Subject: [PATCH v2 0/2] remoteproc: core: fix issue for multi-instance
Date: Mon, 28 Mar 2022 10:20:10 +0800 [thread overview]
Message-ID: <1648434012-16655-1-git-send-email-shengjiu.wang@nxp.com> (raw)
Use the rproc->power reference count to handle the multi-instance
case, move the state checking for 'stop' and 'detach' under
mutex protection, and remove state checking for 'start'.
Shengjiu Wang (2):
remoteproc: core: Remove state checking before calling rproc_boot()
remoteproc: core: Move state checking to remoteproc_core
changes in v2:
- drop 'remoteproc: core: check rproc->power value before decreasing it'
- refine 'remoteproc: core: Remove state checking before changing state'
split it to two new patches.
