2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-11-09intel-hda: fix codec addressing.Gerd Hoffmann
The HDA bus supports up to 15 codecs, with addresses 0 ... 14. We get that wrong in two places: * When handing out addresses we accept address 15 as valid. * The bitmasks for two registers (WAKEEN and STATESTS) don't have bit 14 set. This patch fixes it.

2010-11-09intel-hda: add msi supportGerd Hoffmann
This patch adds MSI support to the intel hda audio driver. It is enabled by default, use '-device intel-hda,msi=0' to disable it. [ v2: codestyle: add braces ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
2010-11-09intel-hda: update irq status on WAKEEN changes.Gerd Hoffmann
When the guest updates the WAKEEN register we must re-calculate the IRQ status. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
2010-11-09intel-hda: Honor WAKEEN bits.François Revol
HDA: Honor WAKEEN bits when deciding to raise an interrupt on codec status change. This prevents an interrupt storm with the Haiku HDA driver which does not handle codec status changes in the irq handler.

2010-11-09intel-hda: exit cleanupGerd Hoffmann
Add pci exit callback for the intel-hda device and cleanup properly. Also add an exit callback to the HDA bus implementation and make sure it is called on qdev_free(). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
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.
