2011-12-20isa: give ISABus/ISADevice to isa_create(), isa_bus_irqs() and isa_get_irq() ↵Hervé Poussineau
functions NULL is a valid bus/device, so there is no change in behaviour. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-10-20migration: make *save_live return errorsJuan Quintela
Make *save_live() return negative values when there is one error, and updates all callers to check for the error. Signed-off-by: Juan Quintela <quintela@redhat.com>
2011-10-20migration: use qemu_file_get_error() return value when possibleJuan Quintela
Signed-off-by: Juan Quintela <quintela@redhat.com>
2011-10-20migration: rename qemu_file_has_error to qemu_file_get_errorJuan Quintela
Now the function returned errno, so it is better the new name. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Anthony Liguori <aliguori@us.ibm.com>
2011-10-20migration: change has_error to contain errno valuesJuan Quintela
We normally already have an errno value. When not, abuse EIO. Signed-off-by: Juan Quintela <quintela@redhat.com>
2011-09-23core: remove qemu_service_ioFrediano Ziglio
qemu_service_io was mainly an alias to qemu_notify_event, currently used only by PPC for timer hack, so call qemu_notify_event directly. Signed-off-by: Frediano Ziglio <freddy77@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-05-08Introduce -machine command option.Anthony PERARD
This option gives the ability to switch one "accelerator" like kvm, xen or the default one tcg. We can specify more than one accelerator by separate them by a colon. QEMU will try each one and use the first whose works. So, ./qemu -machine accel=xen:kvm:tcg which would try Xen support first, then KVM and finally TCG if none of the other works. By default, QEMU will use TCG. But we can specify another default in the global configuration file.

2010-12-02migration: stable ram block orderingMichael S. Tsirkin
This makes ram block ordering under migration stable, ordered by offset. This is especially useful for migration to exec, for debugging. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Tested-by: Jason Wang <jasowang@redhat.com>

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.

2010-10-27migration: don't segfault on invalid inputMichael S. Tsirkin
host_from_stream_offset returns NULL on error, return error instead of trying to use that address, to avoid segfault on invalid stream. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
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.

2010-08-19savevm: Reset last block info at beginning of each saveAlex Williamson
If we save more than once we need to reset the last block info or else only the first save has the actual block info and each subsequent save will only use continue flags, making them unloadable independently.

2010-07-06ramblocks: No more being lazy about duplicate namesAlex Williamson
Now that we have a working qemu_ram_free() and the primary runtime user of it has been updated, don't be lenient about duplicate id strings. We also shouldn't need to create them ondemand at the target. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-06savevm: Create a new continue flag to avoid resending block nameAlex Williamson
Allows us to compress the protocol a bit by setting a flag on the offset which indicates we're still working within the same block as last time. That way we can avoid sending the block name for every page. Suggested by Anthony Liguori.

2010-07-06savevm: Use RAM blocks for basis of migrationAlex Williamson
We don't want to assume a contiguous address space, so migrate based on RAM blocks instead of a fixed linear address map. This will allow us to have holes in the ram_addr_t namespace, so we can implement qemu_ram_free(). Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-06savevm: Migrate RAM based on name/offsetAlex Williamson
Synchronize RAM blocks with the target and migrate using name/offset pairs. This ensures both source and target have the same view of RAM and that we get the right bits into the right slot.

2010-07-06Remove uses of ram.last_offset (aka last_ram_offset)Alex Williamson
We currently need this either to allocate the next ram_addr_t for a new block, or for total memory to be migrated. Both of which we can calculate without need of this to keep us in a contiguous address space.

2010-06-01migration: Fix calculation of bytes_transferredPierre Riteau
When a page with all identical bytes is transferred, it is counted as a full page (TARGET_PAGE_SIZE) although only one byte is actually sent. Fix this by changing ram_save_block() to return the number of bytes sent instead of a boolean value. This makes bandwidth estimation, and consequently downtime estimation, more precise.

2010-03-29Refactor target specific handling, compile vl.c only onceBlue Swirl
Move target specific functions and RAM handling to arch_init.c. Add a flag to QEMUOptions structure to indicate for which architectures the option is allowed, check the flag in run time and remove conditional code in option handling. Now that no target dependencies remain, compile vl.c only once for all targets. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
