2011-11-09configure: fix detection for xattr.h on modern distributionsAvi Kivity4-4/+4
Modern distributions place xattr.h in /usr/include/sys, and fold libattr.so into libc. They also don't have an ENOATTR. Make configure detect this, and add a qemu-xattr.h file that directs the #include to the right place. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-11-07qxl: fix vga port initialization.Gerd Hoffmann1-5/+17
Commit 0a039dc70096b768d3810afa50ba1d214768aaf4 broke vga modes for qxl-vga by loosing vga_ioport_read windup. qxl needs to hook into vga port writes only and used to realize that by letting vga_init() do the work for both reads and writes, then overwrite the write function. That little detail was missed while doing the conversion ... This patch fixes it. It also switch qxl vga ioport registration to portio lists while being at it.

2011-11-06arm_gic: handle banked enable bits for per-cpu interruptsRabin Vincent1-15/+20
The first enable set/clear register (which controls the PPIs and SGIs) is supposed to be banked for each processor. Currently it is just handled globally and this prevents recent SMP Linux kernels from booting, because CPU0 stops receiving localtimer interrupts when CPU1 disables them locally. To fix this, allow the enable bits to be enabled per-cpu. For SPIs, always enable/disable ALL_CPU_MASK.

2011-11-04dma: Avoid reentrancy in DMA transfer handlersKevin Wolf1-0/+10
With the conversion of the block layer to coroutines, bdrv_read/write have changed to run a nested event loop that calls qemu_bh_poll. Consequently a scheduled BH can be called while a DMA transfer handler runs and this means that DMA_run becomes reentrant. Devices haven't been designed to cope with that, so instead of running a nested transfer handler just wait for the next invocation of the BH from the main loop. This fixes some problems with the floppy device. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-11-02Fix X86 CPU topology in KVM modeBharata B Rao1-1/+0
apic id returned to guest kernel in ebx for cpuid(function=1) depends on CPUX86State->cpuid_apic_id which gets populated after the cpuid information is cached in the host kernel. This results in broken CPU topology in guest. Fix this by setting cpuid_apic_id before cpuid information is passed to the host kernel. This is done by moving the setting of cpuid_apic_id to cpu_x86_init() where it will work for both KVM as well as TCG modes.

2011-11-02virtio-blk: pass full status to the guestPaolo Bonzini1-1/+15
When SCSI passthrough is being used by the guest with virtio-blk, the guest is not able to detect disk failures. This is because the status field is expected by the guest driver to include also the msg_status, host_status and driver_status fields, but the device is only passing down the SCSI status. The patch fixes this, and also makes sure that the guest always sees a CHECK_CONDITION status when there is valid sense data. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-11-01virtio: Add PCI memory BAR in addition to PIO BARDavid Gibson1-0/+2
Currently, virtio devices are usually presented to the guest as an emulated PCI device, virtio_pci. Although the actual IO operations are done through system memory, the configuration of the virtio device is done through the one PCI IO space BAR that virtio_pci presents. But PCI IO space (aka PIO) is deprecated for modern PCI devices, and on some systems with many PCI domains accessing PIO space can be problematic. For example on the existing PowerVM implementation of the PAPR spec, PCI PIO access is not supported at all. We're hoping that our KVM implementation will support PCI PIO (once we support PCI at all), but it will probably have some irritating limitations. This patch, therefore, extends the virtio_pci device to have a PCI memory space (MMIO) BAR as well as the IO BAR. The MMIO BAR contains exactly the same registers, in exactly the same layout as the existing PIO BAR. Because the PIO BAR is still present, existing guest drivers should still work fine. With this change in place, future guest drivers can check for an MMIO BAR and use that if present (falling back to PIO when possible to support older qemu versions).

2011-11-01Add stub functions for PCI device models to do PCI DMADavid Gibson1-0/+67
This patch adds functions to pci.[ch] to perform PCI DMA operations. At present, these are just stubs which perform directly cpu physical memory accesses. Stubs are included which are analogous to cpu_physical_memory_{read,write}(), the stX_phys() and ldX_phys() functions and cpu_physical_memory_{map,unmap}(). In addition, a wrapper around qemu_sglist_init() is provided, which also takes a PCIDevice *. It's assumed that _init() is the only sglist function which will need wrapping, the idea being that once we have IOMMU support whatever IOMMU context handle the wrapper derives from the PCI device will be stored within the sglist structure for later use. Using these stubs, however, distinguishes PCI device DMA transactions from other accesses to physical memory, which will allow PCI IOMMU support to be added in one place, rather than updating every PCI driver at that time. That is, it allows us to update individual PCI drivers to support an IOMMU without having yet determined the details of how the IOMMU emulation will operate. This will let us remove the most bitrot-sensitive part of an IOMMU patch in advance.

2011-11-01qxl: create slots on post_load in vga stateAlon Levy1-7/+19
RHBZ 740547 If we migrate when the device is in vga state the guest still believes the slots are created, and will cause operations that reference the slots, causing a "panic: virtual address out of range" on the first of them. Easy to see by migrating in vga mode with a driver loaded, for instance windows cmd window in full screen mode, and then exiting vga mode back to native mode will cause said panic. Fixed by doing the slot recreation in post_load for vga mode as well. Note that compat does not require any changes because it creates it's only slot by a side effect of QXL_IO_SET_MODE.
