[GSoC] libmm project status

[Rempel, Cynthia]

Hi,

Thanks for providing the link directly to the testcases!
Could you copy the information about each test into:

mmtest1/mmtest1.doc
Simple tests that tries to install memory management entries

mmtest2/mmtest2.doc
+ Install entries with specific memory attributes (e.g read only region) : 
+ Check for memory protection violations (writing to read only blocks) 
+ Reading from read only blocks. 
+ Write/Read to/from unmapped region (error!). 
+ Write to a valid entry that was installed and then uninstalled (error!). 

mmtest3/mmtest3.doc
+ Tests for libmm behavior on SMP environments.
+ Create tasks for each core and start it. 
+ Check for memory consistency and page tables and memory attributes validity. 

That way we can quickly identify what each test does in 5 years... Good job with the documentation :)

Cindy

Hi all,

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.

TODO: port libmm for Raspberry PI board on real hardware.

Questions :

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.

Other test cases (mmtest1, mmtest2) run successfully on the same platform.
