lspci -xxx -s 0:1F.0 ?

[Riko Ho]

Everyone,

How can I use the result from

sudo lspci -xxx -s 0:1F.0

inside this function ?

static void ich7_enable_lpc(void)
{
     // Enable Serial IRQ
     pci_write_config8(PCI_DEV(0, 0x1f, 0), 0x64, 0xd0);
     // Set COM1/COM2 decode range
     pci_write_config16(PCI_DEV(0, 0x1f, 0), 0x80, 0x0010);
     // Enable COM1
     pci_write_config16(PCI_DEV(0, 0x1f, 0), 0x82, 0x140d);
     // Enable SuperIO Power Management Events
     pci_write_config32(PCI_DEV(0, 0x1f, 0), 0x84, 0x007c0681);
}

are they correctly defined or something not right ?

This looks good, because lspci tells you this: 60: 8a 89 89 8f d0 00
00 00 89 80 80 8f 00 00 00 00
> // Set COM1/COM2 decode range
> pci_write_config16(PCI_DEV(0, 0x1f, 0), 0x80, 0x0010);

This looks good, because lspci tells you this: 60: 8a 89 89 8f d0 00
00 00 89 80 80 8f 00 00 00 00
> // Enable COM1
> pci_write_config16(PCI_DEV(0, 0x1f, 0), 0x82, 0x140d);

lspci's output: 80: 10 00 07 34 01 08 3c 00 91 02 1c 00 00 00 00 00
change this to pci_write_config16(PCI_DEV(0, 0x1f, 0), 0x82, 0x3407);
> // Enable SuperIO Power Management Events
> pci_write_config32(PCI_DEV(0, 0x1f, 0), 0x84, 0x007c0681);

lspci's output: 80:  01 08 3c 00

(correct me if I'm wrong)
change this to pci_write_config32(PCI_DEV(0, 0x1f, 0), 0x84, 0x003c0801);
