FUP to: Booting Sparc Blade 150 w/ ATI Rage XL (xlinit.c)
Grzegorz B. Prokopski
The problem was that in this machine there's also an additional
video card [1] to which the monitor was connected. After switching
monitor output to on-board card - it generally works. Excuse me
- I am really new to sparc hardware (bye bye 3 days of hard trying).
However I am not entirely happy w/ this onboard card.
I *also* have an U10 machine w/
fb0: Creator 3D at 000001fc00000000 type 51 DAC 10
atyfb: 3D RAGE PRO (PQFP, PCI) [0x4750 rev 0x7c] 4M SGRAM, 14.31818 MHz
XTAL, 230 MHz PLL, 100 Mhz MCLK
and an on-board fb1: ATY Mach64 frame buffer device on PCI (unused)
This Creator 3D is:
1. Much faster in displaying changes even though the machine is
~twice slower
2. Doesn't show this strange "scratches" every time anything in the
screen content changes - which is very annoying while I am
using B150's ATY Mach64 on-board card.
Now scrictly about B150 - w/o removing PCI card I get:
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
and this is what I use. (no text console though because I left the
additional PCI card inside, but I get video after X start)
Questions:
1. Is it possible to somehow eliminate these "scratches" while
using on-board card?
Is it normal or am I the only one that gets them? (21'' monitor, not
LCD if that matters). linux-2.4.22.
2. Would it be possible to get this additional PCI card in b150
working under linux? It's XVR-500 in /proc/pci it is seen as:
Bus 1, device 0, function 0:
Display controller: PCI device 3d3d:07a2 (3DLabs) (rev 1).
IRQ 7016480.
Master Capable. Latency=64.
Prefetchable 32 bit memory at 0x1ff04000000 [0x1ff05ffffff].
Non-prefetchable 32 bit memory at 0x1ff03000000 [0x1ff0301ffff].
Prefetchable 32 bit memory at 0x1ff06000000 [0x1ff06ffffff].

While reading "Installation manual" (available in PDF under above
address) I found:
XVR-500 (Expert3D-Lite compatible)
16MB SDRAM display list memory
16MB on-board SDRAM texure memory ...
32MB of frame buffer SDRAM memory
I'd be thanful for any help

Yep, the mach64 is pretty crappy compared to the creator3d.
Also, the creator3D sits on the main CPU bus whereas the
mach64 sits on PCI.

I have no idea what is causing this, most likely inaccurate programming
of the memory timing parameters. Better to ask the xfree86 lists,
Marc La France is the ATI-mach64 expert there, nobody here is very
knowledgable about the details of the mach64 chip.

Unlikely to work without significant hacking of both the kernel
(for console driver) and xfree86 assuming that hardware documentation
exists. I believe there are not even any open source public drivers
for these cards, I wouldn't waste much time on this card.
Better luck you'd get with the XVR-100 which is ATI Radeon based.
But even this would require a bit of work to make sure the existing
Radeon kernel and xfree86 drivers work on sparc64.
