Re: [Gems-users] Ruby for x86 machine

[Sitos Lin <sitos.lin@xxxxxxxxx>]

Hello:
  I attach Ruby to the x86 machine by following the same instructions
from the quick start:

instruction-fetch-mode instruction-fetch-trace
istc-disable
dstc-disable
cpu-switch-time 1
load-module ruby
ruby0.setparam g_NUM_PROCESSORS 1
ruby0.setparam g_MEMORY_SIZE_BYTES 4294967296
ruby0.init

  There is no instruction indicating which physical memory objects
ruby attach to. How can I attach ruby to a specific memory object?
Thank you.

Best regards,
  Sitos
