Odd: if I send a TCP "MSS=600"-option to a Linux virtual machine, the option is ignored (by the system (with apache)) unless I disable tcp offloading!

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.

Запуск Vivado 2019.1 на Orange Pi 3 LTS через QEMU
Если вам интересно как выглядит работа Vivado на одноядерном ARM процессоре с частотой 1.8 ГГц, и 2 Гб ОЗУ, то я вам это покажу, и расскажу, как я запустил и успешно прошил плату (ДА! Собрал проект и прошил).

Hype for the Future 137D → What to Expect from Virtualization Videos
Introduction When novaTopFlex creates videos involving the presence of virtual machines, expect the display resolution of the display to be recorded using the ffmpeg command to be set to 960x540. The ffmpeg command-line parameters should be set as follows: ffmpeg -f pulse -i default -f x11grab -framerate 60 -draw_mouse 0 -i .mp4 Virtualization Standards More information will be available directly within the video comments at https://www.youtube.com/@novaTopFlex. -

Собираем Linux, который весит меньше, чем мем с котиком, ну или почти…
Мне всегда было интересно, насколько минимальным может быть Linux. Три года назад я уже публиковал статью , но понимание темы меняется. Сейчас хочу освежить знания и поделиться ими. В отличие от предыдущей статьи, в этой я рассматриваю Linux с более свежим ядром с минимальной конфигурацией на основе tinyconfig, оформленный в виде одного файла и загружаемый при помощи UEFI. Зачем вообще нужно создавать такие сборки Linux? Установил готовый дистрибутив или загрузился в Live — работай и изучай. Но такой подход не даёт настоящей уверенности в знаниях. Представьте: водитель и шофёр. Водитель просто ездит. Шофёр знает устройство автомобиля и может его починить. Современные автомобили сложны — починить всё самому уже нельзя. Но вы можете открыть капот, измерить уровень масла, заменить колесо в случае прокола, установить винт для буксировочного троса и т. д. Так же и с Linux: коммерческий дистрибутив вы вряд ли соберёте, но на одну ступеньку вверх по лестнице профессионализма подниметесь. На мой взгляд, описание создания минимального Linux не должно быть большим, поэтому я старался его сделать минимально возможным, вложив максимум смысла. Как минимальный Linux служит для понимания более сложных вещей, так и моя статья даёт базу для дальнейшего более глубокого изучения. В комментариях к моей предыдущей статье я видел замечания, что можно использовать buildroot или книгу Linux From Scratch . Скажу только, что я преследую другие цели: собрать минимальный Linux без использования специализированных программ и сделать это как можно проще. Всем, кого заинтересовало, добро пожаловать под кат.

[Перевод] Собираем и запускаем минимальное ядро Linux
Однажды на работе техлид порекомендовал мне проштудировать книгу Understanding the Linux Kernel Бове и Чезати. В ней рассмотрена версия Linux 2.6, сильно не дотягивающая до более современной версии 6.0. Но в ней явно ещё много ценной информации. Книга толстая, поэтому на её изучение мне потребовалось немало времени. Занимаясь по ней, я решил настроить такую среду разработки, в которой я мог бы просматривать и изменять новейшую версию ядра Linux — чтобы было ещё интереснее. Есть и другие статьи, в которых рассказано, как собрать ядро Linux. Но в этой статье я немного иначе организую и подаю информацию.

I’m really getting fed up with #SheepShaver. It loves to crash at random when doing any of the following:
- clicking on an icon on the desktop and attempting to drag it (freeze)
- clicking on an icon on the desktop and attempting to rename it (freeze)
- trying to open a folder from the finder (bombs)
- trying to connect to an afp server in the chooser (bombs)
- booting the system (sometimes bombs while extensions are loading, sometimes freezes just before extensions start to load)This happens despite re-installing Mac OS 9 from scratch three times. The only thing I use this emulator for is to build the PPC version of #Macstodon, and even managing to get it to do that successfully is an exercise in patience these days.
Anyway, I think I’m going to try setting up #QEMU tonight as my new PPC emulator. I looked into it a couple years ago but it had quite poor performance, hopefully it’s improved since then, but I’ll happily trade that off for some stability!
