Ask yourself (and your AMC / Metrowerks sales guy) the following
questions:
* Does the PowerTAP documentation / sales guys claim to support Linux
as target OS? Especially is the MMU support good enough to debug
for example dynamically loaded kernel modules?
* How many people on this mailing list actually reported that they
have successfully used a PowerTAP to debug the Linux kernel
including dynamically loaded device drivers?
* Is there support for Linux as host OS?
* Does the Linux kernel provide special hooks for the PowerTAP
(equivalent to the CONFIG_BDI_SWITCH configuration option)?
* Which CPUs are supported by the PowerTAP? The BDI2000 supports
CPU32/32+, ColdFire, PowerPC, ARM, MIPS32, XScale and M-CORE ...
Guess what we're using...
