i'd like to only do this on arm, not on x86
Sure, I can look into that. Might not be so easy in the Makefile. |

looks good to me too, thank you 👑
Fixes #6742.
This PR sets
JEMALLOC_SYS_WITH_LG_PAGE
to 16 for aarch64 cross builds, which will force jemalloc to use 64 KiB pages. This should work with most of the newer arm64 systems which use larger pages. This is an alternative to:I have tested this myself by running
make docker-build-push
on an x86_64 system. I pulled the image (which I pushed to my local docker hub account) on my M1 Mac mini running Linux and it works.Initially, setting the environment variable didn't seem to work. I realized that environment variables weren't being passed to
cross build
, which makes sense because it's a docker container. I had to configure passthrough variables.Link: https://docs.rs/crate/cross/0.1.14
This PR also re-enables jemalloc to be a default feature.
