HabrBareMetal 2.0: разбираемся, какие GPU выбратьНедавно мы обновили BareMetal 2.0 в составе нашего «Публичного облака». Теперь в инфраструктуре есть выделенные физические серверы с высокопроизводительными GPU-картами. Они позволяют работать с задачами, где критична скорость вычислений. Расскажем, что именно изменилось и какие задачи можно теперь решать быстрее.<a href="https://habr.com/ru/companies/rt-dc/articles/889560/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://habr.com/ru/companies/rt-dc/articles/889560/</a><a href="https://zhub.link/tags/gpu" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gpu</a> <a href="https://zhub.link/tags/baremetal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#baremetal</a> <a href="https://zhub.link/tags/%D1%80%D1%82%D0%BA%D1%86%D0%BE%D0%B4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#рткцод</a> <a href="https://zhub.link/tags/%D0%B3%D0%B8%D0%B1%D1%80%D0%B8%D0%B4%D0%BD%D0%BE%D0%B5_%D0%BE%D0%B1%D0%BB%D0%B0%D0%BA%D0%BE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#гибридное_облако</a>

I've not done kernel code (yet) in Rus. Instead I've worked on two bytecode (with JIT) hosts, i.e. Enarx (wasm) and now with PolkaVM (previously wasm but I'm working on riscv32emac derivative which is the next generation). And right, I'm implemented a crate for zmodem (see zmodem2) ;-) The crate that I'm not yet sure because have not been able to do yet stuff that I'd want to do with it is: <a href="https://github.com/rust-vmm/vm-memory" rel="nofollow noopener noreferrer" target="_blank">https://github.com/rust-vmm/vm-memory</a> I.e. use it for special mapping but with no VMM involved (my uses cases actually involve both with and without VM containers). So looking into that over time. E.g. Paolo is involved with this so I expect it to be quality, and rather contribute than look for other option. <a class="hashtag" href="https://social.kernel.org/tag/rust" rel="nofollow noopener noreferrer" target="_blank">#rust</a> <a class="hashtag" href="https://social.kernel.org/tag/rustlang" rel="nofollow noopener noreferrer" target="_blank">#rustlang</a> <a class="hashtag" href="https://social.kernel.org/tag/baremetal" rel="nofollow noopener noreferrer" target="_blank">#baremetal</a>

HabrРазыменовываем NULL на RISC-V ядре scr1Во время работы в ASIC дизайн центре я потратил немало времени на отладку ошибок и падений ядра, просматривая временные диаграммы на шинах AXI от процессора к памяти. Иногда оказывалось, что адрес чтения из памяти оказывался 0x00000000 - классический случай разыменования нулевого указателя в C. На системах с ОС это приводит к известному всем C программистам segfault-у. И в bare metal системах разыменование NULL может приводить к интересным ситуациям. В этой статье рассмотрим, что происходит при разыменовании NULL , используя для пример open source RISC-V ядро scr1 и open source инструмент симуляции RTL Verilator.<a href="https://habr.com/ru/articles/851188/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://habr.com/ru/articles/851188/</a><a href="https://zhub.link/tags/microcontrollers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#microcontrollers</a> <a href="https://zhub.link/tags/undefined_behaviour" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#undefined_behaviour</a> <a href="https://zhub.link/tags/verilog" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#verilog</a> <a href="https://zhub.link/tags/baremetal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#baremetal</a> <a href="https://zhub.link/tags/riscv" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#riscv</a>
