This series makes the necessary changes to allow the use of --disable-tcg for arm.
For the v2 I have taken a more strict approach to avoid introducing changes in behavior, specially regarding the cpregs hash table. changes: patch 5: Move all cpregs related code from helper.c into cpregs.c; patches 6 & 7: These are ARMCPRegInfo and accessors that are currently in helper files. I moved them into cpregs.c, otherwise we can't move the helpers into tcg/ patch 11: Richard suggested we handle the tcg_enable check in a header, but I noticed that are many more instances of arm_rebuild_hflags being called from code that is tcg-only, so I'm not sure if we want to have the added overhead in all calls. I have extracted all of the new tcg_enable() calls so we can judge if it's worth it. dropped the previous patch 11: [RFC PATCH 11/27] target/arm: only perform TCG cpu and machine inits if TCG enabled This patch had a mistake when we moved register_cp_regs_for_features() under tcg_enabled(). That caused the cp_regs hash table to be empty and no registers being written in write_cpustate_to_list(). v1: https://lore.kernel.org/r/20230104215835.24692-1-faro...@suse.de I have included the other two already reviewed series to facilitate the merge. Patch 12 is the first from this series proper. I could use some help with the last two patches which deal with the fact that ptw.c needs CPUTLBEntryFull and probe_access_full which are _currently_ only compiled with CONFIG_TCG=y. The 3 cpregs patches were split from the larger commit[1] from the original series. We're still left with one huge patch, but it is only code movement, it can be checked with: diff -u <(sed -n 's/^-//p' patch) <(sed -n 's/^\+//p' patch) 1- [RFC v14 14/80] target/arm: split cpregs from tcg/helper.c https://lore.kernel.org/r/20210416162824.25131-15-cfont...@suse.de Claudio Fontana (8): target/arm: rename handle_semihosting to tcg_handle_semihosting target/arm: wrap psci call with tcg_enabled target/arm: wrap call to aarch64_sve_change_el in tcg_enabled() target/arm: move helpers to tcg/ target/arm: Move psci.c into the tcg directory tests: do not run test-hmp on all machines for ARM KVM-only tests: do not run qom-test on all machines for ARM KVM-only tests: device-introspect-test: cope with ARM TCG-only devices Fabiano Rosas (11): target/arm: Move PC alignment check target/arm: Move cpregs code into cpregs.c target/arm: Move define_debug_regs() to cpregs.c target/arm: Move helper_set_pstate_* into cpregs.c target/arm: move translate modules to tcg/ target/arm: Wrap arm_rebuild_hflags calls with tcg_enabled target/arm: Move hflags code into the tcg directory tests/tcg: Do not build/run TCG tests if TCG is disabled target/arm: Move regime_using_lpae_format into internal.h cpu-defs.h: Expose CPUTLBEntryFull to non-TCG code target/arm: don't access TCG code when debugging with KVM MAINTAINERS | 1 + configure | 4 + hw/arm/boot.c | 6 +- hw/intc/armv7m_nvic.c | 20 +- include/exec/cpu-defs.h | 6 + target/arm/arm-powerctl.c | 7 +- target/arm/cpregs.c | 9505 +++++++++++++++++++++++ target/arm/cpu.c | 10 +- target/arm/helper.c | 9459 +--------------------- target/arm/internals.h | 32 +- target/arm/machine.c | 31 +- target/arm/meson.build | 48 +- target/arm/ptw.c | 4 + target/arm/tcg-stubs.c | 33 + target/arm/{ => tcg}/a32-uncond.decode | 0 target/arm/{ => tcg}/a32.decode | 0 target/arm/{ => tcg}/crypto_helper.c | 0 target/arm/{ => tcg}/debug_helper.c | 367 -
