This python script allows to pretty print 9p simpletrace logs and can be
further enhanced to filter 9p logs based on command line arguments.

Sample output:
 TGETATTR (tag = 1 , fid = 0 , request_mask = 0x7ff )
 RGETATTR (tag = 1 , result_mask = 0x7ff , mode = 040777 , uid = 500 , gid = 500 )
 TXATTRWALK (tag = 1 , fid = 0 , newfid = 1 , xattr name = 36832096 )
 RXATTRWALK (tag = 1 , xattrsize  = 18446744073709551555 )
 TXATTRWALK (tag = 1 , fid = 0 , newfid = 1 , xattr name = 36744768 )
 RXATTRWALK (tag = 1 , xattrsize  = 18446744073709551555 )
 TGETATTR (tag = 1 , fid = 1 , request_mask = 0x3fff )
 RGETATTR (tag = 1 , result_mask = 0x17ff , mode = 040777 , uid = 500 , gid = 500 )
 TWALK (tag = 1 , fid = 1 , newfid = 2 , nwnames = 1 )
 RWALK (tag = 1 , nwnames = 1 , qids = 0x230aea0 )
