aty128fb PCI card on ppc 405ep taihu board

[王重]

Thanks Bill and thanks Wolfgang! VGA BIOS is the problem. I use scitechsoft
videoboot to initialize the card. Videoboot is based on scitechsoft x86emu
which could run x86 code on other platforms. Now I successfully initialized
the card and get the framebuffer information. But the monitor still gets NO
SIGNAL through the card.

 

Serial console shows framebuffer is enabled: 

 

     videoboot: Booting PCI video card bus 0, function 0, device 6

     aty128fb: Found Intel x86 BIOS ROM Image

     aty128fb: Rage128 BIOS located

     aty128fb: Rage128 RK PCI [chip rev 0x2] 32M 64-bit SDR SGRAM (2:1)

     fb0: ATY Rage128 frame buffer device on Rage128 RK PCI

 

Some information I get from framebuffer:

 

     id = ATY Rage128

     depth =  16

       smemlen = 33554432

       line_length = 0

       FB_TYPE_ = 0

     type_aux = 0

     FB_VISUAL_ = 3

     xpanstep = 8

     ypanstep = 1

     ywrapstep = 0

     mmio_start = bbffc0000d

     mmio_len = 8192

     accel = 32

     xres = 640

     yres = 480

     xres_virtul = 640

     yres_virtul = 480

     xoffset = 0

     yoffset = 0

     bits_per_pixel = 16
