Current map_sg stores trace message in a coarse manner. This extends it so that more detailed messages could be traced. The map_sg trace message looks like: map_sg: dev=0000:00:17.0 [1/9] dev_addr=0xf8f90000 phys_addr=0x158051000 size=4096 map_sg: dev=0000:00:17.0 [2/9] dev_addr=0xf8f91000 phys_addr=0x15a858000 size=4096 map_sg: dev=0000:00:17.0 [3/9] dev_addr=0xf8f92000 phys_addr=0x15aa13000 size=4096 map_sg: dev=0000:00:17.0 [4/9] dev_addr=0xf8f93000 phys_addr=0x1570f1000 size=8192 map_sg: dev=0000:00:17.0 [5/9] dev_addr=0xf8f95000 phys_addr=0x15c6d0000 size=4096 map_sg: dev=0000:00:17.0 [6/9] dev_addr=0xf8f96000 phys_addr=0x157194000 size=4096 map_sg: dev=0000:00:17.0 [7/9] dev_addr=0xf8f97000 phys_addr=0x169552000 size=4096 map_sg: dev=0000:00:17.0 [8/9] dev_addr=0xf8f98000 phys_addr=0x169dde000 size=4096 map_sg: dev=0000:00:17.0 [9/9] dev_addr=0xf8f99000 phys_addr=0x148351000 size=4096 Signed-off-by: Lu Baolu <baolu.lu@linux.intel.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
