2023-12-20acpi: Reduce wait interval in delay loop for sleepSukumar Ghorai
The optimization of sleep time in acpi code includes reducing the sleep duration and increasing the polling frequency within the acpi _ON/_OFF method. StorageD3Enable is activated in Google/Rex, and this optimization results in a saving of approximately 25ms in D3cold resume time, reducing it from around 160ms to 135ms.

2023-12-15acpi: Add support for WDAT tableMarek Maslanka
This commit lays the groundwork for implementing the ACPI WDAT (Watchdog Action Table) table specification. The WDAT is a special ACPI table introduced by Microsoft that describes the watchdog for the OS. Platforms that need to implement the WDAT table must describe the hardware watchdog management operations as described in the specification. See “Links to ACPI-Related Documents” (http://uefi.org/acpi) under the heading “Watchdog Action Table”. BUG=b:314260167 TEST=Mock the acpi_soc_fill_wdat function for a specific platform/soc and enable ACPI_WDAT_WDT in the kconfig. Check if the build passes successfully.

2023-12-02acpi: Add PPTT supportDavid Milosevic
This patch adds code to generate Processor Properties Topology Tables (PPTT) compliant to the ACPI 6.4 specification. - The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT is selected. Its purpose is to return a pointer to a topology tree, which describes the relationship between CPUs and caches. The hook can be provided by, for example, mainboard code. Background: We are currently working on mainboard code for qemu-sbsa and Neoverse N2. Both require a valid PPTT table. Patch was tested against the qemu-sbsa board.

2023-11-15acpi/acpigen: rework acpigen_pop_len for different size PkgLengthFelix Held
Previously acpigen_pop_len always wrote a 3 byte PkgLength to the 3 bytes reserved by acpigen_write_len_f. After this patch acpigen_pop_len encodes PkgLength in 1-3 bytes depending on the PkgLength. When less than the 3 bytes that were previously reserved in the corresponding acpigen_write_len_f call are needed for PkgLength, the payload data will be moved back by the number of reserved bytes that aren't needed for the PkgLength. This fixes the problem that the Windows AML parser doesn't like a 3 byte PkgLength being used for the size of the buffer containing UTF-16 strings when the length could be encoded in a single PkgLength byte. In that case, Windows previously ignored the whole SSDT containing this larger than necessary PkgLength encoding. It should however be noted that the ACPI 6.4 spec doesn't specify if it's required to always use the most compact possible encoding of the PkgLength or not. Since iasl generates the shortest possible PkgLength encoding, it's also a good idea to make coreboot's acpigen do the same although it's not required by the specification. With this patch applied, Windows still boots on Mandolin and the time it takes to write the tables doesn't change. To measure the times, the log level in bs_sample_time was increased to BIOS_CRIT and the console log level was increased to BIOS_CRIT too to only get those times as output.

2023-09-13acpi/soundwire.[ch]: Fix dpn entry array overrunMartin Roth
In soundwire.h, SOUNDWIRE_DPN MIN & MAX are set to 1 and 14. When creating the dpn array, the length was set to MAX - MIN or 13, numbered 0 to 12. When accessing the array, the code was bailing out if a value greater than MAX was trying to be accessed, so the array was able to be overrun by two structure lengths. Fix this problem by: 1) Not subtracting the MIN value when creating the array, which does waste a little space. If anyone wants to refactor the code to fix that, please feel free. 2) Breaking out of the loop when the port is equal to the MAX port number instead of just when it's greater than the max port number.

2023-08-03acpi.c: Swap XSDT and RSDT for adding/finding tablesArthur Heymans
If ACPI is above 4G it's not possible to have a valid RSDT pointer in RSDP, therefore swap RSDT and XSDT. Both are always generated on x86. On other architectures RSDT is often skipped, e.g. aarch64. On top of that the OS looks at XSDT first. So unconditionally using XSDT and not RSDT is fine. This also deal with the ACPI pointer being above 4G. This currently never happens with x86 platforms.

2023-07-20acpi: Move ECAM resource below PNP0C02 device in a common placeArthur Heymans
From the Linux documentation (Documentation/PCI/acpi-info.rst): [6] PCI Firmware 3.2, sec 4.1.2: If the operating system does not natively comprehend reserving the MMCFG region, the MMCFG region must be reserved by firmware. The address range reported in the MCFG table or by _CBA method (see Section 4.1.3) must be reserved by declaring a motherboard resource. For most systems, the motherboard resource would appear at the root of the ACPI namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and the resources in this case should not be claimed in the root PCI bus’s _CRS. The resources can optionally be returned in Int15 E820 or EFIGetMemoryMap as reserved memory but must always be reported through ACPI as a motherboard resource. So in order for the OS to use ECAM MMCONF over legacy PCI IO configuration, a PNP0C02 HID device needs to reserve this region. As no AMD platform has this defined in DSDT this fixes Linux using legacy PCI IO configuration over MMCONF. Tianocore messes with e820 table in such a way that it prevents Linux from using PCIe ECAM. This change fixes that problem.

In ACPI 1.0 the processor objects were inside the \_PR scope, but since ACPI 2.0 the \_SB scope can be used for that. Outside of coreboot some firmwares still used the \_PR scope for a while for legacy ACPI 1.0 OS compatibility, but apart from that the \_PR scope is deprecated. coreboot already uses the \_SB scope for the processor devices everywhere, so move the \_SB scope out of the ACPI_CPU_STRING to the format string inside the 3 snprintf statements that use the ACPI_CPU_STRING.

This issue is observed on Alder Lake-N SoC based fanless platforms. This same issue was not seen on fan based systems.

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>
