From d906bb68c3be218046d257c6870c9636e0e198cf Mon Sep 17 00:00:00 2001 From: Julius Werner <jwerner@chromium.org> Date: Tue, 16 May 2017 13:54:18 -0700 Subject: cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logs The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)
