Hi, all
I test specint of aarch64 LP64 when aarch32 el0 disable/enabled respectively
and compare with ILP32 unmerged kernel(4.8-rc6) in our arm64 board. I found
that difference(ILP32 disabled/ILP32 unmerged) is bigger when aarch32 el0 is
enabled, compare with aarch32 el0 disabled kernel. And bzip2, mcg, hmmer,
libquantum are the top four differences[1]. Note that bigger is better in
specint test.
In order to make sure the above results, I retest these four testcases in
reportable way(reference the command in the end). The result[2] show that
libquantum decrease -2.09% after ILP32 enabled and aarch32 on. I think it is in
significant.
The result of lmbench is not stable in my board. I plan to dig it later.
[1] The following test result is tested through --size=ref --iterations=3.

Hi Bamvor, I'm surprised that you see this much difference from ILP32 patches on SPEC CPU2006int at all. The SPEC CPU2006 benchmarks spend almost no time in the kernel syscalls. I can imagine memory, TLB, and cache handling in the kernel could affect CPU2006 benchmarks. Do ILP32 patches touch code in those areas? Other than that, it would be interesting to check what the variance is between the 3 iterations of benchmark runs. Could you check what relative standard deviation is between the 3 iterations -- (STDEV(RUN1, RUN2, RUN3) / RUNselected)? For reference, in my [non-ILP32] benchmarking I see 1.1% for 401.bzip2, 0.8% for 429.mcf, 0.2% for 456.hmmer, and 0.1% for 462.libquantum. -- Maxim Kuvyrkov www.linaro.org > On Nov 17, 2016, at 7:28 AM, Zhangjian (Bamvor) <bamvor.zhangjian@huawei.com> wrote: > > Hi, all > > I test specint of aarch64 LP64 when aarch32 el0 disable/enabled respectively > and compare with ILP32 unmerged kernel(4.8-rc6) in our arm64 board.

Here is my result:
ILP32_merged ILP32_unmerged
401.bzip2 0.31% 0.26%
429.mcf 1.61% 1.36%
