pm3fb driver is ok in 2.5.24

pm3fb driver is ok in 2.5.24

[Sven Luther]

Hello, ...

I have compiled a 2.5.24 kernel and added the few things needed to make
the pm3fb work (basically, i had to patch Config.in and Config.help so i
could enable it in the configuration process).

Is there a reason why it was not enabled previously, or is it just
forgetting the these two files (which probably did not patch correctly
due to the Config.in and Config.help location and format change).

Anyway, it works fine (well as good as with the 2.4.x kernel), there
still is problem with the copying of the text console data at bootup,
but apart from that everything is fine.

Should i send over a patch for adding it to the Config.xxx files ?

Friendly,

Sven Luther

Could you send me the patch please ?

I though the old-format drivers wouldn't work so I never bothered
submitting for inclusion.

Good news. I already included Config.help and Config.in entries for the
PM3 driver. As a note please consider porting it over to the new fbgen
api. I'm going to removal the old fbgen code soon.

It's on my TODO list, and has been for months.
But I still can't get 2.5.x to compile, much less work,
on my PPC box. So there's not much I can do ATM.

nice :)))

> api. I'm going to removal the old fbgen code soon.

how soon, and is there documentation or sample code for the changed api
?

BTW, i suppose now it will be easier to implement dual head with a dual
output board ?

According from a recent message by James Simmons on LKML:

So pm3fb won't work anymore I guess (due to the ultimate brokenness
of linux on PowerPC I haven't yet ported pm3fb to the new API).

But it works fine right now on linus's 2.5.24, with the above sent
patch.

But it does need porting, i guess.

Have you tried the BK ppc tree for 2.5.X? Dose it work? I noticed there
were some updates just a few hours ago.

My usual tree (BenH) has a 2.5 variant, locked a 2.5.8pre3...
I'm willing to try another one, but I'm still disapointed
that regular Linus kernel can't even compile main.c on PPC.

Just tried: all rsync access seems locked on 2.5.8pre3,
and of course debian doesn't have bitkeeper in packages.
And bitkeeper download site isn't really user-friendly
(guess the "let's register yourself before download"
attitude explain why it's not in debian, and not on my
system either).Xorsis (ppckernel.org) has nothing
beyond 2.4 ATM.

Well, I'm still waiting for an accessible, ppc-usable
2.5.[something big enough] before I can port pm3fb.

For accessibility, try rsync source.mvista.com::linuxppc-2.5 .

Don't know about usability yet though. :)

It's the one I tried, last time I checked (around 2.5.23),
it was still in 2.5.8pre3 (i.e., w/o the new framebuffer layer).

Thanks for the tip anyway, I'll try it again, just in case.

It's at 2.5.30 now at least.

Thanks, but this doesn't help: beside the not really
needed serial ports and floppy drive, the SCSI
drivers also don't compile. And this box has no
IDE channel.

It's better than it once was, but it still 2.4.x
only for me :-(

Thanks for the help,

Good news: Only 53c94 doesn't compile, but MESH is OK,
           and linux is on the internal bus (w/ MESH)

Bad news: arch/ppc/kernel/process.c doesn't compile.

So the conlusion stand: 2.4.x only for my box ATM

In the next few days. Take a look at several drivers that have been ported
over. Plus take a look at skeletonfb.c. It details alot. If you have
furthur questions feel free to ask.

Yes :-) ON struct fb_info for each framebuffer and a struct xxx_par for
the hardware. In this case your xxx_par struct would be shared betweem
each struct fb_info.

Well, the only problem is that i don't have much time :(((

But i will have a look at it.

do i need to get the bk tree, or can i start working with the 2.5.24
linus tree i now have ?

Maybe there is a patch available somewhere ?
