Intel C620 chipset in Maestro SGM

[Dayaana]

Hello everyone!

We have encountered an issue with unavailability of various SGM members. In messages files we have noticed the following messages:

kernel:pci 0000:00:11.0: device has non-compliant BARs; disabling IO/MEM

The lspci output indicates that this is an Intel C620 chipset:
00:11.0 Unassigned class [ff00]: Intel Corporation C620 Series Chipset Family MR OM 0 (rev 09)

Please tell me how important is this chipset in the checkpoint hardware? Does anyone know about its functions in the system?

I will be grateful for any help!

What SGM hardware/software versions are you using?

Thank you very much for your answer! We have 16600 and R81.20.

I think that chipset is a core part of the system, though I'm not sure if that line in the messages file means anything too much. Probably best to get a TAC case going if you have SGMs becoming unavailable. Make sure to upload the output of 'hcp -r all -m all' and any recent core dumps that might be on any of the SGMs to the case.

Thank you very much for the information! Do you have any suggestions about the functions of the Intel C620 chipset in the system?

I think it's the main chipset that supports the processor, but I don't know for sure. It's not a Check Point part, it's a standard Intel chipset.

Thank you very much!

The chipset is critical to the system. It provides the low-speed I/O such as the SATA channels and USB ports.

That message is from a Linux kernel feature added in 2016 to support better indirection for copying data between main memory and a PCIe device's memory. It's mostly used for variable-size copies to video cards. It isn't relevant for use as a firewall.
