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!

@cas @wolf480pl granted, the distain is mutual, given almost all #SBC & #SoC vendors refuse to do basic #documentation on how their shit works and barely release some dodgy images with custom kernel modules.
- @olimex and #RaspberryPi being an exception of the norm, but #Rockchip, #Allwinner and other SOCs are a real pain in the ass to support unless they are #ARMv8 with #UEFI to boot.
#Apple's Hardware does have @AsahiLinux as project to care for and is popular enough to be worth the hassle for them, as it brings decent performance and battery runtime to the table...
The #MAME team has blessed us with version #0.276, crammed with "emulation goodness" that no one asked for. 🤡 Remember that obscure 64-bit #ARMv8 recompiler? Neither do we, but apparently, it's a big deal. 🧐

#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.

@lamp yes and no.
Yes, #Apple will #EoL the #Intel-based "Cheesegrater" #MacPro by 2029-2030 as per their preannounced platform lifecycle of 10 years.
No, because #Apple's #ARMv8.1-A - based #SoC's are heavily modified in that they require a feckton of custom chips solely for the purpose of #ReducedLifecycle and making repairs harder if not impossible to facilitate...
Unlike their #amd64 / #EM64T - predecessors they don't have a dedicaded #EFI chip with "#BridgeOS" aka. #AEFI aka. #macOS - #Recovery on but use the exact same #Flash chips that are #RAID0 as #SSD, and since those are custom with their own controllers ( based off info from @marcan ) - basically every chip is it's own NVMe but proprietary...
And when (not if) they (inevitably) die (due to exceeding TBW lifecycle or terrible engineering frying them with 12V on a 2,7V rail ), the entire system is braindead.
And that is not by accident but rather intentional...
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
