      Introduce qemu_madvise() · e78815a5
      Andreas Färber 提交于
      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.

      powerpc: Make the decr interrupt type overridable · d63cb48d
      Edgar E. Iglesias 提交于
      Make it possible for boards to override the kind of interrupt
      to be signaled when the decr timer hits. The 405's signal PIT
      interrupts while the 440's signal DECR.
