#qemu — Public Fediverse posts

Oh, look, another "revolutionary" kernel that boots in #QEMU 😴. Who knew we needed yet another toy project cluttering our #GitHub feeds? 🙄 It's almost like someone's trying to win an award for the world's smallest C code that nobody asked for. 🏆

Mmuko Boot Sequence – a tiny freestanding C kernel that boots in QEMU

One excellent developer quality of life change that got merged into #qemu last week was #meson support for the #tcg checks. The TCG checks are complicated because they require multiple cross compilers for all the guest tests and meson doesn't really understand the concept. However Pierrick was able to work around that and now you can run individual tests like this:

```
./run meson test --suite tcg aarch64-softmmu-memory-sve aarch64-linux-user-sve-ioctls
```

... und jetzt noch das Sahnehäubchen um euch gänzlich verrückt zu machen: das ist der Host.

Was soll ich sagen ... es läuft
¯\_ (ツ)_/¯

Написал свой ассемблер, чтобы понять, откуда берётся ff010113. Почти половину моей программы он выдумывает

Написал свой ассемблер, чтобы понять, откуда в дизассемблере берётся ff010113. Заодно посчитал, сколько строк моей программы процессор вообще не умеет исполнять, и проверил это на четырёх наборах команд, включая живой ESP32 на столе. На кристалле первая программа серии сломалась: она пишет в UART быстрее, чем провод успевает передавать, и в эмуляторе этого не видно. Что сказала плата?

so i tried to make a nested proxmox vgpu thingy. but it doesnt work cause when i enabled viommu on the vm the nvidia driver fails(RmInitAdapter failed) but when i disable viommu mdev doesnt work cause it needs /sys/kernel/iommu_groups/ which only exsists with iommu. i fucking hate this bullshit.

PSA for anyone using #QEMU #KVM for #SingleGPUPassthrough
Guides are all over the net suggesting hooks scripts invoking pci devices, unloading/loading kernel modules, and other unnecessary things. Here's my current hook script for starting the VM:

systemctl stop display-manager

That's it. And the reverse for teardown:

systemctl start display-manager

#IOMMU groups still apply, and you need to pass the correct PCI devices to your VM, but everything else is handled automatically.

Disclaimer that this is how it works currently for my AMD card. I did have a working setup with my NVIDIA card that did unload/load kernel modules, however it seems things have come a long way since I set that up.

La semaine dernière, j'ai eu la chance d'aller à @UYBHYS , où j'ai rencontré quelques fans - et quelques détracteurs qui ne voyaient pas le crocodile en moi, mais une mouette (ils ont trop mangé de palourdes !).
Ca méritait bien un petit dessin avec des tas de clins d'oeil que je vais laisser à chacun le plaisir de découvrir ;)
PS. Rien qu'avec les crêpes du jeudi soir, j'étais déjà content d'être venu à la conférence - et elle n'avait pas encore débuté. C'est dire.

Does anyone here know how to run #Amazon Linux 2 or 2023 #aarch64 #QEMU images? They seem to hang right after exiting boot services. Latest qemu and #EDK2 i could get on Fedora 42.

Perhaps @hrw knows, or knows someone who knows.

What's a good value for Huge Pages in Linux? I just want to enable them for a QEMU virtual machine.

Directions appreciated.

What says #hacker more then a customized boot logo that is offcentered?

#EDK2 #Taniocore #libvirt #VM #QEMU

Spending some cycles on refining the #qemu package on #archlinux. Now with #arm #uefi support!

Still need to fix up #edk2 to enroll some common certificates in the #firmware blobs.
