This updates the platform info HOB structure to align with the latest Ampere Altra Software Release Package (SRP) revision 2.10. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
This updates the NVPARAM definitions to align with the latest Ampere Altra Software Release Package (SRP) revision 2.10. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The current default setting of the hardware EINJ in the VFR is not consistent with the NVPARAM. And, the setting should be disabled by default. This is to correct the DEFAULT flag for the HW EINJ option in the VFR. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The existing DDR CE threshold feature is designed for both BMC and OS reporting. However, some customers wish to report exclusively to BMC while continuing to report all errors to the OS. The new NVPARAM "CE threshold control (THC)" has been introduced to address this scenario. THC = 0: Report to both BMC and OS. THC = 1: Report to both BMC. Default value is 0. If CE window is enabled and THC is set to 0, the DDR CE threshold option will be shown in the UEFI Setup Menu. Otherwise, the configuration option is hidden.

It is recommended that Symbol be used exclusively for x4 DIMMs. For non x4 DIMMs, it is advisable to select SECDED. This introduces an Auto mode in the ECC mode option, enabling automatic detection of the device width and selection of the recommended mode. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
To get rid of hardware dependency on a chosen RTC chip in the common SMpro/PMpro firmware, the SMpro will get the RTC datetime from UEFI through a mailbox interface instead of accessing directly to the platform RTC chip. This patch is to hook this date configuration to the runtime RTC library so the SMpro datetime is always updated once having changes from users both at boot time and runtime. Note that the CPU performance might be impacted with lack of this support. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
EDK2 firmware currently reports only the UEFI firmware booting stage and excludes the OS booting stage. The OS booting stage starts with the Boot Device Selection (BDS) phase and concludes with the Exit Boot Services event, as per the Ampere Altra SoC BMC Interface specification. Consequently, the endpoint for the UEFI firmware booting stage is designated as EFI_SW_DXE_CORE_PC_HANDOFF_TO_NEXT, and for the OS booting stage, it is EFI_SW_BS_PC_EXIT_BOOT_SERVICES.

This adds the LED device to the ACPI DSDT table to support the hotplug attention indicator control requested from Linux through ACPI. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
This patch is to initialize the UART2 designed for WinDbg. Also, drops the initialization of UART0 as it's been done in the Trusted Firmware-A (aka TF-A) for printing the early boot information. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The Ampere Altra processor has a unique MPIDR structure that accommodates the socket ID within the CPU core information. However, the existing GET_MPID() is incompatible, thus this patch introduces Ampere-specific MPIDR definitions. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
This patch updates the ARM_CORE_INFO.Mpidr to align with the new definition specific to Ampere. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
This patch updates the MPIDR entries in the MADT and SRAT ACPI tables to align with the MPIDR values produced in ARM_CORE_INFO. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
This patch is to advertise the ATS support in the Root Complex entries of the IORT table as Altra supports it. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The commit 32ac6cc ("JadePkg/AcpiTables: Update ACPI table of Altra for the new DSU PMU spec" has changed the DSU node path. This patch aims to rectify its path for _STAT patching. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The system is consistently configured to build 2-sockets memory map, irrespective of the slave's status, whether disabled or enabled. This configuration leads to a kernel crash when the slave is inactive. This patch aims to resolve this problem by properly patching the MMIO resource for 1P system. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
By default, ACPI DSDT defines the MMIO32 resource of RCs for 2P platform excluding RCA0/1 used for CCIX. For 1P platform, MMIO32 resource of other RCs should be modified but MMIO32 resource of RCA0/1 should be 256MB by default. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
The size of the allocated memory for the BERT Crash Dump is sizeof (APEI_CRASH_DUMP_BERT_ERROR), 0x27F8D. But, currently, the amount of memory copied to a specified location as defined ACPI BERT table is BERT_DDR_LENGTH (0x50000). This is more than the memory allocated. To fix this security hole, the memory copied should be the same as the memory allocated. Signed-off-by: Nhi Pham <nhi@os.amperecomputing.com>
BERT error record must be persistent across boots on catastrophic errors
until the BMC and UEFI have had a chance to retrieve the information. To
support this, the BERT is sectioned off into two different sections.
* BERT Error Record (sectors 0-61 => 4KB * 62 = 248KB)
* BERT Error Record Status (sectors 79 => 4KB * 1 = 4KB)
The BERT Error Record Status section will be updated, by UEFI, SCP
and BMC on the current state of the BERT Error Record.
The following parameters will keep the state of the BERT Error Record
* DefaultBert
Indicate Default Bert Error Record Present.
Set by UEFI on boot and cleared by SCP on shutdown, reboot,
or crash. If UEFI sees this parameter set it will populate
a default BERT to be reported to the OS.
* Overflow
The original BERT Error Record was over written by a subsequent
BERT Error Record. Set by SCP if PendingUefi or PendingBMC was
set and to be cleared by UEFI if PendingUefi and PendingBMC are
cleared.
* PendingUefi
Indicate Pending UEFI detection of BERT Error Record.
Set by SCP and to be cleared by UEFI. If parameter set
UEFI will populate the full BERT error record to be
reported to the OS.
* PendingBmc
Indicate Pending BMC detection of BERT Error Record.
Set by SCP and to be cleared by BMC.
The BERT Error Record can be read from the BMC via the following NVPARAM
addresses:
* 0x130000 - Read the beginning of BERT header
* 0x130030 - Read BERT Error Record revision
The BERT Error Record Status can be read from the BMC via the
following NVPARAM addresses:
* 0x17F000 - Read the beginning of AMPERE GUID
* 0x17F010 - Read BERT Error Record Status revision
* 0x17F018 - Read BERT Error Record Parameters
NVPARAM at 0x17f018: Param: 0x01010101
| | | `--DefaultBert
| | `----Overflow
| `------PendingUefi
`--------PendingBmc
To clear PendingBmc, set 0x00010101 to the Error Record Parameter
(0x17F018).

In the FailSafe context, there is a field that indicates which setting is being used to boot (BOOT_LAST_KNOWN_SETTINGS, BOOT_DEFAULT_SETTINGS, BOOT_NORMAL). On the SCP and TF-A side, they will check their NVPARAM for FailSafe (NV_SI_PMPRO_FAILURE_FAILSAFE - NV_SI_ATF_FAILURE_FAILSAFE) to determine which setting to use. If a FailSafe event occurs at SCP or TF-A, it is the responsibility of UEFI during the DXE phase to clear the FailSafe context to ensure normal behavior.

According to the SMBIOS specification, for multi-core processors, the cache size for the different levels of the cache (L1, L2, L3) is the total amount of cache per level per processor socket. The current ArmPkg/SMBIOS framework only constructs the cache size for a core. This patch aims to correct it. Additionally, this corrects the cache error correction type and cache configuration.
