sl@0: // Description:
sl@0: // e32test\debug\t_cache.cpp
sl@0: // Overview:
sl@0: // Performs cache checking in order to ensure it is running correctly.
sl@0: // Runs automatically or as manual test. (Type "t_cache help" for details.)
sl@0: // API Information:
sl@0: // class Cache
sl@0: // class L2Cache
sl@0: // Details:
sl@0: // -Test1 - Displays cache properties.
sl@0: // -Test2 - Gets thresholds.
sl@0: // -Test3 - Sets thresholds.
sl@0: // -Test4 - Compares different memory mappings of data.
sl@0: // -Test5 - Compares different memory mappings of code.
sl@0: // -Test6 - Tests Write Back mode.
sl@0: // -Test7 - Tests cache maintenance functions
sl@0: // It can also perform more specified tests if run manually:
sl@0: // - t_cache info				Test1 only
sl@0: // - t_cache data <size_hex>	Runs data chunk test (Test 4) with specified chunk size. For example,
sl@0: // "t_cache data 10000" will run data chunk test against 64KB chunk.
sl@0: // - t_cache code <size_hex>	Runs code chunk test (Test 5) for specified chink size. For example,
sl@0: // "t_cache code 10000" will run code chunk test against 64KB chunk.
sl@0: // - t_cache data+<size_hex>	Runs data chunk test for specified set of chunk sizes. For example,
sl@0: // "t_cache data+1000" will perform data chunk test for sizes 4K, 8K,... up to 512K.
sl@0: // - t_cache code+<size_hex>	Runs code chunk test for specified set of sizes. For example,
sl@0: // "t_cache code+1000" will perform code chunk test for sizes 4K, 8K,... up to 512K.
sl@0: // - t_cache threshold			Diplays thresholds for all caches on the platform.
sl@0: // - t_cache threshold T P C H	Sets new values for cache thresholds:
sl@0: // - "T" specifies the type of cache to whose threshould are to be chenged:
sl@0: // 1  for Instruction (or Unified) Cache.
sl@0: // 2  for Data Cache (for ARMv7 and later, this is Point-of-Coherency threshold.
sl@0: // 4  for XScale AltData Cache.
sl@0: // 8  for Point-of-Unification Data Cache Threshold for ARMv7 and later platforms.
sl@0: // 10 for L2 (L210 or XScale L2 cache)
sl@0: // - "P" "C" & "H" are hex values for purge, clean & flush thresholds.
sl@0: // For example: "t_cache 1 10000 10000 10000" sets 64KB for all thresholds in Instruction Cache.
sl@0: // - t_cache usecase			Runs particular use case tests.
sl@0: // - t_cache help				Displays the list of manual commands.
sl@0: // Platforms/Drives/Compatibility:
sl@0: // Hardware - ARM only (Manual). Not supported on emulator.
sl@0: // Assumptions/Requirement/Pre-requisites:
sl@0: // Failures and causes:
sl@0: // Base Port information:
sl@0: // d_cache.mmp to be built from the baseport.
