Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/36126 ) Change subject: Documentation: Add cache as ram documentation ...................................................................... Documentation: Add cache as ram documentation This add documentation around coreboot's history of CAR usage. The history is reconstructed from articles and git/svn history, but should provide a good overview of the challenges and solutions coreboot came up with to deal with early code execution on X86 platforms. The technical details about CAr will come in follow-up patch and are marked as TODO for now.

Not only do they start in 16bit 'real' mode, +most of the hardware starts uninitialized. This includes the dram +controller. Another thing about X86 platforms is that they generally +don't feature SRAM, static RAM. SRAM for this purpose of this text is +a small region of ram that is available without any initialization. +Without RAM this leaves the system with just CPU registers and a +memory mapped boot medium of which code can be executed in place (XIP) +to initialize the hardware. + +For simple dram controllers that environment is just fine and +initializing the dram controller in assembly code without using a +stack is very doable. Modern systems however require complex +initialization procedures and writing that in assembly would be either +too hard or simply impossible. To overcome this limitation a technique +called Cache-as-Ram exists. It allows to use the CPU's Cache-as-Ram. +This in turn makes it possible to write the early initialization code +in a higher level programming language compiled by a regular compiler, +e.g. GCC. Typically only the stack is placed in Cache-as-Ram and the +code is still executed in place, but copying code in the cache as ram +and executing from there is also possible. + +For coreboot this means that with only a very small amount of assembly +code to set up CAR, all the other code can written in C, which +compared to writing assembly tremendously increases development speed +and is much less error prone. + +## A bit of history on Cache-as-Ram in coreboot + +### Linux as a BIOS? The invention of romstage + +When LinuxBIOS, later coreboot, started out, the first naive attempt +to run the Linux kernel instead of the legacy BIOS interface, was to +jump straight to loading the kernel. This did not work at all, since +dram was not working at that point. LinuxBIOS v1 therefore +initialized the memory in assembly before it was able to load the +kernel. This executed in place and would later become romstage. It +turned that Linux needed other devices, like enumerated and have it's +resources allocated, so yet another stage, ramstage, was called into +life, but that's another story. + +### coreboot v2: romcc + +In 2003 AMD's K8 CPU's came out. Those CPU's featured an on die memory +controller and also a new point to point BUS for CPU <-> CPU and +CPU <-> IO controller (northbridge) devices. Writing support for +these in assembly became difficult and a better solution was needed. +This is where ROMCC came to the rescue in 2002. ROMCC is a 25K lines +of code C compiler, written by Eric Biederman, that does not use a +stack but uses CPU registers instead. Besides the 8 general purpose +registers on x86 the MMX and SSE registers, respectively _%mm0_-_%mm7_ +and _%xmm0_-_%xmm7_, can be used to store data. ROMCC also converts +all function calls to static inline functions. This has the +disadvantage that a ROMCC compiled stage must be compiled in one go, +linking is not possible. In practice you will see a lot of '#include +_some_file.c_' which is quite unusual in C, because it makes the +inclusion of files fragile. Given that limited amount +'register-stack', it also imposes restrictions on how many levels of +nested function can be achieved. One last issue with ROMCC is that +no-one really dared touching that code, due to its size and complexity +besides its original author. + +Coreboot used ROMCC in the following way: a bootblock written in both +assembly to enter 32bit protected mode would use ROMCC compiled code +to either jump to 'normal/romstage' or 'fallback/romstage' which in +turn was also compiled with romstage. + +### Cache-as-Ram + +While ROMCC was eventually used for early initialization, prior to +that development attempts were made to use the CPU's cache as RAM. +This would allow to use regular GCC compiled and linked code to +be used. The idea is to set up the CPU's cache to Write Back to a +region, while disable cacheline filling or simply hope that no cache +eviction or invalidation happens. Eric Biederman initially got CAR +working, but with the advent of Intel Hyperthreading on the Pentium 4, +on which CAR setup proved to be a little more difficult and he +developed ROMCC instead. + +Around 2006 a lot was learned from coreboot v2 with its ROMCC usage +and development on coreboot v3 was started. The decision was mode to +not use ROMCC anymore and use Cache Memory for early stages. The +results were good as init object code size is reduced by factor of +four. So the code was smaller and faster at the same time. + +coreboot v4 sort of merged v2 and v3, so it was a mix of ROMCC compiled +romstage and romstage with CAR. + +In 2014 Support for ROMCC compiled romstage was dropped. + +### Intel Apollolake, a new era: POSTCAR_STAGE and C_ENVIRONMENT_BOOTBLOCK + +In 2016 Intel released the ApolloLake architecture. This architecture +is a weird duck in the X86 pool. It is the first Intel CPU to feature +MMC as a boot medium and does not memory map it. It also features to +the main CPU read only SRAM that is mapped right below 4G. The +bootblock is copied to SRAM and executed. Given that the boot medium +is not always memory mapped XIP is not an option. The solution is to +set up CAR in the bootblock and copy the romstage in CAR. We call this +C_ENVIRONMENT_BOOTBLOCK, because it runs GCC compiled code. Granted +XIP is still possible on ApolloLake, but coreboot has to use Intel's +blob, FSP-M, and it is linked to run in CAR, so a blob actually forced +a nice feature in coreboot! + +Another issue arises with this setup. With romstage running from the +read only boot medium, you can continue executing code (albeit without +stack) to tear down the CAR and start executing code from 'real' RAM. +On ApolloLake with romstage executing from CAR, tearing down CAR in +there, would shooting in ones own foot, as our code would be gone +in doing so. The solution was to tear down CAR in a separate stage, +named 'postcar' stage. This provides a clean separation of programs +and results in needing less linker scripts hacks in romstage. This +solution was therefore adopted by many other platforms that still did +XIP. + +### AMD Zen, 2019 + +On AMD Zen the first CPU to come out of reset is the PSP and it +initializes the dram before pulling out the main CPU out of reset. +CAR won't be needed, nor used on this platform. + +### The future? + +For coreboot release 4.11, scheduled for october 2019, support for +ROMCC in the bootblock will be dropped as will support for the messy +tearing down of CAR in romstage as opposed to doing that in a separate +stage. + +## In depth analysis + +### CAR setup + +TODO: MTRR, IPI/hyperthreaded, ROM Caching, Non-evict + +### Linker symbols + +TODO: sharing things over multiple CAR stages: car.ld + +### CAR teardown + +TODO: postcarstage, NO_CAR_GLOBAL_MIGRATION + +## References +[2007, The Open Source BIOS is Ten An interview with the coreboot developers](http://www.h-online.com/open/features/The-Open-Source-BIOS-is-T… +[A Framework for Using Processor Cache-as-Ram (CAR)](https://www.coreboot.org/images/6/6c/LBCar.pdf) +[CAR: Using Cache-as-Ram in LinuxBIOS](https://www.coreboot.org/data/yhlu/cache_as_ram_lb_09142006.pdf) diff --git a/Documentation/index.md b/Documentation/index.md index 1c04ad3..85666cb 100644 --- a/Documentation/index.md +++ b/Documentation/index.md @@ -177,6 +177,7 @@ * [Display panel-specific documentation](gfx/display-panel.md) * [Architecture-specific documentation](arch/index.md) * [Platform independend drivers documentation](drivers/index.md) +* [CPU-specific documentation](cpu/index.md) * [Northbridge-specific documentation](northbridge/index.md) * [System on Chip-specific documentation](soc/index.md) * [Mainboard-specific documentation](mainboard/index.md) -- To view, visit https://review.coreboot.org/c/coreboot/+/36126 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I964d59a6bd210f3d4d06220d2ec7166110ab2cf3 Gerrit-Change-Number: 36126 Gerrit-PatchSet: 1 Gerrit-Owner: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-MessageType: newchange

