PVR_K: RA_Alloc FAILED

Hans Mueller1

Other Parts Discussed in Thread: 4460

Hi!

I currently running in problems when loading the Android 4.4 easter egg. It loads and crashes.
I own a custom 4460 board with 1GByte of RAM and 540SGX graphics.

A look into the logcat gives me the output below. Now I want to understand what this means.
Is no more the physically memory available at all or "only" some special memory (maybe I can tune some bit if I know what's the cause).

I putted some debug statements at the kernel driver and it confuses me some more ;) It shows me the following:

Inside the "MMU_Create", the function "RA_Create" is called with some "null" parameters, which causes the RA_Create function to use the default callback for memory allocation "_RequestAllocFail". This function is used in RA_Alloc: bResult =  pArena->pImportAlloc() which is intended to fail and causes the OutOfMemory exception.

Why the RA_Alloc uses this path at this point. Why it doesn't behave this way all the previous (successful) memory allocations?

    Hi Hans,

    what version of the DDK are you using?

    The problem perhaps  is do to asynchronous allocation of RA_Alloc when the memory is still in use by something, which causes the fault. 

    Regards,

    Thanks for your reply!

    I tried the DDK 1.9@2291151 and also the revision 1.9@2166536 with the same results.

    I enabled some debugging output and created a logfile which is attached to this post, which contains some snippets of the following sections:

    • Kernel boot log
    • PVR Drivers starts
    • SGX application starts
    • SGX RA_Alloc failed

    1452.Detailled_log.zip

    Note that I added a dump_stack() on each RA_Alloc to get some more logging information and to see what's going on. I can add some more, please let me know which debugging statements I should enable.

    Looking forward to squash this issue!

    Regards,
    H.Mueller
