Re: [Qemu-devel] [PATCH v6 3/4] vfio: vfio-pci device assignment driver

[Alex Barcelo]

This:

    struct vfio_iommu_type1_dma_map map = {
        .argsz = sizeof(map),
        .flags = VFIO_DMA_MAP_FLAG_READ,
        .vaddr = (__u64)vaddr,
        .iova = iova,
        .size = size,
    };

(around line 771)

breaks in my environment. I am in a crosschain environment on a i386
buildin PPC (32bit) binaries. I am using emdebian utilities, and have
been cross building qemu for months now.

The configure:
PKG_CONFIG_PATH=/usr/powerpc-linux-gnu/lib/pkgconfig ./configure
--prefix=/mnt/DATA/DARCO/alien --enable-debug-tcg --enable-debug
--enable-trace-backend=simple --disable-strip --disable-kvm
--enable-profiler --target-list=i386-softmmu --static --disable-curl
--cross-prefix=powerpc-linux-gnu- --with-coroutine=sigaltstack

The build:
make clean && make -j && make install

The error:
/mnt/DATA/DARCO/qemu-git/hw/vfio_pci.c: In function 'vfio_dma_map':
/mnt/DATA/DARCO/qemu-git/hw/vfio_pci.c:771: error: cast from pointer
to integer of different size
