Re: [Gems-users] Using Magic Instruction on sparc64-linux

["Liqun Cheng" <liqun.cheng@xxxxxxxxx>]

Gene,

We used magic instruction on bagle sucessfully. The problem is magic-breakpoint-enable (on linux?) will only be triggered when the value of g0 is 0x40000. 

So you need either use "sethi 0x40000, %g0", or write a handler by yourself. Here is my python script, you can use it as a reference.

Cheers

@def call_back_1(cpu):
   pr("call back triggered\n")

@def hap_callback(user_arg, cpu, arg):
   eax = cpu.eax
   if eax == 1:
      call_back_1(cpu)
   else:
      print "Unknown callback"

@SIM_hap_add_callback("Core_Magic_Instruction", hap_callback, None)
