2013-07-23cpu: Move gdb_regs field from CPU_COMMON to CPUStateAndreas Färber3-7/+8
Prepares for changing gdb_register_coprocessor() argument to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-07-23cpu: Introduce CPUClass::memory_rw_debug() for target_memory_rw_debug()Andreas Färber5-15/+25
Make inline target_memory_rw_debug() always available and change its argument to CPUState. Let it check if CPUClass::memory_rw_debug provides a specialized callback and fall back to cpu_memory_rw_debug() otherwise. The only overriding implementation is for 32-bit sparc.

2013-07-22bitops: Provide sextract32() and sextract64()Peter Maydell1-0/+50
A common operation in instruction decoding is to take a field from an instruction that represents a signed integer in some arbitrary number of bits, and sign extend it into a C signed integer type for manipulation. Provide new functions sextract32() and sextract64() which perform this operation; they are like the existing extract32() and extract64() except that the field is sign-extended into the returned result.

2013-07-22gtk: Fix accelerator filteringJan Kiszka1-21/+18
This is in fact very simply: When the input in grabbed, everything should be exclusively passed to the guest - except it has our magic CTRL-ALT modifier set. Then let GTK filter out those accels that are in use. When checking the modifier state, we just need to filter out NUM and CAPS lock. Note: Filtering based on hard-coded modifiers breaks overriding accelerators. Needs to be fixed at a later point.

2013-07-19virtio: Support transports which can specify the vring alignmentPeter Maydell3-3/+36
Support virtio transports which can specify the vring alignment (ie where the guest communicates this to the host) by providing a new virtio_queue_set_align() function. (The default alignment remains as before.) Transports which wish to make use of this must set the has_variable_vring_alignment field in their VirtioBusClass struct to true; they can then change the alignment via virtio_queue_set_align().

2013-07-19device_tree: Add qemu_devtree_setprop_sized_cells() utility functionsPeter Maydell2-0/+92
We already have a qemu_devtree_setprop_cells() which sets a dtb property to an array of cells whose values are specified by varargs. However for the fairly common case of setting a property to a list of addresses or of address,size pairs the number of cells used by each element in the list depends on the parent's #address-cells and #size-cells properties. To make this easier we provide an analogous qemu_devtree_setprop_sized_cells() macro which allows the number of cells used by each element to be specified. This is implemented using an underlying qemu_devtree_setprop_sized_cells_from_array() function which takes the values and sizes as an array; this may also be directly useful for cases where the cell contents are constructed programmatically.
