[Patch] Optimize AES and GHASH for PowerPC64 (support little-endian and big-endian)
by Maamoun TK 01 Jul '20

01 Jul '20

Patch implementation benchmark for GCM_AES (Tested on POWER8): little-endian: - Encrypt x~17.5 of nettle C implementation - Decrypt x~17.5 of nettle C implementation - Update x~30 of nettle C implementation big-endian: - Encrypt x~18.5 of nettle C implementation - Decrypt x~18.5 of nettle C implementation - Update x~28.5 of nettle C implementation I investigated falling back to process 4 blocks instead of 8 blocks, 8x loop outperform 4x loop by x~1.22 on POWER8. Processing 4 blocks leaves plenty of registers on the table, to reduce the performance margin these registers can be used to overlap the instructions inside the loop. GHASH loop has two separate operations: - Digest calculation - Reduction The reduction procedure is hardly parallelized, to overcome that, the two procedures can overlap as follows |`````````````````````````````````````````| |Head: | |Digest calculation [0..3] | |`````````````````````````````````````````| |Loop: | |Overlapped Reduction [i+0..i+3] and | |Digest calculation [i+4..i+7] | |`````````````````````````````````````````| |Tail: | |Reduction [i+4..i+7] | ``````````````````````````````````````````` With that implemented the performance margin is reduced to x~1.15 and the code is messed up a little bit I can do more documentations so the reader can still keep track of what's going on but with that said the performance margin is still considerable and I think it's better to stick with 8x loop. - The patch passed the testsuite for both ppc64 and ppc64el. --- Makefile.in | 2 +- asm.m4 | 17 +- config.m4.in | 1 + configure.ac | 12 + gcm.c | 19 +- powerpc64/aes-decrypt-internal.asm | 584 +++++++++++++++++++++ powerpc64/aes-encrypt-internal.asm | 545 +++++++++++++++++++ powerpc64/gcm-hash8.asm | 1015 ++++++++++++++++++++++++++++++++++++ powerpc64/machine.m4 | 0 testsuite/gcm-test.c | 23 + 10 files changed, 2214 insertions(+), 4 deletions(-) create mode 100644 powerpc64/aes-decrypt-internal.asm create mode 100644 powerpc64/aes-encrypt-internal.asm create mode 100644 powerpc64/gcm-hash8.asm create mode 100644 powerpc64/machine.m4 diff --git a/Makefile.in b/Makefile.in index 64ff1001..fdc819f1 100644 --- a/Makefile.in +++ b/Makefile.in @@ -603,7 +603,7 @@ distdir: $(DISTFILES) done set -e;

[PATCH] Add ppc64 and ppc64el to Gitlab CI
by Maamoun TK 30 Jun '20

30 Jun '20

To run tests on ppc64 and ppc64el, this patch install cross building packages for both architectures on the Debian image, these packages will be install every time the CI triggered. A proper fix would be to install these packages to the image directly. This patch follows a different approach to get access LD shared library for qemu. Other architectures install native libc6 packages while both ppc64 and ppc64el install cross libc6 packages and export QEMU_LD_PREFIX to point to LD path which is more reasonable. .gitlab-ci.yml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 9f3b5c63..7f12ecfa 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -139,6 +139,11 @@ Debian.cross.x86: before_script: # remove any previously installed nettle headers to avoid conflicts - for arch in armhf mips arm64;do apt-get remove -y nettle-dev:$arch;done + - host="${CI_JOB_NAME#*.cross.}" + - if [ "$host" == "powerpc64-linux-gnu" ];then apt-get update && apt-get install -y gcc-$host && + apt-get install -y g++-$host && apt-get install -y libstdc++6-ppc64-cross && export QEMU_LD_PREFIX=/usr/$host;fi + - if [ "$host" == "powerpc64le-linux-gnu" ];then apt-get update && apt-get install -y gcc-$host && + apt-get install -y g++-$host && apt-get install -y libstdc++6-ppc64el-cross && export QEMU_LD_PREFIX=/usr/$host;fi script: - build=$(dpkg-architecture -qDEB_HOST_GNU_TYPE) - host="${CI_JOB_NAME#*.cross.}" @@ -162,3 +167,7 @@ Debian.cross.mips-linux-gnu: <<: *Debian_cross_template Debian.cross.aarch64-linux-gnu: <<: *Debian_cross_template +Debian.cross.powerpc64-linux-gnu: + <<: *Debian_cross_template +Debian.cross.powerpc64le-linux-gnu: + <<: *Debian_cross_template

