ROM files that are put in FW CFG are copied to guest ram, by BIOS, but they are not backed by RAM so they don't get migrated. Each time we change two bytes in such a ROM this breaks cross-version migration: since we can migrate after BIOS has read the first byte but before it has read the second one, getting an inconsistent state. Future-proof this by creating, for each such ROM, an MR serving as the backing store. This MR is never mapped into guest memory, but it's registered as RAM so it's migrated with the guest. Naturally, this only helps for -M 1.7 and up, older machine types will still have the cross-version migration bug. Luckily the race window for the problem to trigger is very small, which is also likely why we didn't notice the cross-version migration bug in testing yet. Signed-off-by: NMichael S.

This patch is based on Hu Tao's: http://lists.nongnu.org/archive/html/qemu-devel/2013-08/msg00124.html No need to hard-code pvpanic as part of the machine. It can be added with "-device pvpanic" from command line (The next patch). Anyway, for backport compatibility it is still part of 1.5 machine.

The BIOS that we ship in 1.6 does not use pci info from host (yet). Several issues turned up (e.g. around winXP boot crashes).

pci_find_root_bus() takes a domain parameter. Currently PCI root buses with domain other than 0 can't be created, so this is more or less a long winded way of retrieving the main PCI root bus. Numbered domains don't actually properly cover the (non x86) possibilities for multiple PCI root buses, so this patch for now enforces the domain == 0 restriction in other places to replace pci_find_root_bus() with an explicit pci_find_primary_bus().

This causes at least one known problems: Windows XP disables sysenter when (family == 6 && model <= 2), but Skype tries to use the sysenter instruction anyway because it is reported as available on CPUID, making it crash.

The isapc machine with seabios currently requires the BIOS region to be read/write memory rather than read-only memory. KVM currently cannot support the BIOS as a ROM region, but qemu in non-KVM mode can. Based on this, isapc machine currently only works with KVM. To work-around this isapc issue, this change avoids marking the BIOS as readonly for isapc. This change also will allow KVM to start supporting ROM mode via KVM_CAP_READONLY_MEM.

由 Markus Armbruster 提交于
Use of a flash memory device for the BIOS was added in series "[PATCH v10 0/8] PC system flash support", commit 4732dcaf..1b89fafe, v1.1. Flash vs. ROM is a guest-visible difference. Thus, flash use had to be suppressed for machine types pc-1.0 and older. This was accomplished by adding a dummy device "pc-sysfw" with property "rom_only": * Non-zero rom_only means "use ROM". Default for pc-1.0 and older. * Zero rom_only means "maybe use flash". Default for newer machines. Not only is the dummy device ugly, it was also retroactively added to the older machine types! Fortunately, it's not guest-visible (thus no immediate guest ABI breakage), and has no vmstate (thus no immediate migration breakage). Breakage occurs only if the user unwisely enables flash by setting rom_only to zero. Patch review FAIL #1. Why "maybe use flash"? Flash didn't (and still doesn't) work with KVM. Therefore, rom_only=0 really means "use flash, except when KVM is enabled, use ROM". This is a Bad Idea, because it makes enabling/ disabling KVM guest-visible. Patch review FAIL #2. Aside: it also precludes migrating between KVM on and off, but that's not possible for other reasons anyway. Fix as follows: 1. Change the meaning of rom_only=0 to mean "use flash, no ifs, buts, or maybes" for pc-i440fx-1.5 and pc-q35-1.5. Don't change anything for older machines (to remain bug-compatible). 2. Change the default value from 0 to 1 for these machines. Necessary, because 0 doesn't work with KVM. Once it does, we can flip the default back to 0. 3. Don't revert the retroactive addition of device "pc-sysfw" to older machine types. Seems not worth the trouble. 4. Add a TODO comment asking for device "pc-sysfw" to be dropped once flash works with KVM. Net effect is that you get a BIOS ROM again even when KVM is disabled, just like for machines predating the introduction of flash. To get flash instead, use "--global pc-sysfw.rom_only=0".
