Merge of Wu's GSOC 09 branch (src.20090525.r4372.wu)
Main changes: - COW optimization for safecopy. - safemap, a grant-based interface for sharing memory regions between processes. - Integration with safemap and complete rework of DS, supporting new data types natively (labels, memory ranges, memory mapped ranges). - For further information: http://wiki.minix3.org/en/SummerOfCode2009/MemoryGrants Additional changes not included in the original Wu's branch: - Fixed unhandled case in VM when using COW optimization for safecopy in case of a block that has already been shared as SMAP. - Better interface and naming scheme for sys_saferevmap and ds_retrieve_map calls. - Better input checking in syslib: check for page alignment when creating memory mapping grants. - DS notifies subscribers when an entry is deleted. - Documented the behavior of indirect grants in case of memory mapping. - Test suite in /usr/src/test/safeperf|safecopy|safemap|ds/* reworked and extended. - Minor fixes and general cleanup. - TO-DO: Grant ids should be generated and managed the way endpoints are to make sure grant slots are never misreused.

Test Program for DataServer
|
||||||
|
|
||||||
|
How to run
|
||||||
|
==========
|
||||||
|
|
||||||
|
1. Type `make run` to prepare and run test.
|
||||||
|
2. When done testing, type `make clean` to clean up.
|
||||||
|
|
||||||
|
How the test works
|
||||||
|
==================
|
||||||
|
|
||||||
|
`dstest` tests the new DS API (excluding ds_subscribe() and ds_check()).
|
||||||
|
test_u32, test_str, test_mem, test_label, and test_map test U32, STR, MEM, LABEL
|
||||||
|
and MAP type respectively.
|
||||||
|
|
||||||
|
Invalid invokation is tested as well. Erroneous conditions are tested only once.
|
||||||
|
For example, publishing an entry with same label name, but without
|
||||||
|
DSF_OVERWRITE set, is tested in test_u32 and nowhere else again.
|
||||||
|
Type-specific features are always tested.
|
||||||
|
|
||||||
|
`subs` tests ds_subscribe() and ds_check(). The server subscribes
|
||||||
|
to a U32 type. When `dstest` runs, `subs` catches all the updates.

Test Program for Safecopy with or without COW
|
||||||
|
|
||||||
|
How to run
|
||||||
|
==========
|
||||||
|
|
||||||
|
Test safecopy with COW:
|
||||||
|
1. Set USE_COW_SAFECOPY to 1 in /usr/src/kernel/system/do_safecopy.c
|
||||||
|
2. Type `make run` to prepare and run test.
|
||||||
|
3. When done testing, type `make clean` to clean up.
|
||||||
|
|
||||||
|
Test safecopy without COW:
|
||||||
|
1. Set USE_COW_SAFECOPY to 0 in /usr/src/kernel/system/do_safecopy.c
|
||||||
|
2. Type `make run` to prepare and run test.
|
||||||
|
3. When done testing, type `make clean` to clean up.
|
||||||
|
|
||||||
|
If you want to modify the test buffer size:
|
||||||
|
1. Modify TEST_PAGE_NUM in inc.h
|
||||||
|
2. Modify TEST_PAGE_SHIFT in inc.h

Performance Test Program for Safecopy and Safemap
|
||||||
|
|
||||||
|
How to run
|
||||||
|
==========
|
||||||
|
|
||||||
|
1. Set USE_COW_SAFECOPY to 1 or 0 in kernel/system/do_safecopy.c
|
||||||
|
to run safecopy tests with or without COW optimization.
|
||||||
|
2. Type `make run` to prepare and run tests. Configuration parameters
|
||||||
|
for performance tests are in ./run.
|
||||||
|
3. When done testing, type `make clean` to clean up.
