2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-07-11pci: don't overwrite multi functio bit in pci header type.Isaku Yamahata
Don't overwrite pci header type. Otherwise, multi function bit which pci_init_header_type() sets appropriately is lost. Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero which is already zero cleared. how to test: run qemu and issue info pci to see whether a device in question is normal device, not pci-to-pci bridge.

2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno
A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.

2009-10-12rom loader: fix sparc -kernel boot.Gerd Hoffmann
Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.

2009-10-07New qdev_init_nofail()Markus Armbruster
Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.
