2015-09-07arm: Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2015-07-07macio: remove nonexistent interrupt on pin 1Cormac O'Brien
The current macio implementation declares an interrupt that doesn't appear to exist in the hardware or any other emulator implementation. OpenBIOS detects this interrupt and generates an 'interrupts' property in the macio device tree entry. Mac OS 9 halts boot when it detects this interrupt, so it has been removed to permit further progress in the boot process.

2015-06-19pci: Don't register a specialized 'config_write' if default behavior is intendedShmulik Ladkani
Few devices have their specialized 'config_write' methods which simply call 'pci_default_write_config' followed by a 'msix_write_config' or 'msi_write_config' calls, using exact same arguments. This is unnecessary as 'pci_default_write_config' already invokes 'msi_write_config' and 'msix_write_config'. Also, since 'pci_default_write_config' is the default 'config_write' handler, we can simply avoid the registration of these specialized versions.

2014-09-08PPC: Cuda: Use cuda timer to expose tbfreq to guestAlexander Graf
Mac OS X calibrates a number of frequencies on bootup based on reading tb values on bootup and comparing them to via cuda timer values. The only variable we can really steer well (thanks to KVM) is the cuda frequency. So let's use that one to fake Mac OS X into believing the bus frequency is tbfreq * 4. That way Mac OS X will automatically calculate the correct timebase frequency. With this patch and the patch set I posted earlier I can successfully run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

2014-08-18memory: convert memory_region_destroy to object_unparentPaolo Bonzini
Explicitly call object_unparent in the few places where we will re-create the memory region. If the memory region is simply being destroyed as part of device teardown, let QOM handle it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-08-05vfio: Don't cache MSIMessageAlex Williamson
Commit 40509f7f added a test to avoid updating KVM MSI routes when the MSIMessage is unchanged and f4d45d47 switched to relying on this rather than doing our own comparison. Our cached msg is effectively unused now. Remove it. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2014-08-05vfio: Fix MSI-X vector expansionAlex Williamson
When new MSI-X vectors are enabled we need to disable MSI-X and re-enable it with the correct number of vectors. That means we need to reprogram the eventfd triggers for each vector. Prior to f4d45d47 vector->use tracked whether a vector was masked or unmasked and we could always pick the KVM path when available for unmasked vectors. Now vfio doesn't track mask state itself and vector->use and virq remains configured even for masked vectors. Therefore we need to ask the MSI-X code whether a vector is masked in order to select the correct signaling path. As noted in the comment, MSI relies on hardware to handle masking.

2014-07-22hw/misc/imx_ccm.c: Add missing VMState list terminatorPeter Maydell
The VMStateDescription for the imx_ccm device was missing its terminator. Found by static search of the codebase using a regex based on one suggested by Ian Jackson: pcregrep -rMi '(?s)VMStateField(?:(?!END_OF_LIST).)*?;' $(git grep -l 'VMStateField\[\]') Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Cc: qemu-stable@nongnu.org
