Posted Apr 13, 4: The music fan in me is mildly disappointed, however, that they didn’t call the project “Run-BMC”. I have a server km away whose BMC is hung and cannot be restarted even with a hard reboot command from ipmitool. The system uses the U-Boot bootloader and an embedded Linux distribution created with Yocto. I said ‘I’d prefer to have BMC’s with simpler capabilities to ensure robust response times’ which needs anyone reading to infer that not running eBPF programs in full-Linux or having a simpler capabilities means a dedicated RT kernel is necessary to ensure robust response times.

Posted Apr 13, 0: But BMCs almost invariably ship with a proprietary IPMI implementation in binary-blob form though, in most cases, that blob is running on Linuxwhich is limited in functionality to what the vendor chooses. We have rewritten the ASpeed SoC kernel pretty much from scratch and cleaned up a bunch of the drivers, made it device-tree based etc Please consider signing up for a subscription and helping to keep LWN publishing.
Without subscribers, LWN would simply not exist. Once the BMC has been compromised, the attacker has direct access to essentially every part of the server.
From the audience, Grant Likely mentioned that Linaro would like to see patches, to which Fang replied that the OpenBMC team is interested, but that it does not consider most of the code to be in a ready-to-upstream, fully working state.
We can only go by what aseped wrote, which seemed to be a presumption that RT was needed for “robust response times”, so the response was both to correct this apparent misconception for you sapeed for everyone aspefd reading along.
The system uses the U-Boot bootloader and an embedded Linux distribution created with Yocto. Posted Apr 13, 6: The next step is open software to interface with OpenBMC to do things like rack-level power management. It may only be a start, and only support one BMC vendor, but that itself is still noteworthy progress in comparison to the unappealing security and software-freedom issues that plague so many systems via the IPMI framework.
I have a qspeed km away whose BMC is hung and cannot be restarted even with a hard reboot command from ipmitool. Fang cited two issues as the focus of current OpenBMC development. I’m going to have to power that sucker down by physically unplugging the power cords and hope the BMC comes back, and Linkx can’t do that until I schedule a visit to the data centre.
He also said that Facebook has started work on a BMC development board that will hopefully serve as a low-cost entry point for interested developers.

You can have crap response with or without RT, and you can have good response with or without RT. Posted Apr 15, The Yocto build includes three layers.
Furthermore, as Matthew Garrett outlined quite memorably at linux. Posted Apr 14, Usually we think this is a net positive but I’m not always so sure, I’ve seen plenty attempts at HA actually cause more outages than they ever prevented, and one of the goals of IPMI is to increase service uptime by allowing you to reboot servers quickly when the OS fails. The BMC is connected to most of the standard buses on the motherboard, so it can monitor temperature and fan sensors, storage devices and expansion cards, and even access the network through its own virtual network interface that includes a separate MAC linuc.
OpenBMC, a distribution for baseboard management controllers
On top of that comes a general BMC layer that enables the bootloader, C library, and kernel recipes for a particular SoC vendor at present, meta-aspeed.
OpenBMC, a distribution for baseboard management controllers. Libpal is a network-packet assembly library; Facebook uses it to generate a small set of IPMI messages to provide compatibility with other monitoring lniux. But what of those times when you’ve gotta dust up and nuke from orbit.?
Response times are more a matter of good engineering of the userspace apps. This behaviour is unwelcome — and your forceful response probably means you’ve suffered in learning this knowledge, so I’m sorry to hear your pain but: What a world where BMC’s aren’t a security threat on nearly every system. I said ‘I’d prefer to have BMC’s with simpler capabilities to ensure robust response times’ which needs anyone reading to infer that not running linu programs in full-Linux or having a simpler capabilities means a dedicated RT kernel is necessary to ensure robust response times.
You barely contributed to the discussion.
