Hello,
In the initialization, why are pll->min_pll_freq and pll->max_pll_freq
taken from R128_BIOS32, when pll->reference_freq, pll->reference_div,
and pll->xclk are taken from R128_BIOS16?
Relevant code section:
if (!info->VBIOS) {
xf86DrvMsg(pScrn->scrnIndex, X_WARNING,
"Video BIOS not detected, using default PLL
parameters!\n");
/* These probably aren't going to work for
the card you are using. Specifically,
reference freq can be 29.50MHz,
28.63MHz, or 14.32MHz. YMMV. */
pll->reference_freq = 2950;
pll->reference_div = 65;
pll->min_pll_freq = 12500;
pll->max_pll_freq = 25000;
pll->xclk = 10300;
} else {
CARD16 bios_header = R128_BIOS16(0x48);
CARD16 pll_info_block = R128_BIOS16(bios_header + 0x30);
R128TRACE(("Header at 0x%04x; PLL Information at 0x%04x\n",
bios_header, pll_info_block));
pll->reference_freq = R128_BIOS16(pll_info_block + 0x0e);
pll->reference_div = R128_BIOS16(pll_info_block + 0x10);
pll->min_pll_freq = R128_BIOS32(pll_info_block + 0x12);
pll->max_pll_freq = R128_BIOS32(pll_info_block + 0x16);
pll->xclk = R128_BIOS16(pll_info_block + 0x08);
}
