Working on it. :-) The files rXXXXXX.patch are commits I've already made to HEAD but which weren't in 9.0-RELEASE. The others I hope to merge into FreeBSD in some form: * blkfront.patch makes us compatible with the multi-page request ring protocol used by Amazon's blkback and I'm waiting to confirm that I reverse-engineered that protocol correctly; * uart.patch is a workaround for a bug in the version of Xen which Amazon is using, but it's a really ugly hack so I'm hoping some more talented device driver hackers can improve it; * tcp_mbuf_chain_limit.patch limits the length of mbuf chains sent via TCP TSO due to limits in the linux netback driver, but currently it unconditionally limits all TCP connections -- I need to talk to network stack people about how the max-chain-length value should be passed from the network interface up the stack to the TCP code; * ec2.patch is just tweaking some configuration files, so that doesn't need to be merged and isn't really a patch anyway. There's also some new rc.d scripts which get installed and more configuration files; I'm not sure if it makes sense to bring those rc.d scripts into FreeBSD proper since they're only relevant to the EC2 environment. -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid _______________________________________________ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
