Check out what using a 40-core (160 thread) #TalosII with optional #AMD WX7100 GPU looks like! Screenshot of actual system showing Firefox, Blender, and htop under #KDE Plasma 5 on #Debian .

We're tracking information on Spectre and Meltdown here:
https://wiki.raptorcs.com/wiki/Speculative_Execution_Vulnerabilities_of_2018
As far as future updates are concerned, firmware patches for OpenPOWER systems will be posted to the official IBM OpenPOWER GitHub repositories, and also to our repositories as soon as the patches are integrated into our firmware stack.

While you are correct that there is a pattern of steppings, this is entirely coincidental and reflects additional steppings that were required for POWER8E, and then even more that were needed for POWER9.
Preproduction samples of POWER9 are generally DD1.2 (now unsupported by firmware), DD2.01 (second prototype pass, supported but with serious defects), and DD2.1 (almost fully functional but with defects requiring another stepping). DD2.1 is what we're basing our no performance loss comparison against.

#AMD currently indicating RCE not possible on #PSP with this exploit. Waiting for public verification outside AMD before sounding the all-clear; we believe the fundamental design of #AMD systems with the #PSP continues to be a security and integrity risk.
-
Recent #AMD #PSP exploit may also open door to transparently defeating #SME (encrypted virtual memory). The #PSP manages the #SME encryption key according to #AMD documents https://social.raptorengineering.io/url/390
-
#AMD highly privileged #PSP vulnerable to attack, with full control of the PSP environment possible via PC manipulation. The PSP has FULL access to the entire system memory space; this theoretically allows undetectable #rootkits on ALL #AMD platforms. http://seclists.org/fulldisclosure/2018/Jan/12

Yes, we are aware of IBM's lack of information on that page. We are disclosing some of the details of the issue to keep our security-conscious customers informed.
In a nutshell, only the DD2.2 silicon changes were needed. DD2.2 silicon is able to close off these security holes, with the exception of the Spectre same-process read vulnerability that affects the entire CPU industry, with only changes to firmware and a small kernel change. Note that the kernel change is minimally invasive and is not related to the 30% performance loss Intel KPTI mitigation.
-
#POWER8 and prerelease variants of #POWER9 vulnerable to #Meltdown (CVE-2017-5754) and #Spectre (CVE-2017-5753 / CVE-2017-5715). #POWER9 is being patched and will not be vulnerable at ship, and there will be no performance loss versus current #POWER9 samples. Patches coming soon.

And this is a good example of why @RaptorCompSys has chosen to offer open-friendly #AMD GPUs as first-class citizens for #TalosII , versus closed and locked #NVIDIA https://www.theregister.co.uk/2018/01/03/nvidia_server_gpus/ … via @theregister
-
Feeling the heat yet? #OpenPOWER is completely transparent and security hardened, switch to a vendor that doesn't hide critical flaws for decades with the #POWER9 #TalosII from @RaptorCompSys !

We're working on the firmware to add new features not seen in other OpenPOWER systems. We'll let everyone know what those are once the systems near ship!
-
Update from @RaptorCompSys:
"PRODUCTION UPDATE: Today we learned that a key supplier was unable to meet their commit date. Initial shipments are delayed until late January / February as a result. Q4 orders will ship first, then Q1. We'll be using this time to make #TALOSII even better!"
-
"Neutering" the ME won't help avoid complete ME-based compromise of Intel machines: http://www.theregister.co.uk/2017/11/09/chipzilla_come_closer_closer_listen_dump_ime/
Time to switch to #TalosII and #OpenPOWER !

Ever wonder just what's under that silver heatsink? Check out photos of the Microsemi SAS controller from the most recent prototypes! https://social.raptorengineering.io/attachment/375

Very glad to hear it! We're trying to make sure that libre-friendly, owner-controllable tools are available for all applications, and #IntegriCloud is our answer for the cloud systems / IaaS market.
-
This depends mainly on the success of efforts like the Talos™ II. If we see significant update of the POWER platform through machines like Talos™ II then we definitely have plans to expand into the desktop market, and from there possibly the laptop market as well.
As you can imagine, building a new ecosystem around secure computers and a relatively newly supported architecture takes time, but we're definitely up to the challenge and working toward these goals as quickly as possible!
-
Manufacturing of #TalosII PCBs and related hardware proceeding on schedule. It's not too late to purchase a secure Talos II for Q1 ship!
-
#TalosII dual CPU fan noise under 55dB@1m w/ full load, drops below 45dB in typical metal chassis. Idle noise even lower - ears quite safe!
