Hi Efraim,
can you help me getting the support for transparent huge page on aarch64
for jemalloc into Guix?
https://lists.gnu.org/archive/html/guix-patches/2023-02/msg00698.html
I'm using those patches locally and have tested it so far by:
- Compiling the whole Rust toolchain
- Using this Rust toolchain to compile Icecat and a Rust Linux kernel
module for thr GPU
I haven't noticed any issues so far.
Thanks, Roman.
