It also maintains a checksum 1032 of the trace records (even if space is exhausted) so that the 1033 sequence of I/O accesses can be verified. 1034 1035 When debugging drivers it is useful to see what I/O accesses were 1036 done and in what order. 1037 1038 Even if the individual accesses are of little interest it can be 1039 useful to verify that the access pattern is consistent each time 1040 an operation is performed. In this case a checksum can be used to 1041 characterise the operation of a driver. The checksum can be compared 1042 across different runs of the operation to verify that the driver is 1043 working properly. 1044 1045 In particular, when performing major refactoring of the driver, where 1046 the access pattern should not change, the checksum provides assurance 1047 that the refactoring work has not broken the driver. 1048 1049 This works by sneaking into the io.h heder for an architecture and 1050 redirecting I/O accesses through iotrace's tracing mechanism. 1051 1052 For now no commands are provided to examine the trace buffer. The 1053 format is fairly simple, so 'md' is a reasonable substitute. 1054 1055 Note: The checksum feature is only useful for I/O regions where the 1056 contents do not change outside of software control. Where this is not 1057 suitable you can fall back to manually comparing the addresses. It 1058 might be useful to enhance tracing to only checksum the accesses and 1059 not the data read/written. 1060 1061config CMD_I2C 1062 bool "i2c" 1063 help 1064 I2C support. 1065 1066config CMD_W1 1067 depends on W1 1068 default y if W1 1069 bool "w1 - Support for Dallas 1-Wire protocol" 1070 help 1071 Dallas 1-wire protocol support 1072 1073config CMD_LOADB 1074 bool "loadb" 1075 default y 1076 help 1077 Load a binary file over serial line. 1078 1079config CMD_LOADS 1080 bool "loads" 1081 default y 1082 help 1083 Load an S-Record file over serial line 1084 1085config CMD_LSBLK 1086 depends on BLK 1087 bool "lsblk - list block drivers and devices" 1088 help 1089 Print list of available block device drivers, and for each, the list 1090 of known block devices. 1091 1092config CMD_MBR 1093 bool "MBR (Master Boot Record) command" 1094 select DOS_PARTITION 1095 select HAVE_BLOCK_DEVICE 1096 help 1097 Enable the 'mbr' command to ready and write MBR (Master Boot Record) 1098 style partition tables. 1099 1100config CMD_MISC 1101 bool "misc" 1102 depends on MISC 1103 help 1104 Enable the command "misc" for accessing miscellaneous devices with 1105 a MISC uclass driver.
