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.

2020-12-22soc/intel/common/block/acpi: Fix get_cores_per_packagePatrick Rudolph
Current implementation uses CPUID 0Bh function that returns the number of logical cores of requested level. The problem with this approach is that this value doesn't change when HyperThreading is disabled (it's in the Intel docs), so it breaks generate_cpu_entries() because `numcpus` ends up being zero due to integer division truncation. - Use MSR 0x35 instead, which returns the correct number of logical processors with and without HT. - Use cpu_read_topology() to gather the required information Tested on Prodrive Hermes, the ACPI code is now generated even with HyperThreading disabled.

2020-12-04soc/intel/common/block/gpio: add code for NMI enablingMichael Niewöhner
Especially server boards, like the Supermicro X11SSM-F, often have a NMI button and NMI functionality that can be triggered via IPMI. The purpose of this is to cause the OS to create a system crashdump from a hang system or for debugging. Add code for enabling NMI interrupts on GPIOs configured with PAD_CFG_GPI_NMI. The enabling mechanism is the same as SMI, so the SMI function was copied and adapted. The `pad_community` struct gained two variables for the registers. Also register the NMI for LINT1 in the MADT in accordance to ACPI spec.

2020-06-06arch/x86: Declare permanent_smi_handler()Kyösti Mälkki
Advertising SMI triggers in FADT is only valid if we exit with SMI installed. There has been some experiments to delay SMM installation to OS, yet there are new platforms that allow some configuration access only to be done inside SMM. Splitting static HAVE_SMI_HANDLER variable helps to manage cases where SMM might be both installed and cleared prior to entering payload.

Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.

This is a Microsoft defined ACPI extension that allows an OS to know what the debug port is on a system when it is not enabled by the firmware, so it does not show up in the coreboot tables and cannot be easily found by a payload. broadwell: Use byte access device, set up only when enabled since it relies on the port being put in byte access mode and using this serial port for debug was not standard in this generation. skylake: Enable for the configured debug port. Skylake uses intelblocks for UART but not ACPI. common: Enable for the configured debug port. This affects apollolake and cannonlake. Tested by compiling for apollolake/broadwell, tested by reading the DBG2 ACPI table on kabylake board and using IASL to dump: [000h 0000 4] Signature : "DBG2" [004h 0004 4] Table Length : 00000061 [008h 0008 1] Revision : 00 [009h 0009 1] Checksum : 3B [00Ah 0010 6] Oem ID : "CORE " [010h 0016 8] Oem Table ID : "COREBOOT" [018h 0024 4] Oem Revision : 00000000 [01Ch 0028 4] Asl Compiler ID : "CORE" [020h 0032 4] Asl Compiler Revision : 00000000 [024h 0036 4] Info Offset : 0000002C [028h 0040 4] Info Count : 00000001 [02Ch 0044 1] Revision : 00 [02Dh 0045 2] Length : 0035 [02Fh 0047 1] Register Count : 01 [030h 0048 2] Namepath Length : 000F [032h 0050 2] Namepath Offset : 0026 [034h 0052 2] OEM Data Length : 0000 [036h 0054 2] OEM Data Offset : 0000 [038h 0056 2] Port Type : 8000 [03Ah 0058 2] Port Subtype : 0000 [03Ch 0060 2] Reserved : 0000 [03Eh 0062 2] Base Address Offset : 0016 [040h 0064 2] Address Size Offset : 0022 [042h 0066 12] Base Address Register : [Generic Address Structure] [042h 0066 1] Space ID : 00 [SystemMemory] [043h 0067 1] Bit Width : 00 [044h 0068 1] Bit Offset : 00 [045h 0069 1] Encoded Access Width : 03 [DWord Access:32] [046h 0070 8] Address : 00000000FE034000 [04Eh 0078 4] Address Size : 00001000 [052h 0082 15] Namepath : "\_SB.PCI0.UAR2" Change-Id: If34a3d2252896e0b0f762136760ab981afc12a2f Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/22453 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
2017-09-08soc/intel/common/block: Common ACPIShaunak Saha
This patch adds the common acpi code.ACPI code is very similar accross different intel chipsets.This patch is an effort to move those code in common place so that it can be shared accross different intel platforms instead of duplicating for each platform. We are removing the common acpi files in src/soc/intel/common. This removes the acpi.c file which was previously in src/soc/common/acpi. The config for common acpi is SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's Kconfig file in order to use the common ACPI code. This patch also includes the changes in APL platform to use the common ACPI block. TEST= Tested the patch as below: 1.Builds and system boots up with the patch. 2.Check all the ACPI tables are present in /sys/firmware/acpi/tables 3.Check SCI's are properly working as we are modifying the function to override madt. 4.Extract acpi tables like DSDT,APIC, FACP, FACS and decompile the by iasl and compare with good known tables. 5.Execute the extracted tables in aciexec to check acpi methods are working properly.
