Newcomer issues

[copy]

• Resolution 640x480 and less is enlarged 2 times #431
• How to disable sound? #333 (add a mute button and/or fix the "requires a gesture" warning). A volume selector would also be nice.
• There's a minor issue where holding down and moving the mouse on the screen selects text outside of the screen on Firefox
• Retry XHR requests that fail with 5xx or time out, with exponential backoff
• Add configuration via url parameters (Config file for v86 #448 (comment))
• Non-integer scalings look pixelated in Chromium
• Screenshot for text mode #441
• read_file returns null for empty file #659
• Expose some constants as runtime flags (e.g. https://github.com/copy/v86/blob/adb17b7/src/rust/config.rs#L2 https://github.com/copy/v86/blob/0a359a2/src/rust/jit.rs#L328 -> ?jit_disable=1&jit_max_pages=1)

Some more tricky ones:

• Support more VIRTIO Devices #405 (virtio-tablet would be interesting)
• Port something from JS to Rust (see 03d6595, 50ce752 for an example)
  • apic.js
  • pit.js
  • rtc.js
• Change removable media (floppy and cdrom) while running #54
• Mousewheel support in the ps2 code
• Windows 2000: serial port not working #652 / Issues with serial port on Win9x hosts #610
• Add support for qcow images #591
• android keyboard not working #262 (also affects iOS)
• Better touch support (scale the screen to the browser width, pinch-to-zoom, double-tab for right click) (Double-click and dragging not working on iOS #275, Prevent overscroll on touch-based devices? #386, Touch screen issues #584)
• In-place writes to disk images (i.e., a user selects a local foo.img, and changes in the VM are directly written to that file), see https://web.dev/file-system-access/ (Direct writes to local disk images #396)

Very difficult:

• Unimplemented: PAE #97 (prerequisite to x86_64)
• x86_64 support #133
  • See Tips for implementing x86_64 support #648 (comment) for some ideas
• Improve the performance of the generated code or the jit (e.g., adopt [WIP] Avoid computing flags even lazy #466)
• Implement a linux user-mode: Run a Linux binary under emulation #626 (comment)

Hi, my name is Koshik and I am a student at UT Austin. I'd like to work on this issue (Exposing some constants as run-time flags) as part of my virtualization class assignment.
I see that src/cpu.js is calling the function in cpu.rs and I need to pass the parameter parsed by get_query_arguments. Do you have any example where a run-time flag is passed from a JS source file?
