Hello Arthur Heymans, Philipp Deppenwiese, build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/32020 to look at the new patch set (#2). Change subject: [WIP]x86: Introduce the blobolator ...................................................................... [WIP]x86: Introduce the blobolator This is a PoC to run arbitrary code and blobs inside an emulated virtual machine using libx86emu, thus the name blobolator. The libx86emu has been patched to the following: * redirect IO to the host machine it's running on * trace IO * start in protected mode * add mechanism to drop IO access * add Kconfig to debug code it is running Implemented features: * Run ramstage in libx86emu * Run postcar in libx86emu TODO: * Add support to trace only blobs, not stages. * Improve translation of known IO to human readable format ** COM ** PCI ** APIC ** PIT ** POST Tested on qemu. Sucessfully run ramstage in blobolator.
