2011-02-07block: enable in_use flagMarcelo Tosatti3-0/+8
Set block device in use during block migration, disallow drive_del and bdrv_truncate for in use devices. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit 8591675f44929a9e4b5d3a5fd702a4b6d41c7903)
2011-02-07Add flag to indicate external users to block deviceMarcelo Tosatti3-0/+14
Certain operations such as drive_del or resize cannot be performed while external users (eg. block migration) reference the block device. Add a flag to indicate that.

2011-02-07block-migration: add reference to target DriveInfoMarcelo Tosatti1-0/+3
So that ejection of attached device by guest does not free data in use by block migration instance.

2011-02-07blockdev: add refcount to DriveInfoMarcelo Tosatti3-4/+20
The host part of a block device can be deleted with in progress block migration. To fix this, add a reference count to DriveInfo, freeing resources on last reference.

2011-02-07ahci: make number of ports runtime determinedAlexander Graf3-16/+26
Different AHCI controllers have a different number of ports, so the core shouldn't care about the amount of ports available. This patch makes the number of ports available to the AHCI core runtime configurable, allowing us to have multiple different AHCI implementations with different amounts of ports. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit 2c4b9d0ea42c27ec2112e437a0fa954afe73bd23)
2011-02-07ahci: Implement HBA resetAlexander Graf1-1/+4
The ahci code was missing its soft reset functionality. This wasn't really an issue for Linux guests, but Windows gets confused when the controller doesn't reset when it tells it so. Using this patch I can now successfully boot Windows 7 from AHCI using AHCI enabled SeaBIOS. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit 760c3e44d3a1d8a7e9d22f0429b1805d1c688178)
2011-02-07ahci: send init d2h fis on fis enableAlexander Graf2-7/+32
The drive sends a d2h init fis on initialization. Usually, the guest doesn't receive fises yet at that point though, so the delivery is deferred. Let's reflect that by sending the init fis on fis receive enablement. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit 87e62065bb5e0e544e45e6935e3ac2b053fe446e)
2011-02-07ahci: split ICH and AHCI even moreAlexander Graf2-112/+88
Sebastian's patch already did a pretty good job at splitting up ICH-9 AHCI code and the AHCI core. We need some more though. Copyright was missing, the lspci dump belongs to ICH-9, we don't need the AHCI core to have its own qdev device duplicate. So let's split them a bit more in this patch, making things easier to read an understand. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com> (cherry picked from commit 7fb6577b130c615e42e1ccf8dad69c27c3eef085)

2011-02-07ahci: split ICH9 from coreSebastian Herbszt4-301/+375
There are multiple ahci devices out there. The currently implemented ich-9 is only one of the many. So let's split that one out into a separate file to stress the difference.

2011-02-07block/vdi: Fix wrong size in conditionally used memset, memcmpStefan Weil1-2/+2
Error report from cppcheck: block/vdi.c:122: error: Using sizeof for array given as function argument returns the size of pointer. block/vdi.c:128: error: Using sizeof for array given as function argument returns the size of pointer. Fix both by setting the correct size. The buggy code is only used when QEMU is build without uuid support. The bug is not critical, so there is no urgent need to apply it to old versions of QEMU.

2011-02-04ioapic: Add support for qemu-kvm's vmstate v2Jan Kiszka1-1/+2
qemu-kvm carries the IOAPIC base address in its v2 vmstate. We only support the default base address so far, and saving even that in the device state was rejected. Add a padding field to be able to read qemu-kvm's old state, but increase our version to 3, indicating that we are not saving a valid address. This also gives downstream the chance to change to stop evaluating the base_address and move to v3 as well.

2011-02-04vnc: qemu can die if the client is disconnected while updating screenCorentin Chary1-0/+4
agraf reported that qemu_mutex_destroy(vs->output_mutex) while failing in vnc_disconnect_finish(). It's because vnc_worker_thread_loop() tries to unlock the mutex while not locked.

2011-02-04ui/sdl: Fix handling of caps lock and num lock keysStefan Weil1-0/+8
Starting with SDL version 1.2.14, caps lock and num lock keys will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in the environment. The new code sets the environment unconditionally (it won't harm old versions which do not know it). The workaround for SDL_KEYUP is only compiled with old SDL versions. A similar patch without handling of old SDL versions was already published by Benjamin Drung for Ubuntu.

2011-02-04Unify alarm deadline computationPaolo Bonzini1-17/+11
This patch shows how using the correct formula for qemu_next_deadline_dyntick can simplify the code of host_alarm_handler and eliminate useless duplication.

2011-02-04Correct alarm deadline computationPaolo Bonzini1-4/+11
When the QEMU_CLOCK_HOST clock was added, computation of its deadline was added to qemu_next_deadline, which is correct but incomplete. I noticed this by reading the very convoluted rules whereby qemu_next_deadline_dyntick is computed, which miss QEMU_CLOCK_HOST when use_icount is true. This patch inlines qemu_next_deadline into qemu_next_deadline_dyntick, and then corrects the logic to skip only QEMU_CLOCK_VIRTUAL when use_icount is true.

2011-02-04savevm: fix corruption in vmstate_subsection_load().Yoshiaki Tamura1-1/+9
Although it's rare to happen in live migration, when the head of a byte stream contains 0x05 which is the marker of subsection, the loader gets corrupted because vmstate_subsection_load() continues even the device doesn't require it. This patch adds a checker whether subsection is needed, and skips following routines if not needed.

2011-02-01vhost: force vhost off for non-MSI guestsmst@redhat.com9-13/+52
When MSI is off, each interrupt needs to be bounced through the io thread when it's set/cleared, so vhost-net causes more context switches and higher CPU utilization than userspace virtio which handles networking in the same thread. We'll need to fix this by adding level irq support in kvm irqfd, for now disable vhost-net in these configurations. Added a vhostforce flag to force vhost-net back on. Signed-off-by: Michael S.
