CentOS/Kernel 3.18.4/Thunderbolt2

CentOS/Kernel 3.18.4/Thunderbolt2

[-- Attachment #1: Type: text/plain, Size: 1606 bytes --]

My company recently purchased and installed a new SuperMicro server with a Thunderbolt 2 (Falcon Ridge) card installed, specifically an AOC-TBT-DSL5320. I then installed CentOS 6, and, since to my understanding thunderbolt support is only in more recent kernels, I went ahead and upgraded the kernel to version 3.18.4 from ElRepo. However, I have not seen any indication yet that Thunderbolt is working - although I may just not be looking in the right place. Over on Google+ Greg Kroah-Hartman indicated that I need the PCI hot plug controller driver enabled, and Matthew Garrett indicated that I specifically need the ACPI PCI hotplug driver rather than the native PCIe hotplug driver. To check, I ran the following command:

egrep -i HOTPLUG /boot/config-3.18.4-1.el6.elrepo.x86_64

Which returned the following potentially relevant results:

CONFIG_ACPI_HOTPLUG_CPU=y
CONFIG_ACPI_HOTPLUG_MEMORY=y
CONFIG_HOTPLUG_PCI_PCIE=y
CONFIG_HOTPLUG_PCI=y

but also the following:

# CONFIG_HOTPLUG_PCI_ACPI is not set
# CONFIG_HOTPLUG_PCI_CPCI is not set 

So perhaps that's the entire problem - that CONFIG_HOTPLUG_PCI_ACPI is not set? If so, what's going to be the easiest solution? I'm willing to try recompiling the kernel, if someone could point me to a good guide, but I haven't done so before (at least, not on Linux. I've re-compiled the kernel on OpenBSD many times).

Yep, if you need the ACPI PCI hotplug driver, CONFIG_HOTPLUG_PCI_ACPI
should be enabled.  I think you should be able to use "make
menuconfig" to enable it at:

  Bus options
    Support for PCI Hotplug
      ACPI PCI Hotplug driver

I'm not  RedHat/CentOS person, so I don't know the distro details, but
I would try "make install" as a starting point.

Well, I went ahead and downloaded the 3.18.4 source, copied my current config, ran make menuconfig, and enabled that option. Then I ran make rpm, which gave me a RPM that I installed and was able to boot from. However, while I do see the ACPI PCI Hotplug driver loading in the DMESG, I still don't see any indication of the thunderbolt controller or the drive I plugged in.

Is there any chance I'm just being stupid here? That things ARE working, but are identified differently than I am expecting, so I don't see them?

Not necessarily.  Is this a plug-in controller or on the mobo?  If the latter, does your system BIOS show any Thunderbolt security options, and if so, what is it set to?

Plug in controller that came with the motherboard, specifically an AOC-TBT-DSL5320. Plugs into PCI slot 6 and has a cable running to the GPIO headers on the motherboard as well. It does have a section in the bios with a number of settings, such as enabled and whether or not to ignore the Option ROM, but I don't see anything about security there.
