When I use qemu-i386 and interact with the video card device,an error has occurred: 18534 ioctl(4,DRM_IOCTL_MODE_GETENCODER,{39,0,0,0,0}) = 0 ({39,4,34,3,0}) 18534 ioctl(4,DRM_IOCTL_MODE_CREATE_DUMB,{1080,1920,32,0,0,0,0}) = 0 ({1080,1920,32,0,1,7680,8294400}) 18534 ioctl(4,DRM_IOCTL_MODE_ADDFB,{0,1920,1080,7680,32,24,1}) = 0 ({66,1920,1080,7680,32,24,1}) 18534 ioctl(4,DRM_IOCTL_MODE_MAP_DUMB,{1,0,0}) = 0 ({1,0,5543018496}) 18534 mmap2(NULL,8294400,PROT_READ|PROT_WRITE,MAP_SHARED,4,0x14a63c) = -1 errno=22 (Invalid argument) "5543018496" is the offset through ioctl() and it is "0x14a63c000". In qemu: ret = target_mmap(arg1, arg2, arg3, target_to_host_bitmask(arg4, mmap_flags_tbl), arg5, arg6 << MMAP_SHIFT); The type of "arg6" is ulong.When use qemu-i386, arg6 can't be set to "0x14a63c000".So it's wrong for my program. I want to find a good way to deal with this kind of problem, but I'm not very familiar with QEMU, so I came to ask how to deal with this problem. Thank you!
