Linux: Select `GOOGLE_MEMCONSOLE_COREBOOT` for coreboot console log under `/sys` #616

pmenzel · 2018-02-16T07:05:25Z

Loading memconsole_coreboot will expose the coreboot log messages under /sys/firmware/log. The logs can still be retrieved with sudo cbmem -c.

The text was updated successfully, but these errors were encountered:

Remove `CONFIG_CMDLINE="init=/bin/systemd"` [1], and build the module, enabling access to the coreboot console stored in CBMEM (coreboot memory). [1] #621 Fixes: #616

Build the module *memconsole_console*, enabling access to the coreboot console messages stored in CBMEM (coreboot memory). > This option enables the kernel to search for a firmware log in the > coreboot table. If found, this log is exported to userland in the > file /sys/firmware/log. Fixes: #616
