2011-01-22microblaze: Improve subkcEdgar E. Iglesias
Move code from the helper into the translator. The remaining helper parts can reuse helper_addkc, making it possible to remove helper_subkc entirely. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>

2011-01-22microblaze: Improve addkcEdgar E. Iglesias
* Optimize handling when carry is not updated. * Optimize handling for adds with nop semantics. * Move code from helper_addkc to the translator making helper_addkc PURE and CONST. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>

2011-01-21sm501: fix screen redrawAurelien Jarno
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>
2011-01-20checkpatch: adjust to QEMUismsBlue Swirl

2011-01-20gt64xxx: set isa_mem_base during registrationAurelien Jarno
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 Maydell
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 Jarno
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 Jarno
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 Yamahata
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>

2011-01-20usb-hid: modifiers should generate an eventAurelien Jarno
When a modifier key is pressed or released, the USB HID keyboard still answers NAK, unless another key is also pressed or released. The patch fixes that by calling usb_hid_changed() when a modifier key is pressed or released. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20softfloat: fix floatx80_is_{quiet,signaling}_nan()Aurelien Jarno
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. This patch fixes that by applying the same kind of comparison as for other float formats, but taking into account the explicit bit. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-19pci: fix device pathsMichael S. Tsirkin
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. Fix it up by snprintf to a buffer which is larger by 1 byte and then memcpy the data (without the null byte) to where we need it. Reported-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Michael S.

2011-01-18mips: Expire late timers when reading cp0_countEdgar E. Iglesias
When reading cp0_count from a timer with a late trigger that should already have expired, expire it and raise the timer irq. This makes it possible for guest code (e.g, Linux) that first read cp0_count, then compare it with cp0_compare and check for raised timer interrupt lines to run reliably.
