General CPU Discussion / Re: 3U HSF End of Life'd

« Last post by Hasturtium on October 04, 2024, 08:46:11 am »

If anyone is desparate for heatsinks, I understand power8 heatsinks are physically compatible.  There are usually some on ebay in various heights.  Some part numbers may be 00RR234, 00RR232, 00E8918, 01KL499.  I think the 3u with fan was only used by Raptor, so there probably aren't many out there.  3D printing a fan shroud is probably not too hard.

Some news would be nice, but I'll admit I'm feeling a little pessimistic.

That is news people can use, and it should probably go onto the wiki. I'm with vikings.thum - I love my Blackbird, but the lack of news while prices on existing products rise and components as foundational as 3U heatsinks are delisted feels a smidge like watching the water rise during a bad storm.

Hopefully this is a sign S1 is coming out quickly[..]

The "talk is cheap" thing they've got going is kind of nice, until it's not any more. Maintaining a joyful anticipation for Talos III/Blackbird II/S1 systems with no news whatsoever for more than 11 months (with the announced release date ending in less than two months) is probably not something people are going to do.

I'll admit I'm excited for whatever they're doing with S1, as it is now Q4 2024. But life has taught me not to work up expectations.

Hopefully this is a sign S1 is coming out quickly, presumably with its own cooler.

General CPU Discussion / 3U HSF End of Life'd

Raptor's page has de-listed the 3U heatsink due to it being discontinued. Has the situation with the modified bracket to accommodate x86 heatsinks gotten to a point where they could offer those in their place? Feels like Raptor's in an increasingly awkward place.

Firmware / Re: Updating PNOR/BMC firmware on talos II Lite

« Last post by ClassicHasClass on September 30, 2024, 10:30:33 pm »

You probably should be running the most current firmware anyway; there are other improvements. You don't need to update the FPGA, just the PNOR to get Petitboot up to date.

Applications and Porting / [DEV] Binsider is a nice analysis tool ELF binaries

« Last post by tle on September 30, 2024, 08:54:17 pm »

This tool is quite useful IMHO for developers who want to peek inside the ELV binaries to find bugs or simply to reverse the application logic.

Mod Zone / Re: Custom cooler mount

« Last post by Woof on September 30, 2024, 04:20:05 am »

It's complicated...! I initially designed for any AM5, but as I started testing, and having put a cooler mounting screw into my motherboard (because they're too long) I changed the design.

For the first change I made a thicker bracket, which fixed the screws going into the mobo but needed a copper shim (a 'hat') for the CPU. I tested this for a while but was never happy with it: the design worked but the copper part was difficult to get produced to the required accuracy, so wasn't anything anyone else was going to get made (it took a lot of attempts, and quotes from some machining companies were thousands for a one-off).

Eventually I opted for custom mounting posts for the cooler, adopting the AM5 bolt pattern but replacing the cooler's fittings completely, and since I no longer used the cooler's own screws I changed the pitch for something more appropriate, losing compatibility with any AM5 cooler.

Short version: it works with any SecuFirm2 Noctua air cooler, as long as the cold plate is large enough, tested with a U12S (which works perfectly); for water cooling an EK-Pro AM5 water block fits, anything else hasn't been tested. Both these solutions have large cold plates that correctly cover the POWER9.

A lot of text... all that said, I have a pile of spares and test parts, most of which will fit any AM5 cooler, along with the custom copper part to adapt any cold plate. PM me, I've been offering to send these to anyone who asks, they're only getting recycled otherwise.

Firmware / Idenitfy versions of firmwares

« Last post by mparnaudeau on September 30, 2024, 02:35:22 am »

I want to update the firmware of my Talos 2 because the machine is really noisy, with fans are permanently running high (ipmitools shows 2 fans at 8800-8900 RPM) ... and I saw that there was changes (a fix) in firmwares 1.0x.

I would like to know the current version of the low-level elements (BMC, firmware ...). I only found the tool lsmcode (from the package lsvpd) that displays a list of elements with their git hash:

Version of System Firmware : 
Product Name          : OpenPOWER Firmware
Product Version       : talos-v1.20-161-g76f78f4
Product Extra         :        skiboot-bc106a0
Product Extra         :        occ-a8d0767
Product Extra         :        hostboot-884b60b
Product Extra         :        buildroot-2017.11.2-8-g4b6188e0f2
Product Extra         :        machine-xml-221192a
Product Extra         :        sbe-a389a5d
Product Extra         :        petitboot-v1.7.1-p836d356
Product Extra         :        linux-v4.15.9-openpower1-p9e03417

In the page that lists the different update files https://wiki.raptorcs.com/wiki/Talos_II/Firmware, archiives for BMC, PNOR and FPGA have an associated hash but I can't make them match with anything that I know.

So, are there other solutions to get the version of these elements?

I access BMC with ssh (using the web interface, it refuses to get even a login page): it is possible to get its version and possibly the firmware version from there?

Before upgrading, I just would like to know from where I start.

Please give me some advices: Maybe you will think that I can only update the firmware directly to the latest version (v2.10) whatever are the current element versions ...
