[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.

I couldn't find the original x86emu any more. It looks like libx86emu is the successor to x86emu.

I couldn't find the original x86emu any more. It looks like libx86emu is the successor to x86emu.
The original is somewhere deep in the XFree86 (and likely Xorg) tree. We can use libx86emu, but we shouldn't keep two copies in our tree is all I'm saying.

Patch Set 2:
coreboot's version of x86emu has been significantly refactored for code size. It would be interesting to upstream these changes, albeit that's a lot of work as the original diffs have not been preserved (LinuxBIOS v1 timeframe, and only the final refactored product was posted back then)
- Please do not add a second copy of x86emu to the tree. - If we decide that this copy should replace the size optimized version, please make sure you test with yabel and the native bios emulation on a fair number of option roms to not break the existing code.

[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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).

Hello Julius Werner, Angel Pons, Arthur Heymans, Daniel Maslowski, Christian Walter, Felix Singer, 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 (#8).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).

Hello Julius Werner, Angel Pons, Arthur Heymans, Daniel Maslowski, Christian Walter, Felix Singer, 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 (#9).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing * Added test code in qemu emulation/q35
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).

Hello Julius Werner, Angel Pons, Arthur Heymans, Daniel Maslowski, Christian Walter, Felix Singer, 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 (#10).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing * Added test code in qemu emulation/q35 * Machine parseable format
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).
You need to install 3rdparty/libx86emu from https://github.com/PatrickRudolph/libx86emu/tree/cpuid_msr_callback

Hello Julius Werner, Arthur Heymans, Daniel Maslowski, Christian Walter, Felix Singer, 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 (#12).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing * Added test code in qemu emulation/q35 * Machine parseable format
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).
You need to install 3rdparty/libx86emu from https://github.com/PatrickRudolph/libx86emu/tree/cpuid_msr_callback

Hello Julius Werner, Arthur Heymans, Daniel Maslowski, Christian Walter, Felix Singer, 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 (#13).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing * Added test code in qemu emulation/q35 * Machine parseable format
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).
You need to install 3rdparty/libx86emu from https://github.com/PatrickRudolph/libx86emu/tree/cpuid_msr_callback

Hello Felix Singer, Philipp Deppenwiese, build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Daniel Maslowski, Christian Walter, Julius Werner, Arthur Heymans, Patrick Rudolph,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/32020
to look at the new patch set (#14).
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 * Kconfig specific hooks by using _blobolator_drivers (same mechanism as __pci_driver) * PCI decoding and BAR tracing * POST code decoding * Unhandled IO tracing * Added test code in qemu emulation/q35 * Machine parseable format
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. Tested on X11SSH-TF. Sucessfully run ramstage in blobolator (requires additional libx86emu patches).
You need to install 3rdparty/libx86emu from https://github.com/PatrickRudolph/libx86emu/tree/cpuid_msr_callback
