RedHat PSP Linux Port

Danny769 · Post by **Danny769** » Mon Feb 06, 2006 4:22 am

Well i got it to work

one little problem
took about 190 min to load the full Distribution.

any one have any ideas?

Distrib: RedHat 6
Size: 512mb

I would be happy for some help
cus no one is going to want to use this with a 3 hour load time
as well as taking half a gig

You should better try to port something like Tiny Linux or Damn Small Linux (both only 50MB in size) instead of a full blown distribution. The latter just has too much memory need and unneeded programs and drivers, which make loading time unbearable on older machines, and thus on something like the PSP.
Tiny Linux runs on a 386 with 8MB of RAM, so this would more likely fit the specs of the PSP.
Then whenever you finished to get it work, you'd have to get some driver working to support the GU probably, to make a desktop or anything with graphics possible. Also, get rid of all unneeded drivers and the detection routines (monitor/graphics card/network card/sound card/etc.).

Still a great achievement to get Linux running, hands up ;)

Ok lets scrach linux for a min
i can run any os i like

I am going to strip down a homebrewed copy of 3.11 for workgroups
update the vb runtime libary
and add a nice little freeware softwear bundle

then im gona through in the 88w8310 drive, and add netscape 3

What you all think
does it sound resionable

the whole idea would be that explore wouldnt be cripling the resorces
plus you would be able to run a bunch of native windows apps
compaired to running 95, which is useless

Hi,
Did you actually port linux to the PSP or use bochs to run it? I'd agree with an embedded os rather than a large distro. Voyage linux on the PSP would be quite good.

Danny769 · Post by **Danny769** » Mon Feb 06, 2006 9:11 am

its ported not boched.

if i boched redhat id be waiting 3years for it just to decompress the image
not to mention execution

ill try a small distrib, but i want it to have a decent desktop

Any one know a good 16bit, or lower32bit onscreen key board

16bit is pefered

funetik · Post by **funetik** » Mon Feb 06, 2006 11:15 am

Not too sure about the onscreen keyboard ^

I like slax, but it could be a little too big - http://slax.linux-live.org/

Might be interested in this though - http://www.menuetos.net/

I like it, but id rather create my own os.
It will use a homebrew 3.11 as its code
so i get all the VB rintimes

And i want to incorporate networking and a win9X type interface
while avoiding the implimation of windows explore.

so in sort ill be gutting win 3.11
and making a VB interface, that looks like win95
and can execute a number of 32bit apps

funetik · Post by **funetik** » Mon Feb 06, 2006 1:26 pm

I don't think this is too helpful, considering you said you want to use a modded 3.11, but I'll post it anyway, you might be semi-interested :P

im sort of worried about getting sewed now

so i might stick to linux or mabby lingow

Danny769 · Post by **Danny769** » Mon Feb 06, 2006 11:38 pm

im going to go with ReactOS

its under 20mb and apairs to run a varity of VB apliations.
Im only worries as to wether or not it will run windows drivers,
becouse im intrested in getting wifi going through a OS

Sorry did a little reading
it does support windows drivers

Seems to have alot to do with wine
which im a little skeptical about.

but the OS seems to run many windows apps

what are you talking about
Im trying to come up with a way
of using a OS on a ported X86 emulator that i made
which supports psp device calls. It is similar to a boch but it uses the memstick rather then an image.

It should also alow you to use the wifi if, a good driver is signed to the device. I plan on using the 88w8310 windows driver, and hope it is comparable with the psp.

if i can get some thing to run decently we will have a decent PSP OS
rather then a psp shell.

there is so much softwear out there. I just want a way to execute it, with out having to port every single app individuly. You all know how nice it would be to have a workable OS.

ReactOS is small and powerful and looks alot like windows.
It is a decent choice that most psp users would be confortable with.
Plus it is OpenSorce

I plan on setting it up this evening and having it out by next weekend.

If you have any thing you feel would contribute, feel free.
Ill take advice from anyone i fell has a good idea

so come again?
what is the benefit of emulating VB code?
why not just stick to zipslack and have
some linux at least to make better uses
of resources .... am i reading this right
or is this some ps2dev.org joke :P

interesting and utterly useless thread
going on here but hey you can use the
PSP on screen keyboard instead
creating your own.... tutorial is available

No i use linux on every pc in my home, its great
but it has so many problems when ported to the psp

how can you say that?

Is anyone else completely confused as to the validity of this?

groepaz · Post by **groepaz** » Wed Feb 08, 2006 10:09 am

confused about what exactly?

and i still want that stuff danny is smoking!

I guess we'll know soon enough! Meanwhile, groepaz, pass that thing over here...

indeed it must be very strong or

but aside from this thread being a
complete non dev related thread
a question to you danny: do you
please yourself with creating seamlessly
useless topics of discussion and how
are you mapping x86 src for use on

questions that need to be answered ;)

Ya this probly got lost some where, but i was asking what OS you think i should setup.

Im planning on ReactOS, but it isnt exactly out of it Alpha

So what ever you got through it my way

Mandrake mabby?

why don't you start uploading this big fat distrib, so everyone can check :P (or maybe a sort of diff)

What exactly is it that you don't get ? You can't just take any OS you hear about and run it on the PSP.

Even though you have some x86 emulator, you wouldn't get far. All drivers and other low-level stuff would need to be rewritten and you basically have no information about the PSP HW, other than which chips that are in it.

How would you support just simple things like Audio, USB and WLAN ?? And besides that comes the kernel of the OS, which you would need to rewrite to use the API from the PSP Kernel.

Raphael · Post by **Raphael** » Thu Feb 09, 2006 6:43 am

That's not completely true, because that's what the emulator then is supposed to do - create an interface of the real hardware to the hardware the software is aiming at, thus 'emulate' graphics/sound/etc. hardware that the underlying software can handle.

However, I still have to admit I fell for Dannys first post. I really thought he had ported Linux... well, running it over an emulation isn't what I'd expect to be usable in any manner on PSP - even though he says its not 'boched'. Maybe qemued instead? Whatever... not worth my time anymore until I see anything useable.

HaQue · Post by **HaQue** » Thu Feb 09, 2006 10:23 am

I asked him if he ported it or boched it(meaning any sort of emulation). He said he ported it. the x86 emu is actually in another post, so I assumed he knew the difference and was talking about 2 different projects.

If you were going to port linux, why do it with red hat, and 512Mb?
Wouldn't you start with the minimum possible and work from there?
Danny Im not convinced that you know the difference between an OS and just a program running on an emu(like bochs or another x86 emu)

You would have to know a damm lot more about the hardware than what I believe most of us currently do.

I also don't believe anyone with the skills to create an OS would do it to run VB code. Why run such a bloated API on the PSP? If you are going to do that, wouldnt win32 assembler be a better choice? It isnt that hard to write and would take up a lot less space and resources.

BTW,
If you did port linux, how about giving some details on that. And why did it take 190 Minutes to load?

Sorry for being sceptical, but I really dont understand.

crazyc · Post by **crazyc** » Thu Feb 09, 2006 10:34 am

This doesn't make any sense. Linux will never run natively on the PSP due to the lack of an TLB. ucLinux could, but there are a large number of programs in Red Hat that won't run on ucLinux.

Danny769 · Post by **Danny769** » Thu Feb 09, 2006 11:04 am

Linux will never run nativly thats exactly my point.

That is why i am tring to move for an alternet OS

I have a x86 emu, but it is a wast of resorces to emulate a system.
That is why i am moving to use a OS that is still fairly early in its develpment, as well as small in size.

we will have to see how it goes, for now i will put out a copy under emu.
Consider it a beta, that i dont plan on improving on
