[gem5-users] Help to understand memory trace
Hello Users, I am analyzing the memory access pattern of a benchmark. For which i have connected the communication monitor between cpu and dcache and obtained the trace. The snippet of trace looks like below. w,2174471252,4,66,850031503453000 w,2174471256,4,66,850031503453250 w,2174471260,4,66,850031503453500 r,2282845416,4,74,850031503516750 r,4017452700,4,74,850031503518250 u,4017452700,4,2097218,850031503521500 u,4017452700,4,2097218,850031503524000 w,2174471204,4,66,850031503531500 Here i could see some packet are marked with commands 'u'(not read nor write). What does this mean? Also i am trying to understand the flag values(66, 74, 2097218). Can anyone help me in understanding what do these flag values indicate?

Re: [gem5-users] Help to understand memory trace
Hi Prathap. Have a look at src/proto/packet.proto. The ASCII output is not really intended to be used for anything besides “checking”. The fields in the trace correspond to the enums in src/mem/packet.hh and src/mem/request.hh Andreas From: gem5-users gem5-users-boun...@gem5.orgmailto:gem5-users-boun...@gem5.org on behalf of Prathap Kolakkampadath kvprat...@gmail.commailto:kvprat...@gmail.com Reply-To: gem5 users mailing list gem5-users@gem5.orgmailto:gem5-users@gem5.org Date: Wednesday, 1 July 2015 11:53 To: gem5 users mailing list gem5-users@gem5.orgmailto:gem5-users@gem5.org Subject: [gem5-users] Help to understand memory trace Hello Users, I am analyzing the memory access pattern of a benchmark.
