Add logging for each part of the boot process, using a new Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Igor Opaniuk

log: Add filter flag to match greater than a log level

2020-10-30T14:55:26Z

This is the complement of the existing behavior to match only messages with a log level less than a threshold. This is primarily useful in conjunction with LOGFF_DENY. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

log: Add filter flag to deny on match

2020-10-30T14:55:26Z

Without this flag, log filters can only explicitly accept messages. Allowing denial makes it easier to filter certain subsystems. Unlike allow-ing filters, deny-ing filters are added to the beginning of the filter list. This should do the Right Thing most of the time, but it's less-universal than allowing filters to be inserted anywhere. If this becomes a problem, then perhaps log_filter_add* should take a filter number to insert before/after. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

log: Add function to create a filter with flags

2020-10-30T14:55:26Z

This function exposes a way to specify flags when creating a filter. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

log: Expose some helper functions

2020-10-30T14:55:26Z

These functions are required by "cmd: log: Add commands to manipulate filters" and "test: Add a test for log filter-*". Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

log: Add additional const qualifier to arrays

Both these arrays and their members are const. Fixes checkpatch complaint. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

log: Fix missing negation of ENOMEM

Errors returned should be negative. Fixes: 45fac9fc18 ("log: Correct missing free() on error in log_add_filter()") Signed-off-by: Sean Anderson Reviewed-by: Heinrich Schuchardt

log: correct and check array size of log categories

2020-10-27T21:04:15Z

The log command has led to NULL dereferences if an unknown category name name was used due to missing entries in the list of category names. Add compile time checks for the array sizes of log_cat_name and log_lvl_name to avoid future mishaps. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

log: allow for message continuation

2020-10-27T17:50:53Z

Some drivers use macro pr_cont() for continuing a message sent via printk. Hence if we want to convert printk messaging to using the logging system, we must support continuation of log messages too. As pr_cont() does not provide a message level we need a means of remembering the last log level. With the patch a pseudo log level LOGL_CONT as well as a pseudo log category LOGC_CONT are introduced. Using these results in the application of the same log level and category as in the previous log message. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass
