System is deadlocked on memory -- Tinycore Linux 11 in browser (WASM)

[ARyaskov]

Hi!

First of all, thank you for really amazing project!

Trying to boot TinyCore Linux 11 (http://tinycorelinux.net/) in browser (WASM)

and get System is deadlocked on memory error (see attached screenshot).

Compiled with node makefile.js emscripten release --enable-wasm Emscripten info: emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 1.39.9, clang version 11.0.0 MacOS

Run in Chrome 80 via serve npm package (via http://localhost:5000/?cda=tc11os)

I think the system is out of memory -- how can I increase available RAM for OS (e.g. via browser address line parameters?)?

Thank you!

Hi,

The mem parameter controls the amount of emulated RAM (i.e. http://localhost:8080/index.html?cda=tinycore&mem=128 for 128 MB of RAM). Some options are in runtime.js

TinyCore Linux won't boot because of some problems with ATAPI sector caching. I think it's the same bug that makes Ubuntu crash if it's booted with a CD-ROM attached.

With the latest commits TinyCore Linux boots, and the mouse works. I found that 64 MB of RAM and 4 MB of VGA RAM works well.

For some reason, the desktop icons don't render in the WebAssembly version, but you can still open the terminal and a few other apps by bringing the right-click menu.

Hi, sorry for late reply! Thank you very much for fixes have been done! I've recompiled Halfix from latest commit. But I'm still no reach my goal -- run any modern Linux-based OS (with v3 or v4 kernel) in browser relatively smoothly (it's not possible to run it in browser at full speed at the moment of course :) ), not in a native app.

Here is my journey for run various OSes in browser wasm (node makefile.js emscripten --enable-wasm release):

dsl-4.11.rc2 from cd

index.html?cda=dsl-4.11.rc2&mem=256

tinycore from v3 to v11 from cd (booting in command-line only mode)

index.html?cda=tcos&mem=128

does not work

while booting the kernel stage:

Enter into setup mode, failed while 'Select HardDrive for install' stage (No harddrives are available)

FreeDOS 1.2 from hd (preinstalled with qemu https://github.com/palmercluff/qemu-images/tree/master/freedos-1.2)

🔥 boots and it's possible to run any command in command line

KolibriOS 0 7 4 from hd (preinstalled with qemu https://github.com/palmercluff/qemu-images/tree/master/test-images/kolibri-os)

🔥 works with GUI, but very slowly (about 5 seconds for its notepad version opening)

MenuetOS preinstalled with qemu

Hangs while booting (I can not enter any number from keyboard in order to specify the variant of OS loading, pressed keys got no response from OS)

@ARyaskov MenuetOS (from the original floppy disk) seems to work fine, I downloaded the floppy from M32-086B.ZIP and it runs perfectly. A recent commit has fixed floppy drive emulation in the browser.

http://localhost:8080/halfix/index.html?fda=disks/menuet&mem=64

During boot, I chose 24 BPP 800x600, use preset, no MTRR accleration, PS/2 mouse, 64 MB RAM, and image from floppy.

Thanks for the bug reports, they're helping me fix a lot of issues.

ReactOS LiveCD works well in the browser.

http://localhost:8080/home/jkim13/Desktop/halfix/index.html?cda=disks/reactos&mem=128

There are some VGA glitches (no icons), but they happen on the native version too. They go away if you enable PCI VGA.

I haven't tried installing it, but it should work, in theory, if you attach a blank hard drive image (http://localhost:8080/halfix/index.html?cda=reactos&hdb=300Mempty. All the changes to the image will be erased on the next page refresh, however.

Somewhere in the last few commits, major bugs preventing TinyCore and Damn Small Linux from booting in the browser have been fixed. I'm not sure how exactly I fixed these bugs, but I guess that all that matters is that they're gone.

Anyways, I revamped index.html by making it prettier and easier to configure. If you know of any other operating systems that don't work, please let me know.
