Recently, we merged into the op-build project (the build scripts for OpenPOWER Firmware) a defconfig for building OPAL for (certain) POWER9 simulators. I won’t bother linking over to articles on the POWER9 chip or schedule (there’s search engines for…

Contributions to the kernel for the ASpeed BMC processor used in OpenPOWER systems (including Barreleye) made by the IBM OpenPOWER/OpenBMC team.

Upstream kernels on BMCs isn't a pipe dream anymore.

Good details on live patching for the ppc64le architecture from the PowerPC kernel maintainer, +Michael Ellerman​
As part of the 4.6 and 4.7 development cycles, several of us from IBM & SUSE finally got all the pieces lined up to enable kernel live patching for ppc64le. If you're not familiar with kernel live patching, there's a pretty good write-up at Wikipedia. But the basic idea is that you can, ...

Wanna know what's happening in PowerPC Linux kernel land? +Michael Ellerman wrote a really great summary in his pull request for the v4.7 merge window. Be sure the checkout the new POWER9 bits, especially the new Radix MMU code from +Aneesh Kumar.

What is SROP??? Sigreturn Oriented Programming – a general technique that can be used as an exploit, or as a backdoor to exploit another vulnerability. Okay, but what is it?? Yeah̷…

very good, I just saw an OpenBSD discussion exactly about it (https://marc.info/?l=openbsd-tech&m=146281531025185&w=2).

Less than a year ago I read a lot about signals and how Linux implements it, I saw everything in details but SROP didn't even get close to my mind. Need to improve my skills on security. :D

Thanks for sharing.

Thanks for the excellent blog on the technology, +Breno Leitao!
Ubuntu created an interesting way of distributing binaries called snap, and the snap tool is available in Power since Ubuntu 16.04. Snap is a way to make packages available with their dependencies …

Updated my thoughts on #PowerLinux little endian for those who still have questions and/or want an update...
by Jeff Scheel, IBM Distinguished Engineer, Linux Technical Strategy Two years ago this month, I published my first blog about the Linux on Power strategic shift from big endian to little endian, titled Just the FAQs about Little Endian , and I still get questions about it today. So, I figured it was time to make updates. The questions listed below are either updated or new. If you do not see your particular question, please read the original doc...

Interested in Device Tree information, then you might want to join the devicetree-spec@vger.kernel.org mailing list. Work has begun to revive the document.

In the future, #OpenPOWER will be providing a document with extensions used on Power Systems, but this document clearly fills a need as a building block.
Hi all, I've cut the first formal release of the devicetree specification. This is the baseline release with a bunch of editorial fixes from the v0.1-pre1 release from a few weeks ago. Now begins the task of bringing new bindings into the spec. You can find the released document here: ...

In what is likely to be a series on how firmware makes some normal tools harder to use, first I’m going to look at american fuzzy lop – a tool for fuzz testing that if you’re not using then you most certainly have bugs it’ll find for you. I first got…

I just merged in some base POWER9 support patches into skiboot. While this is in no way near complete or really enough to be interesting to anyone that isn’t heavily involved in POWER9 development, it’s nice to take upstream first and open source first so…

Happy to see #PowerLinux support in DRBD. Give it try!!!
 
DRBD 9.0.2 just dropped, less than 1 week prior to OpenStack Summit. Coincidence? I think not! Learn more here: www.drbd.org
High availability is a crucial factor in today's world of business. With our revolutionary DRBD replication technology and a clearly defined service offering, we make your life a whole lot easier.
