Hi, This series is inspired on Claudio TCG work.
Instead of separate TCG from other accelerators, here we separate sysemu operations (system VS user). Patches 1-6 are generic cleanups. Patches 7-15 move from CPUClass to SysemuCPUOps Patch 16 restricts SysemuCPUOps to sysemu Patches 17-25 remove watchpoint code from user emulation Patches 26-27 remove USER_ONLY #ifdef'ry from "cpu.h" Since v2: - fixed lm32/unicore32 - remove USER_ONLY ifdef'ry from "cpu.h" (Claudio) Since v1: - Name 'sysemu' (Claudio) - change each field progressively (Richard) $ git backport-diff -u v2 Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respective= ly 001/27:[----] [--] 'target: Set CPUClass::vmsd instead of DeviceClass::vmsd' 002/27:[----] [--] 'cpu: Un-inline cpu_get_phys_page_debug and cpu_asidx_from= _attrs' 003/27:[----] [--] 'cpu: Introduce cpu_virtio_is_big_endian()' 004/27:[----] [--] 'cpu: Directly use cpu_write_elf*() fallback handlers in p= lace' 005/27:[----] [--] 'cpu: Directly use get_paging_enabled() fallback handlers = in place' 006/27:[----] [--] 'cpu: Directly use get_memory_mapping() fallback handlers = in place' 007/27:[----] [--] 'cpu: Introduce SysemuCPUOps structure' 008/27:[----] [--] 'cpu: Move CPUClass::vmsd to SysemuCPUOps' 009/27:[----] [--] 'cpu: Move CPUClass::virtio_is_big_endian to SysemuCPUOps' 010/27:[----] [--] 'cpu: Move CPUClass::get_crash_info to SysemuCPUOps' 011/27:[----] [--] 'cpu: Move CPUClass::write_elf* to SysemuCPUOps' 012/27:[----] [--] 'cpu: Move CPUClass::asidx_from_attrs to SysemuCPUOps' 013/27:[----] [--] 'cpu: Move CPUClass::get_phys_page_debug to SysemuCPUOps' 014/27:[----] [--] 'cpu: Move CPUClass::get_memory_mapping to SysemuCPUOps' 015/27:[----] [--] 'cpu: Move CPUClass::get_paging_enabled to SysemuCPUOps' 016/27:[0084] [FC] 'cpu: Restrict "hw/core/sysemu-cpu-ops.h" to target/cpu.c' 017/27:[down] 'linux-user: Remove dead code' 018/27:[down] 'gdbstub: Remove watchpoint dead code in gdbserver_fork()' 019/27:[down] 'target/arm/internals: Fix code style for checkpatch.pl' 020/27:[down] 'target/arm: Move code blocks around' 021/27:[down] 'target/arm: Refactor some function bodies' 022/27:[down] 'target/arm: Restrict watchpoint code to system emulation' 023/27:[down] 'target/i386: Restrict watchpoint code to system emulation' 024/27:[down] 'accel/tcg/cpu-exec: Restrict watchpoint code to system emulati= on' 025/27:[down] 'cpu: Remove watchpoint stubs for user emulation' 026/27:[down] 'cpu: Fix code style for checkpatch.pl' 027/27:[down] 'cpu: Move sysemu specific declarations to 'sysemu-cpu-ops.h'' Regards, Phil.
