It is often desireable to boot a remote processor with different firmware files, depending on the needs of the system at a particular time. This series adds a sysfs interface to the remoteproc core, exposing interfaces to manipulate the remote processor. One interface is the "state" file which performs the same function as the one in debugfs (which is removed later in the series). The other is a "firmware" file which allows retrieval of the name of the running firmware, and allows a new firmware to be loaded when written, as long as the remote processor is currently stopped. Some groundwork must be laid first, changing the storage mechanism of the firmware name such that it can be rewritten easily and then providing an accessor function to facilitate changing the loaded firmware. That is then wired up to the new sysfs interface. This series is based on v4.8 Matt Redfearn (4): remoteproc: Use fixed length field for firmware name remoteproc: Introduce rproc_change_firmware remoteproc: Add a sysfs interface for firmware and state remoteproc: debugfs: Remove state entry which is duplicated is sysfs Documentation/ABI/testing/sysfs-class-remoteproc | 50 +++++++++ drivers/remoteproc/Makefile | 1 + drivers/remoteproc/remoteproc_core.c | 129 ++++++++++++++++++---- drivers/remoteproc/remoteproc_debugfs.c | 71 ------------ drivers/remoteproc/remoteproc_internal.h | 6 ++ drivers/remoteproc/remoteproc_sysfs.c | 132 +++++++++++++++++++++++ include/linux/remoteproc.h | 4 +- 7 files changed, 299 insertions(+), 94 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-class-remoteproc create mode 100644 drivers/remoteproc/remoteproc_sysfs.c -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-remoteproc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
