Kyösti Mälkki 4bd9187dad ACPI: Refactor use of global and device NVS
After ChromeOS NVS was moved to a separate allocation and the use
of multiple OperationRegions, maintaining the fixed offsets is not
necessary.

Use actual structure size for OperationRegions, but align the
allocations to 8 bytes or sizeof(uint64_t).

Felix Held f7dbf4afd6 acpi: drop weak implementation of acpi_soc_get_bert_region
acpi_soc_get_bert_region only gets called when a chipset's Kconfig
selects the ACPI_BERT option in which case the chipset code needs to
implement this function. In the case of acpi_soc_get_bert_region not
being implemented, but ACPI_BERT being selected for a chipset this patch
changes the behavior from never generating a BERT ACPI table to a build
error which is more obvious and easier to catch.

Felix Held fba479267b acpi: rework BERT ACPI table generation logic
Check if the ACPI_BERT Kconfig option is selected and only then try to
generate the BERT table. Also remove the acpi_is_boot_error_src_present
weak function from the ACPI global compilation unit and use the return
value of acpi_soc_get_bert_region to determine if there is a valid BERT
region with logged errors.

Rocky Phagura eff0713dfc src/acpi: Add APEI EINJ support
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.

Until now every AML package had to be closed using acpigen_pop_len().
This commit introduces set of package closing functions corresponding
with their opening function names. For example acpigen_write_if()
opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.

Kyösti Mälkki ae7ac8a723 ACPI: Separate ChromeOS NVS in ASL
For builds with MAINBOARD_HAS_CHROMEOS=y but CHROMEOS=n, there
is reduced dsdt.aml size and reduced GNVS allocation from cbmem.

More importantly, it's less error-prone when the OperationRegion
size is not hard-coded inside the .asl files.

Kyösti Mälkki cf246d5166 ACPI: Add top-level ASL
Objects that are created with acpigen need to be declared
with External () for the generation of dsdt.asl to pass
iasl without errors.

There are some objects that are common to all platforms,
and some that should be declared only conditionally.
Having a top-level ASL helps to achieve this.

array for chromeos_acpi_t. This allows us to reduce

If chromeos_acpi_t was the last entry in struct global_nvs
padding at the end is also removed.

If device_nvs_t exists, place a properly sized reserve for
chromeos_acpi_t in the middle.

Allocation from cbmem is adjusted such that it matches exactly
the OperationRegion size defined inside the ASL.

Michael Niewöhner f0a44ae0eb acpi,soc/intel/common: add support for Intel Low Power Idle Table
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.

Reference:
https://uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf

Test: Linux adds the cpuidle sysfs interface; Windows with s0ix_enable=1
      boots without crashing with an INTERNAL_POWER_ERROR.

- Windows and Linux tested on google/akemi together with CB:49046
- Linux tested on clevo/cml-u, supermicro/x11ssmf together with CB:49046
