// 1. Load executables with the RProcess API and run them. Each executable has a
|
|
|
22 |
// different set of attributes:
|
|
|
23 |
// " Paging attribute: paged, unpaged or no paging attribute in MMP and/or
|
|
|
24 |
// OBY files
|
|
|
25 |
// " Compression mode: specified or not
|
|
|
26 |
// " Executable built in ROM as 'data' or 'file'
|
|
|
27 |
// " Solid binaries or aliases
|
|
|
28 |
// Retrieve and analyse the demand paging activity trace caused by the preceding
|
|
|
29 |
// action, in order to determine whether this binary is paged on demand or not.
|
|
|
30 |
// 2. Repeat the preceding action by loading DLLs with the RLibrary API and
|
|
|
31 |
// making calls to them.
|
|
|
32 |
// @SYMTestExpectedResults
|
|
|
33 |
// 1. Process complete without error. If, according to the trace data gathered,
|
|
|
34 |
// the main thread newly created process causes the executable to be paged in,
|
|
|
35 |
// then it is a proof that the executable is paged. Depending on the Paging
|
|
|
36 |
// Override setting and the Loader Paging Policy specified at the time the ROM was
|
|
|
37 |
// built, the Loader makes a decision as to whether page the binary or not,
|
|
|
38 |
// according to the rules listed in the Design Sketch. This is how we determine
|
|
|
39 |
// this, in this order:
|
|
|
40 |
// a. If ROM paging is disabled: not paged
|
|
|
41 |
// b. If executable was built in ROM as 'data': not paged
|
|
|
42 |
// c. If the a file compression scheme was specified at ROM build time: not paged
|
|
|
43 |
// d. If the Loader Paging policy is 'NOT PAGED': not paged
|
|
|
44 |
// e. If the Loader Paging policy is 'ALWAYS PAGE': paged
|
|
|
45 |
// f. If the Paging Override is 'NOT PAGED': not paged
|
|
|
46 |
// g. If the Paging Override is 'ALWAYS PAGE': paged
|
|
|
47 |
// h. If the OBY paging keyword for this executable is 'PAGED': paged
|
|
|
48 |
// i. If the OBY paging keyword for this executable is 'NOT PAGED': unpaged
|
|
|
49 |
// j. If the MMP paging keyword for this executable is 'PAGED': paged
|
|
|
50 |
// k. If the MMP paging keyword for this executable is 'NOT PAGED': not paged
|
|
|
51 |
// l. If the Paging Override is 'DEFAULT UNPAGED': not paged
|
|
|
52 |
// m. If the Paging Override is 'DEFAULT PAGED': paged
|
|
|
53 |
// n. If the Paging Policy is 'DEFAULT UNPAGED': not paged
|
|
|
54 |
// o. The executable must be paged
|
|
|
55 |
// 2. DLL is loaded. Functions are called and complete without errors. The rules
|
|
|
56 |
// to determine whether the binary should be paged or not are the same as in the
|
|
|
57 |
// preceding action.
