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.

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.

Clean up header guards that don't match their file name

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

Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones. Signed-off-by: Markus Armbruster Reviewed-by: Richard Henderson

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

target-*: Don't redefine cpu_exec()

2016-06-29T12:03:47+00:00

This function needs to be converted to QOM hook and virtualised for multi-arch. This rename interferes, as cpu-qom will not have access to the renaming causing name divergence. This rename doesn't really do anything anyway so just delete it.

exec: [tcg] Track which vCPU is performing translation and execution

2016-06-20T14:30:01+00:00

Information is tracked inside the TCGContext structure, and later used by tracing events with the 'tcg' and 'vcpu' properties. The 'cpu' field is used to check tracing of translation-time events ("*_trans"). The 'tcg_env' field is used to pass it to execution-time events ("*_exec").

cpu: move exec-all.h inclusion out of cpu.h

exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini

tb: consistently use uint32_t for tb->flags

2016-05-13T00:06:40+00:00

We are inconsistent with the type of tb->flags: usage varies loosely between int and uint64_t. Settle to uint32_t everywhere, which is superior to both: at least one target (aarch64) uses the most significant bit in the u32, and uint64_t is wasteful. Compile-tested for all targets.

include/qemu/osdep.h: Don't include qapi/error.h

2016-03-22T21:20:15+00:00

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini
