[Linux-fbdev-devel] ATI Rage XL with no BIOS support

[Alan C. <ala...@gm...>]

Hi all,
I want use ATI Rage XL on an embedded hardware, I see Linux kernel 2.6.x ha=
s
support to initialize this board although Geert Uytterhoeven say me it will
be removed from Linux kernel because it don't work or is broken.

Anyway I am using kernel 2.6.12, it have support initialize Rage XL. I do
some tests, but it don't work, kernel crash (it just stop) at
"aty_st_pll_ct(VCLK0_FB_DIV, 0xDA, par)", I think it is because my board
parameters is incorrect.

I want know how to found all parameter to struct xl_card_cfg_t (xlinit.c) t=
o
make my board work?

static const struct xl_card_cfg_t {
        int ref_crystal; // 10^4 Hz
        int mem_type;
        int mem_size;
        u32 mem_cntl;
        u32 ext_mem_cntl;
        u32 mem_addr_config;
        u32 bus_cntl;
        u32 dac_cntl;
        u32 hw_debug;
        u32 custom_macro_cntl;
        u8  dll2_cntl;
        u8  pll_yclk_cntl;
}

This is my board:
Vendor: 1002
Device: 4752
0000:01:01.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev
27) (prog-if 00 [VGA])
        Subsystem: ATI Technologies Inc Rage XL
        Flags: bus master, stepping, medium devsel, latency 32, IRQ 9
        Memory at f0000000 (32-bit, non-prefetchable) [size=3D16M]
        I/O ports at a000 [size=3D256]
        Memory at f2000000 (32-bit, non-prefetchable) [size=3D4K]
        Capabilities: [5c] Power Management version 2

Thank you very much,
