remoteproc: core: Register the character device interface (2020-08-04 20:17:08 -0700)
----------------------------------------------------------------
remoteproc updates for v5.9
This introduces a new "detached" state for remote processors that are
deemed to be running at the time Linux boots and the infrastructure for
"attaching" to these. It then introduces the support for performing this
operation for the STM32 platform.
The coredump functionality is moved out from the core file and gains
support for an optional mode where the recovery phase awaits the
notification from devcoredump that the dump should be released. This
allows userspace to grab the coredump in scenarios where vmalloc space
is too low for creating a complete copy of the coredump before handing
this to devcoredump.
A new character device based interface is introduced to allow tying the
stoppage of a remote processor to the termination of a user space
process. This is useful in situations when such process provides crucial
resources/operations for the firmware running on the remote processor.
The Texas Instrument K3 driver gains support for the C66x and C71x DSPs.
Qualcomm remoteprocs gains support for stashing relocation information
in IMEM, to aid post mortem debugging and the crash notification
mechanism is generalized to be reusable in cases where loosely coupled
drivers needs to know about the status of a remote processor. One such
example is the IPA hardware block, which is jointly owned with the
modem and migrated to this improved interface.
It also introduces a number of bug fixes and debug improvements for the
Qualcomm modem remoteproc driver.
And it cleans up the inconsistent interface for remoteproc drivers to
implement power management.
