#armv8 — Public Fediverse posts

Does anyone know of an inexpensive ARM aarch64 SBC that has a dedicated JTAG port? That is, one that doesn't multiplex with the SD slot and stays enabled after normal boot (or can be easily kept enabled without uboot recompile)?

Гранулярное погружение в атаки на кэш в ARMv8. Разбираем типы атак и митигации

Привет! Без лишнего: в статье расскажу про атаки на кэш-память в процессорах семейства ARMv8. Подробно изучил их для совершенствования безопасности KasperskyOS: познакомлю с теорией и практикой, механизмами работы и способами митигации. Также кратко расскажу, как мы тестировали каждый способ атаки на KasperskyOS, какие из них оказались неприменимы, какие могут представлять угрозу и как микроядро с подобными угрозами справляется. Если интересно гранулярно погрузиться в типологию атак на кэш — добро пожаловать!

#SingleBoardComputer enthusiasts experienced with booting #Radxa #RadxaZero2Pro with #Amlogic #A311D #SoC? dd the Radxa Debian #linux img to an SDCard, which does boot. The same img file does not appear to boot when dd to USB. Something special need to be done to boot from USB or SDCard? #AlpineLinux appears to have amlogic a311d2 support from https://pkgs.alpinelinux.org/contents?file=*amlogic*a311d*.dtb. It's unclear how to get the standard or uboot Alpine tar.gz files to boot. Is this something with #uboot on #armv8/#aarch64?

Сказ о том, как мы искали новые векторные расширения на ARM

Мы в Smart Engines активно занимаемся низкоуровневой оптимизацией нейронных сетей. Наши библиотеки работают на центральных процессорах, поэтому мы активно используем Single Instruction Multiple Data (SIMD) расширения. SSE, AVX и NEON уже стали привычными, но в свежих версиях архитектуры ARM были представлены новые расширения: SVE, SVE2, а также SME. Вот о них мы и поговорим в этой статье.

What’s Inside #China’s New Homegrown “#TianheXingyi” Supercomputer?
At the Supercomputing Innovation Application Conference in #Guangzhou, researchers announced a new “#Tianhe” machine called “Tianhe Xingyi”.
Reports indicate its a domestic architecture and, doubles the performance of #Tianhe2. There is no mention of accelerators, only #CPU. Likely #MT3000 based on China’s native manycore #Armv8-based #Phytium2000+ (FTP) and #Matrix2000+ (MTP) processor/node architecture
