status of rivafb versus Geforce FX cards?

status of rivafb versus Geforce FX cards?

[Jurriaan]

The current rivafb driver doesn't support anything after the Ti-4600
cards, if I read it correctly.

Is this being worked on?

Thanks,
Jurriaan (whose FX-5700 card is not supported in framebuffer, and not
supported in Debian's latest XFree :-( )

Just to reply to myself:

Kernel command line: root=/dev/md3 video=rivafb softrepeat=1 mem=256M console=ttyS0
fbdev: probing for matroxfb
fbdev: probing for rivafb
fbdev: probing for radeonfb
rivafb: trying pci_register_driver()
rivafb: starting probe.
rivafb: getting architecture.
rivafb: device 0342, arch 48
rivafb: nVidia device/chipset 10DE0342
rivafb: nVidia Corporation NV 36 [GeForce 5700]
rivafb: NV_ARCH_30 support is experimental!
rivafb: RIVA MTRR set to ON
rivafb: PCI nVidia NV30 framebuffer ver 0.9.5b (128MB @ 0xE0000000)

With help from Mark Vojkovich, who pointed me to what exactly changed in
XFree86 to support the FX-5700, I'm now here. It boots without crashing.
Unfortunately, clock programming is off somewhere, this default mode,
which should look like

Opening frame buffer device `/dev/fb0'
Using current video mode from `/dev/fb0'

mode "640x480-60"
    # D: 25.176 MHz, H: 31.469 kHz, V: 59.942 Hz
    geometry 640 480 640 480 8
    timings 39721 40 24 32 11 96 2
    accel true
    rgba 8/0,8/0,8/0,0/0
endmode

instead has

fh 201.8 kHz
fv   0.0 Hz

according to my Eizo monitor. So I'll have to compare rivafb and
XFree86's nv driver some more.

But progress is being made.
