The purpose of this is to enable use of the Signal Processing + Engine found in the NXP/Freescale e500v2 SoC. The SPE uses + opcodes overlapping with Altivec, so is mutually exclusive. + Additionally, the e500v2 does not have a traditional FPU, and + instead uses the SPE for all floating point operations (or + emulation as is currently done). Combined with the fact that + the SPE ABI is incompatible with traditional ABI, a new + MACHINE_ARCH is created to address this.

+ +

A project branch has been created with the work. A + powerpcspe kernel boots on the RouterBoard RB800, and base + utilities run properly.

+ + + + +

Potentially optimizing setjmp/longjmp to not use SPE unless + it's already been enabled. This would save the kernel + switch for processes that don't otherwise use the SPE. This + is a low priority task which may not be completed.