FYI: Forced update of master-updates
by nisse＠lysator.liu.se 27 Jun '20

Hi, I tried out a microoptimization of the arm neon implementation of chacha and salsa20. Gave a 10% speedup on the older Cortex-A5 core, but unclear if it's an improvement overall, so I don't want to push it to master, and I've removed that commit from master-updates (now on its own branch arm-salsa20-chacha-vsra instead, in case anyone is curious). I'm considering changing the internal _salsa20_core and _chacha_core to do more than one block at a time, since processing a few blocks in parallel has a great potential for performance improvements.

PPC64LE optimizing AES and GHASH
by Maamoun TK 20 Jun '20

20 Jun '20

I added a PowerPC64LE optimized version of AES and GHASH to nettle. Patch summary: GHASH Algorithm I took the advantage of several references and researches to achieve the high-speed implementation of this algorithm. These references include several techniques that have been used to improve the performance of the algorithm, I will summarize the important techniques used as follows: - The main equation: The main equation for 4 block (128-bit each) can be seen in reference [1] Digest = (((((((Digest⊕C0)*H)⊕C1)*H)⊕C2)*H)⊕C3)*H = ((Digest⊕C0)*H4)⊕(C1*H3)⊕(C2*H2)⊕(C3*H) to achieve more parallelism, this equation can be modified to address 8 blocks per one loop. It looks like as follows Digest = ((Digest⊕C0)*H8)⊕(C1*H7)⊕(C2*H6)⊕(C3*H5)⊕(C4*H4)⊕(C5*H3)⊕(C6*H2)⊕(C7*H) - Handling Bit-reflection of the multiplication product [1]: This technique moves part of the workload inside the loop to the init function so it is executed only once. - Karatsuba Algorithm: This algorithm allows to perform three multiplication instructions instead of four, in exchange for two additional Xor. This technique is well explained with figures in reference [1] - Deferred Recombination of partial products This technique is well explained with figures in reference [1] - Multiplication-based reduction: I tested both classical shift-based reduction and multiplication-based reduction, the multiplication-based reduction achieved better performance and less instructions. Example of both reductions can be seen in reference [2] AES Power ISA makes it easy to optimize AES by offering built-in AES instructions. AES-GCM performance (Tested on POWER9): - GCM_AES Encrypt ~x13.5 of nettle C implementation - GCM_AES Decrypt ~x13.5 of nettle C implementation - GCM_AES Update (Only GHASH is called) ~x26 of nettle C implementation Notes: - Test 128 bytes is added to gcm-test in testsuite to test 8x loop in GHASH optimized function. - Since the functionality of gcm_set_key() is replaced with gcm_init_key() for PowerPC64LE, two warnings will pop up: [‘gcm_gf_shift’ defined but not used] and [‘gcm_gf_add’ defined but not used] References: [1] https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/c… [2] https://www.intel.com/content/dam/www/public/us/en/documents/software-suppo… [3] https://software.intel.com/file/24918 [4] https://github.com/dot-asm/cryptogams

Post patch on nettle-bugs list

Is there a limit to the number of lines of a message posted on the list or special option that should be passed to git diff? I created a patch with command "git diff --stat --summary --patch HEAD~1 > patch.patch", when I posted this patch on the list nothing happened.
