Hi, I mostly use QEMU but Thunder X CPU works similarly. I also noticed that some tests fail sporadically, and some fail only in scenario. The current fail list, as for me, is at the bottom.
Below links to my sources.

It has few bugfixes: https://github.com/norov/glibc/tree/new-api

https://github.com/norov/linux/tree/pin1 This branch is v4.5 plus - Andrew's Thunder X patches (not mandatory); - http://comments.gmane.org/gmane.linux.kernel/2116021 - http://comments.gmane.org/gmane.linux.kernel/2162853 - current ILP32 (RFC5 + few fixes)

I use one Andrew gave me. AFAIK, he's preparing useful package. Andrew?
I use this cross-toolchain. Find sys-root under aarch64-thunderx-linux-gnu/ https://drive.google.com/file/d/0B93nHerV55yNdXBlVTRLNzF0aFE/view?usp=sharing

Find LTP here: https://drive.google.com/file/d/0B93nHerV55yNSTlZX3drRTBCaEU/view?usp=sharing
Notice that I configure it with command: echo $(PREFIX) /home/yury/work/toolchain/thunderx-tools/ ./configure --host=aarch64 --prefix=/home/yury/work/ltp/ltp \ CC=$(PREFIX)/bin/a arch64-thunderx-linux-gnu-gcc \ AR=$(PREFIX)/bin/aarch64-thunderx-linux-gnu-ar \ STRIP =$(PREFIX)/bin/aarch64-thunderx-linux-gnu-strip \ RANLIB=$(PREFIX)/bin/aarch64-thunderx-linux-gnu-ranlib \ CFLAGS=-mabi=ilp32 \ LDFLAGS=-mabi=ilp32 -Wl,--rpath=/root/sys-root/libilp32 \ -Wl,--dynamic-linker=/root/sys-root/libilp32/ld-2.21.90.so
Notice that you don't need to place experimental sys-root to system paths, but path is hardcoded to '/root/sys-root'

I already told there's mess there, and I'd prefer to make things work first and then do cleanup.
