Data Structure Documentation

◆ dt_desc_soc_proxy

struct dt_desc_soc_proxy

Description of instances.

Definition at line 19 of file dt_soc_proxy.c.

Data Fields
uint32_t base_addr[kDtSocProxyRegBlockCount] Base address of each register block.
dt_clock_t clock[kDtSocProxyClockCount] 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 kDtPlicIrqIdNone if the block is not connected to the PLIC.

dt_instance_id_t inst_id Instance ID.
dt_periph_io_t periph_io[kDtSocProxyPeriphIoCount] Description of each peripheral I/O.
dt_reset_t reset[kDtSocProxyResetCount] Reset signal connected to each reset port.

Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT ( dt,
default )
Value:
({ if ((dt) < (dt_soc_proxy_t)0 || (dt) >= kDtSocProxyCount) return (default); &soc_proxy_desc[dt]; })

Return a pointer to the dt_soc_proxy_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.

Function Documentation

◆ dt_soc_proxy_alert_from_alert_id()

dt_soc_proxy_alert_t dt_soc_proxy_alert_from_alert_id ( dt_soc_proxy_t dt,
dt_alert_id_t alert )

Convert a global alert ID to a local soc_proxy alert type.

Parameters
dtInstance of soc_proxy.
alertA global alert ID that belongs to this instance.
Returns
The soc_proxy alert, or kDtSocProxyAlertCount.

Note: This function assumes that the global alert ID belongs to the instance of soc_proxy passed in parameter. In other words, it must be the case that dt_soc_proxy_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtSocProxyAlertCount.

Definition at line 377 of file dt_soc_proxy.c.

◆ dt_soc_proxy_alert_to_alert_id()

dt_alert_id_t dt_soc_proxy_alert_to_alert_id ( dt_soc_proxy_t dt,
dt_soc_proxy_alert_t alert )

Get the alert ID of a soc_proxy 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.

Parameters
dtInstance of soc_proxy.
alertA soc_proxy alert.
Returns
The Alert Handler alert ID of the alert of this instance.

Definition at line 371 of file dt_soc_proxy.c.

◆ dt_soc_proxy_clock()

Get the clock signal connected to a clock port of an instance.

Parameters
dtInstance of soc_proxy.
clkClock port.
Returns
Clock signal.

Definition at line 395 of file dt_soc_proxy.c.

◆ dt_soc_proxy_from_instance_id()

dt_soc_proxy_t dt_soc_proxy_from_instance_id ( dt_instance_id_t inst_id)

Get the soc_proxy instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters
inst_idInstance ID.
Returns
A soc_proxy instance.

Note: This function only makes sense if the instance ID has device type soc_proxy, otherwise the returned value is unspecified.

Definition at line 327 of file dt_soc_proxy.c.

◆ dt_soc_proxy_instance_id()

dt_instance_id_t dt_soc_proxy_instance_id ( dt_soc_proxy_t dt)

Get the instance ID of an instance.

Parameters
dtInstance of soc_proxy.
Returns
The instance ID of that instance.

Definition at line 334 of file dt_soc_proxy.c.

◆ dt_soc_proxy_irq_from_plic_id()

dt_soc_proxy_irq_t dt_soc_proxy_irq_from_plic_id ( dt_soc_proxy_t dt,
dt_plic_irq_id_t irq )

Convert a global IRQ ID to a local soc_proxy IRQ type.

Parameters
dtInstance of soc_proxy.
irqA PLIC ID that belongs to this instance.
Returns
The soc_proxy IRQ, or kDtSocProxyIrqCount.

Note: This function assumes that the PLIC ID belongs to the instance of soc_proxy passed in parameter. In other words, it must be the case that dt_soc_proxy_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtSocProxyIrqCount.

Definition at line 356 of file dt_soc_proxy.c.

◆ dt_soc_proxy_irq_to_plic_id()

dt_plic_irq_id_t dt_soc_proxy_irq_to_plic_id ( dt_soc_proxy_t dt,
dt_soc_proxy_irq_t irq )

Get the PLIC ID of a soc_proxy IRQ for a given instance.

If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.

Parameters
dtInstance of soc_proxy.
irqA soc_proxy IRQ.
Returns
The PLIC ID of the IRQ of this instance.

Definition at line 346 of file dt_soc_proxy.c.

◆ dt_soc_proxy_periph_io()

Get the peripheral I/O description of an instance.

Parameters
dtInstance of soc_proxy.
sigRequested peripheral I/O.
Returns
Description of the requested peripheral I/O for this instance.

Definition at line 388 of file dt_soc_proxy.c.

◆ dt_soc_proxy_reg_block()

Get the register base address of an instance.

Parameters
dtInstance of soc_proxy.
reg_blockThe register block requested.
Returns
The register base address of the requested block.

Definition at line 339 of file dt_soc_proxy.c.

◆ dt_soc_proxy_reset()

Get the reset signal connected to a reset port of an instance.

Parameters
dtInstance of soc_proxy.
rstReset port.
Returns
Reset signal.
