2011-01-23gdbstub-xml: avoid a warning from sparseBlue Swirl1-0/+3
Include a header to get the declaration for xml_builtin. This avoids a warning from sparse: CC m68k-softmmu/gdbstub-xml.o gdbstub-xml.c:244:12: warning: symbol 'xml_builtin' was not declared. Should it be static? Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-01-23Avoid deadlock whith iothread and icountEdgar E. Iglesias1-6/+9
When using the iothread together with icount, make sure the qemu_icount counter makes forward progress when the vcpu is idle to avoid deadlocks. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>

2011-01-22microblaze: Improve subkcEdgar E. Iglesias3-38/+49

2011-01-21sm501: fix screen redrawAurelien Jarno1-3/+4
Due to signed/unsigned comparison, the dirty bits are never reset, and the screen redrawn each time. Fix that by only using ram_addr_t types, and looking for page_min != addr_max instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-20gt64xxx: set isa_mem_base during registrationAurelien Jarno1-0/+5
isa_mem_base is computed from registers during reset, but due to QEMU limitations some devices (e.g. VGA card) need to know it earlier when they are registered. Workaround this by setting the value during registration instead of reset. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20hw/pl190.c: Fix writing of default vector addressPeter Maydell1-3/+1
The PL190 implementation keeps the default vector address in vect_addr[16], but we weren't using this for writes to the DEFVECTADDR register. As a result of this fix the default_addr structure member is unused and we can delete it.

2011-01-20target-ppc: fix wrong NaN testsAurelien Jarno1-17/+28
Some tests in FPU emulation code were wrongly using float64_is_nan() before commit 185698715dfb18c82ad2a5dbc169908602d43e81, and wrongly using float64_is_quiet_nan() after. Fix them by using float64_is_any_nan() instead. Reviewed-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20target-ppc: fix sNaN propagationAurelien Jarno1-69/+78
The current FPU code returns 0.0 if one of the operand is a signaling NaN and the VXSNAN exception is disabled. fload_invalid_op_excp() doesn't return a qNaN in case of a VXSNAN exception as the operand should be propagated instead of a new qNaN to be generated. Fix that by calling fload_invalid_op_excp() only for the exception generation (if enabled), and use the softfloat code to correctly compute the result.

2011-01-20pci: deassert intx on reset.Isaku Yamahata2-0/+11
deassert intx on device reset. So far pci_device_reset() is used for system reset. In that case, interrupt controller is reset at the same time so that all irq is are deasserted. But now pci bus reset/flr is supported, and in that case irq needs to be disabled explicitly. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-01-20softfloat: fix floatx80_is_{quiet,signaling}_nan()Aurelien Jarno1-4/+8
floatx80_is_{quiet,signaling}_nan() functions are incorrectly detecting the type of NaN, depending on SNAN_BIT_IS_ONE, one of the two is returning the correct value, and the other true for any kind of NaN.

Patch a6a7005d14b3c32d4864a718fb1cb19c789f58a5 generated broken device paths. We snprintf with a length shorter than the output, so the last character is discarded and replaced by the null byte.
