I have a new laptop, and have everything working except the Communication controller: Intel Corporation Cougar Point HECI Controller.
Does anyone know what linux kernel configuration command to activate the Intel Corporation Cougar Point HECI Controller?

Sorry if this is a dumb question, but what functions are
missing from your laptop?

The Communication controller: Intel Corporation Cougar Point HECI Controller is the last device that doesn't have a driver.

Everything else seams to work, but I haven't tested the USB 3.0 (Don't have a USB 3.0 device), VGA, or HDMI (Don't have a HDMI device).
But, I would really like to get the HECI Controller to work under Linux to be able to use the Active Management Technology.

Thanks.

Don't know why, but the "PostReply" button isn't working.

But, lshw does have a USB 3.0 device using the xhci driver.
No, I don't have anything that is USB 3.0.

for usb 3.0 you need to enable xhci.

is there a way to test that device?

Not to sound alarmist, but at

[url]http://www.thinkwiki.org/wiki/Intel_Active_Management_Technology_(AMT)[/url]

I find this remark:
Quote:
The Linux heci driver to support iAMT was part of the staging tree as of the 2.6.30 kernel, but removed in 2.6.32 at the request of Intel as they have indicated having no further interest in it and have abandoned it.

Intel OpenAMT project website (abandoned)


I'd be interested to hear if this is correct or there is any news about it ...


P.S. Why isn't the URL tag working??

Still in the staging tree:
config INTEL_MEI
tristate "Intel Management Engine Interface (Intel MEI)"
depends on X86 && PCI && EXPERIMENTAL && WATCHDOG_CORE

Can anyone explain what this thing actually does? I have one of these, but I never bothered figuring out how do to something with it, but now I'd like to know what I'm potentially missing.

I just obtain dell alienware m17 r3 a I am just in process of hw drivers examining. I also have this device without any driver loaded.

Code:

# lspci -k -nn
...
00:16.0 Communication controller [0780]: Intel Corporation Cougar Point HECI Controller #1 [8086:1c3a] (rev 04)
        Subsystem: Dell Device [1028:0490]
...


I didn't take a look into kernel by myself, strange is that if it's abadoned by Intel why it still appears in new machines...

A particular driver was abandoned by them, that's all. But there is a new one in the kernel. I see it being loaded all the time when people on various forums post their lsmod output.

aha, I see now...
I finally found there is new "mei" driver under Device drivers -> Staging drivers ->Intel Management Engine Interface (Intel MEI). I select it to compile as built in and the result is:
Code:

00:16.0 Communication controller [0780]: Intel Corporation Cougar Point HECI Controller #1 [8086:1c3a] (rev 04)
        Subsystem: Dell Device [1028:0490]
        Kernel driver in use: mei


thanks
