Hi,
I've compiled latest 2.6.29-andy-tracking kernel with ARM Fast Context
Switch Extension patch [1], using gta02_moredrivers_defconfig kernel
config and CONFIG_ARM_FCSE=y and CONFIG_ARM_FCSE_BEST_EFFORT=y
options. I've tested this kernel with latest SHR-unstable. System with
FCSE enabled is really faster. However some (mostly Python)
applications randomly segfaults during loading[3]. But when
application loads properly, it runs rock stable[4].
Seems, it isn't related to 32 MB virtual memory limit and best effort
mode, because applications running above this limit runs properly.
I also tested FCSE on Qt Moko v16 with nodebug v17 kernel, but Qte
always restarts when loading desktop.
ARM FSCE support is already included in Android on FreeRunner
distributon kernel. I like to see this included also in Openmoko
distributions kernels, when will be stable and ready.
I have readed your email, but I don't have time right now to take a look.
I'm going to add the original author of the patches. Maybe he can give
some hints
Michael
