|
15 |
// Overview:
|
|
|
16 |
// Performs cache checking in order to ensure it is running correctly.
|
|
|
17 |
// Runs automatically or as manual test. (Type "t_cache help" for details.)
|
|
|
18 |
// API Information:
|
|
|
19 |
// class Cache
|
|
|
20 |
// class L2Cache
|
|
|
21 |
// Details:
|
|
|
22 |
// -Test1 - Displays cache properties.
|
|
|
23 |
// -Test2 - Gets thresholds.
|
|
|
24 |
// -Test3 - Sets thresholds.
|
|
|
25 |
// -Test4 - Compares different memory mappings of data.
|
|
|
26 |
// -Test5 - Compares different memory mappings of code.
|
|
|
27 |
// -Test6 - Tests Write Back mode.
|
|
|
28 |
// -Test7 - Tests cache maintenance functions
|
|
|
29 |
// It can also perform more specified tests if run manually:
|
|
|
30 |
// - t_cache info Test1 only
|
|
|
31 |
// - t_cache data <size_hex> Runs data chunk test (Test 4) with specified chunk size. For example,
|
|
|
32 |
// "t_cache data 10000" will run data chunk test against 64KB chunk.
|
|
|
33 |
// - t_cache code <size_hex> Runs code chunk test (Test 5) for specified chink size. For example,
|
|
|
34 |
// "t_cache code 10000" will run code chunk test against 64KB chunk.
|
|
|
35 |
// - t_cache data+<size_hex> Runs data chunk test for specified set of chunk sizes. For example,
|
|
|
36 |
// "t_cache data+1000" will perform data chunk test for sizes 4K, 8K,... up to 512K.
|
|
|
37 |
// - t_cache code+<size_hex> Runs code chunk test for specified set of sizes. For example,
|
|
|
38 |
// "t_cache code+1000" will perform code chunk test for sizes 4K, 8K,... up to 512K.
|
|
|
39 |
// - t_cache threshold Diplays thresholds for all caches on the platform.
|
|
|
40 |
// - t_cache threshold T P C H Sets new values for cache thresholds:
|
|
|
41 |
// - "T" specifies the type of cache to whose threshould are to be chenged:
|
|
|
42 |
// 1 for Instruction (or Unified) Cache.
|
|
|
43 |
// 2 for Data Cache (for ARMv7 and later, this is Point-of-Coherency threshold.
|
|
|
44 |
// 4 for XScale AltData Cache.
|
|
|
45 |
// 8 for Point-of-Unification Data Cache Threshold for ARMv7 and later platforms.
|
|
|
46 |
// 10 for L2 (L210 or XScale L2 cache)
|
|
|
47 |
// - "P" "C" & "H" are hex values for purge, clean & flush thresholds.
|
|
|
48 |
// For example: "t_cache 1 10000 10000 10000" sets 64KB for all thresholds in Instruction Cache.
|
|
|
49 |
// - t_cache usecase Runs particular use case tests.
|
|
|
50 |
// - t_cache help Displays the list of manual commands.
|
|
|
51 |
// Platforms/Drives/Compatibility:
