2014-09-30virtio-scsi-dataplane: Code to run virtio-scsi on iothreadFam Zheng2-1/+223
This implements the core part of dataplane feature of virtio-scsi. A few fields are added in VirtIOSCSICommon to maintain the dataplane status. These fields are managed by a new source file: virtio-scsi-dataplane.c. Most code in this file will run on an iothread, unless otherwise commented as in a global mutex context, such as those functions to start, stop and setting the iothread property. Upon start, we set up guest/host event notifiers, in a same way as virtio-blk does. The handlers then pop request from vring and call into virtio-scsi.c functions to process it. So we need to make sure make all those called functions work with iothread, too. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-09-30virtio-9p: fix virtio-9p child refcount in transportsGonglei1-0/+1
object_initialize() leaves the object with a refcount of 1. object_property_add_child() adds its own reference which is dropped again when the property is deleted.

2014-09-22ahci: properly shadow the TFD registerJohn Snow1-14/+28
In a real AHCI device, several S/ATA registers are mirrored or shadowed within the AHCI register set. These registers are not updated synchronously for each read access, but are instead updated after a Device-to-Host Register FIS packet is received. The D2H FIS contains the values from these registers on the device. In QEMU, by reaching directly into the device to grab these bits before they are "sent," we may introduce race conditions where unexpected values are present "before they are sent" which could cause issues for some guests, particularly if an attempt is made to read the PxTFD register prior to enabling the port, where incorrect values will be read. This patch also addresses the boot-time values for the PxTFD and PxSIG registers to bring them in line with the AHCI 1.3 specification. Lastly, several fields (PxTFD, PxSIG and PxSACT) are read-only, and any attempts to write to them should be ignored.

Further, the PCI capability pointer should always point to 0x80 in ICH9 devices, despite the fact that AHCI 1.3 specifies that it should be pointing to PMCAP (Which in this instance would be 0x70) to maintain adherence to the Intel data sheet specifications and real observed behavior.

2014-09-22ide/ahci: Check for -ECANCELED in aio callbacksFam Zheng2-0/+15
Before, bdrv_aio_cancel will either complete the request (like normal) and call CB with an actual return code, or skip calling the request (for example when the IO req is not submitted by thread pool yet). We will change bdrv_aio_cancel to do it differently: always call CB before return, with either [1] a normal req completion ret code, or [2] ret == -ECANCELED. So the callers' callback must accept both cases. The existing logic works with case [1], but not [2]. The simplest transition of callback code is do nothing in case [2], just as if the CB is not called by the bdrv_aio_cancel() call.

2014-09-22ide/atapi: Mark non-data commands as completeJohn Snow1-4/+3
When the command completion code in IDE and AHCI was unified to put all command completion inside of a callback, "cmd_done," we neglected to ensure that all AHCI/ATAPI command paths would eventually register as finished. for the PCI interface to IDE this is not a problem because cmd_done is a nop, but the AHCI implementation needs to send a D2H_REG_FIS and interrupt back to the guest to inform of completion. This patch adds calls to ide_stop_transfer, which calls ide_cmd_done, inside of ide_atapi_cmd_ok and ide_atapi_cmd_error. This fixes regressions observed by trying to boot QEMU with a Fedora 20 live CD under Q35/AHCI, which uses ATAPI command 0x00, which is a status check that may cause a hang because we never complete, and ATAPI command 0x56, which is unsupported by our current implementation and results in an error that we never report back to the guest.

2014-09-18pc: leave more space for BIOS allocationsMichael S. Tsirkin1-2/+4
Since QEMU 2.1, we are allocating more space for ACPI tables, so no space is left after initrd for the BIOS to allocate memory. Besides ACPI tables, there are a few other uses of high memory in SeaBIOS: SMBIOS tables and USB drivers use it in particular. These uses allocate a very small amount of memory. Malloc metadata also lives there. So we need _some_ extra padding there to avoid initrd breakage, but not much. John Snow found a case where RHEL5 was broken by the recent change to ACPI_TABLE_SIZE; in his case 4KB of extra padding are fine, but just to be safe I am adding 32KB, which is roughly the same amount of padding that was left by QEMU 2.0 and earlier.

2014-09-18virtio-pci: fix migration for pci bus masterMichael S. Tsirkin1-19/+20
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out VIRTIO_PCI_FLAG_BUS_MASTER_BUG and implement a simpler work-around: treat clearing of PCI_COMMAND as a virtio reset. Old guests never touch this bit so they will work. As reset clears device status, DRIVER and MASTER bits are now in sync, so we can fix up cross-version migration simply by synchronising them, without need to detect a buggy guest explicitly. Drop tracking VIRTIO_PCI_FLAG_BUS_MASTER_BUG completely. As reset makes the device quiescent, in the future we'll be able to drop checking OK bit in a bunch of places.

2014-09-12hw/arm/boot: enable DTB support when booting ELF imagesArd Biesheuvel1-2/+20
Add support for loading DTB images when booting ELF images using -kernel. If there are no conflicts with the placement of the ELF segments, the DTB image is loaded at the base of RAM.

2014-09-12hw/arm/boot: load device tree to base of DRAM if no -kernel option was passedArd Biesheuvel1-0/+10
If we are running the 'virt' machine, we may have a device tree blob but no kernel to supply it to if no -kernel option was passed. In that case, copy it to the base of RAM where it can be picked up by a bootloader.

2014-09-12hw/arm/boot: pass an address limit to and return size from load_dtb()Ard Biesheuvel1-3/+31
Add an address limit input parameter to load_dtb() so that we can tell load_dtb() how much memory the dtb is allowed to consume. If the dtb doesn't fit, return 0, otherwise return the actual size of the loaded dtb.
