i am facing cmem issues:

The insmod i am using to allocate cmem memory is as follows:
insmod cmemk.ko phys_start=0x85000000 phys_end=0x88000000
pools=6x4096,2x8192,1x11908,2x13184,1x2697152,6x4096,1x30720,3x81920,1x3185664,64x56,1x320,1x640,1x81920,1x6650880,2x608,1x296,1x28,2x24,23x1548288,1x154288 phys_start_1=0x00001000 phys_end_1=0x00008000 pools_1=1x28672c allowOverlap=1 useHeapIfPoolUnavailable=1

also i have tried following combinations but none is working:

insmod cmemk.ko phys_start=0x85000000 phys_end=0x88000000 pools=6x4096,2x8192,1x11908,2x13184,1x2697152,6x4096,1x30720,3x81920,1x3185664,64x56,1x320,1x640,1x81920,1x6650880,2x608,1x296,1x28,2x24,23x1548288,1x154288 phys_start_1=0x00001000 phys_end_1=0x00500000 pools_1=1x400000c allowOverlap=1 useHeapIfPoolUnavailable=1

insmod cmemk.ko phys_start=0x84c00000 phys_end=0x88000000 pools=8x4667200 useHeapIfPoolUnavailable=1



All are leading to one or the other cmem error.

My doubts:
1.I am still not able to calculate how i can give sufficient memory to
cmem so that i can be able to run ipnc application.Is there any method
to do this:
2.Also if you could tell me your insmod command so that i can be able to
run ipnc application fine.
3.Does enabling the debug info leads to higher memory requirements from
cmem.

Thanks and Regards,
Mayank

    The way to track CMEM memory usage is to turn on debug output.  Here's a link to how to turn on user-level debug output: http://processors.wiki.ti.com/index.php/CMEM_Overview#Debugging_Techniques.  You can turn on kernel module output by doing "make debug" in the kernel module directory <linuxutils>/ti/sdo/linuxutils/cmem/src/module.

    With the CMEM debug output you can "track" all allocations and frees, keeping a running total for what you need at any given time.  It's crude, but effective.

    insmod cmemk.ko phys_start=0x84c00000 phys_end=0x88000000 pools=8x4667200 useHeapIfPoolUnavailable=1

    The above configuration is not going to do very well, since pool-based allocations will use any "big enough" pool, so your 8 buffers of size 4667200 might get consumed by very small buffer allocations (and wasting precious CMEM memory), leaving only the heap to satisfy the big allocations.

    A common method during development is to have CMEM memory be all heap, which is accomplished by not specifying "pools=", along with having "useHeapIfPoolUnavailable=1":
        % insmod cmemk.ko phys_start=0x84c00000 phys_end=0x88000000 useHeapIfPoolUnavailable=1
    In this way, all pool-based requests will fallback to the heap, and the heap allocations will be sized efficiently (with allocations rounded up to the nearest PAGE_SIZE of 4 KB).  When doing so and having debug info enabled, you can track all allocations for the life of the app.  Once you know all allocation requests you can reduce CMEM memory to what is needed and construct pools according to the app needs (and you probably want pools instead of heap to avoid heap fragmentation issues).

    I'm wondering what memory you're trying to use with your "_1" specifications.  The size of the "pools_1" needs to be <= (phys_end_1 - phys_start_1).  Both examples I quote above have a pools_1 size > the amount of memory specified with phys_start_1/phys_end_1.

    No, not as far as the phys_start/phys_end block (but more mem for application since it has printfs).
