The sequence of reading from eeprom is "offset by one" moved because of a false detection of a clock cycle after an eeprom reset. Keeping the last clock value after a reset keeps it in sync. Signed-off-by: Naphtali Sprei <nsprei@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This patch is a major overhaul of the device properties. The properties are saved directly in the device state struct now, the linked list of property values is gone. Advantages: * We don't have to maintain the list with the property values. * The value in the property list and the value actually used by the device can't go out of sync any more (used to happen for the pci.devfn == -1 case) because there is only one place where the value is stored. * A record describing the property is required now, you can't set random properties any more. There are bus-specific and device-specific properties. The former should be used for properties common to all bus drivers. Typical use case is bus addressing, i.e. pci.devfn and i2c.address. Properties have a PropertyInfo struct attached with name, size and function pointers to parse and print properties. A few common property types have PropertyInfos defined in qdev-properties.c. Drivers are free to implement their own very special property parsers if needed. Properties can have default values. If unset they are zero-filled.

Hi, Whoever wrote this migrate_set_speed function is totally stupid. Any failed or completed migration keeps its state to allow probing of migration data, but has no associated file anymore. It is, thus, possible to crash qemu by calling migrate_set_speed after a migration is finished (or failed, or cancelled), but before another one starts. This patch fixes it.

This patch removes dead i386 assembly code from softmmu_header.h. The code is conditional on ASM_SOFTMMU, which is never defined. Optimisation for the fast path is already handled by tcg_out_qemu_ld() and tcg_out_qemu_st(), so there seems to be little need for this code.

Instead of doing our own check for protocols which fails because raw isn't formally a protocol but special cased in find_protocol specify the BDRV_O_FILE option to use the same code as bdrv_file_open does.

Using int for cpu_{in, out}[bwl] is inconsistent with other part because for address or value, uintN_t is used by other qemu part. At least, softmmu, CPU{Read, Write}MemoryFunc, pci, target_phys_addr_t and the callers of cpu_{in, out}[bwl](). This patch removes the inconsistency. IO port has its own address space so define pio_addr_t as uint32_t because PCI io space width is 32bit. And use uint{32, 16, 8}_t for ioport value. Changing signedness of value might cause subtle issue. However only a suspicious caller is kvm_handle_io() which is ok. And other callers pass unsigned value in the first place.

Since we recently do not disable 3DNOW! support anymore, we should avoid setting the bits in the default qemu64 CPU model to ease migration. TCG does not support it anyway and even AMD deprecates it's usage nowadays. If you want to use it in KVM, use the phenom, athlon or host CPU model.

-S is not honored by qemu on incoming migration. If a domain is migrated while paused, thus, it will start running on the remote machine; this is wrong. Given the trivial patch to fix this, it looks more like a thinko than anything else, probably dating back to the qemu-kvm merge. The interesting part is that the -S mechanism was in fact *used* when migrating (setting autostart = 0) and the incoming migration code was starting the VM at the end of the migration. Since I was removing the vm_start from there, I also corrected a related imprecision. The code was doing a vm_stop "just in case", but we can be sure that the VM is not running---the vm_start call in vl.c has not been reached yet. So the vm_stop is removed together with the vm_start.
