CONFIG_PROVE_LOCKING is an expensive option which adds significant overhead to lock operations. The examples are 5% power consumption increase for vexpress with this option enabled, and improving netperf on the loopback results by ~200% after disabling DEBUG_MUTEXES (DEBUG_MUTEXES is selected by PROVE_LOCKING). Move CONFIG_PROVE_LOCKING to a separate debug.conf fragment, so that it could be enabled only when it is needed. Signed-off-by: Andrey Konovalov <andrey.konovalov@linaro.org>
2013-03-18configs: linaro-base: Remove CONFIG_EXPERIMENTALJon Medhurst
Commit 3d374d09 (final removal of CONFIG_EXPERIMENTAL) removed CONFIG_EXPERIMENTAL from Linux. Signed-off-by: Jon Medhurst <tixy@linaro.org>
2013-03-12configs: linaro-base: Set CONFIG_PROC_DEVICETREE=yJon Medhurst
Both the Android and Ubuntu have QA tests which expect to be able to validate device-tree booting by looking in /proc/device-tree, so we should enable this for all Linaro builds. At the same time we can remove this option from ubuntu.conf as it's not an Ubuntu specific requirement. Signed-off-by: Jon Medhurst <tixy@linaro.org>
2013-03-12Enable the options needed to test CPU hotplug latencyAndrey Konovalov
Enable CONFIG_HOTPLUG in linaro-base.conf as all Linaro kernels should have it. Enabling CONFIG_DEBUG_FS and CONFIG_FUNCTION_TRACER add no runtime slowdown if not used, so having them in linaro-base.conf is OK too. Now that CONFIG_HOTPLUG and CONFIG_DEBUG_FS are in linaro-base.conf, remove them from ubuntu.conf. Signed-off-by: Andrey Konovalov <andrey.konovalov@linaro.org>
2013-03-12configs: linaro-base: set CONFIG_AEABI=yJon Medhurst
We already have CONFIG_THUMB2_KERNEL=y which also selects CONFIG_AEABI however if someone wanted to disable Thumb2 for debugging or other reasons then they may try simply removing the Thumb2 config entry. This however would then default to the old ABI and it seems there are some obscure bugs in this little tested kernel variant. So, to save wasting people's time let's make sure CONFIG_AEABI is explicitly selected. As we are adding this to linaro-base.conf we can remove it from android.conf (which probably had it as a leftover from when we had Thumb2 disabled). Signed-off-by: Jon Medhurst <tixy@linaro.org>
2013-03-12configs: Replace CONFIG_PERF_COUNTERS with CONFIG_PERF_EVENTSJon Medhurst
CONFIG_PERF_COUNTERS was removed in comit 392d65a9 (perf: Remove PERF_COUNTERS config option) Signed-off-by: Jon Medhurst <tixy@linaro.org>
2013-03-12configs: Make CONFIG_MODULES part of linaro-baseJon Medhurst
CONFIG_MODULE was in both Ubuntu and Android configs so it would be best if it is in the base config instead. Also, having CONFIG_MODULE_UNLOAD in will enable the Gator module to be upgraded to a later version via DKSM without rebooting, and allows for easier testing.
