Oprofile operf is not collecting any data -



Oprofile operf is not collecting any data -

i testing oprofile version 1.0.0 out on 2 identical machines. on 1 works on other not collect info @ all. oprofile downloaded source , compiled , installed on each box - same version of libraries/compiler etc

as root running , exiting recommended ctrl-c

operf --system-wide

kernel on both boxes is

2.6.32-279.el6.x86_64 #1 smp fri jun 22 12:19:21 utc 2012 x86_64 x86_64 x86_64 gnu/linux

there difference in cpu's - working operf box

vendor_id : genuineintel cpu family : 6 model : 15 model name : intel(r) xeon(r) cpu 5160 @ 3.00ghz stepping : 6 cpu mhz : 2992.426

this non working box

vendor_id : genuineintel cpu family : 15 model : 4 model name : intel(r) xeon(tm) cpu 3.80ghz stepping : 10 cpu mhz : 3790.625

even if 2nd cpu not supporting hardware profiling (not sure flags for) there way create work - mentions oprofile can't performance data using timer mode opcontrol gone in version 1.0

assembly - What is the addressing mode for ld, add, and rjmp instructions? -

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
