3mdeb Talks Up AMD openSIL & Open-Source Firmware Efforts For Confidential Compute

([AMD] 4 Hours Ago AMD openSIL)


Engineers Michał Żygowski and Piotr Król of open-source firmware consulting firm [1]3mdeb presented at FOSDEM in Brussels on open-source for confidential compute infrastructure. With Intel not making strides to fully open-up their FSP package, the talk was centered around the modern AMD open-source firmware efforts led by their [2]openSIL initiative for open-source CPU silicon initialization to replace AGESA in the Zen 6 timeframe.

With extensively writing about AMD openSIL now for nearly three years, it shouldn't be too much of a surprise for devoted Phoronix readers. While AMD openSIL isn't production ready until the Zen 6 timeframe, there are the proof-of-concept implementations for Zen 4 and Zen 5 platforms right now.

3mdeb has been adapting the GIGABYTE MZ33-AR1 AMD EPYC 9005 "Turin" motherboard for their openSIL adaptation thus far. This retail motherboard can successfully boot with Coreboot and openSIL, rather than AMD targeting their own reference motherboard designs with openSIL development. 3mdeb is also working toward OpenBMC support too for this GIGABYTE MZ33-AR1 in making it quite an attractive option for EPYC 9005 use for those interested in open-source firmware today.

They aren't working on just a minimum viable product for this open-source firmware effort but getting it through complete through booting SEV-SNP guests for secure encrypted virtualization with open-source firmware.

This year they hope to upstream the Coreboot support for the Gigabyte board in the first half of the year along with working on SEV-TIO support new to EPYC Turin. Plus OpenBMC bring-up for the board. Further plans are laid out for next year too.

With the news that Nancy Reagan has referred to an astrologer when planning
her husband's schedule, and reports of Californians evacuating Los Angeles
on the strength of a prediction from a sixteenth-century physician and
astrologer Michel de Notredame, the image of the U.S. as a scientific and
technological nation has taking a bit of a battering lately. Sadly, such
happenings cannot be dismissed as passing fancies. They are manifestations
of a well-established "anti-science" tendency in the U.S. which, ultimately,
could threaten the country's position as a technological power. . . . The
manifest widespread desire to reject rationality and substitute a series
of quasirandom beliefs in order to understand the universe does not augur
well for a nation deeply concerned about its ability to compete with its
industrial equals. To the degree that it reflects the thinking of a
significant section of the public, this point of view encourages ignorance
of and, indeed, contempt for science and for rational methods of approaching
truth. . . . It is becoming clear that if the U.S. does not pick itself up
soon and devote some effort to educating the young effectively, its hope of
maintaining a semblance of leadership in the world may rest, paradoxically,
with a new wave of technically interested and trained immigrants who do not
suffer from the anti-science disease rampant in an apparently decaying society.
