TL;DR: This series restrict TCG-specific objects by moving them to the tcg/ subdir. Code is moved around to satisfy 3 cases: { generic sysemu / tcg sysemu / tcg user}. Hi, This series move the MIPS TCG files under target/mips/tcg/. tcg/ is split into {sysemu and user}, and code common to both user/sysemu is left under tcg/ root. Non-user code is moved to sysemu/ (common to TCG and KVM). - Patches 1 & 6 are Meson generic - Patches 2 to 5 move generic symbols around to satisfly KVM linking - Patch 8 introduces tcg-internal.h where we'll move TCG specific prototypes from the current big internal.h - Patches 9-24 move code by topic (first user, then sysemu, then tcg) - Patch 25 restrict TCG specific machines to TCG (to actually only build malta/loongson3-virt machines when restricted to KVM) - Patch 26 finally add a CI job with "KVM-only" config: https://gitlab.com/philmd/qemu/-/jobs/1189874868 (12min 5sec) Diffstat is not that bad, and many #ifdef'ry removed. Please review, Phil.

Non-user code is moved to sysemu/ (common to TCG and KVM). - Patches 1 & 10 are Meson generic - Patches 2 to 9 move generic symbols around to satisfly KVM linking - Patch 11 introduces tcg-internal.h where we'll move TCG specific prototypes from the current big internal.h - Patches 12-27 move code by topic (first user, then sysemu, then tcg) - Patch 28 restrict TCG specific machines to TCG (to actually only build malta/loongson3-virt machines when restricted to KVM) - Patch 29 finally add a CI job with "KVM-only" config: https://gitlab.com/philmd/qemu/-/jobs/1189874868 (12min 5sec) Diffstat is not that bad, and many #ifdef'ry removed.
