remoteproc: Don't bother checking the return value of debugfs_create*

2022-04-11T16:04:40+00:00

DebugFS APIs are designed to return only the error pointers and not NULL in the case of failure. So these return pointers are safe to be passed on to the successive debugfs_create* APIs. Therefore, let's just get rid of the checks.

remoteproc: Fix count check in rproc_coredump_write()

2022-02-19T00:15:05+00:00

Check count for 0, to avoid a potential underflow. Make the check the same as the one in rproc_recovery_write().

remoteproc: add is_iomem to da_to_va

2021-03-11T18:02:41+00:00

Introduce an extra parameter is_iomem to da_to_va, then the caller could take the memory as normal memory or io mapped memory.

remoteproc: Change default dump configuration to "disabled"

2020-10-14T00:20:54+00:00

Currently "default" configuration option means coredumps are enabled. To avoid confusion rename the "default" configuration option to "enabled" and disable collection of dumps by default as doing so makes sense for production devices.

remoteproc: Fixup coredump debugfs disable request

Fix the discrepancy observed between accepted input and read back value while disabling remoteproc coredump through the coredump debugfs entry.

remoteproc: Add coredump debugfs entry

2020-07-21T21:04:12+00:00

Add coredump debugfs entry to configure the type of dump that will be collected during recovery. User can select between default or inline coredump functionality. Also coredump collection can be disabled through this interface. This functionality can be configured differently for different remote processors.

Don't bother checking the remoteproc state before calling rproc_trigger_recovery() because that function will verify the state, and the state can only be safely checked while holding the mutex anyway.

remoteproc: Use size_t instead of int for rproc_mem_entry len

2020-03-26T05:29:39+00:00

Now that rproc_da_to_va uses a size_t for length, use a size_t for len field of rproc_mem_entry. Function used to create such structures now takes a size_t instead of int to allow full size range to be handled.
