Description Chris Lalancette 2007-10-08 17:38:23 UTC

Description of problem:
Xen 3.1.1 includes a number of patches to fix up PCI front/back handling,
especially for ia64.  These changesets are: 15083 and 15392.  They are a little
bit scary in that they add a whole new "controller" to ia64.  We can add the
controller, but I'm not sure if we can enable it in the config since it might
break kABI.  Kei, can you take a look and give us your thoughts on it?

Comment 1 Tetsu Yamamoto 2007-10-09 21:08:45 UTC

Cset15083 is just to initializing the variable, so it does not break kABI.  As 
for cset15392, we are now trying to check on PRIMEQUEST/Tiger4 that it does 
not break kABI.

Comment 2 Tetsu Yamamoto 2007-10-15 15:15:15 UTC

Fujitsu Xen team in Japan has tested cset 15392 with a driver domain, and 
confiremd that it has no problem and works fine.

Comment 3 RHEL Program Management 2008-02-01 22:40:08 UTC

This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".

Comment 4 Bill Burns 2008-04-30 13:05:09 UTC

Where are we with these? Did they make RHEL 5.2? Or are they desired for 5.3?

Comment 5 Tetsu Yamamoto 2008-04-30 15:16:52 UTC

These are not in 5.2, so desired for 5.3.

Comment 8 Chris Lalancette 2010-07-19 13:48:37 UTC

Clearing out old flags for reporting purposes.
