waydroid VS QEMU

Android on the desktop works very well on Wayland with Waydroid and it even supports Google Play store. https://waydro.id/

Great running apps not available on Linux with a touchscreen PC. It only seems to run Android apps compiled for x86, but it is very fast.

There are practical use cases, and it is very usable. I haven’t tried it on WSL2, but it seems like a practical approach without reliance on Microsoft.

There's a piece of software called Waydroid[1] that allows you to run Android applications on GNU/Linux platforms - including the PinePhone. Sxmo, despite its name, can run Wayland instead of X and therefore supports Waydroid.

Personally, I haven't managed to get Waydroid to work, a task hindered due to some massive initial downloads which are required to set it up. However, I haven't tried particular hard, and there are videos online by those more successful than me[2].

I thought it was uncharacteristic of to see a service like this offered by a large tech company, and wanted to share.

Check out the Waydroid application.

I have setup an Arch linux server on my old pc. i mainly use it for plex, transmission, docker etc and it works pretty well! I wanted to install Waydroid https://waydro.id/ on that server. Is there a way that I can view waydroid using a VNC viewer on my laptop on the same network? is it possible or would I have to install a GUI like xfce before installing waydroid to view the same on tigervnc or some other VNC viewer? Thanks & regards.

Same here. Sometimes, it crashes on a measly 4 GB of RAM.

I would recommend using Waydroid[1]. It runs fairly well in my use case, and runs LineageOS on top of it with the full LineageOS GUI.

i am using KDE Neon (user edition) on two machines (thinkpad laptops with intel). On mentioned machines i would like to try and use waydroid: https://waydro.id/ Waydroid required wayland as display server (it will probably not work on x11).

Waydroid is rebuilding the original idea behind Anbox with explicit focus on modern Wayland powered desktop environments.

My most-wanted QEMU feature: https://github.com/qemu/qemu/commit/a2260983c6553

Using `gic-version=3` on macOS you can now use more than 8 cores on ARM chips.

A better solution is just to write a plain ass shell script that tests if various C snippets compile.

https://github.com/oilshell/oil/blob/master/configure

https://github.com/oilshell/oil/blob/master/build/detect-pwe...

Not an unholy mix of m4, shell, and C, all in the same file.

These are the same style as a the configure scripts that Fabrice Bellard wrote for tcc and QEMU.

They are plain ass shell scripts, because he actually understands the code he writes.

https://github.com/qemu/qemu/blob/master/configure

https://github.com/TinyCC/tinycc/blob/mob/configure

OCaml’s configure script is also “normal”.

You don’t have to copy and paste thousands of lines of GNU stuff that you don’t understand.

Also, it would be nice if there was a WASM (soft) CPU for QEMU, which (if it existed!) would go here:

> architectural registers are always updated

In tiny code, the guest registers (global TCG variables) are stored in the host's registers until you either call an helper which can access the CPU state or you return (`git grep la_global_sync`). This is the reason why QEMU is not so terribly slow.

But after a check, this also happens when you access the guest memory address space! https://github.com/qemu/qemu/blob/master/include/tcg/tcg-opc... (TCG_OPF_SIDE_EFFECTS is what matters)

But still, in the end, it's the same problem. What QEMU does, can be done in LLVM too. You could probably be more efficient in LLVM by using the exception handling mechanism (invoke and friends) to only serialize back to memory when there's an actual exception, at the cost of higher register pressure. More or less what we do here: https://rev.ng/downloads/bar-2019-paper.pdf

Um, in case you don't know, UTM (based on QEMU) is out for quite a while.

Some of these tools include Oracle VM VirtualBox (that I've used since before the acquisition of Sun Microsystems by Oracle), VMWare Workstation Player, and QEMU, but last year, I found out about Multipass.

For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:

https://mesonbuild.com/Wrapdb-projects.html

https://mesonbuild.com/Wrap-dependency-system-manual.html

meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:

https://github.com/harfbuzz/harfbuzz/tree/main/subprojects

https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...

Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

For all the users of the Linux platform, QEMU is the VM that you should go for. This software comes without any price tag and works as an emulator of various machines with utmost ease and completion; the software uses dynamic translations to emulate hardware peripherals and enhances its overall performance. If you are using QEMU as a virtualizer, then it will function exactly like the host system (provided you have the right set of hardware).

In this tutorial, we set up macOS and Windows virtual machines on UTM, a macOS application that provides a GUI wrapper for QEMU, a powerful open-source emulator and virtualizer. UTM allows you to easily manage and run virtual machines without memorizing complex commands. It also has special handling for macOS, making it simpler to install compared to other virtual machine software.
