To enable this we introduce a new flag for the device creation ioctl that requests that the locality be prepended to every command. For applications to check which flags the driver supports, we add a new ioctl that returns a bitmask of supported flags. v2->v3: - addressed Jarkko's comments v1->v2: - fixed return value from function in patch 3/3 Stefan Berger (3): tpm: vtpm_proxy: Implement new ioctl to get supported flags tpm: vtpm_proxy: Implement request_locality function. tpm: vtpm_proxy: Add flag for ioctl to request locality prepended to command drivers/char/tpm/tpm_vtpm_proxy.c | 53 ++++++++++++++++++++++++++++++++++++--- include/uapi/linux/vtpm_proxy.h | 17 +++++++++++-- 2 files changed, 64 insertions(+), 6 deletions(-) -- 2.4.3
