#qemu — Public Fediverse posts

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.

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.

Anyone having a working #QEMU config for booting an old Windows XP?

It appears that "pc-q35-2.10" is no longer available. And with "pc-q35-10.1" it fails to boot with an error stating that the system isn't fully ACPI compliant.

Edit: Same for "pc-q35-4.2" which is the oldest one I can select.

Edit: This is my config right now (worked with "pc-q35-2.10"): https://privatebin.net/?149dc6d610a02133#Ff49yRgAuEtAoNRyFpXMgsw4yT89q4CZYydu2ksTvPSw

Any Tipps?
Using qemu, bcause my corporate host is horribly restricted and changing net adapters is impossible. So I'm forced to usermode networking. Basically user network works. I'm using it for local software dev. Problem is its slowness.
Any idea/doc how to migrate slirp to passt for (hopefully) usable network performance? Current args:

#aarch64 builds of @binjr are coming, and I have proof!

But the amusing fact(*) about that screenshot, is that it shows an aarch64 Linux Java Virtual Machine running on an x64 Windows host and ultimately rendering in a native window on the host's desktop.
It's not very fast, obviously, but given the amount of layers it has to go through, it is kind of mind blowing that it actually works pretty much seamlessly:
Windows 11 ➡️ WSL ➡️ Debian bookworm ➡️ qemu ➡️ OpenJDK-24 JVM ➡️ JavaFX ➡️ GTK3 ➡️ X11 ➡️ RemoteDesktop ➡️ GDI ➡️ Windows.

And why would you want to do that, I hear you ask? Well, that's the neat part: you don't! (Seriously it's pretty daft. Don't do that).

(*) It has been brought to my attention before that my personal notion of what constitutes an "amusing fact" isn't wildly shared amongst the general public. You have been warned.

A picture tells more than 1000 words: I have now GDB debug support for my own x64-based OS! GDB just attaches to qemu that runs my OS, and provides me C-based source level debugging functionalities! :-) #x64 #debugging #qemu #gdb #osdev #osdev #computerscience

Antes de começar... A ideia inicial para o vídeo era ensinar como compilar a versão atual do Gnome Boxes, pois o repositório do Pop!_OS 22.04 oferece a versão 42...

LINUX + FL Studio + платные VST (32+64)

Я смог запустить FL Studio и любые VST плагины в GNU Linux, при этом экранировав всё это дело от основной системы! Теперь я могу безопасно писать музыку, играть на гитаре с крутыми эффектами и крутить баст-бустед звуки друзьям в Дискорд и Телеграм. Хотите так же , но не проходя через ту боль и не теряя столько же нервов, сколько потерял я ? Установить FL Studio на Linux

I just wrote a #blog post detailing my adventures with the Icon #Linux #PDA and the attempts to #emulate it with #QEMU.
Sorry for not formatting the command-line blocks properly, I wasn't sure how to do it in Markdown and then the Pandoc + Wordpress formatter combination messed it up even more so I had to stitch it up together my self.
I really need to find some #Wordpress #Markdown plugin.
Let me know what you think!

Some claim #SLIRP has poor performance. Would be interesting to do some kind of benchmark.
