I stumbled on this limitation as well when trying to build the
kernel on
a Libre Computer rk3399-pc board with only 4GiB of RAM, there I just
created a swapfile and it managed to proceed, a bit slowly, but worked
as well.
Here, it hits the VM space limit (3 G).
right, in my case it was on a 64-bit system, so just not enough memory,
not address space.
Please let me know if what is in the 'next' branch of:
https://git.kernel.org/pub/scm/devel/pahole/pahole.git
Works for you, that will be extra motivation to move it to the master
branch and cut 1.28.
on 64bit (-j1):
* master: 3.706 GB
(* master + my changes: 3.559 GB)
* next: 3.157 GB
on 32bit:
* master-j1: 2.445 GB
* master-j16: 2.608 GB
* master-j32: 2.811 GB
* next-j1: 2.256 GB
* next-j16: 2.401 GB
* next-j32: 2.613 GB
It's definitely better. So I think it could work now, if the thread
count
was limited to 1 on 32bit. As building with -j10, -j20 randomly fails on
random machines (32bit processes only of course). Unlike -j1.
Cool, I just merged a patch from Alan Maguire that should help with the
parallel case, would be able to test it? It is in the 'next' branch:
Not much helping.
On my box (as all previous runs):
next-j1 2.242
next-j16 2.808
next-j32 2.646
On a build host:
next-j1: 2.242
next-j16: 2.824
next-j20: 2.902 (crash)
next-j32: 2.902 (crash)
So I disabled BTF on all 32bits (arm+i586) in openSUSE Tumbleweed for
now. Better kernel without BTF, than no kernel at all 8-).
If you have ideas to force -j1 on 32bit, I can reenable/retest...
thanks,
