CJDNS Version bump - (Testing Needed)

[darkdrgn2k]

Talked to CJD and confirmed that the -O2 issue is fixed ( Issue #165 )

Can we test to confirm its fixed.

[darkdrgn2k]

Test using raspberry pi 3b using tbase100 Ethernet gcc (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516

Clear over ipv4

[benhylau]

What is this on?

CJDNS binary compiled with prototype on sudo CFLAGS="-march=armv8-a+crc -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard" ./do

If it's rpi3b why is it so slow?

[benhylau]

Can we test to confirm its fixed.

What needs to happen before we can merge this?

[darkdrgn2k]

-O2 issues seems to be fixed CJDNS is preforming really poorly (not meeting recorded benchmarks at all.

Two things we should check

• Test past versions of CJDNS to see if they can preform as well ass they used to

• [ ] Initial TAG_CJDNS=cjdns-v19.1

• [ ] Oct 28, 2017 TAG_CJDNS=186169f9a8631633795e4e9d70c501519a7800f4

• [ ] Current Develop d2e55d58548d83940482fe1bbbe1fd36f7f1b4ef

• [ ] Proposed Fix a86c3e147b5e3eefbbe2c94c8c5aded57e3dfbaf

• Test compile strings from previous releases to see if that is the issue

• [ ] Initial CJDNS_BUILD_CMD="sudo NO_TEST=1 CFLAGS=\"-march=armv8-a+crc -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard\" ./do"

• [ ] Oct 28 2017 CJDNS_BUILD_CMD="sudo CFLAGS=\"-march=armv8-a+crc -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard -O2\" ./do"

• [ ] -O2 Workaround - CJDNS_BUILD_CMD="sudo CFLAGS=\"-march=armv8-a+crc -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard -O2\" ./do"

• [ ] Proposed Fix CJDNS_BUILD_CMD="sudo CFLAGS=\"-march=armv8-a+crc -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard\" ./do"

Test where done against a i7 test point

• Test Pi 3 and 3b+ to see if thats the issue

• Test to see if IPFS is hogging the cpu more then it used to

[darkdrgn2k]

Needs nodejs installed (apt-get install -y nodejs)

Phase one compile script

[makew0rld]

What's going on with this now? What CJDNS version should we update too and test now?

[makew0rld]

Do we want to do something with this before #291 gets merged?

[darkdrgn2k]

Do we want to do something with this before #291 gets merged?

Depends if we can get an answer.. right now its an enigma!

[benhylau]

Shall we merge this for v0.4?

bumped to latest because it would not compile anymore
