Dear linux-fbdev developers,

About a week ago, Geert Uytterhoeven forwarded 2 e-mails from me to this
list. Since I haven't received any replies yet, and since the (public)
archives at
http://sourceforge.net/mailarchive/forum.php?forum=linux-fbdev-devel
don't show my post yet (in fact, they don't show anything more recent
than april 4, 2004), I was wondering if anyone already replied to the
list and forgot to CC to me.

If anyone already replied, could someone please send those replies to
me? And if nobody has replied, does anyone have a clue on how to get
dual head consoles working with 2.6(.6) on an ultra sparc (or, if it's
broken, where I should start looking to find the actual problem)?

Best regards

Admar Schoonen

Subject: Sun Blade 100 with 2 pgx64 (ATi Mach64 ?) framebuffers

Dear Geert Uytterhoeven,

I have a Sun Blade 100 ultra sparc with 2 pgx64 framebuffers, one on
board and one pci. The machine is running an up to date Debian GNU/Linux
unstable. With linux 2.4.24, both cards work fine (I can move consoles
around with con2fbmap and XFree86 sees 2 cards and starts an X server on
both screens (I haven't tried xinerama though)).

With 2.6.6, this doesn't work anymore. dmesg output seems good:
$ dmesg |grep -i aty
atyfb: 3D RAGE (XL) [0x4752 rev 0x27] 8M SDRAM, 29.498928 MHz XTAL, 230
MHz PLL, 100 Mhz MCLK
fb0: ATY Mach64 frame buffer device on PCI
atyfb: 3D RAGE (XL) [0x4752 rev 0x27] 8M SGRAM, 29.498928 MHz XTAL, 230
MHz PLL, 100 Mhz MCLK

but the second head stays black if I try to move consoles. Also, XFree86
only sees my onboard card.

I don't know how I should debug this issue, but I hope you can give me
some clues.

Best regards

Hi Geert Uytterhoeven,

Sorry, but I forgot to add that I had to apply a small patch to 2.6 to
make it recognize the on board pgx64 in first place. The patch is a one
liner to get around the fact that XFree86 not knowing the new 2.6 pci
device naming scheme, and I don't think it is causing the problem I have
with 2 pgx64 framebuffers.

The patch is at
http://lists.debian.org/debian-sparc/2004/02/msg00013.html

Best regards

Admar
