| Data Fields | ||
|---|---|---|
| dt_clock_t | clock[kDtKeymgrDpeClockCount] | Clock signal connected to each clock port. |
| top_darjeeling_alert_id_t | first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler. |
| top_darjeeling_plic_irq_id_t | first_irq |
PLIC ID of the first IRQ of this instance. This can be |
| dt_instance_id_t | inst_id | Instance ID. |
| uint32_t | mem_addr[kDtKeymgrDpeMemoryCount] | Base address of each memory. |
| uint32_t | mem_size[kDtKeymgrDpeMemoryCount] | Size in bytes of each memory. |
| uint32_t | reg_addr[kDtKeymgrDpeRegBlockCount] | Base address of each register block. |
| dt_reset_t | reset[kDtKeymgrDpeResetCount] | Reset signal connected to each reset port. |
| #define TRY_GET_DT | ( | dt, | |
| default ) |
Return a pointer to the dt_keymgr_dpe_desc_t structure of the requested dt if it's a valid index.
Otherwise, this macro will return (i.e. exit the function) with the provided default value.

| dt_keymgr_dpe_alert_t dt_keymgr_dpe_alert_from_alert_id | ( | dt_keymgr_dpe_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local keymgr_dpe alert type.
| dt | Instance of keymgr_dpe. |
| alert | A global alert ID that belongs to this instance. |
kDtKeymgrDpeAlertCount.Note: This function assumes that the global alert ID belongs to the instance of keymgr_dpe passed in parameter. In other words, it must be the case that dt_keymgr_dpe_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtKeymgrDpeAlertCount.

| dt_alert_id_t dt_keymgr_dpe_alert_to_alert_id | ( | dt_keymgr_dpe_t | dt, |
| dt_keymgr_dpe_alert_t | alert ) |
Get the alert ID of a keymgr_dpe alert for a given instance.
Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.
| dt | Instance of keymgr_dpe. |
| alert | A keymgr_dpe alert. |
Definition at line 131 of file dt_keymgr_dpe.c.
Get the clock signal connected to a clock port of an instance.
| dt | Instance of keymgr_dpe. |
| clk | Clock port. |
Definition at line 149 of file dt_keymgr_dpe.c.
| dt_keymgr_dpe_t dt_keymgr_dpe_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the keymgr_dpe instance from an instance ID.
For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.
| inst_id | Instance ID. |
Note: This function only makes sense if the instance ID has device type keymgr_dpe, otherwise the returned value is unspecified.
Definition at line 73 of file dt_keymgr_dpe.c.
| dt_instance_id_t dt_keymgr_dpe_instance_id | ( | dt_keymgr_dpe_t | dt | ) |
Get the instance ID of an instance.
| dt | Instance of keymgr_dpe. |
Definition at line 80 of file dt_keymgr_dpe.c.
| dt_keymgr_dpe_irq_t dt_keymgr_dpe_irq_from_plic_id | ( | dt_keymgr_dpe_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local keymgr_dpe IRQ type.
| dt | Instance of keymgr_dpe. |
| irq | A PLIC ID that belongs to this instance. |
kDtKeymgrDpeIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of keymgr_dpe passed in parameter. In other words, it must be the case that dt_keymgr_dpe_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtKeymgrDpeIrqCount.
Definition at line 116 of file dt_keymgr_dpe.c.
| dt_plic_irq_id_t dt_keymgr_dpe_irq_to_plic_id | ( | dt_keymgr_dpe_t | dt, |
| dt_keymgr_dpe_irq_t | irq ) |
Get the PLIC ID of a keymgr_dpe IRQ for a given instance.
If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.
| dt | Instance of keymgr_dpe. |
| irq | A keymgr_dpe IRQ. |
Definition at line 106 of file dt_keymgr_dpe.c.
| uint32_t dt_keymgr_dpe_memory_base | ( | dt_keymgr_dpe_t | dt, |
| dt_keymgr_dpe_memory_t | mem ) |
Get the base address of a memory.
| dt | Instance of keymgr_dpe. |
| mem | The memory requested. |
Definition at line 92 of file dt_keymgr_dpe.c.
| uint32_t dt_keymgr_dpe_memory_size | ( | dt_keymgr_dpe_t | dt, |
| dt_keymgr_dpe_memory_t | mem ) |
Get the size of a memory.
| dt | Instance of keymgr_dpe. |
| mem | The memory requested. |
Definition at line 99 of file dt_keymgr_dpe.c.
| uint32_t dt_keymgr_dpe_reg_block | ( | dt_keymgr_dpe_t | dt, |
| dt_keymgr_dpe_reg_block_t | reg_block ) |
Get the register base address of an instance.
| dt | Instance of keymgr_dpe. |
| reg_block | The register block requested. |
Definition at line 85 of file dt_keymgr_dpe.c.
Get the reset signal connected to a reset port of an instance.
| dt | Instance of keymgr_dpe. |
| rst | Reset port. |
