Solaris 10 8/11 KUP

The first sustaining kernel patch for Solaris 10 8/11 (update 10) is now available: 147440-01. But Solaris 8/11 is yet to be released, they could be waiting until Oracle world for the release or they are having trouble with the release. The patch does not contain many changes but another interesting patch that requires the update 10 kernel patch was also just released:

147159-01: T4 crypto performance patch
7030953: AES CBC mode code path spends 50% time in non-encryption operations
7032670: AES-128-ECB 16KB encryption on T4 can be significantly better
7032698: AES-128-CFB128 16KB encryption (via ucrypto API) on T4 can be significantly better
7033814: assertion failure in OpenSSL speed RSA-4096 test via pkcs11 engine on T4
7036405: heavy mutex contention in libumem results in negative scaling of multi-threaded RSA test
7048794: 64-bit libsoftcrypto not enabled for T4
This is is the second proof that Solaris 10 will indeed support the new SPARC T4 processor.

Update: The final release of Solaris 10 8/11 have the the first sustaining kernel patch already installed (147440-01/147441-01).

I'm thinking it's "wait for the conference" rather than actual problems. The PowerPath issue might have helped though.

Thanks for the information about the U10 sustaining KJP, that's interesting stuff.

So what do you think about the Solaris 11 Early Adopter release? I'm still trying to find a list of new features, but the release notes are still for 2010.11.

What I really want to know is what the "killer feature" that Joerg often mentioned might be... =-)

It's been many months since I saw anything new for the S11 release. Beside fuse, NFS in zones, ZFS hybrid allocator and support for the SPARC T4 it's hard to say. I hope I will get some more information at Oracle World.

Interesting with a new "killer feature", especially one that has been implemented in just a year, maybe we'll see DTrace probes for Oracle RDBMS or BP rewrite:)

Sorry if I was unclear. I meant the just-released, supposedly "feature complete" preview of 5.11 based upon build 173.

See: also there are some Twitter posts.

There are new docs (1.5GB worth), but the "what's new" release notes are left over from 2010.11.

It would seem that the killer feature has yet to reveal itself. I'd love to see BP Rewrite, but that's not my first guess.

Supposedly this new feature is why they had to cut off US-IV+ and earlier models... but of course that could just be the marketing treadmill.
