2016-10-06rules.mak: quiet-command: Split command name and args to printPeter Maydell12-100/+106
The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

2016-10-04target-arm: Correctly handle 'sub pc, pc, 1' for ARMv6Peter Maydell1-1/+6
In the ARM v6 architecture, 'sub pc, pc, 1' is not an interworking branch, so the computed new value is written to r15 as a normal value. The architecture says that in this case, bits [1:0] of the value written must be ignored if we are in ARM mode (or bit [0] ignored if in Thumb mode); this is a change from the ARMv4/v5 specification that behaviour is UNPREDICTABLE. Use the correct mask on the PC value when doing a non-interworking store to PC. A popular library used on RaspberryPi uses this instruction as part of a trick to determine whether it is running on ARMv6 or ARMv7, and we were mishandling the sequence.

2016-10-04generic-loader: Add a generic loaderAlistair Francis4-0/+265
Add a generic loader to QEMU which can be used to load images or set memory values. Internally inside QEMU this is a device. It is a strange device that provides no hardware interface but allows QEMU to monkey patch memory specified when it is created. To be able to do this it has a reset callback that does the memory operations. This device allows the user to monkey patch memory. To be able to do this it needs a backend to manage the datas, the same as other memory-related devices. In this case as the backend is so trivial we have merged it with the frontend instead of creating and maintaining a seperate backend.

2016-10-04hw/intc/arm_gicv3_its: Implement support for in-kernel ITS emulationPavel Fedin2-0/+122
The ITS control frame is in-kernel emulated while accesses to the GITS_TRANSLATER are mediated through the KVM_SIGNAL_MSI ioctl (MSI direct MSI injection advertised by the CAP_SIGNAL_MSI capability) the kvm_gsi_direct_mapping is explicitly set to false to emphasize the difference with GICv2M. Direct mapping cannot work with ITS since the content of the MSI data is not the target interrupt ID but an eventd id. GSI routing is advertised (kvm_gsi_routing_allowed) as well as msi/irqfd signaling (kvm_msi_via_irqfd_allowed). The MSI frame (GITS_TRANSLATER) absolute GPA is computed on first kvm_its_send_msi() call. It is then passed through KVM_SIGNAL_MSI ioctl.

Advertise gsi routing and set up irqchip routing entries for GIC SPIs. This is not mandated as long as MSI routing is not used (because the kernel sets a default irqchip routing table). However once MSI routing gets used (for VIRTIO-PCI vhost for example), the first call to KVM_SET_GSI_ROUTING overrides the kernel default irqchip table. If no routing entry exists for the GSI, any IRQFD signaling for this GSI will fail.

2016-10-03target-i386: Correct family/model/stepping for Opteron_G3Evgeny Yakovlev2-3/+18
Current CPU definition for AMD Opteron third generation includes features like SSE4a and LAHF_LM support in emulated CPUID. These features are present in K8 rev.E or K10 CPUs and later. However, current G3 family and model describe 2nd generation K8 cores instead. This is incorrect but was considered harmless until our tests found a problem with linux kernels >= 3.10 (and maybe earlier) which specifically check for Opteron K8 model when parsing CPUID leaf 0x80000001: http://lxr.free-electrons.com/source/arch/x86/kernel/cpu/amd.c?v=3.16#L552 This code will disable LAHF_LM feature in /proc/cpuinfo if model number is inconsistent. This change sets Opteron_G3 family/model/stepping to 16/2/3 which is a proper Opteron 3rd generation 2350 CPU. Signed-off-by: Evgeny Yakovlev <eyakovlev@virtuozzo.com> Signed-off-by: Denis V.

2016-10-03target-i386: Report known CPUID[EAX=0xD,ECX=0]:EAX bits as migratableEduardo Habkost1-8/+11
A regression was introduced by commit 96193c22a "target-i386: Move xsave component mask to features array": all CPUID[EAX=0xD,ECX=0]:EAX bits were being reported as unmigratable because they don't have feature names defined. This broke "-cpu host" because it enables only migratable features by default. This adds a new field to FeatureWordInfo: migratable_flags, which will make those features be reported as migratable even if they don't have a property name defined.

Similar to existing fixes for IDE (87ac25fd) and ATAPI (7f951b2d), the AIOCB must be cleared in the callback. Otherwise, we may accidentally try to reset a dangling pointer in bdrv_aio_cancel() from a port reset.

2016-09-29ide: fix DMA register transitionsJohn Snow1-1/+1
ATA8-APT defines the state transitions for both a host controller and for the hardware device during the lifecycle of a DMA transfer, in section 9.7 "DMA command protocol." One of the interesting tidbits here is that when a device transitions from DDMA0 ("Prepare state") to DDMA1 ("Data_Transfer State"), it can choose to set either BSY or DRQ to signal this transition, but not both. as ide_sector_dma_start is the last point in our preparation process before we begin the real data transfer process (for either AHCI or BMDMA), this is the correct transition point for DDMA0 to DDMA1. I have chosen !BSY && DRQ for QEMU to make the transition from DDMA0 the most obvious.
