2012-01-12Fix qapi code generation fixAvi Kivity
The fixes to qapi code generation had multiple bugs: - the Null class used to drop output was missing some methods - in some scripts it was never instantiated, leading to a None return, which is missing even more methods - the --source and --header options were swapped Luckily, all those bugs were hidden by a makefile bug which caused the old behaviour (with the race) to be invoked.

2012-01-11target-i386: fix SSE rounding and flush to zeroAurelien Jarno
SSE rounding and flush to zero control has never been implemented. However given that softfloat-native was using a single state for FPU and SSE and given that glibc is setting both FPU and SSE state in fesetround(), this was working correctly up to the switch to softfloat. Fix that by adding an update_sse_status() function similar to update_fpu_status(), and callin git on write to mxcsr. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-01-11target-i386: fix dpps and dppd SSE2 instructionsAurelien Jarno
The helpers implemented dpps and dppd SSE instructions are not passing the correct argument types to the softfloat functions. While they do work anyway providing a correct behaviour, this patch fixes that. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-01-11target-i386: fix round{pd,ps,sd,ss} SSE2 instructionsAurelien Jarno
roundps and roundss SSE2 instructions have been broken when switching target-i386 to softfloat. They use float64_round_to_int to convert a float32, and while the implicit conversion from float32 to float64 was correct for softfloat-native, it is not for pure softfloat. Fix that by using the correct registers and correct functions. Also fix roundpd and roundsd implementation at the same time, even if these functions are behaving correctly. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-01-11target-i386: fix {min,max}{pd,ps,sd,ss} SSE2 instructionsAurelien Jarno
minpd, minps, minsd, minss and maxpd, maxps, maxsd, maxss SSE2 instructions have been broken when switching target-i386 to softfloat. It's not possible to use comparison instructions on float types anymore to softfloat, so use the floatXX_lt function instead, as the float_XX_min and float_XX_max functions can't be used due to the Intel specific behaviour. As it implements the correct NaNs behaviour, let's remove the corresponding entry from the TODO. It fixes GDM screen display on Debian Lenny. Thanks to Peter Maydell and Jason Wessel for their analysis of the problem. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2012-01-10elf: Improve symbol lookup (optimize, fix for bsd-user)Stefan Weil
Coverity complained about local variable key which was only partially initiated. Only key.st_value was set. As this was also the only part of key which was used in function symfind, the code could be optimized by directly passing a pointer to orig_addr. In bsd-user/elfload.c, fix ec822001a2f26eef8701194714f6482b6d852de2 was missing. This was a simple replacement of > by >= in symfind, so I fixed it here without creating an additional patch.

2012-01-10target-sh4: ignore ocbp and ocbwb instructionsAurelien Jarno
ocbp and ocbwb controls the writeback of a cache line to memory. They are supposed to do nothing in case of a cache miss. Given QEMU only partially emulate caches, it is safe to ignore these instructions. This fixes a kernel oops when trying to access an rtl8139 NIC with recent versions.

2012-01-10tcg/arm: Use r6 as TCG_AREG0 to avoid clash with Thumb framepointerPeter Maydell
On ARM, in Thumb mode r7 is used for the framepointer; this meant that we would fail to compile in debug mode because we were using r7 for TCG_AREG0. Shift to r6 instead to avoid this clash.

2012-01-10cris-dis: Clean memory allocationStefan Weil
The old code used sizeof(const struct cris_opcode **) where it should have used sizeof(const struct cris_opcode *). As both sizes give the same value, the resulting binary was ok, but static code analyzers like coverity and clang complained. This is fixed here, and the code is also simplified by using g_new0.

2012-01-07sm501: Fix size of color_regStefan Weil
color_reg is expected to hold 32 bit values, so it was too small.

2012-01-07malta: Fix regression (i8259 interrupts did not work)Stefan Weil
Commit 5632ae46d5bda798e971dae48ebb318ac2c3686a passes the address of i8259 to qemu_irq_proxy. i8259 is an auto variable with undefined value outside of mips_malta_init. This made the interrupt proxy unusable: either QEMU crashes, or the interrupt handler was not called. Ethernet for example no longer worked with MIPS Malta. v2: While v1 used a static variable for i8259, this patch introduces a qdev for the malta machine. i8259 is now part of the device status. This is a minimal qdev implementation to keep the patch small. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2012-01-06configure: Fix test for supported host CPU typePeter Maydell
The test for whether the host CPU is supported had several problems: * the attempt to fall back to TCI was done as a duplicate test, very late (so "--cpu foo" would fail early but "--cpu unicore32" would fail late, differently, and after configure had already printed a lot of output) * a number of CPUs only supported as guests were included in the list of CPUs we would accept as valid hosts, which would result in a late compile failure on those systems rather than a configure failure or fallback to TCI * bailing out for an unsupported CPU happened before the main option parsing, so "configure --help" wouldn't work Fix these by folding the setting of ARCH into the first test for supported host CPU, removing spurious guest-only CPU names from it, and moving the "fall back to TCI" code earlier.

Replace error_report("DEVICE-NAME: MESSAGE"); by just error_report("MESSAGE"); in block device init functions. DEVICE-NAME is bogus in some cases: it's "scsi-disk" for device scsi-hd and scsi-cd, "virtio-blk-pci" for virtio-blk-s390, and "usb-msd" for usb-storage. There is no real need to put a device name in the message, because error_report() points to the offending command line option already: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb -device virtio-blk-pci upstream-qemu: -device virtio-blk-pci: virtio-blk-pci: drive property not set upstream-qemu: -device virtio-blk-pci: Device 'virtio-blk-pci' could not be initialized And for a monitor command, it's obvious anyway: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb (qemu) device_add virtio-blk-pci virtio-blk-pci: drive property not set Device 'virtio-blk-pci' could not be initialized Reported-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
