PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> |
