Issue #12 has been updated by Martin Roth. Status changed from New to Closed Closing as fixed. ---------------------------------------- Bug #12: Use of CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL is a mess https://ticket.coreboot.org/issues/12#change-1349 * Author: Martin Roth * Status: Closed * Priority: Normal * Start date: 2015-11-27 ---------------------------------------- In Kconfig, the symbol MAINBOARD_POWER_ON_AFTER_POWER_FAIL is used in a few platforms. It is a bool. Because it's used in only a few mainboards, for MOST platforms, it's going to be defined as 0 (kconfig bools in coreboot are ALWAYS defined) Here are those mainboards:

src/mainboard/samsung/lumpy/Kconfig src/mainboard/samsung/stumpy/Kconfig src/mainboard/asus/kgpe-d16/Kconfig src/mainboard/asus/kfsn4-dre/Kconfig src/mainboard/asus/kfsn4-dre_k8/Kconfig src/mainboard/msi/ms9652_fam10/Kconfig

In a number of other platforms, CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL is used as if it were a standard #define - with three states: from src/southbridge/intel/bd82x6x/pch.h: <pre><code class="c"> #define MAINBOARD_POWER_OFF 0 #define MAINBOARD_POWER_ON 1 #define MAINBOARD_POWER_KEEP 2 #ifndef CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL #define CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL MAINBOARD_POWER_ON #endif </code></pre> Similar patterns are seen in these files:

src/southbridge/amd/agesa/hudson/sm.c src/southbridge/amd/amd8111/acpi.c src/southbridge/amd/pi/hudson/sm.c src/southbridge/amd/sb600/sm.c src/southbridge/amd/sb700/sm.c src/southbridge/amd/sb800/sm.c src/southbridge/intel/bd82x6x/pch.h src/southbridge/intel/fsp_bd82x6x/pch.h src/southbridge/intel/fsp_i89xx/pch.h src/southbridge/intel/fsp_rangeley/soc.h src/southbridge/intel/i3100/lpc.c src/southbridge/intel/i82801dx/i82801dx.h src/southbridge/intel/i82801ex/lpc.c src/southbridge/intel/i82801gx/i82801gx.h src/southbridge/intel/i82801ix/i82801ix.h src/southbridge/intel/ibexpeak/pch.h src/southbridge/intel/lynxpoint/pch.h src/southbridge/nvidia/ck804/lpc.c src/southbridge/nvidia/mcp55/lpc.c src/southbridge/sis/sis966/lpc.c src/southbridge/via/vt8237r/vt8237r.h src/superio/nuvoton/nct5572d/superio.c

To fix: * Make sure definitions are the same across all the platforms and fix them to be consistent if they're not already: ** 0 = power off, 1 = power on, 2 = restore previous state * Add Kconfig symbols to show which platforms get these options based on which platforms are using the option - Everything using CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL needs to be set. ** HAVE_POWER_STATE_ON_AFTER_FAIL - This gets set for platforms that get the option ** HAVE_POWER_STATE_RESTORE - This gets set for platforms that can actually restore the previous state * Turn the MAINBOARD_POWER_ON_AFTER_POWER_FAIL bool into a choice menu and move it to a higher level in the Kconfig tree. * Add the HAVE_POWER_STATE_ON_AFTER_FAIL and HAVE_POWER_STATE_RESTORE to the correct Kconfigs * Remove all of the existing #define stuff from the above files. * Remove the current MAINBOARD_POWER_ON_AFTER_POWER_FAIL Kconfig options from their current locations (with the exception of setting new defaults) * Test. -- You have received this notification because you have either subscribed to it, or are involved in it.
