If uPD is not attached then FATAL_ERR don't happen. After FATAL_ERR; the Error register FB8h (of PEX8065) for bus "2:01:00" (connected to uPD) reports "00 00 00 20h" .... set bit for Surprise Down Error. Though we can still continue to upload firmware to the chip. When loading xhci_pci.ko driver, I am consistently seeing "Unhandled fault: imprecise external abort (0x1406) at xxxxxxxxx" while in xhci_gen_setup(); adding debug messages somehow shows that the xhci->cap_regs == NULL thus the assignment "xhci->cap_regs = hcd->regs;" fails. Though once I saw it moved forward till " xhci_zero_64b_regs(xhci);" and died. Not sure if the above is because of some kernel bug or hardware issue. Didn't debugged it yet from the calling function as this is weird that xhci->cap_regs is NULL (can it be null if there is some hardware communication error before xhci_gen_setup call? I will also look at the addresses closer as you mentioned to see if its CPU memory access or MMIO. At this moment I don't have access to hardware; left it with the hardware designer to verify/debug some hardware clocks. > > Tried to disable DMA from kernel configuration but still same result. > > From hardware side verified the RESET pins for PEX8605 and uPD720202 > > chips but no change. > > > > Also wanted to read PCIe switch registers using I2C interface but have > > to figure-out how to do that (saw some patches email from Rajat Jain > > from 2014 but seems like can't find the patch attachment anywhere on > > Google). > > > > The kernel log is below.
