ARC: Add perf support for ARC700 cores

2013-11-12T04:15:38Z

This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events are supported now. Signed-off-by: Mischa Jonker Acked-by: Peter Zijlstra Signed-off-by: Vineet Gupta

ARC: Hostlink Pseudo-Driver for Metaware Debugger

2013-02-15T17:46:10Z

This allows ARC Target to do I/O to host in absence of any peripherals whatsoever, assisted by Metaware Hostlink facility. Further we have a FUSE based filesystem which makes us mount/access host filesystem on target and do fops. Signed-off-by: Vineet Gupta

ARC: Unaligned access emulation

2013-02-15T17:46:06Z

ARC700 doesn't natively support unaligned access, but can be emulated -Unaligned Access Exception -Disassembly at the Fault address to find the exact insn (long/short) Also per Arnd's comment, we runtime control it using 2 sysctl knobs: * SYSCTL_ARCH_UNALIGN_ALLOW: Runtime enable/disble * SYSCTL_ARCH_UNALIGN_NO_WARN: Warn on each emulation attempt Originally contributed by Tim Yao Signed-off-by: Vineet Gupta Cc: Tim Yao Acked-by: Arnd Bergmann

ARC: SMP support

2013-02-15T17:46:02Z

ARC common code to enable a SMP system + ISS provided SMP extensions. ARC700 natively lacks SMP support, hence some of the core features are are only enabled if SoCs have the necessary h/w pixie-dust. This includes: -Inter Processor Interrupts (IPI) -Cache coherency -load-locked/store-conditional ... The low level exception handling would be completely broken in SMP because we don't have hardware assisted stack switching. Thus a fair bit of this code is repurposing the MMU_SCRATCH reg for event handler prologues to keep them re-entrant. Many thanks to Rajeshwar Ranga for his initial "major" contributions to SMP Port (back in 2008), and to Noam Camus and Gilad Ben-Yossef for help with resurrecting that in 3.2 kernel (2012). Note that this platform code is again singleton design pattern - so multiple SMP platforms won't build at the moment - this deficiency is addressed in subsequent patches within this series.
