The following changes since commit b3a9e3b9622ae10064826dccb4f7a52bd88c7407: Linux 5.8-rc1 (2020-06-14 12:45:04 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc.git tags/rproc-v5.9 for you to fetch changes up to 62b8f9e99329c92286534d05dac9dc0a6e0ba0cf: 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. ---------------------------------------------------------------- Alex Elder (2): net: ipa: new
