| errnum_t R_OSPL_AXI_Get2ndCacheAttribute | ( | uintptr_t const | PhysicalAddress, |
| r_ospl_axi_cache_attribute_t *const | out_CacheAttribute | ||
| ) |
Get 2nd cache attribute of AXI bus for peripheral (not CPU) from physical address.
- Parameters:
-
PhysicalAddress The physical address in the memory area out_CacheAttribute Output: Cache_attribute, AWCACHE[3:0], ARCACHE[3:0]
- Returns:
- Error code. If there is no error, the return value is 0.
Definition at line 359 of file r_ospl_memory.c.
| errnum_t R_OSPL_AXI_GetProtection | ( | uintptr_t const | physical_address, |
| r_ospl_axi_protection_t *const | out_protection | ||
| ) |
Gets protection attribute of AXI bus from the address.
- Parameters:
-
PhysicalAddress The physical address in the memory area out_CacheAttribute Output: The protection attribute of AXI bus AWPROT[2:0], ARPROT[2:0]
- Returns:
- Error code. If there is no error, the return value is 0.
Definition at line 416 of file r_ospl_memory.c.
| errnum_t R_OSPL_MEMORY_GetLevelOfFlush | ( | const void * | Address, |
| int_fast32_t * | out_Level | ||
| ) |
Gets the level of cache for flushing the memory indicated by the address.
- Parameters:
-
Address The address in flushing memory out_Level Output: 0=Not need to flush, 1=L1 cache only, 2=both of L1 and L2 cache
- Returns:
- Error code. If there is no error, the return value is 0.
Definition at line 290 of file r_ospl_memory.c.
| errnum_t R_OSPL_ToCachedAddress | ( | const volatile void *const | Address, |
| void *const | out_CachedAddress | ||
| ) |
Changes to the address in the L1 cache area.
- Parameters:
-
Address Virtual address out_CachedAddress Output: Virtual address for cached area
- Returns:
- Error code. If there is no error, the return value is 0.
- Description
- This function must be modified by MMU setting. If "E_ACCESS_DENIED" error was raised, you may know the variable by looking at value of "Address" argument and map file.
Definition at line 157 of file r_ospl_memory.c.
| errnum_t R_OSPL_ToPhysicalAddress | ( | const volatile void *const | Address, |
| uintptr_t *const | out_PhysicalAddress | ||
| ) |
Changes to physical address.
- Parameters:
-
Address Virtual address out_PhysicalAddress Output: Physical address
- Returns:
- Error code. If there is no error, the return value is 0.
- Description
- This function must be modified by MMU setting.
Definition at line 134 of file r_ospl_memory.c.
| errnum_t R_OSPL_ToUncachedAddress | ( | const volatile void *const | Address, |
| void *const | out_UncachedAddress | ||
| ) |
Changes to the address in the L1 uncached area.
- Parameters:
-
Address Virtual address out_UncachedAddress Output: Virtual address for uncached area
- Returns:
- Error code. If there is no error, the return value is 0.
- Description
- This function must be modified by MMU setting. If "E_ACCESS_DENIED" error was raised, you may know the variable by looking at value of "Address" argument and map file.
