2011-01-14target-sh4: switch sh4 to softfloatAurelien Jarno
We need to be able to catch exceptions correctly and thus enable softfloat on SH4. As all machines except i386 and x86_64 are using softfloat, make it the default and change the case to detect i386 and x86_64. Note that CRIS doesn't have an FPU, so it can be configured with both softfloat-native and softfloat. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14configure: fix broken testAurelien Jarno
Since commit d1807a4f836c27f6dc7061e53a834dd27f78e46a ./configure tries to test files and directories with "test -f", which only test for regular files. Test with "test -e", which looks for any kind of files. This unbreak the configure script when not using a separate object directory. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-14do not pass bogus $(SRC_PATH) include paths to cc during configurePaolo Bonzini
Non-existent -I paths are dropped silently by the compiler, but still it is not polite to pass bogus options. Configure-time tests do not need any include files from the source path, so only include -I flags at make time (when they're properly expanded).

2011-01-14test cc with the complete set of chosen flagsPaolo Bonzini
The "test the C compiler works ok" comes before a bunch of flags are added for --cpu or just depending on the host.

2010-11-21Add a DTrace tracing backend targetted for SystemTAP compatabilityDaniel P. Berrange
This introduces a new tracing backend that targets the SystemTAP implementation of DTrace userspace tracing. The core functionality should be applicable and standard across any DTrace implementation on Solaris, OS-X, *BSD, but the Makefile rules will likely need some small additional changes to cope with OS specific build requirements. This backend builds a little differently from the other tracing backends. Specifically there is no 'trace.c' file, because the 'dtrace' command line tool generates a '.o' file directly from the dtrace probe definition file. The probe definition is usually named with a '.d' extension but QEMU uses '.d' files for its external makefile dependancy tracking, so this uses '.dtrace' as the extension for the probe definition file. The 'tracetool' program gains the ability to generate a trace.h file for DTrace, and also to generate the trace.d file containing the dtrace probe definition. Example usage of a dtrace probe in systemtap looks like: probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } * .gitignore: Ignore trace-dtrace.* * Makefile: Extra rules for generating DTrace files * Makefile.obj: Don't build trace.o for DTrace, use trace-dtrace.o generated by 'dtrace' instead * tracetool: Support for generating DTrace data files Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Daniel P.

2010-11-01Add Intel HD Audio support to qemu.Gerd Hoffmann
This patch adds three devices to qemu: intel-hda Intel HD Audio Controller, the PCI device. Provides a HDA bus. Emulates ICH6 at the moment. Adding a ICH9 PCIE variant shouldn't be hard. hda-duplex HDA Codec. Attaches to the HDA bus. Supports 16bit stereo, rates 16k -> 96k, playback, recording and volume control (with CONFIG_MIXEMU=y). hda-output HDA Codec without recording support. Subset of the hda-duplex codec. Use this if you don't want your guests access your mic. Usage: add '-device intel-hda -device hda-duplex' to your command line. Tested guests: * Linux works. * Win7 works. * DOS (mpxplay) works. * WinXP doesn't work. [ v2 changes ] * Fixed endianess, big endian hosts work now. * Fixed some emulation bugs. * Added immediate command emulation. * Added vmstate support. * Make it behave like all other sound card drivers: - can be configured via '--audio-card-list=hda' - can be added to a VM using '-soundhw hda' * Code style fixups. * Zapped guest-triggerable asserts. * Handle partial reads/writes of audio data correctly.

2010-09-25Introduce qemu_madvise()Andreas Färber
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.
