Compare with the PCI configure registers that change between sleep/wake are the offset 0x2c~0x2f, which are the subsystem vendor ID and subsystem ID, these IDs can mainly be used for further identification of a device. If the chip in itself is a generic interface chip to a local (onboard) bus, it is often used in several completely different roles, and the driver must identify the actual device it is talking with. The subsystem identifiers are used to this aim.
Checking with the lspci, it should be the device, 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208M [GeForce GT 730M] [10de:1290] Not sure if the NVIDIA driver need to use these SVID,SID. It might need to do the function tests for this device to see if it work normal before sleep/after wake. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312559 Title: [Lenovo T540p] DevConfigDiffAfterS3 and DevConfigDiffAfterS4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwts/+bug/1312559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
