At the moment, the following checkpoints are implemented: -- Detailed boot stage timing - CONFIG_BOOTSTAGE - Define this option to get detailed timing of each stage - of the boot process. - - CONFIG_BOOTSTAGE_USER_COUNT - This is the number of available user bootstage records. - Each time you call bootstage_mark(BOOTSTAGE_ID_ALLOC, ...) - a new ID will be allocated from this stash. If you exceed - the limit, recording will stop. - - CONFIG_BOOTSTAGE_REPORT - Define this to print a report before boot, similar to this: - - Timer summary in microseconds: - Mark Elapsed Stage - 0 0 reset - 3,575,678 3,575,678 board_init_f start - 3,575,695 17 arch_cpu_init A9 - 3,575,777 82 arch_cpu_init done - 3,659,598 83,821 board_init_r start - 3,910,375 250,777 main_loop - 29,916,167 26,005,792 bootm_start - 30,361,327 445,160 start_kernel - - CONFIG_CMD_BOOTSTAGE - Add a 'bootstage' command which supports printing a report - and un/stashing of bootstage data. - - CONFIG_BOOTSTAGE_FDT - Stash the bootstage information in the FDT. A root 'bootstage' - node is created with each bootstage id as a child. Each child - has a 'name' property and either 'mark' containing the - mark time in microsecond, or 'accum' containing the - accumulated time for that bootstage id in microseconds. - For example: - - bootstage { - 154 { - name = "board_init_f"; - mark = <3575678>; - }; - 170 { - name = "lcd"; - accum = <33482>; - }; - }; - - Code in the Linux kernel can find this in /proc/devicetree.
