I understand what is mesa/gallium/radeon but didn't understood information behind it. Maybe because english is not my native language.

A-EON has some Linux developers working on Linux distro's for the X1000, you'd better ask them. In theory it is possible but it would be a waste of a core for AmigaOS 4.2 if you ask me ;)

Its understood its not a priority at the moment when such major improvements are implemented.
But it would be great for X1000 owners to be able to access to Linux and some valuable apps that are not yet avail for OS 4. That could be a temporary solution until Libre and Timberwolf for example are fully completed.

Thanks for progress update, and its great to see there is a plan and progress (what people have been asking all the time) as well as that OS 4.1.6 users will continue to receive smaller updates.

@wawa

Goals for Gallium 3D are quite nice and should really bring 3D to AmigaOS. Its been a long long way but it seems OS 4.2 will offer such major updates we might call it AmigaOS 5, even that seems to be curse about now

Quote:

Provide a hardware-accelerated OpenGL for applications, games, and the operating system. Provide a driver interface with maximum flexibility. We do not want to count exclusively on Gallium3D as a basis for drivers, although it will be a fundamental one. Provide a low-level API that does not depend on high-level constructs like Windows or Screens. While it should be possible to render to these, it should not depend on any of them. Be able to upgrade to the latest OpenGL version, depending on driver support. Support multi-threading and multiple CPU’s.

Good to hear backwards compatibility is still important. Will 4.2 also support more than 1.5 GB RAM? Or is that impossible with compatibility in mind?

@pavlor

Using seperate address spaces per application, each application could (at least) address 4 GB.

Should we expect a bit more regular communication from you guys. Any news on the netbbook, even if it's just to say that it's now a defunct project.

Wow! Sounds too good to be true. That would make 4.2 milestone in history of AmigaOS (why not call it then OS5 as vox suggested? ).

@Rob

I would really to know more about that netbook really, as I'm really interesting in that.

Yes, me too.


Netbook or other portable computer, that would make many of us happy.

of course, introducing separate address spaces would probably look like that, that those spaces would be placed above the 2gb limit available for legacy applications, leaving the lower adress space for those to use.

@Hyperionmp

Well, if using the extra core for AmigaOS has any drawbacks at all, count on some people to not want it there. Then, using it to run a Linux "for free" would probably be very welcome, so it's something both Hyperion and A-EON should be looking into (if you can run 2 copies of AmigaOS I would be amazed if it couldn't be hacked into booting Linux instead of one of those).

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

The reason the kernel was "forked" into two separate branches it to test backwards compatibility of the kernel with new functionality with both legacy and AmigaOS 4.x applications and software so bugs can be rooted out and compatibility issues can be identified and addressed.

sounds reasonable, is it expected that the new branch will gain enough compatibility to be merged in again, or the old one to be abandoned without need to keep it for compatibility reasons?

Quote:

There is a clear concept defined for multiprocessing since quite some time which is now being implemented. In fact, on an X1000, it is already possible to boot two independent instances of AmigaOS each running on a different core.

running two instances of an os next to each other, or different oses on different cores for that matter, is not "multiprocessing" so far i can tell. besides we have been told that it was already working some two years ago (afair).

@wawa

"running two instances of an os next to each other, or different oses on different cores for that matter, is not "multiprocessing" so far i can tell."

I never claimed otherwise.

Incidentally, you do not understand the concept of seperate address spaces.

Each application would have the entire 4 GB address space for itself (assuming 32 bit addressing). This is nothing new, other operating systems do the same. It involved "context switches" (and no, nothing as severe as the context switches in WarpOS or PowerUP).

i may not understand many things about computers, but i suppose in this case i actually do grasp the concept and know, other contemporary systems are using this. however, im curious, if it is no problem to adress 4gb having a separate 32bit address space at disposal why it is impossible to have full 4gb available within single 32bit address space as it is currently the case on os4 as far as i know?

@wawa

There used to be a limitation in DOS which limited us to 2GB. More importantly, a lot of the 4GB address space is taken up by the mapping of PCI (or PCI-Express) devices AFAIK.

My Windows XP 32 system shows 3.12GB out of 4GB.

So any info on the netbook? Rumour from what you might call a reliable source suggests that it's not going to happen, can you confirm or deny this?

@Rob

Maybe the new power isa is about the netbook...

Freescale e500/e5500 is more likely: Cyrus (new motherboard design from A-Eon) uses these CPUs.

@kamelit0

Power ISA v.2.03 and Power ISA v.2.04 is supported.
I'm guessing Power ISA v.2.06, so this is e500mc or e5500 core.
A2 and POWER7 is unlikely,
now google any CPU or that has this cores.

are you sure its in dos? i mean the limit in dos applies to file size limit, or am i wrong?

i cant find the exact explanaton of the problem atm, even though i remember to have red one, but googling a little on the subject i came across this:

http://www.ann.lu/comments2.cgi?view=1059500517&category=news&start=201

in particular the comment 216 by hj frieden:
Quote:

And finally, the single address space should go away at some point. We'll make a kernel available to developer that has private address spaces. It will break a lot of compatibility, and will reuquire new API's and guidelines (especially for message passing), therefore it will be developer only.

i know, its ten years ago, so ways to work around that have been found in the meantime, or are we still speaking of "a lot of compatibility loss"?
