Here you go :)
Thanks and sorry for being a bit late getting back to you -- didn't
get around to it before leaving for OLS.
I've tried the patches now and I seem to not get very far with them applied :-(
- once I build a kernel with CONFIG_FB and CONFIG_XEN_FRAMEBUFFER
enabled, I don't seem to get any output on the xen text console
anymore. I've tried quite a few combinations of xencons and console
on the command line but didn't find one that worked.
- running vncfb and connecting a viewer works and I get the console
output, but the kernel seems to get stuck as soon as it does any kind
of busy waiting -- I obeserved this while the 5 second tls banner was
printed (it never got to 4, eventualy softlockup kicks in) and after I
moved /lib/tls out of the way, it got stuck in a similar way when
setting the hardware clock (doesn't make sense in domU, but should get
the machine stuck either -- works without the framebuffer changes
applied). This is all running debian in the domU.
Do you have any recommendations how to get to a working setup and can
you look into these issues?
I'm also attaching two patches:
- vfb-xenbus-transaction.diff: change xenbus_transaction_t to its
non-typedef'ed form since the typedef'ed form doesn't exist anymore.
- vncfb-makefile-changes.diff: change the vncfb Makefile such that it
works like other tools Makefiles.
We'll also need integration with xend before this is really useful, at
least a way to start vncfb (should be similar to how we start qemu for
hvm guests) and support for starting a vncviewer from vncfb would be
nice (see tools/ioemu/patches/vnc-start-vncviewer).
