It looks like my #aiagents file finally got into #qemu. Hopefully it will have some effect: https://gitlab.com/qemu-project/qemu/-/commit/3ab8a15569afa9ffd89971dff34d0636d48cae3c

I will attend the ESA Industry Space Days next week. I would be happy to meet and discuss our #RTEMS, #Linux, #NuttX, communication, #canbus, #SpaceWire, IP cores related work. Some examples
- for RTEMS CAN/CAN FD, there is near to merge Ti AM335x suport, result of this year Ning Zhang #GSoC
- motion control at #PiKRON (used by ESA for #satellite tracking and for LISA ground experiment), and at #CVUT (SaMoCon)
- for rapid prototyping CTU Simulink™ support for Linux and NuttX which can be easily extended for RTEMS and open-source pysimCoder which already target Linux, NuttX and RTEMS (ongoing preparation for Ahmad Hisham’ s thesis)
- the CTU CAN FD IP core is already available on mass produced MCU COTS silicon in addition to multiple FPGA applications including space ones
- RTEMS LwIP port started as our experiment during Premysl Houdek’s thesis and #GSoC is getting traction and was used at docking computer during Artems II mission (by the way, there will be presentation about the mission at #cvutfel by Milan Halousek at Sptember 24) and is used on TMS570 and ESP32C3 RTEMS ports
- our SumInt ADC conversion principle used in our HPLC instruments and tested at #nanoXplore for ESA which can have interesting potential for space silicon
- our NuttX support for IEEE 802.3cg 10BASE−T1S Open Alliance SPI MACPHY can be ported to RTEMS etc.
- I offer support for CAN/CAN FD emulation on #QEMU, #FlexCAN added this year
- lot of our other real-time work for Linux, NuttX and RTEMS, se my university Open Technologies Research Education and Exchange Services topics and theses lists
- we invest lot into #RISCV education at CTU, see our https://comparch.edu.cvut.cz/ pages with #QtRvSim emulator and our HDL education and sometimes even practically used cores and experiments
I arrive to Noordwijk around the lunch time on Tuesday September 15 and stay there to about 2 PM on Friday so there is lot of options to meet.

Here is another in a series of attempts to divine information from #qemu's issue tracker. I think this is showing that #AI #bugpocolypse reports tend to be verbose, a lot of sanitizer reports are probably mislabelled (quite often the agent will show the failure in a sanitized build) and having a decent test case correlates well with undeclared agent use. The "normal" size of reports for each class of device in (Untagged) for any tooling or TestCase.

The open-issue emotional roller coaster. 🎢
Hooray, there's an issue for this... oh no, it's been open since 2021! Issue affects nested #qemu virtualisation with #FreeBSD: https://gitlab.com/qemu-project/qemu/-/work_items/337

Как QEMU исполняет чужой код: изучаем Tiny Code Compilator изнутри
QEMU — это не просто виртуализация с KVM. Его главная cуперсила — способность запускать программы, скомпилированные для одной архитектуры, на совершенно другом процессоре. Безо всякой поддержки со стороны хоста. Например, запустить прошивку для ARM-микроконтроллера на x86-ноутбуке. Как это работает? Под капотом QEMU скрывается JIT-компилятор под названием TCG (Tiny Code Generator). В этой статье мы разберем его устройство на практических примерах для RISC-V и посмотрим, как инструкции превращаются из одного машинного кода в другой, как формируются блоки трансляции, и зачем там нужны longjmp и цепочки блоков.

#RISC_OS: I finally had a bit of time to upload a video with the first system boot into graphic demo for #MerlinOS It works fine on @raspberrypi 2, 3 and 4, but the video is from #QEMU which makes it easy to record both #kernel logs and Pi 2 display. Enjoy!

Transfer 2.0, или Как я перестал бояться и полюбил миграции облачных серверов
Привет, Хабр! Меня зовут Денис, я тимлид инфраструктурной Core команды в Timeweb Cloud. Итак... представьте обычную виртуальную машину клиента. Она принимает запросы, пишет в базу, держит файловый кэш, обновляет память, что-то постоянно меняет на диске. А теперь нам нужно перевезти её с одной физической ноды на другую так, чтобы клиент не заметил переезд. Звучит просто, пока не вспоминаешь, что у виртуальной машины есть память, диски, снапшоты, сетевые настройки, разные формат хранилищ, отличающиеся модели и вендоры CPU и состояния в базе управления. Любая из этих деталей может превратить задачу типа «перенести сервер» в ручную операцию с окном обслуживания, тикетом в поддержку и нервным инженером у консоли. Мы переписали модуль миграции VDS так, чтобы эти детали стали частью алгоритма, а не частью ночной операционной инструкции. В этой статье расскажу, как мы устроили живые миграции на базе libvirt, зачем оставили rsync , почему перешли на NBD для активных дисков, как выбираем RDMA или TCP, что дают SYNC_WRITES , ZEROCOPY , DETECT_ZEROES , AUTO_CONVERGE и другие флаги, и почему всё это важно не только инженерам, но и бизнесу. Кодовые фрагменты взяты из реального модуля управляющего трансферами. Они немного сокращены и упрощены для статьи, но отражают настоящую логику. В целом материал будет полезен как сетевым инженерам, так и пользователям, для понимания всех внутренних процессов — что и как устроено и почему работает так, как работает.

So … while this is obviously nice for virtualized gaming, what about video decode/encode acceleration?
Is there a way to give a #Linux guest access to the host #GPU's video codec acceleration without GPU passthrough?
Just like it's possible to pass /dev/dri into a container, can I do a similar thing with a #QEMU / #KVM virtual machine?
