Two pushes, two heads-up messages... been a busy week
By jmcp-Oracle on Sep 19, 2008
I've had a busy week. Apart from getting my ducks in a row for a backport of Pluggable fwflash(1m) and my redesign + reimplementation of stmsboot(1m) to a Solaris 10 Update, I also pushed two rather interesting changesets into builds 99 and 100:
- arcmsr(7d), the Areca SAS/SATA RAID card driver (build 99), and
- ITU construction utilities (build 100).
Why are these important? First off, the arcmsr(7d) driver is the first storage driver that we've integrated as a result of an RFE coming in via http://bugs.opensolaris.org.
Normally we'd go through months of legal back-n-forth getting licensing arranged and back-to-back support agreements with SLAs... a big undertaking. After the rfe was filed (by the CEO of Areca Technologies as it happens), the arcmsr(7d) code went through Sun's Open Source Review process (it's BSD-licensed), and then it was a matter of getting the code to compile within the existing ON driver.
The second reason this is important is because our group (Solaris Storage drivers) now has a much better idea about how to get this sort of integration to actually happen. One thing that people always complain about is that $OtherOSen always have better (more wide-ranging) driver support than OpenSolaris, so now we've got a better idea about what to do, I hope we'll be able to make getting drivers integrated more easily.
Thirdly, the ITU construction utilities supersede the existing SUNWpkgd tools - which are old, enforced an arbitrary breakdown between 32- and 64-bit packages, and were pretty darned useless for patching boot and installation media when it comes to Grub. With the code which I integrated on Wednesday morning (yay first heads-up message for the build!) those restrictions now no longer apply - making the task of, oh, I dunno.... testing installation of OpenSolaris to volumes in a new RAID card (to pull an example out of thin air)... much easier. We're all winning with this.
I would like to publicly thank Billion Wu and Erich Chen of Areca Technologies for their assistance (and patience!) with getting arcmsr(7d) integrated.
I would also like to thank Jongki Suwandi who wrote the initial version of the ITU construction tools, and Jan Setje-Eilers for passing them on to me.
