Data Structure Documentation

struct ifx_se_ppc_config_t

Data Fields
uint32_t	start_region	Starting peripheral region ID.
uint32_t	end_region	Ending peripheral region ID. To apply policy to a single peripheral region, assign the same value to start_region and endRegion
ifx_se_ppc_sec_attribute_t	sec_attribute	Security attribute.
ifx_se_ppc_secpriv_attribute_t	sec_priv_attribute	Secure Privilege attribute.
ifx_se_ppc_nspriv_attribute_t	ns_priv_attribute	Non-secure Privilege attribute.
uint32_t	pc_mask	PC mask.

PPC security attributes.

Enumerator
IFX_SE_PPC_SECURE	PPC region is Secure.
IFX_SE_PPC_NON_SECURE	PPC region is Non-secure.
IFX_SE_PPC_MAX	Maximum value to fix enum size.

PPC Non-secure privilege attributes.

Enumerator
IFX_SE_PPC_NON_SEC_PRIV	Privilege access to non-secure region.
IFX_SE_PPC_NON_SEC_NONPRIV	Privilege and non-privilege access to non-secure region
IFX_SE_PPC_NON_SEC_MAX	Maximum value to fix enum size.

PPC Secure privilege attributes.

Enumerator
IFX_SE_PPC_SEC_PRIV	Privilege access to secure region.
IFX_SE_PPC_SEC_NONPRIV	Privilege and non-privilege access to secure region
IFX_SE_PPC_SEC_MAX	Maximum value to fix enum size.

ifx_se_status_t ifx_se_ppc_config	(	const ifx_se_ppc_config_t *	ppc_config,
		void *	ctx
	)

Configures the PPC with the PC mask, security and access attributes.

This function allows to configure only WiFi SS SRAM PPC regions. Returns error if this function is called outside of WiFi SS PC.

Parameters

[in]	ppc_config	The pointer to the PPC configuration structure.
[in]	ctx	The pointer to the SE syscall context that contain a special syscall data (IPC release callback etc).
