Disk

[RossComputerGuy]

I am working on my os. I want to be able to access the disk to read and write to it. Does anyone know how to?

@SpaceboyRoss01 unfortunately there is no disk driver in the system at the moment, so no way to access the disk. Discussion here https://github.com/runtimejs/runtime/issues/74

So, I have to write the drivers myself?

[iefserge]

It can be done, but it's a pretty big task (needs VIRTIO-BLK driver, VFS, filesystem driver). For now runtime.js is more like diskless network system.

I am working on a module, you can see the code on my git repository. The os uses 2 VFSs, 1 is the main hard disk, the other is written in json.

[iefserge]

Ah nice, I think the missing key component is VIRTIO-BLK driver to access the actual disk. I haven't looked into it much, but feel free to hack on it if you'd like, I might be able to help too. Disk support would definitely be a great addition to the system.

@iefserge would you like to help me work on BasicOS?

BLK driver and VFS can live in runtime.js repository. You'll be able to access filesystem the same way as in node

require('fs').readFile(...)

But that would need the filesystems to be mounted somewhere, or that the 'fs' module do request to a VFS server that's the one that talks to the hard disks, isn't it?

If It's not yet designed, I would prefer the second microkernel-like alternative instead the first monolythic one. I know it would not be as performant, but definitely it will be easier to design and develop and more flexible. El 7/7/2016 20:19, "Serge" notifications@github.com escribió:

One VFS does, the other works on top of the other.

[iefserge]

Yeah, FS will talk to VFS. VFS will handle mounting and will have its own API. There is no design yet, microkernel-like is basically running in a web worker. That would be awesome, provided performance is ok.

[piranna]

Sorry, I forgoy runtime.js has a single memory space... Then it would be trivial to design it microkernel-like and being still performant since message passing would be a single call to WebWorker.postMessage(), and at the same time it would be easy to test and use independently, I like it :-)
