Re: [Tee-dev] Optee: out of memory failures in due to tee_shm_free()

...

I have been seeing out of memory failures due to tee_shm_free() on

kexec path. This issue in discussed in length at:

link: https://github.com/OP-TEE/optee_os/issues/3637 Driver: drivers/firmware/broadcom/tee_bnxt_fw.c

I have tried various experiments to try and debug this issue but

haven't found a fix. All I have manged is to delay the occurrence of the issue.

Any pointers would be helpful.

I guess you've seen that optee_disable_shm_cache() must somehow be called in the kexec flow. I don't know how to do that though.

Thank you Jens. I don't have much idea either, but will try out some experiments.

Thanks.
