2010-05-15fdc: Register vmstate via qdevJan Kiszka1-5/+30

2010-05-15serial: Register vmstate via qdevJan Kiszka1-1/+12
At least for isa-serial, we can already let qdev do the vmstate registration for us. It just takes wrapping vmstate for the encapsulating ISASerialState and defining the proper instance ID aliases. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-05-15vmstate: Add support for alias IDJan Kiszka4-5/+39
Some legacy users (mostly PC devices) of vmstate_register manage instance IDs on their own, and that unfortunately in a way that is incompatible with automatically generated ones. This so far prevents switching those users to vmstates that are registered by qdev. To establish a migration path, this patch introduces the concept of alias IDs. They can be passed to an extended vmstate registration service, and qdev provides a set service to be used during device init. find_se will consider the alias in addition to the default ID. We can then start generating the default ID automatically and writing it on vmsave, thus converting that format without breaking support for upward migration. The user is required specify the highest vmstate version for which the alias is required. Once this version falls behind the minimum required for a specific vmstate, an assertion triggers to motivate cleaning up the obsolete alias.

2010-05-15sh: sm501: add 2D engine supportShin-ichiro KAWASAKI1-3/+169
In linux kernel v2.6.33, sm501 frame buffer driver modified to support 2D graphics engine on sm501 chip. One example is "fill rectangle" operation. But current qemu's sm501 emulation doesn't support it. This results in graphics console disturbance. This patch introduces sm501 2D graphics engine emulation and solve this problem. Add SM501 2D hardware engine support. - Add 2D engine register set read/write handlers. - Support 'fill rectangle'. Other operations are left for future work. - Update SM501 support status comment.
