kernel/configs/no_smp.config
We are running into some issues with the no_smp.config, seems some kernel
sysfs items relating to CPU counts are misbehaving (Chirag has more details
if anyone is interested). Disabling SMP is not well tested in general anymore
as it is often enabled by default even for single-core systems. The very small
performance change is not worth the lack of testing and instability caused
by going with non-standard configurations IMHO.
Everything else here looks good, but could we drop no_smp.config for now
and take up a debate on adding it in at a later time?
This also has the side benefit of reducing our kernel builds from 6 variations
to just 4 (arm32/64 x rt/non-rt).
We only have 4 now... the no_smp was just added to ti33 and ti43 for backwards
compat to fix some issues. But we never did additional kernel builds because
of it...
What were the 6 variations you were referring to?
multi_v7_defconfig + ti_multi_v7_prune.config
multi_v7_defconfig + ti_multi_v7_prune.config + no_smp.config
multi_v7_defconfig + ti_multi_v7_prune.config + ti_rt.config
multi_v7_defconfig + ti_multi_v7_prune.config + no_smp.config + ti_rt.config
defconfig + ti_arm64_prune.config
defconfig + ti_arm64_prune.config + ti_rt.config
These are the variations, so without no_smp.config there would
only be 2 kernels across all am3/4/5, one with and one without RT.
On the side I've been working to make the kernel build into
one for all of aarch64 (i.e. one package in aarch64-oe-linux
vs kernel for each and every platform). Would like to do the
same for armv7.
