* Move macro QEMU_GNUC_PREREQ to compiler.hStefan Weil2011-09-231-7/+0
| | | | | | | | | | | | | The macro is compiler specific and does not depend on the operating system. Move macro QEMU_GNUC_PREREQ from osdep.h to compiler.h and use it to simplify existing code. host-utils.h uses this macro, so it now needs compiler.h instead of osdep.h.

* w64: Add definition of FMT_pidStefan Weil2011-08-211-0/+2
| | | | | | | | | For mingw-w64, pid_t is _pid_t which is __int64, so this platform needs its own definition of FMT_pid. Reviewed-by: Andreas Färber <andreas.faerber@web.de> Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* Introduce format string for pid_tAndreas Färber2011-06-151-0/+6
| | | | | | | | | | | | | | | | | | | | | BeOS and Haiku on i386 use long for 32-bit types, including pid_t. Using %d with pid_t therefore results in a warning. Unfortunately POSIX:2008 does not define a PRId* string for pid_t. In some places pid_t was previously casted to long and %ld hardcoded. The predecessor of this patch added another upcast for the simpletrace filename but was not applied to date. Since new uses of pid_t with %d keep creeping in, let's instead define an OS-dependent format string and use that consistently.

* Darwin: Fix compilation warning regarding the deprecated daemon() functionAlexandre Raymond2011-06-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | Changes since v1: create a wrapper function named qemu_daemon() in oslib-posix.c instead of putting the OS specific workaround in qemu-nbd.c directly. On OSX >= 10.5, daemon() is deprecated, resulting in the following warning: ----8<---- qemu-nbd.c: In function ‘main’: qemu-nbd.c:371: warning: ‘daemon’ is deprecated (declared at /usr/include/stdlib.h:289) ----8<---- The following trick, used in mDNSResponder, takes care of this warning: http://www.opensource.apple.com/source/mDNSResponder/mDNSResponder-258.18/mDNSPosix/PosixDaemon.c On OSX, it temporarily renames the daemon() function before including stdlib.h and declares it manually as an extern function. This way, the compiler does not see the declaration from stdlib.h and thus does not display the warning.

* bitmap: add a generic bitmap and bitops libraryCorentin Chary2011-02-231-0/+4
| | | | | | | | | | | | | | | | | | Add most used bitmap and bitops functions into bitmap.c and bitops.c. Theses functions are mostly copied from Linux kernel source. Some of these functions are already redefined in the VNC server. Some of them could be used for some block stuff. The yet yo be submitted NUMA work also need bitmaps. bitops_ffsl() and bitops_flsl() are here because bitops/bitmap works on unsigned long, not int, and we can't use current code because: * ffs only works on int * qemu_fls only works on int * ffsl is a GNU extension Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* Introduce qemu_madvise()Andreas Färber2010-09-251-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vl.c has a Sun-specific hack to supply a prototype for madvise(), but the call site has apparently moved to arch_init.c. Haiku doesn't implement madvise() in favor of posix_madvise(). OpenBSD and Solaris 10 don't implement posix_madvise() but madvise(). MinGW implements neither. Check for madvise() and posix_madvise() in configure and supply qemu_madvise() as wrapper. Prefer madvise() over posix_madvise() due to flag availability. Convert all callers to use qemu_madvise() and QEMU_MADV_*. Note that on Solaris the warning is fixed by moving the madvise() prototype, not by qemu_madvise() itself. It helps with porting though, and it simplifies most call sites. v7 -> v8: * Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl. v6 -> v7: * Adopt madvise() rather than posix_madvise() semantics for returning errors. * Use EINVAL in place of ENOTSUP. v5 -> v6: * Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID. Spotted by Blue Swirl. v4 -> v5: * Introduce QEMU_MADV_INVALID, suggested by Alexander Graf. Note that this relies on -1 not being a valid advice value. v3 -> v4: * Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl. This will currently break the check in kvm-all.c by calling madvise() with a supported flag, which will not fail. Ideas/patches welcome. v2 -> v3: * Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf. * Add configure check for madvise(), too. Add defines to Makefile, not QEMU_CFLAGS. Convert all callers, untested. Suggested by Blue Swirl. * Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf. * Display configure check results. v1 -> v2: * Don't rely on posix_madvise() availability, add qemu_madvise(). Suggested by Blue Swirl.
