linux-based pc running kernel 2.4.34.  I found this  ( 
http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00719.html 
) thread and it seems that these patches are what I need, but I cannot 
get them to compile on my machine.  If Ben Guthro or anyone else who was 
able to successfully use these patches could tell me what I need to do 
to compile them, I would be very appreciative.

My xen version is 3.1.0-53.1.14  (CentOS 5).

Any and all help is appreciated.

Ben is out of the office until next week.  The patches that Ben originally posted for 2.4 were actually developed for RHEL3 in particular.  In parallel with our own efforts, RedHat has been working on a set of patches of their own for submission to xen-devel (http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00811.html).  We expect to see these in the near future.

These patches were originally developed for RHEL3-U8... I'm not sure 
what the differences are for CentOS5. I'm sure it would take a bit of 
development to get them working.

The guys over at RedHat had said they were planning on releasing a 
pv-on-hvm driver kit for older RHEL versions...but I'm not sure what the 
status is on these.

However - you are not the first person to inquire about these patches - 
indicating that there is a real desire to support 2.4 kernels.

Keir - you had originally rejected these patches for various reasons.
Have any other solutions been proposed that you find more acceptable?

We would definitely host a repo for 2.4 drivers. But we don¹t really want to
scuzz up the main drivers with too much legacy stuff. Particularly since
they will go away when we move to pv_ops, and mainline Linux does not like
carrying legacy layers in driver sources afaik.

Re: unmodified_drivers for linux-2.4 kernel

[Michael Williams]

[-- Attachment #1.1: Type: text/plain, Size: 2513 bytes --]

The sytem I am trying to get the unmodified_drivers to work on is 
actually a custom linux distribution based on the 2.4.34 linux kernel 
with several other patches applied to it.  I have already investigated 
trying to apply the xen patches to the kernel itself, and the patches 
conflict with the grsecurity and/or openswan patches.  So, in the 
meantime I have been running the machine as a pure HVM, but I am looking 
for ways to increase it's performance.

If there is anything that I can do to help with this project, just let 
me know, and I will help out to the best of my ability.
