Display Native Interface and Read/Write Command History
Description:
This command displays the command history of the Native Interface and Read/Write
subsystem.
Input Parameters:
None
Output Data:
If an error occurred, the following information will be displayed.
"DiagError aaaaaaaa"
where
aaaaaaaa is the Diagnostic Error Code
If no error occurred, the Native Interface Command History will be displayed as follows.
"ATA ccc Cmds"
"Ts(ms) dT(ms) Op Cnt LBA"
"dddddddddd eeeeeeee ff gggg hhhhhhhhhhhh" * see remark below
where
ccc is the number of ATA commands to display. The oldest one is displaed first
dddddddddd is the time stamp(ms) of the ATA command when it was recorded
eeeeeeee is the time difference(ms) from the previous ATA command
ff is the ATA Op-code. For example, EC is for Identify Device command
gggg is the block count specified in the ATA task file
hhhhhhhhhhh is the LBA number specified in the ATA task file
The R/W Request History will be displayed as follows.
"RW iii Cmds"
"Ts(ms) dT(ms) xT(ms) Type Option Mode St EC Info"
"jjjjjjjjjj kkkkkkkk llllllll oo pppppp qqqqqq r ssssssss" ** see remark below
where
iii is the number of Read/Write commands to display. The oldest one is displayed first
jjjjjjjjjj is the time stamp(ms) of the Read/Write command when it was recorded
kkkkkkkk is the time difference(ms) from the previous Read/Write command.
If this is 99999999, it means the time difference is indeterminate
llllllll is the excution time duration for which the Read/Write request ran.
If this is 99999999, it means the excution time is indeterminate
