| | | | | | | | | | This mask contains all of the bits that should be ignored while single stepping in the debugger. The mask contains 2 bits that are not currently cleared, but are also never set.

| | | | | | | | | | These defines will be place-holders for cpu-specific functionality. Generic code will, at the end of the patch series, no longer have to concern itself about how SMI, NMI, etc should be handled. Instead, generic code will know only that the interrupt is internal or external. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* cpu-all.h: Remove unnecessary target-specific ifdef for CPU_QuadUPeter Maydell2011-04-041-3/+2
| | | | | | | | | | | CPU_QuadU isn't used on all targets, but there's no harm in defining the typedef anyway. It only needs to be guarded by CONFIG_SOFTFLOAT, because softfloat-native doesn't have a float128 type. This avoids the need for every new target which uses CPU_QuadU to add itself to an #ifdef in what ought to be target-agnostic code.

So user will get the following result: panic type: "Fatal machine check on current CPU" "broadcast" option is used for injecting dummy data into other cpus. Injecting mce with this option the expected result could be gotten.

* linux-user: fix build on hosts not using guest baseAurelien Jarno2010-07-301-0/+2
| | | | | | | | Commit 68a1c816868b3e35a1da698af412b29e61b1948a broke qemu on hosts not using guest base. It uses reserved_va unconditionally in mmap.c. To avoid to many #ifdef #endif blocks, define RESERVED_VA as either reserved_va or 0ul, and use it instead of reserved_va, similarly to what has been done with guest_base/GUEST_BASE.

* ramblocks: Make use of DeviceState pointer and BusInfo.get_dev_pathAlex Williamson2010-07-061-0/+1
| | | | | | | | | | | | | With these two pieces in place, we can start naming ramblocks. When the device is present and it lives on a bus that provides a device path, we concatenate the path and the provided name. Otherwise we just use name. The resulting id string must be unique. For now we assume an allocation for the same name and size is a device that has been removed and reinserted and return the same block. This will go away once qemu_ram_free() is implemented.

* kvm: Flush coalesced MMIO buffer periodlySheng Yang2010-02-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | The default action of coalesced MMIO is, cache the writing in buffer, until: 1. The buffer is full. 2. Or the exit to QEmu due to other reasons. But this would result in a very late writing in some condition. 1. The each time write to MMIO content is small. 2. The writing interval is big. 3. No need for input or accessing other devices frequently. This issue was observed in a experimental embbed system. The test image simply print "test" every 1 seconds. The output in QEmu meets expectation, but the output in KVM is delayed for seconds. Per Avi's suggestion, I hooked flushing coalesced MMIO buffer in VGA update handler. By this way, We don't need vcpu explicit exit to QEmu to handle this issue. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
