Martyn, Do you know why ge_imp3a.c has 0x9000 as the 'primary' PCIe bus on the board? - k

Hi Kumar, Sorry, missed your mail. At a quick guess it's because that's the interface that is used for the on-board PCI devices.

What PCI devices are on-board? Does the board have any PCIe-ISA bridges? [ if you can generate an lspci dump, that might answer some of these = questions ] thanks - k=

Just SATA.
Does the board have any PCIe-ISA bridges?
No, though SERDES Port 1 is connected to a PCie-PCI non-transparent bridge to a PCI backplane.

Sorry, I don't have easy access to a board at the moment. Martyn -- Martyn Welch (Lead Software Engineer) | Registered in England and Wales GE Intelligent Platforms | (3828642) at 100 Barbirolli Square T +44(0)1327322748 | Manchester, M2 3AB E martyn.welch@ge.com | VAT:GB 927559189
