2010-04-23Fix harmless if statement with empty body, spotted by clangBlue Swirl1-1/+2
This clang error is harmless but worth fixing: CC libhw32/rc4030.o /src/qemu/hw/rc4030.c:244:66: error: if statement has empty body [-Wempty-body] DPRINTF("read 0x%02x at " TARGET_FMT_plx "\n", val, addr); Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

The bdrv_set_geometry_hint call below is not needed - it's just setting what was just read. Signed-off-by: Bruce Rogers <brogers@novell.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23Replace calls of old bdrv_openKevin Wolf1-1/+1
What is known today as bdrv_open2 becomes the new bdrv_open. All remaining callers of the old function are converted to the new one. In some places they even know the right format, so they should have used bdrv_open2 from the beginning. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-04-23Make qemu-config available for toolsKevin Wolf2-2/+18
To be able to use config files for blkdebug, we need to make these functions available in the tools. This involves moving two functions that can only be built in the context of the emulator. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

vhost driver in qemu didn't ack features, and this happens to work because we don't really require any features. However, it's better not to rely on this.

2010-04-13sh_pci: fix memory and I/O accessAurelien Jarno1-96/+15
Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback interface changes"), the addresses passed to the I/O functions are an offset to the start of the area. As a consequence, there is no need to correct the address using the value of IOBR. This make possible the use of the default MMIO functions. Moreover the addresses are now remaped when the value if IOBR change. The memory area corresponds to the devices behing the PCI bus, it should not be mapped by the PCI controller. Remove the corresponding code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
