Hi Rajendra,

Glad to hear! You are most welcome. Thank you for the note.
Do let us know how the experience using the tool on the p2020 goes.

Regards,

Hi Anmol,

Thanks for all the help. I tried valgrind sources in Freescale SDK 1.6 and I am able to run valgrind on P2020 with powerpcspe ABI.

Regards,
Rajendra

Hi Rajendra,

The port also comes with a regression test that has a unit-test for each SPE insn, please see: https://bugs.kde.org/show_bug.cgi?id=321396#c7

Thanks,
Anmol.

Hi Rajendra,


 Actually, see:  meta-fsl-networking/recipes-devtools/valgrind/files/*.patch
and the SRC_URI variable in meta-fsl-networking/recipes-devtools/valgrind/valgrind_fsl.bb that lists the patches that get applied in the SDK.

Regards,
Anmol.

Hi Rajendra,

We do not have them in 3.9.0 but following http://valgrind.org/downloads/repository.html if you get a current repository then
doing a: 'svn diff -c 13504 configure.ac' likely gets you the patch that you are looking for.

Regards,
Anmol.

HI Anmol,

Thanks for all the help.

I downloaded the 1.6 SDK and was able to find the valgrind-3.8.1. However the buildroot based cross-toolchain uses glibc-2.18 which is not supported in valgrind-3.8.1. It requires later versions of 3.9.0 onwards. Can you please let me know if the SPE patches are available for a Valgrind-3.9.0 based sources.

Regards,
Rajendra

Hi,

I noticed that Valgrind-3.9.0 does not support the powerpc SPE based toolchains for e500v2 based platforms.  buildroot currently does not allow classic PowerPC ABI to be selectable for e500v2/e500v1 class of machines.

I do not want to switch to classic ABI as I want to build toolchains out of buildroot without any customizations. Is there any patch available for Valgrind to support SPE instructions.

Thanks,
Rajendra Dendukuri

Hi Rajendra,

We have made available, a Valgrind-3.8.1 based port to e500v2 SPE; please see: https://bugs.kde.org/show_bug.cgi?id=321396#c6
The instructions are for an earlier version of the SDK, but everything should essentially still be the same, please use:
