[Linux-fbdev-devel] radeonfb cannot map FB

[Rui S. <rs...@gr...>]

Dear Benjamin Herrenschmidt, dear mailing list subscribers,

     I'm trying to load radeonfb for an RV100 QY chipset. Whatever I
type in the modprobe I always get:
       radeonfb (0000:01:0c.0): cannot map FB
       radeonfb: probe of 0000:01:0c.0 failed with error -5

    I've tried latest 2.6.27.x and 2.6.30.x kernels. This a secondary
video card that I would like to connect a monitor to. The first video
card is an Intel 915G, which is working with vesafb.

    Here is the output of lspci -vvv
    01:0c.0 VGA compatible controller: ATI Technologies Inc Radeon RV100

    Can you or anyone give a hint on what I might be doing wrong:
modprobe radeonfb mode_option=800x600-16 panel_yres=600
    Or could this be some kind of hardware issue ?

    Thanks a lot for your help,

radeonfb doesn't currently have any code to post secondary x86 cards
so they won't work unless they have been posted by the system bios.

I suspect your BIOS isn't initializing the secondary card, radeonfb is
thus unable to use it.

However, you probably don't need radeonfb. X.org should be able to get
it going as a secondary just fine, but your text consoles will have to
remain on the intel.

In the long run (though it might already work with latest upstream), the
new radeon KMS should be able to initialize those.

Cheers,
Ben.

Hi Ben, sorry for the late reply ( Motherboard crash),

The system I'm trying to setup is an IBM SurePOS 500. It is supposed to
work on a FB console (no X) in order to play some Videos :)
I'm able to use a usb to vga in order to accomplish this but, using the
integrated Radeon was preferable.
So, you're saying that it is probably a BIOS related issue, not
initializing the secondary Video card. Is there anyway I can make sure
of it? If the BIOS is not initializing it properly, I may be able to
contact IBM about it.

Once again, thanks a lot for your help,

x86 bioses only post the primary VGA card.  For secondary cards you'll
either need to use a driver that can initialize the card itself, or
use something like vgaarb and vbetool to post the secondary card
before loading the driver.  If you would prefer to use the radeon
card, there may be an option in the bios to use the radeon card as the
primary rather than the integrated card, however, that would probably
make the integrated card unusable.

Hi Alex,

    There is no option similar to "Init Display first" on this BIOS.
Howerver both cards must be initialized. I'm trying a radeon kernel
modesetting approach. I'll also pursue vgaarb and vbetool options.
    Thanks a lot for the information ?
