Firmware-debug provides debugfs interface to all APIs. Debugfs can be used to call firmware APIs with required parameters. Usage: * Calling firmware API through debugfs: # echo "<api-name> <arg1> .. <argn>" > /sys/kernel/debug/zynqmp-firmware/pm * Read output of last called firmware API: # cat /sys/kernel/debug/zynqmp-firmware/pm Refer ug1200 for more information on these APIs: * https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf Below are supported debugfs APIs: * PM_REQUEST_SUSPEND * PM_SELF_SUSPEND * PM_FORCE_POWERDOWN * PM_ABORT_SUSPEND * PM_REQUEST_WAKEUP * PM_SET_WAKEUP_SOURCE * PM_SYSTEM_SHUTDOWN * PM_REQUEST_NODE * PM_RELEASE_NODE * PM_SET_REQUIREMENT * PM_SET_MAX_LATENCY * PM_GET_API_VERSION * PM_SET_CONFIGURATION * PM_GET_NODE_STATUS * PM_GET_OPERATING_CHARACTERISTIC * PM_REGISTER_NOTIFIER * PM_RESET_ASSERT * PM_RESET_GET_STATUS * PM_GET_CHIPID * PM_PINCTRL_GET_FUNCTION * PM_PINCTRL_SET_FUNCTION * PM_PINCTRL_CONFIG_PARAM_GET * PM_PINCTRL_CONFIG_PARAM_SET * PM_IOCTL * PM_CLOCK_ENABLE * PM_CLOCK_DISABLE * PM_CLOCK_GETSTATE * PM_CLOCK_SETDIVIDER * PM_CLOCK_GETDIVIDER * PM_CLOCK_SETRATE * PM_CLOCK_GETRATE * PM_CLOCK_SETPARENT * PM_CLOCK_GETPARENT * PM_QUERY_DATA Signed-off-by: Jolly Shah <jollys@xxxxxxxxxx> Signed-off-by: Rajan Vaja <rajanv@xxxxxxxxxx> --- drivers/firmware/xilinx/zynqmp/Kconfig | 7 + drivers/firmware/xilinx/zynqmp/Makefile | 1 + drivers/firmware/xilinx/zynqmp/firmware-debug.c | 482 +++++++++++++++++++++ drivers/firmware/xilinx/zynqmp/firmware.c | 7 +- .../linux/firmware/xilinx/zynqmp/firmware-debug.h | 22 + 5 files changed, 518 insertions(+), 1 deletion(-) create mode 100644 drivers/firmware/xilinx/zynqmp/firmware-debug.c create mode 100644 include/linux/firmware/xilinx/zynqmp/firmware-debug.h diff --git a/drivers/firmware/xilinx/zynqmp/Kconfig b/drivers/firmware/xilinx/zynqmp/Kconfig index 5054b80..5c22aba 100644 --- a/drivers/firmware/xilinx/zynqmp/Kconfig +++ b/drivers/firmware/xilinx/zynqmp/Kconfig @@ -13,4 +13,11 @@ config ZYNQMP_FIRMWARE Say yes to enable ZynqMP firmware interface driver.
