2023-04-26ACPI: Add COMMON_ACPI_MADT_IOAPIC and CUSTOM_ACPI_MADTKyösti Mälkki
Add Kconfig COMMON_ACPI_MADT_IOAPIC to replace platforms' implementations of adding IOAPIC and IRQ override entries for ACPI MADT tables. Platforms that have a more complex MADT may continue to add custom entries using CUSTOM_ACPI_MADT.

2023-04-26soc/intel: Introduce ioapic_get_sci_pin()Kyösti Mälkki
According to ACPI Release 6.5 systems supporting PIC (i8259) interrupt mechanism need to report IRQ vector for the SCI_INT field. In PIC mode only IRQ0..15 are allowed hardware vectors. This change should cover section 5.2.9 to not pass SCI_INT larger than IRQ15. Section 5.2.15.5 needs follow-up work. Care should be taken that ioapic_get_sci_pin() is called after platform code has potentially changed the routing from the default. It appears touched all platforms except siemens/mc_aplX currently program SCI as IRQ9.

This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e. Add multiple fan support for dptf policies. This also fixes the Google Meet resolution drop issue as per b:246535768 comment#12. When system starts Google Meet video call, it uses the hardware accelerated encoder as expected. But, as soon as another system connects to the call, an immediate fallback is observed from hardware to software encoder. Due to this, Google Meet resolution dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC based fanless platforms. This same issue was not seen on fan based systems. With the fix in dptf driver where fan configures appropriate setting for only fan participant, not for other device participants, able to see consistent 720p resolution. BUG=b:246535768,b:235254828 BRANCH=None TEST=Built and tested on Alder Lake-P Redrix system for two fans support and on Alder Lake-N fanless systems. With this code change Google Meet resolution drop not observed.

2023-01-28acpi/acpigen: factor out acpigen_write_processor_namestringFelix Held
This functionality is used in multiple places, so factor it out into a function. Compared to acpigen_write_processor_cnot, the buffer size is decreased from 40 to 16 bytes, but the format string specified by CONFIG_ACPI_CPU_STRING results in 9 chars and a NULL byte which will fit into the buffer without any issue. I've seen the CPU devices being put into another scope within \_SB, but even in that case that would be 14 chars and a NULL byte whist still fits into the 16 byte buffer. For acpigen_write_processor and acpigen_write_processor_package this doesn't change any edge case behavior. In the unrealistic case of the format string resulting in a longer CPU device string, this would have been a problem before this patch too. Also drop the curly braces of the for loop in acpigen_write_processor_package. This makes the code a bit harder to read and isn't a very good idea, but with the curly braces in place, the linter breaks the build :( Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I5d8291a2aaae2011cb185d72c7f7864b6e2220ec Reviewed-on: https://review.coreboot.org/c/coreboot/+/72452 Reviewed-by: Fred Reitberger <reitbergerfred@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Matt DeVillier <matt.devillier@amd.corp-partner.google.com> Reviewed-by: Elyes Haouas <ehaouas@noos.fr>

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 reverts commit 672bd9bee5c0045694ef20fe3e2f7a003bef0edd. Reason for revert: Gmeet resolution dropped. When system starts Gmeet video call, it uses the hardware accelerated encoder as per the expectation. But, as soon as another system connects to the call, the immediate fallback observed from hardware to software encoder. Due to this, Gmeet resolution dropped from 720p to 180p.

Another reason to do this is the following: On some platforms that start in dram it makes little sense to have separate stages.

To make this scheme more maintainable it makes sense to move out as much functionality from the 'main' function as possible.

The `find_resource` function will never return null (will die instead). In cases where the existing code already accounts for null pointers, it is better to use `probe_resource` instead, which returns a null pointer instead of dying.

2021-09-16acpi: Generate power resource name instead of default "PRIC"Furquan Shaikh
This change uses a static 8-bit counter in `acpi_device_add_power_res()` to generate the name of power resource object rather using a default name "PRIC". This makes it easier to identify which power resource Linux kernel logs are referring to. If more than 256 power resources are used in the system, then the counter will wrap around to 0. However, 256 seems to be a large enough number for the power resource count. TEST=Verified that Power Resources are named as expected: ``` dmesg | grep ACPI | grep PR [ 0.550921] ACPI: Power Resource [PR00] (on) [ 0.869960] ACPI: Power Resource [PR01] (on) [ 1.013973] ACPI: Power Resource [PR02] (on) ``` No new ACPI errors are seen in dmesg on brya.

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.
