From PCI config space, the VENDOR_ID and DEVICE_ID are correct for my driver. However the PCI_COMMAND register of 88SE6121 I got is 0x7, which is the same as default value. Based on the document, it has to be 0x0207 to enable interrupt. However I always failed to do so, the
Bit 10 (mask 0x0200) is fast back-to-back enable, what does it have to do with iterrupts.
value remains 0x7 after it is re-assigned to the new value 0x0207. So
This means that fast back-to-back is not supported
that I have no interrupt from PCIe as INTA. Do you have any idea on this issue?
There's also bit 11 (mask 0x0400) meaning INTx emulation *disable*.
Thanks for your help,
