[seL4 Announce] seL4 with proof on x64

Dear seL4 community, it’s my pleasure to announce that even more proofs have become available for seL4. In particular, the Intel x64 version of seL4 now has a functional correctness proof from abstract specification down to the C code. This brings the number of architecture configurations seL4 is verified for up to three (ARMv7, ARMv7 with hypervisor extensions, Intel x64) with a fourth one (RISC-V) in progress. The x64 functional correctness proof does not yet include the fast path, VT-x, or VT-d extensions, nor binary verification or the security proofs we have for ARM, but functional correctness is the core part for all of these other properties and is in itself a big step forward for reliability of the x64 code base. As usual, the proofs and code for seL4 are available on https://github.com/seL4/l4v and https://github.com/seL4/seL4. Enjoy! Gerwin for the Trustworthy Systems Team
