+API hierarchy
+=============
+
+1) QEMU common API
+
+ |-------------------------------|
+ | C99 API |
+ | - <stdio.h> <stdlib.h> ... |
+ |-------------------------------|
+ | QEMU basic API |
+ | - include/qemu/* |
+ |-------------------------------|
+ | QEMU utility/helper API |
+ | - block |
+ | - disas |
+ | - migration |
+ | - monitor |
+ | - net |
+ | - qapi |
+ | - ... |
+ |-------------------------------|
+
+2) CPUArchState API
+
+ |-----------------------------------------------------------------------|
+ | qom/Object | QEMU common API |
+ |--------------| - Linux API |
+ | - QEMU basic API |
+ | - QEMU utility/helper API |
+ |-----------------------------------------------------------------------|
+ | qdev/DeviceState |
+ |-----------------------------------------------------------------------|
+ | Create new file? | sysemu/kvm.h | hw/xen/xen.h |
+ | exec/cpu-exec.h? | | |
+ |------------------------------------------------|
+ | TODO: consider to abstract vcpu here? |
+ | include/qom/vcpu.h? |
+ |-----------------------------------------------------------------------|
+ | qom/CPUState |
+ |-----------------------------------------------------------------------|
+ | target-xxx/CPUArchState | sysemu/sysemu.h |
+ |-----------------------------------------------------------------------|
+
+ cpu-exec.h is for one (tcg) of the 3 accelerators: tcg, kvm and xen.
+
+3) Memory API
+
+ |--------------------------------------------------------------|
+ | linux-user | softmmu |
+ | gueust virtual address | guest physical address |
+ | | guest virtual address |
+ | | |
+ | | --------------------------------|
+ | | | Memory modelling |
+ | | | |
+ | | | MemoryRegion | RAMBlock |
+ | | | memory.h | |
+ | | --------------------------------|
+ | | | softmmu API |
+ | | | - include/exec/softmmu*.h |
+ | | | - include/exec/cputlb.h |
+ |--------------------------------------------------------------|
+ | memory load/store API |
+ | include/exec/cpu-common.h |
+ |--------------------------------------------------------------|
+
+4) exec API
+
+ architecture-independent | architecture
+ | specific
+ |------------------| |
+ | memory | |
+ | load/store API | |
+ | cpu-common.h | |
+ |-----------------------------------------------------|---------------|
+ | tcg framework | tcg frontend |
+ | tcg/tcg*.h | |
+ |------------------|---------------|---------------|
+ | TranslationBlock | |
+ | translate.h | |
+ |-------------------------------------|---------------|---------------|
+ | | misc cpu API | misc cpu API |
+ | include/exec/exec-all.h | cpu-common.h | cpu-all.h |
+ |-------------------------------------|---------------|---------------|
+
+ include/exec includes:
+ - Memory API
+ - TranslationBlock API
+ - misc cpu API (both architecture-independent and architecture-specific)
+
+ include/exec/cpu-all.h is for architecture-specific, it's only included
+ in target-xxx/* files.
