 Perfect, then all that remains is to wait for the update to Fedora 40. But what procedure should be used to install it?  Do we need new repositories to install?

Rejoice! Chromium is also now available for Fedora 40! It takes years to get to this stage. Now we could all relax :D

Firmware / Re: Firmware 2.10 for Talos-II and Blackbird available

what is the linux kernel version of firmware 2.10? Some cards are known to be buggy with old kernel, please refer to https://wiki.raptorcs.com/wiki/POWER9_Hardware_Compatibility_List/PCIe_Devices for compatability

6.6 I think. The new firmware is up and running on my evaluation system but I'm not loading firmwares as r34per is trying to do.

I've heard the same too, that it's had it since Vega -- but that it needs PSP or ME on the CPU side too to be effective.

Do you know where I might find literature on this? In what way does it attempt to link to the CPU PSP?

It seems to have fallen through with no change brought about by any of the dialogue.

Their gitlab repo has more recent changes so I'm guessing that's where the 2.10 version is.

Firmware / Re: Updating Talos II firmware to IBM PNOR V2.18?
« Last post by tle on March 21, 2024, 09:21:33 pm »
The 18c & 22c parts are "paired" meaning 2 SMT4 cores share the same L2 & L3, unlike the 4c and 8c which are "unpaired" meaning each core gets the full L2 and L3 to itself.    This is not the same as "fused" (i.e. SMT8 cores) but it is quite likely that the fix will also work for "paired" cores as presumably the issue is sharing cacheable/non-cacheable pathways.   Good luck!

I think you're right about the terminology, but yeah, I doubt the IBM docs draw a distinction since those docs are exclusively written for SMT8 users.

I've successfully built a PNOR with IBM's patch; it installed without major issues (I accidentally hosed things the first time I installed it due to the BMC running out of RAM -- protip, don't put multiple PNOR images in OpenBMC /tmp/ -- but power-cycling the BMC fixed that). So far it seems stable, I'll be running it for the next month or so to see if any checkstops happen.

Would you be able to provide more details on which patch? Many thanks

This is the hcode branch I used: https://github.com/JeremyRand/hcode/tree/talos-2019-07-25-master-rebased

As you can see, it's simply a copy of Raptor's hcode, rebased against current upstream IBM hcode (there were no rebase conflicts). The specific bugfix commit is this one: https://github.com/JeremyRand/hcode/commit/ca06a0c996e3b48c02cfb3912dddf7ca23ec4202

I've been running it on my DD2.3 2x18-core Talos II for 2 months, and my DD2.2 2x22-core Talos II for 1 month, and I have had no checkstops on either since applying the patch, nor any new issues. At this point I can recommend that Raptor integrate the bugfix into a new PNOR release. Since the rebase had no conflicts, it should be trivially easy for Raptor to do this.

Thanks for the information

Folks, any idea where could I find 2.10 changes in git repo?

I was looking into https://git.raptorcs.com/git/ but unable to find any changes in blackbird-* that are related

I dunno about their motives, but even just from a performance standpoint, I imagine they have a point. AMD's own software is really bad, and I can't help but imagine their firmware could be improved upon too. Plus, being able to actually see what goes on in there is nice.
