2011-11-09hpet: fix infinite loop in qemu_run_timers with -icount enabledMax Filippov
hpet_timer timer callback rearms itself based on difference between current HPET tick counter and comparator value. Difference calculated by the hpet_calculate_diff function is limited to non-negative values. cur_tick is calculated via hpet_get_ticks that uses qemu_get_clock_ns(vm_clock). With -icount enabled vm_clock doesn't advance during qemu_run_timers loop thus once difference is zero, qemu_run_timers loops forever handling hpet_timer. Limit hpet_calculate_diff results to positive only values to avoid that infinite loop. This fixes the following qemu-system-x86_64 hang when it reaches timer_irq_works() in the linux bootup: [ 0.000000] Fast TSC calibration using PIT [ 0.000000] Detected 1000.054 MHz processor.

2011-11-07qxl: fix vga port initialization.Gerd Hoffmann
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 Vincent
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 Wolf
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 Rao
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 Bonzini
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 Gibson
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).
