2014-01-13migration: Fix rate limitMatthew Garrett1-1/+1
The migration thread appears to want to allow writeout to occur at full speed rather than being rate limited during completion of state saving, but sets the limit to INT_MAX when xfer_limit is INT64_MAX. This causes problems if there's more than 2GB of state left to save at this point. It probably ought to just be INT64_MAX instead.

2014-01-12ui/cocoa: Draw black rectangle if we have no data yetPeter Maydell1-1/+6
If our redraw method is called before we have any data from the guest, then draw a black rectangle rather than leaving the window empty. This mostly only matters when the guest machine has no framebuffer device, but it is more in line with the behaviour of other QEMU UIs.

2014-01-12ui/cocoa: Redraw at correct size when switching surfacePeter Maydell1-7/+17
If the surface switch involved a resize, we were doing the redraw at the old size rather than the new, because the update of screen.width and screen.height was being done after the setFrame method calls which triggered a redraw. Normally this isn't very noticeable because typically after the guest triggers the window resize it also draws something to it, which will in turn cause us to redraw. However, the combination of a guest which never draws to the display and a command line setting of a screen size larger than the default can reveal odd effects. Move most of the handling of resizes to the top of the method, and guard it with a check that the surface size actually changed, to avoid unnecessary operations (including some user visible ones like "recenter the window on the screen") if the surface is the same size as the old one.

2014-01-12ui/cocoa: Pass command key through to guest when VM has mousegrabPeter Maydell1-7/+18
The guest might want to be able to use the command key for its won purposes (as command if it is MacOS X, or for the Windows key if it is a PC guest, for instance). In line with other UI frontends, pass it through if the guest has mousegrab, and only use it for UI menu accelerators if not grabbed.

2014-01-08target-arm: Ignore most exceptions from scalbn when doing fixpoint conversionPeter Maydell1-0/+9
The VFP fixed point conversion helpers first call float_scalbn and then convert the result to an integer. This scalbn operation may set floating point exception flags for: * overflow & inexact (if it overflows to infinity) * input denormal squashed to zero * output denormal squashed to zero Of these, we only care about the input-denormal flag, since the output of the whole scale-and-convert operation will be an integer (so squashed-output-denormal and overflow don't apply). Suppress the others by saving the pre-scalb exception flags and only copying across a potential input-denormal flag.

2014-01-08target-arm: Prepare VFP_CONV_FIX helpers for A64 usesWill Newton1-14/+14
Make the VFP_CONV_FIX helpers a little more flexible in preparation for the A64 uses. This requires two changes: * use the correct softfloat conversion function based on itype rather than always the int32 one; this is possible now that softfloat provides int16 versions and necessary for the future conversion-to-int64 A64 variants. This also allows us to drop the awkward 'sign' macro argument. * split the 'fsz' argument which currently controls both width of the input float type and width of the output integer type into two; this will allow us to specify the A64 64-bit-int-to-single conversion function, where the two widths are different. We can also drop the (itype##_t) cast now that softfloat guarantees that all the itype##_to_float* functions take an integer argument of exactly the correct type.

2014-01-08softfloat: Add support for ties-away roundingPeter Maydell2-1/+56
IEEE754-2008 specifies a new rounding mode: "roundTiesToAway: the floating-point number nearest to the infinitely precise result shall be delivered; if the two nearest floating-point numbers bracketing an unrepresentable infinitely precise result are equally near, the one with larger magnitude shall be delivered." Implement this new mode (it is needed for ARM). The general principle is that the required code is exactly like the ties-to-even code, except that we do not need to do the "in case of exact tie clear LSB to round-to-even", because the rounding operation naturally causes the exact tie to round up in magnitude.

In preparation for adding conversions between float16 and float64, factor out code currently done inline in the float16<=>float32 conversion functions into functions RoundAndPackFloat16 and NormalizeFloat16Subnormal along the lines of the existing versions for the other float types. Note that we change the handling of zExp from the inline code to match the API of the other RoundAndPackFloat functions; however we leave the positioning of the binary point between bits 22 and 23 rather than shifting it up to the high end of the word.

2014-01-08softfloat: Fix factor 2 error for scalbn on denormal inputsPeter Maydell1-8/+21
If the input to float*_scalbn() is denormal then it represents a number 0.[mantissabits] * 2^(1-exponentbias) (and the actual exponent field is all zeroes). This means that when we convert it to our unpacked encoding the unpacked exponent must be one greater than for a normal number, which represents 1.[mantissabits] * 2^(e-exponentbias) for an exponent field e. This meant we were giving answers too small by a factor of 2 for all denormal inputs. Note that the float-to-int routines also have this behaviour of not adjusting the exponent for denormals; however there it is harmless because denormals will all convert to integer zero anyway.
