2009-09-11qdev: Fix i6300 upcastMarkus Armbruster
Use DO_UPCAST() instead of container_of() to go from PCIDevice to I6300State. This ensures that PCIDevice is the first member of struct I6300State. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-11VirtIO: Fix QEMU crash during Windows PNP testsYan Vugenfirer
Hello, In some cases bus driver can deassert "bus master" bit in PCI command register. The driver will no longer be able to update related registers in the device. Eventually it will cause QEMU to exit in "virtqueue_num_heads" function. Attached path that fixes the described issue. Best regards, Yan Vugenfirer. >From 3fdafbdfad676ec8479dc073cff70bf356868bfe Mon Sep 17 00:00:00 2001 From: Yan Vugenfirer <yvugenfi@redhat.com> Date: Tue, 8 Sep 2009 10:08:14 -0400 Subject: [PATCH] VirtIO: Fix QEMU crash during Windows PNP tests Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-11virtio-blk: add volatile writecache featureChristoph Hellwig
Add a new VIRTIO_BLK_F_WCACHE feature to virtio-blk to indicate that we have a volatile write cache that needs controlled flushing. Implement a VIRTIO_BLK_T_FLUSH operation to flush it. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-09-11block: add enable_write_cache flagChristoph Hellwig
Add a enable_write_cache flag in the block driver state, and use it to decide if we claim to have a volatile write cache that needs controlled flushing from the guest. The flag is off if cache=writethrough is defined because O_DSYNC guarantees that every write goes to stable storage, and it is on for cache=none and cache=writeback. Both scsi-disk and ide now use the new flage, changing from their defaults of always off (ide) or always on (scsi-disk).

2009-09-11qemu: make virtio-blk PCI compliant by defaultMichael S. Tsirkin
commit bf011293faaa7f87e4de83185931e7411b794128 made virtio-blk-pci not PCI-compliant, since it makes region 0 (which is an i/o region) size > 256, and, since PCI 2.1, i/o regions are limited to 256 bytes size. When the ATA serial number feature is off, which is the default, make the device spec compliant again, by making region 0 smaller. Signed-off-by: Michael S.

2009-09-11virtio-blk: Use bdrv_aio_multiwriteKevin Wolf

2009-09-10qdev: simplify isa irq assignmentsGerd Hoffmann
isa-bus owns the isa irqs now, so it can hand them out directly. There is no need for the separate isa_connect_irqs step, drop it. Also hard-code isa interrupts which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-09-10qdev: drop iobase properties from isa busGerd Hoffmann
Lot of ISA devices work at fixed addresses, so having iobase as bus property doesn't make much sense. Devices which can have different iobases will get a device property. Also simply hard-code stuff which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2009-09-09Fix VMSTATE_PCI_DEVICE versionJuan Quintela
PCI device entries have to have a default version, not 2, because they are used in the midle of other structures that can have _any_ version number. We can't use proper versioning here until we have SubSections support. Why we didn't noticed before? Because in a PC, the only device ported with a version less that 2 is piix_pm, and for that one, default pci values are right. If you use a virtio-console, you will see that its state it is not loaded back. Thanks to Amit Shah for reporting the problem and help debug the fix.

2009-09-09don't call cpu_sychronize_state from reset handlersGlauber Costa
Doing this will make the vcpu ioctl be issued from the I/O thread, instead of cpu thread. The correct behaviour is to call it from within the cpu thread, as soon as we are ready to go. Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-09RTC polling mode brokenBernhard Kauer
The RTC emulation does not set the IRQ flags independent of the IRQ enable bits. The original MC146818A datasheet from 1984 notes: "flag bits in Register C [...] are set independent of the state of the corresponding enable bits in Register B" Similar sections can be found in newer documentation e.g. in rtc82885. Qemu and Bochs set the IRQ flags only if they are enabled, which breaks drivers polling on them. The following patch corrects this for the update-ended-flag in Qemu only. It does not fix the handling of the other flags. Signed-off-by: Bernhard Kauer <kauer@tudos.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Full coverage with properties and everything. You can add virtual usb sticks this way now: -drive if=none,id=pendrive,path=/some/where -device usb-storage,drive=pendrive -usbdevice disk:/path/to/image continues to work.

You can add a OHCI USB Controller to your virtual pc now using '-device pci-ohci'.
