2012-12-11exynos4210/mct: Avoid infinite loop on non incremental timersJean-Christophe DUBOIS1-1/+1
Check for a 0 "distance" value to avoid infinite loop when the expired FCR timer was not programed with auto-increment. With this change the behavior is coherent with the same type of code in the exynos4210_gfrc_restart() function in the same file. Linux seems to mostly use this timer with auto-increment which explain why it is not a problem most of the time. However other OS might have a problem with this if they don't use the auto-increment feature.

2012-12-11xilinx_zynq: Add one variable to avoid overwriting QSPI buswalimis1-4/+5
commit 7b482bcf xilinx_zynq: added QSPI controller Adds one QSPI controller, which has two spi buses, one is for spi0, and another is for spi1. But when initializing the spi1 bus, "dev" has been overwrited by the ssi_create_slave_no_init() function, so that qdev_get_child_bus() returns NULL and the last two m25p80 flashes won't be attached to the spi1 bus, but to main-system-bus.

2012-12-11hw/arm_gic_common: Correct GICC_PMR reset value for newer GICsPeter Maydell2-2/+8
The GIC architecture specification for v1 and v2 GICs (as found on the Cortex-A9 and newer) states that the GICC_PMR reset value is zero; this differs from the 0xf0 reset value used on 11MPCore. The NVIC is different again in not having a CPU interface; since we share the GIC code we must force the priority mask field to allow through all interrupts.

2012-12-11hw/arm_gic: Fix comparison with priority mask registerPeter Maydell1-1/+1
The GIC spec states that only interrupts with higher priority than the value in the GICC_PMR priority mask register are passed through to the processor.

2012-12-11hw/arm_boot, exynos4210, highbank: Fix secondary boot GIC initPeter Maydell3-8/+26
Fix the code in the secondary CPU boot stubs so that it correctly initialises the GIC rather than relying on bugs or implementation dependent aspects of the QEMU GIC implementation: * set the GIC_PMR.Priority field to all-ones, so that all interrupts are passed through. The default of all-zeroes means all interrupts are masked, and QEMU only booted because of a bug in the priority masking in our GIC implementation. * add a barrier after GIC setup and before WFI to ensure that GIC config is complete before we go into a possible low power state. This isn't needed with the software GIC model but could be required when using KVM and executing this code on the real hardware CPU. Note that of the three secondary stub implementations, only the common generic one needs to support both v6 and v7 DSB encodings; highbank and exynos4210 will always be v7 CPUs.

2012-12-11Support default block interfaces per QEMUMachineChristian Borntraeger14-44/+30
There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a default/standard interface to their block devices / drives. Therefore, this patch introduces a new field default_block_type per QEMUMachine struct. The prior use_scsi field becomes thereby obsolete and is replaced through .default_block_type = IF_SCSI. This patch also changes the default for s390x to IF_VIRTIO and removes an early hack that converts IF_IDE drives. Other parties have already claimed interest (e.g. IF_SD for exynos) To create a sane default, for machines that dont specify a default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1. I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c) as well as IF_IDE and it seems that it is ok to change the defines - in other words, I found no obvious (to me) assumption in the code regarding IF_NONE==0. IF_NONE is only set if there is an explicit if=none. Without if=* the interface becomes IF_DEFAULT. I would suggest to have some additional care, e.g. by letting this patch sit some days in the block tree.

2012-12-11virtio-blk: Remove duplicate property definitionDavid Gibson2-2/+0
For the virtio-blk device (via virtio-pci) the property "config-wce" is defined in two places. First, it's defined from the DEFINE_VIRTIO_BLK_FEATURES macro, second it's defined directly in virtio-pci, just two lines above the call to that macro. The direct definition in virtio-pci.c is broken, since it operates on the 'config_wce' field of VirtIOBlkConf, which is never used anywhere else. Therefore, this patch removes both the extra property definition and the redundant field it works on.

Also, move some of the qdev-core.h typedefs to the new file, too, so other headers don't need to include qdev-core.h only because of DeviceState and other typedefs.

2012-12-04usb-tablet: Allow connecting to ehciHans de Goede2-1/+93
Our ehci code has is capable of significantly lowering the wakeup rate for the hcd emulation while the device is idle. It is possible to add similar code ot the uhci emulation, but that simply is not there atm, and there is no reason why a (virtual) usb-tablet can not be a USB-2 device. Making usb-hid devices connect to the emulated ehci controller instead of the emulated uhci controller on vms which have both lowers the cpuload for a fully idle vm from 20% to 2-3% (on my laptop). An alternative implementation to using a property to select the tablet type, would be simply making it a new device type, ie usb-tablet2, but the downside of that is that this will require libvirt changes to be available through libvirt at all, and then management tools changes to become the default for new vms, where as using a property will automatically get any pc-1.3 type vms the lower cpuload.

2012-12-04ehci: Lower timer freq when the periodic schedule is idleHans de Goede2-6/+34
Lower the timer freq if no iso schedule packets complete for 64 frames in a row. We can safely do this, without adding latency, because: 1) If there is isoc traffic this will never trigger 2) For async handled interrupt packets (only usb-host), the completion handler will immediately schedule the frame_timer from a bh 3) All devices using NAK to signal no data for interrupt endpoints now use wakeup, which will immediately schedule the frame_timer from a bh The advantage of this is that when we only have interrupt packets in the periodic schedule, async_stepdown can do its work and significantly lower the frequency at which the frame_timer runs.

2012-12-04usb: Don't allow USB_RET_ASYNC for interrupt packetsHans de Goede4-0/+7
It is tempting to use USB_RET_ASYNC for interrupt packets, rather then the current NAK + polling approach, but this causes issues for migration, as an async completed packet will not getting written back to guest memory until the next poll time, and if a migration happens in between it will get lost! Make an exception for host devices, because: 1) host-linux actually uses async completion for interrupt endpoints 2) host devices don't migrate anyways Ideally we would convert host-linux.c to handle (input) interrupt endpoints in a buffered manner like it does for isoc endpoints, keeping multiple urbs submitted to ensure the devices timing requirements are met, as well as making its interrupt ep handling the same as other usb-devices.
