Description Matt Domsch 2009-10-21 16:09:07 UTC 
Created attachment 365546 [details]
0001-tpm-autoload-tpm_tis-based-on-system-PnP-IDs.patch

Description of problem:
The tpm_tis driver already has a list of supported pnp_device_ids.
This patch simply exports that list as a MODULE_DEVICE_TABLE() so that
the module autoloader will discover and load the module at boottime.

This causes the tpm_tis driver to autoload on Dell 11G servers when the TPM is enabled in BIOS SETUP.

This has been submitted to lkml for inclusion in mainline.

This is also related to
https://bugzilla.redhat.com/show_bug.cgi?id=461716
which teaches rngd to use the TPM.

Thanks for the test report! In the future, it'd be greatly appreciated if you could also add 'Dell' to the Verified field along with your comment to indicate Dell has completed verification testing for this request. I've taken care of it this time. Thanks!
