2010-02-06PCI: fix multiple bridge problemsBlue Swirl
When several PCI bridges were in use, monitor command "info pci" would enter into infinite loop. Buses behind the bridge were not discoverable because secondary and subordinate bus numbers were not used properly. Other buses were not found because bus search terminated on first miss.

2010-02-03KVM: Make vmport KVM-compatibleJan Kiszka
The vmport "device" accesses the VCPU registers, so it requires proper cpu_synchronize_state. Add it to vmport_ioport_read, which also synchronizes vmport_ioport_write. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2010-02-03qdev: Add rudimentary help for property valueMarkus Armbruster
This provides the same information as reverted commit 2ba6edf0. Not much, just better than nothing. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03qdev: Add help for device propertiesMarkus Armbruster
Option "-device DRIVER,?" and monitor command "device_add DRIVER,?" print the supported properties instead of creating a device. The former also terminates the program. This is commit 2ba6edf0 (just reverted) done right. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03Revert "qdev: Add help for device properties"Markus Armbruster
This reverts commit 2ba6edf0dd740166632df80caa85992b20791a68. The commit has two issues: * When it runs from the monitor, e.g. "device_add e1000,?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03Revert "qdev: Add help for property value"Markus Armbruster
This reverts commit 922910ce42d15bdb7c2347436b1b5798b5401de4. The commit has four issues: * When it runs from the monitor, e.g. "device_add e1000,mac=?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,mac=?". * It has an undocumented side effect on -global: "-global e1000.mac=?" prints help, but only when we actually add an e1000 device. * It does not work for properties that accept the value "?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03qdev: Fix exit code for -device ?Markus Armbruster
Help was shoehorned into device creation, qdev_device_add(). Since help doesn't create a device, it returns NULL, which looks to callers just like failed device creation. Monitor handler do_device_add() doesn't care, but main() exits unsuccessfully. Move help out of device creation, into new qdev_device_help().

2010-01-29virtio-blk: Fix error cases which ignored rerror/werrorKevin Wolf
If an I/O request fails right away instead of getting an error only in the callback, we still need to consider rerror/werror. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-29virtio-blk: Fix restart after read errorKevin Wolf
Current code assumes that only write requests are ever going to be restarted. This is wrong since rerror=stop exists. Instead of directly starting writes, use the same request processing as used for new requests. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-29virtio_blk: Factor virtio_blk_handle_request outKevin Wolf

2010-01-29cirrus: Properly re-register cirrus_linear_io_addr on vram unmapJan Kiszka
This fixes CONFIG_FB_CIRRUS for Linux guests and probably much more: When switching away from linearly mapped vram, we also have to restore the I/O handlers for the LFB.

2010-01-27sparc64: reimplement tick timers v4Igor V. Kovalenko
sparc64 timer has tick counter which can be set and read, and tick compare value used as deadline to fire timer interrupt. The timer is not used as periodic timer, instead deadline is set each time new timer interrupt is needed. v3 -> v4: - coding style v2 -> v3: - added missing timer debug output macro - CPUTimer struct and typedef moved to cpu.h - change CPU_SAVE_VERSION to 6, older save formats not supported v1 -> v2: - new conversion helpers cpu_to_timer_ticks and timer_to_cpu_ticks - save offset from clock source to implement cpu_tick_set_count - renamed struct sun4u_timer to CPUTimer - load and save cpu timers v0 -> v1: - coding style Signed-off-by: Igor V.

2010-01-27pflash: Buffer block writesEdgar E. Iglesias
Buffer block writes to avoid flushing every word access onto backing storage device. This significantly speeds up flash emulation for flashes connected through an 8 or 16-bit bus combined with backing storage (-pflash). Signed-off-by: Edgar E. Iglesias <edgar.iglesias@petalogix.com>
2010-01-26virtio: Add memory statistics reporting to the balloon driverAdam Litke
When using ballooning to manage overcommitted memory on a host, a system for guests to communicate their memory usage to the host can provide information that will minimize the impact of ballooning on the guests. The current method employs a daemon running in each guest that communicates memory statistics to a host daemon at a specified time interval. The host daemon aggregates this information and inflates and/or deflates balloons according to the level of host memory pressure. This approach is effective but overly complex since a daemon must be installed inside each guest and coordinated to communicate with the host. A simpler approach is to collect memory statistics in the virtio balloon driver and communicate them directly to the hypervisor.

2010-01-26win32: pair qemu_memalign() with qemu_vfree()Herve Poussineau
Win32 suffers from a very big memory leak when dealing with SCSI devices. Each read/write request allocates memory with qemu_memalign (ie VirtualAlloc) but frees it with qemu_free (ie free). Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks. Signed-off-by: Herve Poussineau <hpoussin@reactos.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-26PCI: fix bridge configurationBlue Swirl

2010-01-26ide save/restore current transfer fieldsMarcelo Tosatti
If migration takes place between write of the bmdma address register and write of the command register (to initiate DMA), the destination will not properly start the DMA op, hanging the guest: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.00: cmd c8/00:16:41:00:00/00:00:00:00:00/e0 tag 0 dma 11264 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } Fix by sending current transfer information in the migration data. We need to update ide version to 4 for this to work. As we don't have subsectios, we need to chain the update increase until vmstate_ide_pci (quintela) Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-26PCI: do_pci_info(): PCI bridge devices supportLuiz Capitulino
This commit completes the do_pci_info() conversion to QObject by adding support to PCI bridge devices. This is done by recursively adding devices in the "pci_bridge" key. IMPORTANT: This code is being added separately because I could NOT test it properly. According to Michael Tsirkin, it depends on ultrasparc and it would take time to do the proper setup.

2010-01-26PCI: Convert pci_info() to QObjectLuiz Capitulino
The returned QObject is a QList of all buses. Each bus is represented by a QDict, which has a key with a QList of all PCI devices attached to it. Each device is represented by a QDict. As has happended to other complex conversions, it's hard to split this commit as part of it are new functions which are called by each other. IMPORTANT: support for printing PCI bridge attached devices is NOT part of this commit, it's going to be added by the next commit, as it's untested.

2010-01-26qdev: Add help for property valueStefan Weil
When called with property value "?", a help text will be printed (instead of an error message). This is useful for command lines like qemu -device e1000,mac=? and is already standard for other command line options. A better help text could be provided by extending the Property structure with a desc field. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-01-24Musicpal: Fix descriptor walk in eth_sendJan Kiszka
Commit 930c86820e introduced a regression to eth_send: eth_tx_desc_put manipulates the host's tx descriptor copy before writing it back, but two lines down the descriptor is evaluated again, leaving us with an invalid next address if host and guest endianness differ.
