Okay, first of all, don't get me wrong:
i'm just collecting information, i don't promise anything

Okay, after getting this straight, this is my intention for this thread:
- setup a place where information can be found about porting linoleum to linux.
- posting links to sites where information about programming in linux can be found.
- ask Alex a lot of questions about the linoleum RTM.

Well, if you have further additions, let me know.

I have the following plan to develope a linoleum RTM for linux. The very first goal is to get a minimal RTM which can execute: http://www.anywherebb.com/samplesc.html

here's the monologue i had with Alex:
13:22, Alex> ah, well... start by allocating a couple blocks of data
13:23, Alex> one for the code and one for the workspace
13:23, Alex> then setup the [CodeOrigin] at location 0 of the workspace
13:24, Alex> uhm... and compute a pointer that, added to [CodeOrigin], gives the pointer to the entry point of the Isokernel parser
13:24, Alex> and put that in [IsoKernel], at address... well, the first address after the end of the main workspace
13:25, Peterpaul kl h> That's a negative offset?
13:25, Alex> yup, it may be negative
13:26, Alex> then uhm... well... setup a thread, or something similar...
13:26, Alex> and have the thread call the entry point of the program, with a call that needs a simple "RET" to return.
13:26, Peterpaul kl h> jsr call
13:27, Alex> the inizialization paragraph of the RTM, filled by the compiler, gives all the values
13:27, Alex> yes, possibly a near, flat, 32-bit call
13:27, Alex> that is, if you'd like NOT to also rewrite the instruction set
13:28, Peterpaul kl h> No please
13:28, Alex> hmmm... well... egh...
13:29, Alex> not being a working isokernel there, there shouldn't be much left to do
13:29, Peterpaul kl h> This sounds pretty clear.
13:29, Alex> basically the Lino code needs access to the workspace, and to a location that it believes to be the entry point of the Isokernel parser
13:30, Alex> the mappings, as you probably remember, are: EDI = pointer to first location of workspace, EBP = spare register (X)
13:31, Alex> ESP = $, but it may be on the same stack as the RTM
13:31, Alex> then A=EAX, B=EBX, C=ECX, D=EDX, E=ESI, that's all
13:31, Peterpaul kl h> How are all the variables accessed, are they streamed into the allocated workspace?
13:32, Alex> yeah, really all. in such a minimal environment, you might be able to run apps that just perform without the Isokernel
13:32, Peterpaul kl h download linoleum's source.
13:33, Alex> yeah! streamed one after the other
13:33, Alex> (sorry, got disconnected)
13:34, Peterpaul kl h> no problem.
13:34, Alex> one variable after the other: after the last unit of "variables", the first unit of "workspace" is there
13:35, Alex> uhm... although, I suppose, for being at least minimally useful, it might have a way to load and save files, at least
13:36, Peterpaul kl h> Yeah, but the file-section is one of the least hard things to add. At least i think.
13:37, Alex> perhaps... I had a hell of time making the universal syntax thing, though
13:37, Alex> or perhaps because I didn't want the bare no-extension version of the RTM to cross 16 Kb
13:37, Peterpaul kl h> Euhm, what RTM can i use as a refference point? There are eight of them.
13:37, Alex> so I'd better say I had a hell of time optimizing it...
13:38, Alex> the first one is the simplest, without modular exceptions
13:38, Peterpaul kl h> Oh, i won't use such a limitation.
13:38, Alex meant: extensions, damn tiredness
13:38, Peterpaul kl h> let's make something working first. Optimalization comes later.
13:39, Alex> true...
13:39, Peterpaul kl h meant: optimizati.... heck, whatever....
13:39, Alex>

Aren't monologues meant to involve only one person?

*runs away before he gets beaten for being pedantic.... *
i hate it here!

No Jim your right. Dialog is the correct word me thinks.
sun + black hole = fwoosh!

Some of the stuff in http://www.anywherebb.com/postline/posts.php?f=10&t=275 might be useful as well.

Yeah, i think it might be helpfull. We can use all the help we can get .

Yes.... but it still doesn't stop me being pedantic, does it? Now shush. Stop ruining the thread.
poptart fire!

Dialogue is between two people.
Monologue is one person talking. This does not mean they are the only person on the stage. In fact, a number of monologues are basically dramatic rants or speeches.

A soliloquy, though, is one actor talking to himself. Also the only person on stage, if I remember rightly.

Okay, since i'm the one who started this discussion about monologues and dialogues:

I was just kiddin' I just meant that i didn't really have something significant to add to Alex sayings.

I knows.... hence the thing about me being _pedantic_, thanks Ginja.

(and actually it was me, but there you goes... )

Coding has begun

Here's the status thus far.
  • Read Compiler Communication Paragraph (tested)
  • Read the Commandline (tested)
  • Allocate memory for the workspace, initialized to zero
  • Allocate memory for the code, initialized to zero
  • Read initialized workspace from stockfile
  • Read code from stockfile
  • Write commandline paramters in workspace section.

    Only the first two are currently tested, but the rest should follow quickly. I just don't like to switch between Windows and Linux a lot. Booting on both of them is so slow.

    (Reminds me to try the current code in MINIX, which boots in 10 seconds. )

    I know this sounds stupid, but does this mean NoctisV will be available for Windows AND Linux... simultaneously?!

    Oh God. This is so cool!

    When this RTM is finished: YES
    written by Overtilt on Oct 30, 2003 14:53
    Oh, damn! All we need now is a MacOS port for Lino and it'll be all nice and good-like.

    Do you have an estimate on when you expect to be done?

    I could be very anoying here...

    ... Yeah, let's do it:

    when it's ready

    I hope somewhere in January, February. But it's hard to estimate when you don't even have a working version for the most simple program.
