* migration: Move the VMStateDescription typedef to typedefs.hMarkus Armbruster2019-08-161-1/+1
| | | | | | | | | | | | | | | We declare incomplete struct VMStateDescription in a couple of places so we don't have to include migration/vmstate.h for the typedef. That's fine with me. However, the next commit will drop migration/vmstate.h from a massive number of compiles. Move the typedef to qemu/typedefs.h now, so I don't have to insert struct in front of VMStateDescription all over the place then.

* qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster2019-04-181-2/+1Star
| | | | | | | | | | | | | | | | | | | | CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

* target: Simplify how the TARGET_cpu_list() printMarkus Armbruster2019-04-181-1/+1
| | | | | | | | | | | | | | | | | The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

| | | | | | | | | | | | | | | | | As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.

* accel/tcg: add size paremeter in tlb_fill()Laurent Vivier2018-01-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

| | | | | | | | | | | | | | | | | Switch the alpha target from the old unassigned_access hook to the new do_transaction_failed hook. This allows us to resolve a ??? in the old hook implementation. The only part of the alpha target that does physical memory accesses is reading the page table -- add a TODO comment there to the effect that we should handle bus faults on page table walks. (Since the palcode doesn't actually do anything useful on a bus fault anyway it's a bit moot for now.)

* Move target-* CPU file into a target/ folderThomas Huth2016-12-201-0/+518
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
