[Bug]tpm initialization fails on x86

[yunyings]

When trying to test TPM with Ubuntu 16.04 on Intel x86_64 platform, there's tpm initialization failure found in kernel log:
root@SKLU1-leg:~# dmesg | grep -i tpm
[ 0.000000] ACPI: SSDT 0x000000007FFE4000 0004D6 (v02 Intel_ Tpm2Tabl 00001000 INTL 20141107)
[ 0.000000] ACPI: TPM2 0x000000007FFE2000 000034 (v03 00000000 00000000)
[ 2.532245] ima: No TPM chip found, activating TPM-bypass!
[ 3.489431] tpm_crb MSFT0101:00: can't request region for resource [mem 0xfed40040-0xfed4103f]
[ 3.489437] tpm_crb: probe of MSFT0101:00 failed with error -16

which leads to tpm device missing under /dev:
root@SKLU1-leg:~# ls -l /dev/tpm*
ls: cannot access '/dev/tpm*': No such file or directory

This error has been fixed with patch below, but not yet merged to upstream kernel:
http://git.infradead.org/users/jjs/linux-tpmdd.git/commit/0af6e0a2da2e4fedaa2743333da438d3b879192b

Patch 0af6e0a has dependency to this patch:
http://git.infradead.org/users/jjs/linux-tpmdd.git/commit/3f944075e75e28c9cf1af8f82798398b
So 0af6e0a has to be applied upon 3f94407, otherwise patch apply fails.

I've verified with kernel 4.7-rc4 that above 2 patches can fix this TPM issue.
So please Ubuntu team help on backporting these 2 patches into the kernel of their next release.

PS, below are some information about Ubuntu & kernel & cpu info on my test server, for your reference:

Yakkety will pick this up naturally in v4.8

[Kamal Mostafa (kamalmostafa)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I'm running Ubuntu 16.04.2 with kernel 4.8.0-41-generic on ASUS ux330ua (Skylake i7-6500). The problem is still there. So the fix doesn't seem to be included in kernel 4.8.*

dmesg | grep -i tpm

[Tomas Winkler (tomas-winkler)]

This is a BIOS issue can you please attach dmidecode of your platform, I'd like to know more detailed platform and bios information.
Also please add the while dmesg and cat /proc/iomem
Thanks

alpha1z: Please start a new bug as I think you have a different issue then the original bug report.

NUK SKL-H BIOS version 0045 and later should fix this issue.
