The u16 and u32 types don't exist in QEMU common headers. It never broke build because these two macros aren't use by the current code, but this is about to change with the future addition of functional tests for 9P.

Split the existing init_iov_from_pdu function in two: init_out_iov_from_pdu (for writes) and init_in_iov_from_pdu (for reads). init_in_iov_from_pdu takes an additional size parameter to specify the memory required for the response message.

2016-12-27hw/intc/arm_gicv3: Don't signal Pending+Active interrupts to CPUPeter Maydell
The GICv3 requires that we only signal Pending interrupts to the CPU. This category does not include Pending+Active interrupts, which means we need to check whether the interrupt is Active in the gicr_int_pending() and gicd_int_pending() functions. Interrupts are rarely in the Active+Pending state, but KVM uses this as part of its handling of the virtual timer, so this bug was causing KVM to go into an infinite loop of taking the vtimer interrupt when the guest first triggered it.

2016-12-27hw/intc/arm_gicv3: Remove incorrect usage of fieldoffsetPeter Maydell
In the ARMCPRegInfo definitions for the GICv3 CPU interface registers, we were trying to use .fieldoffset to specify the locations of data fields within the GICv3CPUState struct. This is completely broken, because .fieldoffset is for offsets into the CPUARMState struct. We didn't notice because we were only using this for reads to BPR0, AP0R<n>, IGRPEN0 and CTLR_EL3, and Linux doesn't use these registers. Replace the .fieldoffset uses with explicit read functions.

2016-12-22hw/block/pflash_cfi*.c: fix confusing assert fail messageZiyue Yang
The patch is to fix the confusing assert fail message caused by un-initialized device structure (from bite sized tasks). The bug can be reproduced by ./qemu-system-x86_64 -nographic -device cfi.pflash01 The CFI hardware is dynamically loaded by QOM realizing mechanism, however the realizing function in pflash_cfi01_realize function requires the device being initialized manually before calling, like ./qemu-system-x86_64 -nographic -device cfi.pflash01,num-blocks=1024,sector-length=4096,name=testcard Once the initializing parameters are left off in the command, it will leave the device structure not initialized, which makes pflash_cfi01_realize try to realize a zero-volume card, causing /mnt/EXT_volume/projects/qemu/qemu-dev/exec.c:1378: find_ram_offset: Assertion `size != 0\' failed. Through my test, at least the flash device's block-number, sector-length and its name is needed for pflash_cfi01_realize to behave correctly. So I think the new asserts are needed to hint the QEMU user to specify the device's parameters correctly.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-12-20virtio-gpu: track and limit host memory allocationsGerd Hoffmann
This patch makes virtio-gpu track host memory allocations for ressources and applies a limit (configurable 256M by default). When exceeding the limit virtio-gpu throws VIRTIO_GPU_RESP_ERR_OUT_OF_MEMORY errors (like it already does today when pixman image allocations fail). This patch covers 2d mode only. For 3d mode we have to figure how we are going to handle this best. qemu doesn't track resources in case virglrenderer is used, so I guess we should extend virglrenderer to allow setting a limit, then let qemu set the limit and catch virgl_renderer_resource_create failures.

2016-12-20display: virtio-gpu-3d: check virgl capabilities max_sizePrasad J Pandit
Virtio GPU device while processing 'VIRTIO_GPU_CMD_GET_CAPSET' command, retrieves the maximum capabilities size to fill in the response object. It continues to fill in capabilities even if retrieved 'max_size' is zero(0), thus resulting in OOB access. Add check to avoid it.
