* DynamicTablesPkg: Exempt some _CPC field from checksPierre Gondois2024-01-292-4/+27
| | | | | | | | | | | | | | | | | | | | | When generating _CPC objects, some fields are mandatory by spec [1]. Some fields cannot be supported by a the Juno platform, which is used to test the _CPC generation. Therefore, rely on the PcdDevelopmentPlatformRelaxations Pcd to either: - warn about the missing fields and and let the OS handle the missing information - consider the missing fields as an error _CPC fields that are exempted from checks when the Pcd is set: - PerformanceLimitedRegister - ReferencePerformanceCounterRegister - DeliveredPerformanceCounterRegister [1] Cf. non-optional fields in: ACPI 6.5, s8.4.6.1 '_CPC (Continuous Performance Control)' Signed-off-by: Pierre Gondois <pierre.gondois@arm.com> Reviewed-by: Sami Mujawar <sami.mujawar@arm.com>

| | | | | | | | | | | | Some development platforms might not be compliant on some points of some specifications. In order to have a generic code accurately checking against specifications while still allowing some relaxation on specific points for the platforms that desire it, add a Pcd acting as a bitfield to warn instead of returning an error in case of non-compliance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Coresight Embedded Trace Extension (ETE) feature can be detected by the platform firmware by examining the debug feature register ID_AA64DFR0_EL1.TraceVer field. The platform configuration manager can then describe the ETE by creating CM_ARM_ET_INFO object(s) and referencing these in CM_ARM_GICC_INFO.EtToken. The 'Table 3: Compatible IDs for architected CoreSight components' in the 'ACPI for CoreSight 1.2 Platform Design Document' specifies the HID value for Coresight ETE and CoreSight Embedded Trace Macrocell (ETM) v4.x as ARMH C500. Therefore, update the SsdtCpuTopologyGenerator to add an ETE device to the CPU node in the AML CPU hierarchy so that an OS can utilise this information. Note: Although ETE and ETM share the same HID, ETE has a system register interfaces, unlike ETM which requires memory mapped registers. Since this patch aims to support ETE, the AML description does not describe any memory mapped registers. However, support for ETM can be added in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes two bugs and adds some enhancements to the handling of characters and strings in objects being printed by the CM ObjectParser. Bug fixes: 1. PrintOemID() currently attempts to print characters with "%C", but the correct syntax is (lowercase) "%c". This bug results in "CCCCCC" being printed instead of the actual ASCII characters. 2. PrintString() is being passed a pointer to data in objects, but in some cases this data is the actual string to print and other cases it is a pointer to the string to print. This adds a PrintStringPtr function and uses the correct functions depending on the situation. Enhancements: 1. Some objects contain ASCII characters, which are currently printed as their hex values. This adds functions to print out ASCII character fields as text rather than hex, and uses those functions in several cases where the object data is defined to be ASCII. 2. The PrintOemID() function is replaced with the new identical but more generecically-named PrintChar6() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The topology of a platform is represented in ACPI using the PPTT table. It is possible to append information to CPUs/processor containers using their associated AML nodes in a SSDT table. A platform might have multiple 'physical packages' (or top-level nodes) in their PPTT topology representation. It can be assumed from [1] that a 'physical packages' is always a 'top-level node', and conversely. The SSDT topology generator doesn't support having multiple top-level nodes. The top-level node is also not generated in the SSDT topology representation. Add support to generate multiple top-level nodes in the SSDT topology generator and generate an AML node for this top-level node. This will allow to have matching PPTT and SSDT topology representations. Prior to this patch, this top-level AML node was not generated. Also factorize the flag checking in CheckProcNode() and add more checks. This patch takes inspiration from the discussion at: - v1: https://edk2.groups.io/g/devel/message/99410 - v2: https://edk2.groups.io/g/devel/message/99615 [1] ACPI 6.5, 5.2.30.1 Processor hierarchy node structure (Type 0): - "Multiple trees may be described, covering for example multiple packages. For the root of a tree, the parent pointer should be 0."" - "Each valid processor must belong to exactly one package.

Text strings are added at the end of the formatted portion of the SMBIOS structure and are referenced by index in the SMBIOS structure. Therefore, introduce a SmbiosStringTableLib to simplify the publishing of the string set. SmbiosStringTableLib introduces a concept of string table which records the references to the SMBIOS strings as they are added and returns an string reference which is then assigned to the string field in the formatted portion of the SMBIOS structure. Once all strings are added, the library provides an interface to get the required size for the string set. This allows sufficient memory to be allocated for the SMBIOS table. The library also provides an interface to publish the string set in accordance with the SMBIOS specification. Example: EFI_STATUS BuildSmbiosType17Table () { STRING_TABLE StrTable; UINT8 DevLocatorRef; UINT8 BankLocatorRef; SMBIOS_TABLE_TYPE17 *SmbiosRecord; CHAR8 *StringSet; ... // Initialize string table for 7 strings StringTableInitialize (&StrTable, 7); StringTableAddString (&StrTable, "SIMM 3", &DevLocatorRef); StringTableAddString (&StrTable, "Bank 0", &BankLocatorRef); ...

SmbiosRecord->DeviceLocator = DevLocatorRef; SmbiosRecord->BankLocator = BankLocatorRef; ... // get the string set area StringSet = (CHAR8*)(SmbiosRecord + 1); // publish the string set StringTablePublishStringSet ( &StrTable, StringSet, StringTableGetStringSetSize (&StrTable) ); // free string table StringTableFree (&StrTable); return EFI_SUCCESS; } Signed-off-by: Sami Mujawar <sami.mujawar@arm.com> Reviewed-by: Pierre Gondois <pierre.gondois@arm.com> Cc: Alexei Fedorov <Alexei.Fedorov@arm.com> Cc: Pierre Gondois <pierre.gondois@arm.com> Cc: Girish Mahadevan <gmahadevan@nvidia.com> Cc: Jeff Brasen <jbrasen@nvidia.com> Cc: Ashish Singhal <ashishsingha@nvidia.com> Cc: Nick Ramirez <nramirez@nvidia.com> Cc: William Watson <wwatson@nvidia.com> Cc: Samer El-Haj-Mahmoud <Samer.El-Haj-Mahmoud@arm.com>

* DynamicTablesPkg: Allow for specified CPU namesJeff Brasen2022-12-193-11/+43
| | | | | | | | | | | | | | | Allow object to specify the name of processor and processor container nodes and the UID of processor containers. This allows these to be more accurately referenced from other tables. For example for the _PSL method or the UID in the APMT table. The UID and Name for processor container may be different as if the intention is to set names as the corresponding affinity level the UID may need to be different if there are multiple levels of containers.
