support for powerpc architecture

[Pintu79]

I tried to build it on my machine which is powerpc 64 bit little endian. I have ubuntu 16.04 OS. I got the following error- #error "No support for PowerPC 64 bit mode". I also tried with replacing the luajit lib folder with downloading the current one from github, but i am not succesful to build it. Is some extra steps required to build it on power pc architecture or is it missing the feature for powerpc

Yes, unfortunately upstream LuaJIT has no support for PPC64 at the moment. Can you try replacing bundled LuaJIT with https://github.com/PPC64/LuaJIT? If it is functional, I will at least make sure to document it as an option. Thanks.

replacing with this LuaJIT link, sysbench is working for me. below is the snapshot. ci@t2ctl:~/sysbench.install/bin$ ./sysbench --test=cpu --num-threads=80 --cpu-max-prime=500000 run WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options. WARNING: --num-threads is deprecated, use --threads instead sysbench 1.1.0-ec17d39 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options: Number of threads: 80 Initializing random number generator from current time

@Pintu79 may I ask you to run 'make test' on your machine as well to make sure Lua API is functional?

I have run the test, but one of the test case is failed. So, is it necessary to pass all the test cases. I run the sysbench for mysql workload also. It was running smoothly. I run it with oltp-read-only.lua and oltp-write-only.lua. It was running good. So, should I believe the result what i get after run. below is the snapshot of make test - ci@t2ctl:~/sysbench$ make test cd tests && make test make[1]: Entering directory '/home/ci/sysbench/tests' ./test_run.sh t/1st.t: passed t/api_basic.t: passed t/api_histogram.t: passed t/api_legacy_basic.t: skipped t/api_legacy_rand.t: passed t/api_legacy_sql.t: skipped t/api_rand.t: passed t/api_reports.t: passed t/api_sql_mysql.t: skipped t/api_sql_pgsql.t: skipped t/cmd_cleanup.t: passed t/cmd_help.t: passed t/cmdline.t: passed t/cmd_prepare.t: passed t/cmd_run.t: passed t/commands.t: passed t/drivers.t: passed t/drv_mysql.t: skipped t/drv_pgsql.t: skipped t/help_drv_mysql.t: passed t/help_drv_pgsql.t: skipped t/opt_help.t: passed t/opt_histogram.t: passed t/opt_luajit_cmd.t: failed --- t/opt_luajit_cmd.t +++ t/opt_luajit_cmd.t.err @@ -8,7 +8,7 @@ $ sysbench --luajit-cmd opt_luajit_cmd.lua sysbench * (glob)

Thanks, that failure is expected. I'll see what can be done to support PPC64 out of the box.

[akopytov]

I think I can fix PPC64 at least partially, but I need access to a ppc64le machine. I'm also happy to accept patches.
