Jeremy Jackson has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/42028 ) Change subject: The .config is overwritten when added to coreboot.rom via CBFS at the end of the build (if you choose that option)... should this be a separate file for each of fallback and normal? Since there can be two different versions and/or configurations, would fallback/config and normal/config make more sense? Also the "revision" file might benefit from similar treatment. ......................................................................

Change in coreboot[master]: WIP: Hash RAM contents on S3 entry and verify on S3 resume
by Raul Rangel (Code Review) 07 Aug '23

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/42890 ) Change subject: WIP: Hash RAM contents on S3 entry and verify on S3 resume ...................................................................... WIP: Hash RAM contents on S3 entry and verify on S3 resume I used murmur3 since it's supposed to be fast. Though I don't think the license is really compatible. The ram_hash code still needs some refactoring to reduce duplication and to add the ability to handle unaligned blocks. BUG=b:159081993 TEST=Boot trembyle and see no verification failures.

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/43301 ) Change subject: WIP: lib: Add murmur3 algorithm for RAM hash ...................................................................... WIP: lib: Add murmur3 algorithm for RAM hash This is the murmur3 algorithm from https://github.com/PeterScott/murmur3. I'm not sure we can even include this since it's public domain. We might need to use another hash algorithm. I picked it because it's supposed to be fast. I didn't cleanup the code at all. This is why -Wno-implicit-fallthrough was added to the CFLAGS. BUG=b:159081993 TEST=Suspend trembyle and see hashes being generated.

Change in coreboot[master]: soc/amd/picasso: Add support for RAM hash
by Raul Rangel (Code Review) 07 Aug '23

07 Aug '23

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/43302 ) Change subject: soc/amd/picasso: Add support for RAM hash ...................................................................... soc/amd/picasso: Add support for RAM hash This CL allocates a region in EARLY_DRAM to store the RAM hashes. It also introduces a hard coded memory map based on the current e820 map. In the future we could maybe automate the generate of the hash_ranges. Until now we will need to keep it updated. To enable, add the following to your .config: CONFIG_ENABLE_RAM_HASH=y Hashing RAM from the SMM handler is pretty slow compared to trying it in bootblock. Not sure if the OS has reset the MTRRs.

Change in ...coreboot[master]: [WIP]x86: Introduce the blobolator
by Patrick Rudolph (Code Review) 07 Aug '23

07 Aug '23

Patrick Rudolph has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/32020 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.
