tpm: xen-tpmfront: fix missing declaration of xen_domain

2013-10-10T14:38:27+00:00

xen-tpmfront fails to build on arm64 with the following error:

drivers/char/tpm/xen-tpmfront.c: In function ‘xen_tpmfront_init’:
drivers/char/tpm/xen-tpmfront.c:422:2: error: implicit declaration of function ‘xen_domain’ [-Werror=implicit-function-declaration]

Add include of xen/xen.h to fix this.

 "Bug-fixes and one update to the kernel-paramters.txt documentation.

   - Fix PV spinlocks triggering jump_label code bug

     of memory
   - Add xen_nopvpsin parameter to the documentation"

tpm: xen-tpmfront: Remove the locality sysfs attribute

2013-09-24T20:15:15+00:00

Upon deeper review it was agreed to remove the driver-unique
'locality' sysfs attribute before it is present in a released
kernel.

The attribute was introduced in e2683957fb268c6b29316fd9e7191e13239a30a5
during the 3.12 merge window, so this patch needs to go in before
3.12 is released.

The hope is to have a well defined locality API that all the other
locality aware drivers can use, perhaps in 3.13.

tpm: xen-tpmfront: Fix default durations

2013-09-24T20:14:55+00:00

All the default durations were being set to 10 minutes which is
way too long for the timeouts. Normal values for the longest
duration are around 5 mins, and short duration ar around .5s.

Further, these are just the default, tpm_get_timeouts will set
them to values from the TPM (or throw an error).

Just remove them.

tpm: convert tpm_tis driver to use dev_pm_ops from legacy pm_ops

2013-09-11T22:58:16+00:00

Convert drivers/char/tpm/tpm_tis.c to use dev_pm_ops instead of legacy
pm_ops.  This patch depends on pnp driver bus ops change to invoke
pnp_driver dev_pm_ops.

drivers/xen-tpmfront: Fix compile issue with missing option.

2013-08-30T17:24:14+00:00

Randy reports:

x86_64:

drivers/built-in.o: In function `xen_tpmfront_init':
xen-tpmfront.c:(.init.text+0x257c): undefined reference to `xenbus_register_frontend'

This is nicely fixed by selecting the XenBus frontend module.

drivers/tpm: add xen tpmfront interface

2013-08-09T14:57:06+00:00

This is a complete rewrite of the Xen TPM frontend driver, taking
advantage of a simplified frontend/backend interface and adding support
for cancellation and timeouts.  The backend for this driver is provided
by a vTPM stub domain using the interface in Xen 4.3.

tpm/tpm_i2c_infineon: Remove unused header file

This driver does not use any module parameters anymore,
so the inclusion of the header file can be removed.

tpm: fix regression caused by section type conflict of tpm_dev_release() in ppc builds

2013-05-27T20:09:09+00:00

The 8119807 commit reintroduced a regression
(error: __ksymtab_tpm_dev_release causes a section type conflict) that was fixed by commit
cbb2ed4.
Fix it for good by adding the prototype to tpm.h so sparse doesn't
complain about it anymore.
