Hi Kumar,
The mpc8360 and mpc8349 do not have a perfmon register (I don't find it
at all in the MPC8360RM and the mpc8349 errata I referenced says the
MPC8349RM is in error).
The result is that the assembler dies with an error. If the assembler
didn't die with an error, I presume the kernel would since it is an
invalid SPR.
CC arch/powerpc/kernel/pmc.o
{standard input}: Assembler messages:
{standard input}:7: Error: Unrecognized opcode: `mfpmr'
{standard input}:11: Error: Unrecognized opcode: `mtpmr'
make[1]: *** [arch/powerpc/kernel/pmc.o] Error 1
make: *** [arch/powerpc/kernel] Error 2
This is using ELDK4.1 (also 4.2rc) using the ppc_6xx- version of the
compiler (which symlinks to powerpc-linux-gcc).
If some of the mpc83xx processors have perfmon registers, we need a more
granular way of selecting the CONFIG_FSL_EMB_PERFMON option (or a Plan
B, but I don't know what Plan B would be).
Best regards,
gvb
