The changes to the packet class fix a long standing limitation where finding a packet that partially satisfied a request would cause a panic. This code remedies that limitation, although it should be in it's own changeset. src/mem/packet.cc <http://reviews.m5sim.org/r/910/#comment2171> This should be a separate change and doesn't need to be protected by a checker ifdef. The code is useful in all cases. src/mem/packet.cc <http://reviews.m5sim.org/r/910/#comment2172> Same as before. The comment should be updated to note that the partial read satisfy issue no longer exists. - Ali On 2011-11-23 15:07:45, Geoffrey Blake wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
