First I added some ioctl operations. Then I tried to do some DRM operations like test.c. This is successful when I use qemu-x86_64-static,but it failed when I use= qemu-i386-static. I can get some strace info like this: 403 openat(AT_FDCWD,"/dev/dri/card0",O_RDWR|O_LARGEFILE|O_CLOEXEC) =3D 4 403 ioctl(4,DRM_IOCTL_GET_CAP,{1,0}) =3D 0 ({1,1}) 403 ioctl(4,DRM_IOCTL_MODE_GETRESOURCES,{0,0,0,0,0,0,0,0,0,0,0,0}) =3D 0 = ({0,0,0,0,0,2,2,2,0,16384,0,16384}) 403 brk(NULL) =3D 0x40006000 403 brk(0x40027000) =3D 0x40027000 403 brk(0x40028000) =3D 0x40028000 403 ioctl(4,DRM_IOCTL_MODE_GETRESOURCES,{0,1073766816,1073766832,10737668= 48,0,2,2,2,0,16384,0,16384}) =3D -1 errno=3D14 (Bad address) And there are similar errors in other self driven operations. I want to know if it is QEMU's problem, so I hope to get some help. = Thank you! To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1894071/+subscriptions
