arm64 port (aarch64 architecture), kernel virtual machine for arm64 (kvm/arm64), the rest · Maintainers:
Catalin Marinas, Will Deacon, Marc Zyngier, Oliver Upton, Linus Torvalds
With VHE and nVHE executable code completely separated, remove build config that disabled GCOV/KASAN/UBSAN/KCOV instrumentation for VHE as these now execute under the same memory mappings as the rest of the kernel. No violations are currently being reported by either KASAN or UBSAN. Signed-off-by: David Brazdil <redacted> --- arch/arm64/kvm/hyp/Makefile | 8 -------- 1 file changed, 8 deletions(-)
