2022-11-11acpi/acpi.c: Fix einj generation pointer arithmeticsJonathan Zhang
Without a cast the aritmetics of tat = einj + sizeof(acpi_einj_smi_t) is the same as tat = (uintptr_t)einj + size(acpi_einj_smi_t) * size(acpi_einj_smi_t) So it overshoots the intended offset by a lot. This issue only came apparent because now einj is in the small IMD region which is close to TSEG. With the wrong aritmetics the tat pointer ended up inside TSEG which is not accessible from the OS causing exceptions. TEST: observe that tat pointer is inside the small IMD below TSEG (0x78000000 on our setup).

This adds full EINJ support with trigger action tables. The actual error injection functionality is HW specific. Therefore, HW specific code should call acpi_create_einj with an address where action table resides. The default params of the action table are filled out by the common code. Control is then returned back to the caller to modify or override default parameters. If no changes are needed, caller can simply add the acpi table. At runtime, FW is responsible for filling out the action table with the proper entries. The action table memory is shared between FW and OS. This memory should be marked as reserved in E820 table. Tested on Deltalake mainboard. Boot to OS, load the EINJ driver ( modprobe EINJ) and verify EINJ memory entries are in /proc/iomem. Further tested by injecting errors via the APEI file nodes. More information on error injection can be referenced in the latest ACPI spec.

2021-01-11acpi,soc/intel/common: add support for Intel Low Power Idle TableMichael Niewöhner
Add support for the Intel LPIT table to support reading Low Power Idle Residency counters by the OS. On platforms supporting S0ix sleep states there can be two types of residencies: * CPU package PC10 residency counter (read from MSR via FFH interface) * PCH SLP_S0 assertion residency counter (read via memory mapped interface) With presence of one or both of these counters in the LPIT table, Linux dynamically adds the corresponding attributes to the cpuidle sysfs interface, that can be used to read the residency timers: * /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us * /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us The code in src/acpi implements generic LPIT support. Each SoC or platform has to implement `acpi_fill_lpit` to fill the table with platform-specific LPI state entries. This is done in this change for soc/intel/common, while being added as its own compilation unit, so SoCs not yet using common acpi code (like Skylake) can use it, too.

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-07-20src: Make HAVE_CF9_RESET set the FADT reset registerAngel Pons
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as reset register in FADT. How unsurprising. We might as well use that information to automatically fill in the FADT accordingly. So, do it. To avoid having x86-specific code under arch-agnostic `acpi/`, create a new optional `arch_fill_fadt` function, and override it for x86 systems. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-05-02acpi: Move ACPI table support out of arch/x86 (1/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 1/5 which moves .c files from arch/x86 to acpi/. The only acpi files that are still retained under arch/x86 are: a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there are some assumptions in there about SMM which will have to be resolved if this file needs to be moved to common code. b. acpi_bert_storage.c/bert_storage.h: This file is currently written specifically with x86 in mind. So, not moving the file for now. Motivation for this change: Not all stages on Picasso SoC are targeted for the same architecture. For example, verstage (if runs before bootblock) will be targeted for non-x86. This makes it difficult to add device tree to verstage which would be required to get to SoC configs from the tree. This is because the device tree on x86 platforms currently contains a lot of devices that require ACPI related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so on). Hence, this change removes all ACPI table support out of arch/x86.
