Hi, Uwe Koziolek
Thank you for your help.
Accroding to your advice, I thought there was some problem in enabling
the SATA2 port.
And then I get the infomation from sis in china, the port2_start=0x10,
so I added it into sata_sis in 2.6.18 and 2.6.20.
if(pci_get_device(PCI_VENDOR_ID_SI, 0x0966, NULL)) {
pci_read_config_dword(pdev, 0x64, &val);
if (val & 0x10000000) {
dev_printk(KERN_INFO, &pdev->dev, "Detected SiS 1182/1183/966L SATA
controller\n");
} else {
dev_printk(KERN_INFO, &pdev->dev, "Detected SiS 1182/1183/966 SATA
controller\n");
pi.flags |= ATA_FLAG_SLAVE_POSS;
}
} else
{
dev_printk(KERN_INFO, &pdev->dev, "Detected SiS 1183/968+ chipset\n");
port2_start = 0x10;
}
I dont know whether it is needed to make patch for official source code.
You Please.
Finally, thank you very much. Keep in touch.
