With nvmodel -m2 make -j6 use only 4 cores

[vondalej]

So glad I just flashed 4.3 rather than wait for this to get fixed…

[vondalej]

crickets…

[laurent.delaon]

what is it ???

[vondalej]

I’m still waiting for a fix. Jetpack 4.4 turns the TX2 into a worse performer than the nano by disabling 1/3 of the system.

[JDSchroeder]

Is NVIDIA going to fix this?
OR
Is the plan to leave it as it is for all future JetPack releases and force customers to make the described change if they want to run processes on the Denver cores?

[vondalej]

It’s NOT fixed though. An update undoes the fix.

Hi,
Please refer to

Cannot enable denver cores for TX2 (Jetpack 4.4 DP)

Hi, Please check 5.16 Increased Kernel Launch Latency on Denver 2 Cores in release notes of r32.4.3. Due to the concern, we disable Denver cores by default. For leveraging Denver cores, please execute sudo nvpmodel -m 0 and taskset: https://man7.org/linux/man-pages/man1/taskset.1.html For using core #1, please set 0x2: $ taskset 0x2 <_USER_APPLICATION_> & For using core #2, please set 0x4: $ taskset 0x4 <_USER_APPLICATION_> & We have worked out a solution. Please check this comment.
