Re: FreeBSD now available on all EC2 instance types
What gave you that idea? The patches in that directory are the differences between the 9.0-RELEASE source tree and the one I used to build the AMI. Oh, must have been wishful thinking then that it might go into FreeBSD and not remain a bunch of separate patches... :) The csup'ed source tree does not contain such configuration. It does for amd64. And there's a XEN configuration for i386. But no XENHVM configuration for i386. Yep, that's why there's a patch in /root/ec2-bits which adds XENHVM. :-) Doh! Makes perfect sense. Less coffee and more actual sleep for me! :) Thanks for the clarification!

Oh, must have been wishful thinking then that it might go into FreeBSD and not remain a bunch of separate patches... :) Working on it. :-) The files rXX.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.
