MIPS Technologies Introduces hot spot kernel analyzer [LWN.net]

MIPS Technologies, Inc. has announced the Hot Spot Analyzer for profiling the Linux kernel. "With the Hot Spot Analyzer (HSA), software engineers can quickly identify program bottlenecks that are restricting system performance. The HSA builds on the unique Zero Overhead Program Counter (PC) Sampling feature built into the MIPS32(R) 24K(R), MIPS32(R) 34K(R) and MIPS32(R) 74K(TM) core families."

funny, other processors/development platforms already have this "feature".  sampling the PC
via high speed JTAG certainly isnt unique nor new.

Yeah, different tools/processors have been doing this for years - I think that Analog Devices
[full disclosure - that is where I work, but not on this product] won best embedded
development tool (EDN) for this type of feature in 2000 for their VDSP IDE:

The best picture I could find was slide ten:

The demo does not show a running kernel, but it is just an elf file to JTAG - it really
doesn't matter.

The only news here seems to be Eclipse integration (which is neat, but that is it).
