Methods
impl SCB[src]
pub fn enable_icache(&self)[src][−]
Enables I-Cache if currently disabled
pub fn disable_icache(&self)[src][−]
Disables I-Cache if currently enabled
pub fn icache_enabled(&self) -> bool[src][−]
Returns whether the I-Cache is currently enabled
pub fn invalidate_icache(&self)[src][−]
Invalidates I-Cache
pub fn enable_dcache(&self, cpuid: &CPUID)[src][−]
Enables D-cache if currently disabled
pub fn disable_dcache(&self, cpuid: &CPUID)[src][−]
Disables D-cache if currently enabled
pub fn dcache_enabled(&self) -> bool[src][−]
Returns whether the D-Cache is currently enabled
pub fn clean_dcache(&self, cpuid: &CPUID)[src][−]
Cleans D-cache
pub fn clean_invalidate_dcache(&self, cpuid: &CPUID)[src][−]
Cleans and invalidates D-cache
pub fn invalidate_dcache_by_address(&self, addr: usize, size: usize)[src][−]
Invalidates D-cache by address
addr: the address to invalidate
size: size of the memory block, in number of bytes
Invalidates cache starting from the lowest 32-byte aligned address represented by addr,
in blocks of 32 bytes until at least size bytes have been invalidated.
pub fn clean_dcache_by_address(&self, addr: usize, size: usize)[src][−]
Cleans D-cache by address
addr: the address to clean
size: size of the memory block, in number of bytes
Cleans cache starting from the lowest 32-byte aligned address represented by addr,
in blocks of 32 bytes until at least size bytes have been cleaned.
pub fn clean_invalidate_dcache_by_address(&self, addr: usize, size: usize)[src][−]
Cleans and invalidates D-cache by address
addr: the address to clean and invalidate
size: size of the memory block, in number of bytes
Cleans and invalidates cache starting from the lowest 32-byte aligned address represented
by addr, in blocks of 32 bytes until at least size bytes have been cleaned and
invalidated.
