    1.16 +// Description:
    1.17 +// e32test\debug\t_cache.cpp
    1.18 +// Overview:
    1.19 +// Performs cache checking in order to ensure it is running correctly.
    1.20 +// Runs automatically or as manual test. (Type "t_cache help" for details.)
    1.21 +// API Information:
    1.22 +// class Cache
    1.23 +// class L2Cache
    1.24 +// Details:
    1.25 +// -Test1 - Displays cache properties.
    1.26 +// -Test2 - Gets thresholds.
    1.27 +// -Test3 - Sets thresholds.
    1.28 +// -Test4 - Compares different memory mappings of data.
    1.29 +// -Test5 - Compares different memory mappings of code.
    1.30 +// -Test6 - Tests Write Back mode.
    1.31 +// -Test7 - Tests cache maintenance functions
    1.32 +// It can also perform more specified tests if run manually:
    1.33 +// - t_cache info				Test1 only
    1.34 +// - t_cache data <size_hex>	Runs data chunk test (Test 4) with specified chunk size. For example,
    1.35 +// "t_cache data 10000" will run data chunk test against 64KB chunk.
    1.36 +// - t_cache code <size_hex>	Runs code chunk test (Test 5) for specified chink size. For example,
    1.37 +// "t_cache code 10000" will run code chunk test against 64KB chunk.
    1.38 +// - t_cache data+<size_hex>	Runs data chunk test for specified set of chunk sizes. For example,
    1.39 +// "t_cache data+1000" will perform data chunk test for sizes 4K, 8K,... up to 512K.
    1.40 +// - t_cache code+<size_hex>	Runs code chunk test for specified set of sizes. For example,
    1.41 +// "t_cache code+1000" will perform code chunk test for sizes 4K, 8K,... up to 512K.
    1.42 +// - t_cache threshold			Diplays thresholds for all caches on the platform.
    1.43 +// - t_cache threshold T P C H	Sets new values for cache thresholds:
    1.44 +// - "T" specifies the type of cache to whose threshould are to be chenged:
    1.45 +// 1  for Instruction (or Unified) Cache.
    1.46 +// 2  for Data Cache (for ARMv7 and later, this is Point-of-Coherency threshold.
    1.47 +// 4  for XScale AltData Cache.
    1.48 +// 8  for Point-of-Unification Data Cache Threshold for ARMv7 and later platforms.
    1.49 +// 10 for L2 (L210 or XScale L2 cache)
    1.50 +// - "P" "C" & "H" are hex values for purge, clean & flush thresholds.
    1.51 +// For example: "t_cache 1 10000 10000 10000" sets 64KB for all thresholds in Instruction Cache.
    1.52 +// - t_cache usecase			Runs particular use case tests.
    1.53 +// - t_cache help				Displays the list of manual commands.
    1.54 +// Platforms/Drives/Compatibility:
    1.55 +// Hardware - ARM only (Manual). Not supported on emulator.
