linux-toradex.git/arch/powerpc/kernel/ppc32.h, branch v3.4.2 Linux kernel for Apalis and Colibri modules powerpc: Add VSX context save/restore, ptrace and signal support 2008-07-01T01:28:50+00:00 Michael Neuling mikey@neuling.org 2008-06-25T04:07:18+00:00 ce48b2100785e5ca629fb3aa8e3b50aca808f692 This patch extends the floating point save and restore code to use the VSX load/stores when VSX is available. This will make FP context save/restore marginally slower on FP only code, when VSX is available, as it has to load/store 128bits rather than just 64bits. Mixing FP, VMX and VSX code will get constant architected state. The signals interface is extended to enable access to VSR 0-31 doubleword 1 after discussions with tool chain maintainers. Backward compatibility is maintained. The ptrace interface is also extended to allow access to VSR 0-31 full registers.

The signals interface is extended to enable access to VSR 0-31
doubleword 1 after discussions with tool chain maintainers.  Backward
compatibility is maintained.

The ptrace interface is also extended to allow access to VSR 0-31 full
registers.
