[LTP] hardware requirements

Hi,

Is there an agreed upon set of hardware requirements (memory, disk space,
etc.) for running, if not all tests, at least the default testcases
executed by runltp?

Also, if not very knowledgeable of hardware, is there an easy way to tell
if a particular test will run on a target platform or not?  For example, I
suspect the DMA_THREAD_DIOTEST7 tests are not expected to run on all
architectures.  Is there a way to find out what platforms it does support?

Thanks,
- Mark Ver

many of test cases dont care at all about resources.  might be useful to have 
an embedded doc format so tests that do care about resources can declare them 
and then a script can run periodically to collect all of them in a summary 
format.

i'm pretty sure that in the vast majority of cases, the memory size is the 
only thing that a test may play with.

Yeah, I guess I was thinking of tests like hackbench which don't seem to
run well on systems with little memory.  And some of the growfiles tests
seem to be a little sensitive about the amount of free /tmp space.

Several tests are also sensitive to the size of the filesystem. While most systems shouldn't have a problem, we have hit these limitations when testing flash filesytems, etc.
