Hi all,

So far we found 2 issues in the LuaJIT project :

light userdata problem on 48-bit VA kernel.

Currently, Zhongwei is looking into it. The plan is to get a workable solution and push to upstream to discuss the problem.

wrk doesn't work with LuaJIT.(Unknown cause, reproduced on SoftIron)

Currently, we don't have bandwidth to look into that.

So for the wrk related issue, it would be very appreciated if anyone can take a look.

Steps to reproduce the problem :

Build and install wrk

echo "===== Install libssl-dev which is needed by wrk"
apt-get -y install libssl-dev
echo "===== Download, build and install LuaJIT-2.1 which is also needed by wrk"
wget -O /root/LuaJIT-2.1.zip https://github.com/LuaJIT/LuaJIT/archive/v2.1.zip # having problems with both on upstream and linaro branches
unzip /root/LuaJIT-2.1.zip -d /root/
make PREFIX=/usr install -C /root/LuaJIT-2.1
ln -sf luajit-2.1.0-beta2 /usr/bin/luajit
echo "===== Download wrk"
wget -O /root/wrk-4.0.2.zip https://github.com/wg/wrk/archive/4.0.2.zip
unzip /root/wrk-4.0.2.zip -d /root/
echo "===== Patch wrk to use luajit-2.1 rather than luajit-2.0"
sed -i 's/luajit-2.0/luajit-2.1/g' /root/wrk-4.0.2/src/*
echo "===== Build and install wrk"
make WITH_LUAJIT=/usr WITH_OPENSSL=/usr -C /root/wrk-4.0.2
cp /root/wrk-4.0.2/wrk /usr/bin/

wrk -d 1s -c 1 http://www.google.com
