I'm a bit worried we're going around in circles with this. We did have a different form of tests a while back but I was told those didn't work well and they were replaced with the current setup which worked with the driver in the glibc source code. This was done around the time we added support for the other toolchain test suites (binutils+gcc). We ended up with options to use full system qemu or user mode qemu emulation depending on the speed of the target (e.g. with kvm or not). Has this patchset been run with all the tests in glibc or just a subset? I'm always very nervous about having two ways to do similar things. Cheers, Richard
