We're honoured to be able to support @_everythingopen again this year, and of course, to be attending too! 🎉 Looking forward to a great conf. Come and say hi!
#EverythingOpen 2025 would not be possible without Royal Penguin sponsor: @CodeConstruct provides high-quality #openSource software services. Visit: codeconstruct.com.au Program: 2025.everythingopen.au/schedule/ Tickets: 2025.everythingopen.au/attend/tickets/ #EO2025 #conference
Today's #EverythingOpen retro goes #OpenHardware - it's @jeremymeep of @CodeConstruct and the #LibreBMC baseboard management controller, used to power the @IBM #AC922 #WitherSpoon. If you love #OpenPOWER, #FPGA, #HPC or #CPU, this one's for you. 🎥 youtube.com/watch?v=OLoKQ1…
Code Construct developer @mramboar has just published a new article around dealing with #git source trees when coordinating with an ever-changing upstream. Check it out at: codeconstruct.com.au/docs/bisect-in…
It's a pleasure! Thank you, #everythingopen team!
A huge thank you to Adelie Penguin #sponsor @CodeConstruct and to Fairy Penguin #sponsor @Collabora for your support - we couldn't deliver #EverythingOpen without you! 2023.everythingopen.au/sponsors/
Come and check out a bit of our #librebmc shenanigans at #EverythingOpen
Continuing our Speaker Spotlights as we slide in to #EverythingOpen, please meet Jeremy Kerr of @CodeConstruct, who will be presenting "#LibreBMC: literally everything is open". As Jeremy explains, the #hardware, #firmware and implementation is all #open. 2023.everythingopen.au/schedule/prese…
🫡🎺
Tonight, @PawseyCentre's switches off Magnus after eight years of service to the Australian science & research community 😢 Magnus' impact has been immense for the acceleration of science and research in Australia 👏🏽 pawsey.org.au/case-studies So long, and thanks for all the fish.
... we also have some work in progress for decoding this directly "off the wire" through a mash-up of sigrok, any sigrok-supported logic analyser hardware, and your i2c bus. Stay tuned for updates!
Debugging MCTP communications? A few MCTP-related protocol decoders have now landed in upstream wireshark: · MCTP · MCTP control protocol · NVMe-MI You'll need bleeding-edge wireshark for now (as of gitlab.com/wireshark/wire…), but these should all be included the next release.
We have been on a document-writing frenzy this week! Here's the latest: the details on updating NVMe device firmware over the out-of-band MCTP link, using the NVMe-MI code we have been working on. codeconstruct.com.au/docs/nvme-mi-f…
(this is also a contender for the lowest-cost 64-bit powerpc machine, just with some assembly required. Unlike most other ppc64 hardware, doesn't require a two-person lift 😆 )
@mikeyneuling ... if you're looking to dive in to open hardware on a technical level, the OrangeCrab running Microwatt is a great way to get started, for under $200. We have a guide to getting it running at codeconstruct.com.au/docs/microwatt…
A great background from @mikeyneuling on our recent #libreBMC work, and how it relates to the progression of hardware into the open source space
#LibreBMC shows the amazing things that can be done now with open hardware. Microwatt running Linux + OpenBMC powering up a server class machine.
Code Construct has been working on an exciting project with @OpenPOWERorg : We built a fully open source Baseboard Management Controller (BMC) implementation — right down to the hardware — and used it to boot & manage an IBM AC922 server. Full details at: codeconstruct.com.au/docs/dcscm-ope…
#LibreBMC shows the amazing things that can be done now with open hardware. Microwatt running Linux + OpenBMC powering up a server class machine.
More documentation! 📄We have just posted an overview of our recent additions to libnvme, enabling Management Interface (MI) communications with NVMe storage hardware. Read all about it at codeconstruct.com.au/docs/nvme-mi-w…
Our patches for NVMe-MI support have just landed in the upstream libnvme project! 🥳 github.com/linux-nvme/lib… These provide base support for managing NVMe devices using a i2c/SMBus link. There's an example program, mi-mctp, included too. More protocol functions coming soon…
We're back on to some MCTP + NVMe-MI development - so a bit of dev hardware: an AST2500 EVB, serial console + netboot, EVB's i2c bus connected to our own NVMe break-out board, hosting a MCTP-capable NVMe drive, with outputs to a @dangerousproto Bus Pirate for i2c tracing. 🥳
This means that the 5.18 merge window is open - we have the next MCTP transport driver queued for this next version: MCTP over I2C/SMBus. This will allow MCTP communication with a wider set of peripheral devices - like PCIe devices, NVMe-MI endpoints, network hardware and more.
Linux kernel 5.17 has been released! We have a few updates for the MCTP stack that have landed: • The first MCTP transport binding is now available: MCTP over Serial. • Netlink events are generated on local MCTP addresses add/remove • … plus some small fixes and cleanups
@mikeyneuling @OpenPOWERorg @GregDavill ... and we've just posted a little documentation on getting started with Microwatt on the OrangeCrab, if you'd like to start experimenting yourself!
Just posted: a quick guide to getting the Microwatt core running Linux on an OrangeCrab ECP-5 FPGA: codeconstruct.com.au/docs/microwatt… This gives us a reasonably easy and inexpensive way to start developing with an #OpenPOWER core, using entirely open source tools. 🎉
