ATI Radeon 32MB PCI, Apple 17 Flat panel on B+W G3

ATI Radeon 32MB PCI, Apple 17 Flat panel on B+W G3

[Kevin B. Hendricks]

Hi,

I just bought an ATI Radeon 32M PCI video card (with dvi output) so that I
could connect up a new Apple 17" flat panel display to my old B+W G3.

(dual video cards)

Any chance these are supported under PPC Linux?

What kernels and XFree86 versions support ATI Radeon 32Meg PCI cards?

What about Apple flat panel displays?

Thanks,

Kevin

Ben's kernel and also current XFree86 have Radeon support.

Hi,

Thanks!

I will give them a try.

Radeon framebuffer support is also in -linus finally, so all of the
trees should support it.

The version in -linus is slightly outdated afaik. Also, you may have
to do the usual tweak to get the PLL right ;) (very similar to r128).

Ani and I have found some ways to fix that PLL issues once for all
(basically, we have some code to really probe the refclk), and afaik,
ATI OF drivers for radeon will actually give that info in the device
tree (finally !).

If you send that patch along, I would be happy to test it for you.

Hi Kevin,

Ben's kernel tree has a relatively recent version of radeonfb, I will
send out an updated newer version in a couple days.  As for X, you can
build 4.1.0 and apply the patch I have in my dir on ftp.linuxppc.org
(users/ajoshi/radeon) or you can build X cvs which has my fixes applied.
DRI support is still in progress.

Flat panel support in radeonfb will be nice, I will try and send you some
code over for that as I do not have a flat panel display.

Hi Ani,

Fire any patches my way and I will test them all.

Unfortunately, I am having trouble with my scsi controller under 2.4.X
kernels so I will have to solve that first (my linux fs is all on external
scsi drives).

I will let you know when I finally get a working 2.4.X kernel and can
start debugging flat panel support on the Radeon.

Thanks,

Kevin

        What is supposed to be missing as far as flat panel support is
concerned?  I just got the same Radeon card connected to a Samsung
flat panel and it seems to work (in digital mode).  I'm using Ben's
rsync kernel (2.4.11-pre4-ben0) with Fukui-san's XFree86 4.1.99
RPM's. I have an old world machine though, so I use BootX to boot.

        By the way, how do you specify the video mode at boot time?  I
had to change the default video mode in radeonfb.c to 1280x1024-8@61
since the Samsung doesn't seem to like 640x480-8@60.

do we need -fPIC for X11R6 modules

[Kevin B. Hendricks]

Hi Ani,

Quick question.  Should we be building X11R6 modules with -fPIC?  When I
try, the resulting modules generate lots of unresolved symbols (like
"fixup", etc).

What exactly are X11R6 modules?  Are they shared libraries?  If so, they
should be built using -fPIC?  If they are not shared libraries, how are
they "loaded" and "linked" in?

If they are "loaded and linked" into a normal shared library, then -fPIC
should be used anyway.

I guess I don't understand how a load-on-demand module can be created
without -fPIC.

Any guidance you (or anyone else :-) might provide would be greatly
appreciated.

Thanks,

Kevin

I assume you mean XFree86 modules?

No, they are ordinary object files, which get loaded and linked into
the running XFree86 server process using linker code that is included
in the XFree86 server.  That is, the server mallocs some memory, reads
in the text and data and other stuff, processes the relocations, and
puts the symbols into its internal symbol table.

That means that for code in XFree86 to call a procedure in a module,
it has to do an explicit "lookup symbol" function call to get the
address of the procedure and then an indirect function call.

So no, we don't want -fPIC.  That introduces a whole new and different
set of relocations into the object file and I would be surprised if
the XFree86 loader knew how to deal with them.

Re: ATI Radeon 32MB PCI, Apple 17 Flat panel on B+W G3

[Kevin B. Hendricks]

Hi Ben,

Total failure.

It seems my setup and all 2.4.X kernels seem to hate each other.

After a few minutes using Dan Burcaw's 2.4.8 or your 2.4.6 (I want to keep
the potential to use my firewire cdrom rw), I get tons of the following
messages:

aic7xxx_abort returns 8194

(I have an extra Apple external scsi card to drive my scsi devices which
have the linux side of things).

and my bash prompt goes away and I am basically hosed.

This does not happen with the 2.2.19 kernel I have been using.

As for the ATI Radeon, it is assigned /dev/fb1 but never lights up.
It is recognized but according to dmesg but no luck actually using it.

Of course, the kernel itself barfs as above.

I have reverted to my old monitor and my old 2.2.19 kernel.

Any hints on how to attack this would be greatly appreciated!

Thanks,

Kevin