Change in coreboot[master]: eltan/verified_boot: include vboot21 code directly
by Joel Kitching (Code Review) 07 Aug '23

07 Aug '23

Joel Kitching has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37654 ) Change subject: eltan/verified_boot: include vboot21 code directly ...................................................................... eltan/verified_boot: include vboot21 code directly vboot 2.1 data structures and code, as well as the fwlib21 build target, are all being deprecated. Any use of these data structures and code should be forked and handled separately. The data structures and functions used by eltan verified boot were never part of the vboot API, and were never intended to be used by external parties. Instead of building fwlib21 target, build fwlib instead, which will be the only available library going forward. This can provide access to the vb2_sha.h API. Note that vboot 2.1 error codes will also be deprecated in the future. At this point, vb2_error_t may also be forked and included in eltan_vb21.h.

Change in coreboot[master]: soc/intel/common/systemagent: Add SOC_INTEL_COMMON_BLOCK_SA_VERSION_2
by Subrata Banik (Code Review) 07 Aug '23

07 Aug '23

Subrata Banik has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/38456 ) Change subject: soc/intel/common/systemagent: Add SOC_INTEL_COMMON_BLOCK_SA_VERSION_2 ...................................................................... soc/intel/common/systemagent: Add SOC_INTEL_COMMON_BLOCK_SA_VERSION_2 System Agent (SA) register 0x60:PCIEXBAR register LENGTH offset definition has been changed for newer SoC. This change provides a new Kconfig option that can be selected by SoCs using these new bit definitions of LENGTH. Common code takes care of setting the right value for pciex length depending upon the version selected by SOC.
