Reading the status in the VFP fault handler does not work since at that point the VFP already got disabled. ok kettenis@ Make FPU registers available in core dumps and through ptrace(2). 2018-03-16T21:46:04Z kettenis kettenis@openbsd.org 2018-03-16T21:46:04Z urn:sha1:8ea539eebb4310a7e367926117e67f7f26934256 ok visa@, patrick@ Add kernel support for the VFP FPU/SIMD unit. Based on a diff by drahn@. 2018-01-26T16:22:19Z kettenis kettenis@openbsd.org 2018-01-26T16:22:19Z urn:sha1:c7b5578a715ca65ee46f2c1c48fca8629620c8ce This allows us to use floating-pointer and vector instructions in userland code. The current implementation assumes all 32 VFP registers are present. This should be the case on all armv7 hardware currently supported by OpenBSD. ok patrick@
