The following out of memory errors are seen on kexec reboot from the optee core. [ 0.368428] tee_bnxt_fw optee-clnt0: tee_shm_alloc failed [ 0.368461] tee_bnxt_fw: probe of optee-clnt0 failed with error -22 tee_shm_release() is not invoked on dma shm buffer. Implement .shutdown() in optee core as well as bnxt firmware driver to handle the release of the buffers correctly. More info: https://github.com/OP-TEE/optee_os/issues/3637
Jens,
Could you please take sometime out and review the series.
Thanks.
