Subject: [PATCH] Not-for-merge: ARM: config: omap: Disable SMP for AM335x
|
||||
build
|
||||
|
||||
SMP and SMP_ON_UP introduces some extra barriers and code many fast paths
|
||||
including kernel lock functions.
|
||||
|
||||
Performance sensitive usecases like networking gets impacted because of this.
|
||||
In typical production kernel which is targeted for single core device
|
||||
like AM335x family, you don't want to take this hit.
|
||||
|
||||
Ideally one should just create a device specific config feed as done by all
|
||||
typical distro's. Other option is to apply this specifically during build
|
||||
time using recipe.
|
||||
|
||||
Whichever option, one definitely don't want this overhead for performance
|
||||
critical usecases.
|
||||
|
||||
Disabling SMP in the build introduces one warining in cpuidle44xx.c driver
|
||||
and fix is included in the series
