RPMON is a driver framework. It supports remote processor monitor from user level. The basic components are a character device with sysfs interfaces for user space communication and different kinds of message drivers introduced modularly, which are used to communicate with remote processors. As for user space, one can get notifications of different events of remote processors, like their registrations, through standard file read operation of the file descriptors related to the exported character devices. Actions can also be taken into account via standard write operations to the devices. Besides, the sysfs class attributes could be accessed conveniently. Message drivers act as engines to communicate with remote processors. Currently RPMON_QMI is available which uses QMI infrastructures on Qualcomm SoC Platforms. RPMON_QMI implements a kind of communication routine for RPMON to communicate with remote processors through QMI infrastructure. RPMON_QMI itself is designed as a modular framework that would introduce different kind of message sets which are binding to different services. RPMON_QMI creates a device of rpmon_device type for each remote processor endpoint. All the endpoint devices share an unique set of QMI suite. RPMON_QMI_MSG_V01 implements a RPMON_QMI message set for connection check. RPMON_QMI defines its message types modularly. Each rpmon service binds to a message set and introduced as a module. This version 1.0 message set could be used for connection checking of remote processors. RPMON_QMI messages depend on QCOM_QMI_HELPERS and should be updated together with QMI related modules. Changes since v1: - Addressed review comments from Randy Changes since v2: - Added Cc list - Commit log typo fixing - Use the ARRAY_SIZE instead of calculations of multiple sizeof() - Use micros for qmi message tly_type fields Wang Wenhu (3): driver: rpmon: new driver Remote Processor Monitor driver: rpmon: qmi message version 01 driver: rpmon: add rpmon_qmi driver drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/rpmon/Kconfig | 54 ++++ drivers/rpmon/Makefile | 3 + drivers/rpmon/rpmon.c | 506 +++++++++++++++++++++++++++++++ drivers/rpmon/rpmon_qmi.c | 431 ++++++++++++++++++++++++++ drivers/rpmon/rpmon_qmi.h | 76 +++++ drivers/rpmon/rpmon_qmi_msg_v1.c | 258 ++++++++++++++++ include/linux/rpmon.h | 68 +++++ 9 files changed, 1399 insertions(+) create mode 100644 drivers/rpmon/Kconfig create mode 100644 drivers/rpmon/Makefile create mode 100644 drivers/rpmon/rpmon.c create mode 100644 drivers/rpmon/rpmon_qmi.c create mode 100644 drivers/rpmon/rpmon_qmi.h create mode 100644 drivers/rpmon/rpmon_qmi_msg_v1.c create mode 100644 include/linux/rpmon.h -- 2.17.1
