2019-04-05libpayload: Align main() data typesPatrick Georgi
One of many steps to compile with -Wconversion, as unsigned int and int aren't the same thing. BUG=b:111443775 BRANCH=none TEST=make junit.xml shows fewer warnings with -Wconversion enabled Change-Id: I9673ca70da32a1e5117b27fa89167e03379af9c1 Signed-off-by: Patrick Georgi <pgeorgi@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32183 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>

2018-09-12libpayload/arch/x86: Add support for initializing the APICRaul E Rangel
This is just the bare minimum required to initialize the APIC. I only support xAPIC and chose not to support x2APIC. We can add that functionality later when it's required. I also made the exception dispatcher call apic_eoi so that the callbacks won't forget to call it. BUG=b:109749762 TEST=Booted grunt and verified that depthcharge continued to function and that linux booted correctly. Also verified GDB still works.

2017-02-17libpayload: x86/main - propagate return value of main()Mathias Krause
According to coreboot’s payload API [1], the called payload should be able to return a value via %eax. Support this by changing the prototype of start_main() and pass on the return value of main() to the caller instead of discarding it.

2015-06-30libpayload: Make Kconfig bools use IS_ENABLED()Stefan Reinauer
This will make the code work with the different styles of Kconfig (emit unset bools vs don't emit unset bools) Roughly, the patch does this, and a little bit of fixing up: perl -pi -e 's,ifdef (CONFIG_LP_.+?)\b,if IS_ENABLED\($1\),g' `find . -name *.[ch]` perl -pi -e 's,ifndef (CONFIG_LP_.+?)\b,if !IS_ENABLED\($1\),g' `find . -name *.[ch]` Change-Id: Ib8a839b056a1f806a8597052e1b571ea3d18a79f Signed-off-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-on: http://review.coreboot.org/10711 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi@google.com>

This functionality is already available for ARM, so lets add it to x86 as well. We'll want to be able to hook exceptions when running as a remote GDB target.

2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.
