Hi,

Is there PCIe-3.0 driver is available in linux kernel?

PCI-E 3.0 (8 GT/s) has been supported by Linux since 2010.

Thanks for your replay, I saw PCIE_SPEED_8_0GT is defined in following files(linux kernel v3.1)

include/linux/pci.h, line 213
drivers/pci/probe.c, line 436
drivers/pci/slot.c, line 75

patch is here: http://tima-sls.imag.fr/viewgit/gene...2a4ef2f31f571a

but it says that: "PCI: Add support for reporting PCIe 3.0 speeds", is that enough for entire PCIe-3.0 support?

Yes; there's no other change required.
