sata_sil siimage OOPS

sata_sil siimage OOPS

[Rudolf Marek]

Hello,

My friend just switched to new motherboard and wanted to use his PCI
0000:03:04.0 RAID bus controller: Silicon Image, Inc. (formerly CMD Technology Inc) SiI 3112 [SATALink/SATARaid] Serial ATA Controller (rev 02)

To his surprise both siimage and sata_sil oopsed.

I track down a oops to:
writeb(cls, mmio_base + SIL_FIFO_W2);

Code;  e098150a <pg0+2035050a/3f9cd400>   <=====
   0:   88 83 41 02 00 00         mov    %al,0x241(%ebx)   <=====

I checked ioremap and have seen that it requests only 512B while this offset is 0x241 bytes.

In lspci there was also only 512B for this memory region.
cat /proc/iomem

dfec0000-dfedffff : 0000:03:03.0
  dfec0000-dfedffff : e100
dfefe000-dfefefff : 0000:03:03.0
  dfefe000-dfefefff : e100
dfeffe00-dfefffff : 0000:03:04.0
    ^^^^^
    0x200 only

dffff900-dffff9ff : 0000:00:1f.5
dffff900-dffff9ff : Intel 82801DB-ICH4

I have some questions:

Whos fault is it?

1) Fault of bios inside the card
2) Fault of main bios
3) Linux ???

Proposed actions:

1) add check into sata_sil and siimage to see if the memory region is large enough
2) add pci/quirks.c entry

static void __devinit muj_quirk(struct pci_dev *dev)
{
        struct resource *r = &dev->resource[5];

/* some if here to check actual region else fix: */
                r->start = 0;
                r->end = 0x400;

}
/*fix the numbers and routine name */
DECLARE_PCI_FIXUP_HEADER(0x1095,0x3112,muj_quirk );

After applying the quirk.c:

20000000-200003ff : 0000:00:1f.1
20000800-20000c00 : 0000:03:04.0

It works OK now.

I can create neccessary patches if needed.

regards

Rudolf
