Sun Blade 2500 - 2xCPU/8Gb Ram/36Gb disk/1 x XVR-1200
>Description:
Hi Martin,
finally the 7.1 RC1 is up and running, but I cannot use a GUI.
The "X -configure" command is failing the configuration, because doesn't find the right video card driver. I was searching for ifb driver in /usr/X11R7/lib/modules/drivers, but is missed. Please let me know if you have already prepared an xorg.conf file for XVR-1200, then I'll configure the monitor part with my Samsung LCD.
PS I've installed 7.1 RC1 from CD after a fast swap from original Sun DVD unit to an HP DVD burner.
Thanks,
Maurizio

There is no Xorg driver for the XVR-1200 or any other wildcat-based
cards, not in NetBSD or anywhere else that I'm aware of. It wouldn't be
too hard to write one though, we have limited documentation for at
least a few chips.
The problem is that we get the hardware in a rather weird state - two
framebuffers and a control plane which ( likely among other things )
selects which pixel's colour info is taken from what framebuffer. This
control plane contains garbage and we don't know how to access it.
Currently the kernel's wcfb driver works around this by writing into
both framebuffers.
An Xorg driver would either need to use a shadow framebuffer with a
specialized update routine that writes both framebuffers ( not hard to
do, I did something similar for the mgx board ) or, on boards where we
know how to use the blitter, one could write a simple exa driver with
an UploadToScreen() method that takes care of this.
have fun

Hi Michael,
sad news by your side...
I could swap XVR-1200 to a cheaper XVR-100 64 ( ATI Radeon 7000 - 64Mb).
please could you say me if XVR100-64 is supported with a driver already
present in the distribution?
Thanks a lot,
Maurizio

Yes, XVR100 works out of the box.

Hi Martin,
sorry if bother you.
May the system recognise automatically the new board (XVR-100 instead
XVR-1200) at the boot, or there is a sort of Solaris "boot -r" to reconfig
the new devices, or it's better to reinstall NetBSD from scratch??
Thanks a lot,
Maurizio

No need to reinstall, at worst you would have to edit your /etc/xorg.conf
(but you did not edit that before, and an empty or missing one should mostly
work anyway).

Assuming you are still running the GENERIC kernel (you haven't configured,
built, installed, and booted, a modified version) then all you need to do
is reboot - the kernel looks for hardware that is installed every time it
boots (and for some, that can be hot plugged, whenever it is plugged in.)
Even if you have a modified kernel, it would only matter if you had
removed the driver for new device, and either you don't have support
for modules or the driver has not been modularised - since in this case
the driver for your replacement board is likely the same one as you hoped
would work with the unsupported board, it is unlikely you would have
removed it, even in a custom kernel - so even there just a reboot should
work.
No special boot sequence is required, and there is certainly no benefit
to installing (the same system version) again.

Hello,
the xvr-100 should Just Work(tm) out of the box. The GENERIC kernel has
a driver for it ( radeonfb ) and Xorg should just use the radeon
driver, you don't even need a config file for that.
Also, no need to swap cards - just point the OpenFirmware console at
the xvr-100 and the NetBSD kernel should do the right thing.
Please let us know if there are any problems.
That said, I have an xvr-1200, it's really a shame we can't run X on
it. I'll give it a shot next time I have some hacking time.
have fun
Michael
