To further facilitate troubleshooting, an optional build ID is introduced in the response to the OPTEE_SMC_CALL_GET_OS_REVISION request. Upstream OP-TEE uses this field to report its Git SHA1 since commit 29cff5cf09aa ("core: GET_OS_REVISION: return SHA1 of current Git commit"). Typical boot log (>> is introduced by this patchset): optee: probing for conduit method from DT. >> optee: revision 2.6 (947cfeec) optee: initialized driver ...or, if the build ID is not set by the TEE or set to zero: optee: probing for conduit method from DT. >> optee: revision 2.6 optee: initialized driver Jerome Forissier (2): tee: optee: GET_OS_REVISION: document a2 as a build identifier tee: optee: report OP-TEE revision information drivers/tee/optee/core.c | 23 +++++++++++++++++++++++ drivers/tee/optee/optee_smc.h | 10 +++++++++- 2 files changed, 32 insertions(+), 1 deletion(-) -- 2.7.4
