</div>Thanks!<br>
My main concern is if a BSP doesn't have libmm built, will building all the tests lead to a compiler / linker error?<br>
If not, we needn't worry about building conditionally...</blockquote><div>There are stubs for libmm functions at a high-level APIs at no_memorymanagement.c file. So, every BSP/CPU that does not implement libmm functions can be built without error with including that file. </div>

I'm mostly worried about getting these tests committed incrementally if feasible (i.e. they don't break the build)...<br>
<br>
Hopefully we can get your work committed over the summer and reduce the number of patches at the end of the summer :)<br>

Hi,<br>
<br>
Thanks for providing the link directly to the testcases!<br>
Could you copy the information about each test into:<br>
<br>
mmtest1/mmtest1.doc<br>
Simple tests that tries to install memory management entries<br>
<br>
mmtest2/mmtest2.doc<br>
+ Install entries with specific memory attributes (e.g read only region) :<br>
+ Check for memory protection violations (writing to read only blocks)<br>
+ Reading from read only blocks.<br>
+ Write/Read to/from unmapped region (error!).<br>
+ Write to a valid entry that was installed and then uninstalled (error!).<br>
<br>
mmtest3/mmtest3.doc<br>
+ Tests for libmm behavior on SMP environments.<br>
+ Create tasks for each core and start it.<br>
+ Check for memory consistency and page tables and memory attributes validity.<br>
<br>
That way we can quickly identify what each test does in 5 years... Good job with the documentation :)<br>
<br>
Cindy<br>

Subject: [GSoC] libmm project status<br>
<br>
Hi all,<br>
<br>
I have posted a new thread to my blog that contains a brief introduction to libmm and latest updates, here is the thread [1] Please take a look.<br>
<br>
TODO: port libmm for Raspberry PI board on real hardware.<br>
<br>
Questions :<br>
<br>
I have created a new test case at libtests called mmtest3 [2] which simulate SMP use case on QEMU/Realview. It simply tries to invoke the same task (which calls libmm function) for each core. There is a fatal error at startup that branches to data exception handler but I am not sure why. Please take a look and tell me if I am doing something wrong with that test case.<br>
<br>
Other test cases (mmtest1, mmtest2) run successfully on the same platform.<br>
