Move target-* CPU file into a target/ folder

2016-12-20T20:52:12+00:00

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.

log: Add locking to large logging blocks

2016-11-01T16:29:03+00:00

Reuse the existing locking provided by stdio to keep in_asm, cpu, op, op_opt, op_ind, and out_asm as contiguous blocks. While it isn't possible to interleave e.g. in_asm or op_opt logs because of the TB lock protecting all code generation, it is possible to interleave cpu logs, or to interleave a cpu dump with an out_asm dump. For mingw32, we appear to have no viable solution for this. The locking functions are not properly exported from the system runtime library.

target-alpha: Emulate LL/SC using cmpxchg helpers

2016-10-26T15:29:02+00:00

Emulating LL/SC with cmpxchg is not correct, since it can suffer from the ABA problem. However, portable parallel code is written assuming only cmpxchg which means that in practice this is a viable alternative. Signed-off-by: Richard Henderson

target-alpha: Introduce MMU_PHYS_IDX

2016-10-26T15:29:02+00:00

Rather than using helpers for physical accesses, use a mmu index. The primary cleanup is with store-conditional on physical addresses. Signed-off-by: Richard Henderson

exec: move cpu_exec_init() calls to realize functions

2016-10-24T19:29:16+00:00

Modify all CPUs to call it from XXX_cpu_realizefn() function. Remove all the cannot_destroy_with_object_finalize_yet as unsafe references have been moved to cpu_exec_realizefn(). (tested with QOM command provided by commit 4c315c27) for arm: Setting of cpu->mp_affinity is moved from arm_cpu_initfn() to arm_cpu_realizefn() as setting of cpu_index is now done in cpu_exec_realizefn(). To avoid to overwrite an user defined value, we set it to an invalid value by default, and update it in realize function only if the value is still invalid.

target-*: Clean up cpu.h header guards

2016-07-12T14:19:16+00:00

Most of them use guard symbols like CPU_$target_H, but we also have __MIPS_CPU_H__ and __TRICORE_CPU_H__. They all upset scripts/clean-header-guards.pl. The script dislikes CPU_$target_H because they don't match their file name (they should, to make guard collisions less likely). The others are reserved identifiers. Clean them all up: use guard symbol $target_CPU_H for target-$target/cpu.h. Signed-off-by: Markus Armbruster Reviewed-by: Richard Henderson

Fix confusing argument names in some common functions

2016-07-12T12:06:08+00:00

There are functions tlb_fill(), cpu_unaligned_access() and do_unaligned_access() that are called with access type and mmu index arguments. But these arguments are named 'is_write' and 'is_user' in their declarations. The patches fix the arguments to avoid a confusion.
