Typedefs

typedef int(* emul_espi_api_set_vw) (const struct emul *target, enum espi_vwire_signal vw, uint8_t level)
 Passes eSPI virtual wires set request (virtual wire packet) to the emulator.
 
typedef int(* emul_espi_api_get_vw) (const struct emul *target, enum espi_vwire_signal vw, uint8_t *level)
 Passes eSPI virtual wires get request (virtual wire packet) to the emulator.
 
typedef struct espi_emul *(* emul_find_emul) (const struct device *dev, unsigned int chipsel)
 Find an emulator present on a eSPI bus.
 
typedef int(* emul_trigger_event) (const struct device *dev, struct espi_event *evt)
 Triggers an event on the emulator of eSPI controller side which causes calling specific callbacks.
 

Functions

int espi_emul_register (const struct device *dev, struct espi_emul *emul)
 Register an emulated device on the controller.
 
int emul_espi_host_send_vw (const struct device *espi_dev, enum espi_vwire_signal vw, uint8_t level)
 Sets the eSPI virtual wire on the host side, which will trigger a proper event(and callbacks) on the emulated eSPI controller.
 
int emul_espi_host_port80_write (const struct device *espi_dev, uint32_t data)
 Perform port80 write on the emulated host side, which will trigger a proper event(and callbacks) on the emulated eSPI controller.
