* osdep: Move default qemu_hw_version() value to a macroEduardo Habkost2016-05-231-0/+9

* exec.c: Ensure right alignment also for file backed ramDominik Dingel2016-05-231-0/+13
| | | | | | | | | | | | | | While in the anonymous ram case we already take care of the right alignment such an alignment gurantee does not exist for file backed ram allocation. Instead, pagesize is used for alignment. On s390 this is not enough for gmap, as we need to satisfy an alignment up to segments.

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.

* icount: decouple warp callsPavel Dovgalyuk2016-03-151-4/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | qemu_clock_warp function is called to update virtual clock when CPU is sleeping. This function includes replay checkpoint to make execution deterministic in icount mode. Record/replay module flushes async event queue at checkpoints. Some of the events (e.g., block devices operations) include interaction with hardware. E.g., APIC polled by block devices sets one of IRQ flags. Flag to be set depends on currently executed thread (CPU or iothread). Therefore in replay mode we have to process the checkpoints in the same thread as they were recorded. qemu_clock_warp function (and its checkpoint) may be called from different thread. This patch decouples two different execution cases of this function: call when CPU is sleeping from iothread and call from cpu thread to update virtual clock. First task is performed by qemu_start_warp_timer function. It sets warp timer event to the moment of nearest pending virtual timer. Second function (qemu_account_warp_timer) is called from cpu thread before execution of the code. It advances virtual clock by adding the length of period while CPU was sleeping.

* osdep: add wrappers for socket functionsDaniel P. Berrange2016-03-101-14/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The windows socket functions look identical to the normal POSIX sockets functions, but instead of setting errno, the caller needs to call WSAGetLastError(). QEMU has tried to deal with this incompatibility by defining a socket_error() method that callers must use that abstracts the difference between WSAGetLastError() and errno. This approach is somewhat error prone though - many callers of the sockets functions are just using errno directly because it is easy to forget the need use a QEMU specific wrapper. It is not always immediately obvious that a particular function will in fact call into Windows sockets functions, so the dev may not even realize they need to use socket_error(). This introduces an alternative approach to portability inspired by the way GNULIB fixes portability problems. We use a macro to redefine the original socket function names to refer to a QEMU wrapper function. The wrapper function calls the original Win32 sockets method and then sets errno from the WSAGetLastError() value. Thus all code can simply call the normal POSIX sockets APIs are have standard errno reporting on error, even on Windows. This makes the socket_error() method obsolete. We also bring closesocket & ioctlsocket into this approach. Even though they are non-standard Win32 names, we can't wrap the normal close/ioctl methods since there's no reliable way to distinguish between a file descriptor and HANDLE in Win32.

* osdep: fix socket_error() to work with Mingw64Daniel P. Berrange2016-03-101-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically QEMU has had a socket_error() macro that was defined to map to WSASocketError(). The os-win32.h header file would define errno constants that mapped to the WSA error constants. This worked fine with Mingw32 since its header files never defined any errno values, nor did it even provide an errno.h. So callers of socket_error() could match on traditional Exxxx constants and it would all "just work". With Mingw64 though, things work rather differently. First there is an errno.h file which defines all the traditional errno constants you'd expect from a UNIX platform. There is then a winerror.h which defined the WSA error constants. Crucially the WSAExxxx errno values in winerror.h do not match the Exxxx errno values in error.h. If QEMU had only imported winerror.h it would still work, but the qemu/osdep.h file unconditionally imports errno.h. So callers of socket_error() will get now WSAExxxx values back and compare them to the Exxx constants. This will always fail silently at runtime. To solve this QEMU needs to stop assuming the WSAExxxx constant values match the Exxx constant values. Thus the socket_error() macro is turned into a small function that re-maps WSAExxxx values into Exxx. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Daniel P.

This commit was created with scripts/clean-includes. NB: If this commit breaks compilation for your out-of-tree patchseries or fork, then you need to make sure you add #include "qemu/osdep.h" to any new .c files that you have.

For the former, we must also include config-target.h so that the .c files see the necessary CONFIG_ constants.

* | osdep.h: Define macros for the benefit of C++ before C++11Peter Maydell2016-02-231-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For C++ before C++11, <stdint.h> requires definition of the macros __STDC_CONSTANT_MACROS, __STDC_LIMIT_MACROS and __STDC_FORMAT_MACROS in order to enable definition of various macros by the header file. Define these in osdep.h, so that we get the right header file definitions whether osdep.h is being used by plain C, C++11 or older C++. In particular libvixl's header files depend on this and won't compile if osdep.h is included before them otherwise.

As a consequence, check_throttle_config() becomes redundant and can be replaced with throttle_is_valid().

| | | | | | | | | | | | | The right place for "work around issues with system headers" code is osdep.h. Move the workaround for OSX's stdlib.h emitting a deprecation warning for daemon() to that header. This also fixes a problem where running clean-includes on oslib-posix.c would erroneously remove the #include <stdlib.h> from it, breaking the workaround.

* build: Don't redefine 'inline'Eric Blake2016-02-161-12/+0Star
| | | | | | | | | | | | | | | | | | | | | | | Actively redefining 'inline' is wrong for C++, where gcc has an extension 'inline namespace' which fails to compile if the keyword 'inline' is replaced by a macro expansion. This will matter once we start to include "qemu/osdep.h" first from C++ files, depending also on whether the system headers are new enough to be using the gcc extension. But rather than just guard things by __cplusplus, let's look at the overall picture. Commit df2542c737ea2 in 2007 defined 'inline' to the gcc attribute __always_inline__, with the rationale "To avoid discarded inlining bug". But compilers have improved since then, and we are probably better off trusting the compiler rather than trying to force its hand. So just nuke our craziness.
