Subject: [PATCH v6 00/11] Multi-instance vTPM driver
Date: Wed, 9 Mar 2016 12:39:19 -0500 [thread overview]
Message-ID: <1457545170-30120-1-git-send-email-stefanb@linux.vnet.ibm.com> (raw)
The following series of patches implements a multi-instance vTPM driver
that can dynamically create TPM 'server' and client device pairs.
Using an ioctl on the provided /dev/vtpmx, a client-side vTPM device
and a server side file descriptor is created. The file descriptor must
be passed to a TPM emulator. The device driver will initialize the
emulated TPM using TPM 1.2 or TPM 2 startup commands and it will read
the command durations from the device in case of a TPM 1.2. The choice
of emulated TPM device (1.2 or 2) must be provided with a flag in
the ioctl.
The driver is based on James Morris's 'next' branch and uses several
recently posted patches from Jason and Jarkko.
Stefan
v5->v6:
- Adapted errno's for unsupported flags and ioctls following Jason's comments
v4->v5:
- Introduced different error codes for unsupported flags and ioctls
- Added documentation patch
Jason Gunthorpe (4):
tpm: Get rid of chip->pdev
tpm: Get rid of devname
tpm: Provide strong locking for device removal
tpm: Split out the devm stuff from tpmm_chip_alloc
Stefan Berger (7):
tpm: Get rid of module locking
tpm: Replace device number bitmap with IDR
tpm: Introduce TPM_CHIP_FLAG_VIRTUAL
tpm: Driver for supporting multiple emulated TPMs
tpm: Initialize TPM and get durations and timeouts
tpm: Add documentation for the tpm_vtpm device driver
A test program for vTPM device creation
