From 07323531c196223293bf266bd4d3811bd24c6e34 Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Tue, 14 Jul 2009 19:10:43 +0900 Subject: ioport: use uint{32, 16, 8}_t for ioport value and pio_addr_t for ioport address. 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.
