From d82e521995832580e990c0c173651aafd43d299c Mon Sep 17 00:00:00 2001 From: Alexander Kanavin Date: Sat, 24 Dec 2022 17:59:43 +0100 Subject: qemu: update 7.1.0 -> 7.2.0 qemu no longer carries libslirp in-tree, so enabling slirp requires providing external libslirp. Another noteworthy change is: x86: TCG support for AVX, AVX2, F16C, FMA3 and VAES instructions ... which means both meta-intel and qemu x86 targets can now fully utilize Haswell-and-later instruction set with benefits for performance in emulation and on silicon.
