[lwip-devel] [patch #7885] modification of api modules to support FreeRTOS-MPU (NO_SYS = 0)

[Simon Goldschmidt]

Follow-up Comment #1, patch #7885 (project lwip):

Thanks for the patch. It does make sense if you want MPU support enabled.

However, I don't think this will be true for all platforms and your patch
*does* decrease performance on these platforms (while it does not gain
anything there). In fact, the memp_malloc/memp_free-thing was how it was until
1.2.0 or so. We changed it to stack-allocation for performance reasons, then.

Being like that, I'm rather thinking about a config option for MPU support. I
guess there might be other changes which would be nice for MPU systems but not
necessary for MPU-less systems.
