linux-toradex.git/drivers/rpmsg, branch v4.18-rc4 Linux kernel for Apalis and Colibri modules rpmsg: smd: do not use mananged resources for endpoints and channels 2018-06-04T19:35:03+00:00 Srinivas Kandagatla srinivas.kandagatla@linaro.org 2018-06-04T09:39:01+00:00 4a2e84c6ed85434ce7843e4844b4d3263f7e233b All the managed resources would be freed by the time release function is invoked. Handling such memory in qcom_smd_edge_release() would do bad things. Found this issue while testing Audio usecase where the dsp is started up and shutdown in a loop. This patch fixes this issue by using simple kzalloc for allocating channel->name and channel which is then freed in qcom_smd_edge_release(). Without this patch restarting a remoteproc would crash the system.

All the managed resources would be freed by the time release function
is invoked. Handling such memory in qcom_smd_edge_release() would do
bad things.

Found this issue while testing Audio usecase where the dsp is started up
and shutdown in a loop.

This patch fixes this issue by using simple kzalloc for allocating
channel->name and channel which is then freed in qcom_smd_edge_release().

Without this patch restarting a remoteproc would crash the system.
