14 // e32test\debug\t_cache.cpp |
|
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: |
|
52 // Hardware - ARM only (Manual). Not supported on emulator. |
|
53 // Assumptions/Requirement/Pre-requisites: |
|
54 // Failures and causes: |
|
55 // Base Port information: |
|
56 // d_cache.mmp to be built from the baseport. |
