ShellPkg/AcpiView: Add parser for CCEL ACPI table

2026-07-03T12:24:39+00:00

The ACPI 6.5 specification introduces the CCEL (CC Event Log) table in section 5.2.34: https://uefi.org/specs/ACPI/6.5/ 05_ACPI_Software_Programming_Model.html#cc-event-log-acpi-table Extend AcpiView with a parser to decode and display CCEL table contents. This allows users to inspect CCEL tables from the UEFI Shell. Signed-off-by: Sami Mujawar

ShellPkg/Acpiview: Make reserved-field validation common

2026-07-03T12:24:39+00:00

Move the reserved-field validators from MpamParser.c into AcpiParser.c and expose them through AcpiParser.h so they can be reused by multiple Acpiview parsers. Update the AGDI, MPAM and WSMT parsers to use the common helpers for byte-length and bit-length reserved fields. Signed-off-by: Sami Mujawar

ShellPkg/Acpiview: Increase the max supported parsers

2026-07-03T12:24:39+00:00

The RegisterParser() function is failing with error code EFI_OUT_OF_RESOURCES as we have run out of space for registering the ACPI table parsers in mTableParserList[]. Therefore, increase the MAX_ACPI_TABLE_PARSERS to 128. Signed-off-by: Sami Mujawar

ShellPkg: Add missing smbiosview Type 28 locations

2026-07-02T07:22:54+00:00

Add the missing SMBIOS Type 28 Temperature Probe location decode values to smbiosview. The Type 28 Location field defines values 0x0C through 0x0F for Front Panel Board, Back Panel Board, Power System Board, and Drive Back Plane, but smbiosview only decoded values up to 0x0B.

ShellPkg: Fix smbiosview Type 26 location/status decode

2026-07-02T07:22:54+00:00

The smbiosview Type 26 Voltage Probe decoder uses the low 5 bits of LocationAndStatus as the probe location and the high 3 bits as the probe status. However, the Type 26 lookup tables were swapped: VPLocationTable contained status strings and VPStatusTable contained location strings. This caused valid records to be displayed as, for example: Voltage Probe - Location: OK Voltage Probe - Status: Processor Swap the table contents so Type 26 output matches the SMBIOS LocationAndStatus bit layout.

ShellPkg: Add null pointer checks before dereference

2026-07-01T12:10:28+00:00

In AllocateMemory(), several pointers are used without prior null checks. This may lead to unexpected behavior or system crashes if any of these pointers are NULL. Add explicit null checks for these pointers to ensure safe access and prevent potential null pointer dereferences. Signed-off-by: Qihang Gao

ShellPkg: ShellPkg: Fix SMBIOS Type 28 probe labels

2026-06-29T17:19:33+00:00

Use a Temperature Probe specific HII string when displaying the Type 28 Location field in smbiosview. The Type 28 decoder was using the Voltage Probe location label, causing temperature probe records to be displayed with the wrong field name. Signed-off-by: Varshit Pandya

ShellPkg: Fix SMBIOS Type 26 probe decoding

2026-06-29T17:19:33+00:00

Decode the Type 26 Voltage Probe Location and Status fields according to the SMBIOS 3.9.0 specification, section 7.27, "Voltage Probe (Type 26)". Table 95, "Voltage Probe: Location and Status fields", defines bits 4:0 as the Location field and bits 7:5 as the Status field. smbiosview was decoding these fields in the opposite order, causing the displayed voltage probe location and status to be swapped.

ShellPkg: Fix the issue that the UEFI Shell layout is messed up

2026-06-21T16:49:02+00:00

Fixes https://github.com/tianocore/edk2/issues/12689 When the UEFI Shell mapping table is empty (NULL), the console layout becomes corrupted in DEBUG builds. This occurs because the cursor position for the message map: No mapping found. is computed incorrectly under DEBUG mode. The presence of DEBUG output from the Shell driver causes gST->ConOut->Mode->CursorRow to no longer reflect the actual cursor position on the serial port, leading to misplacement of subsequent output. This patch replaces the existing print routine with ShellPrintHiiDefaultEx(). The new function automatically calculates the correct cursor position for the "No mapping found" line, eliminating the dependency on the stale CursorRow value. As a result, the layout remains consistent regardless of DEBUG message activity. Signed-off-by: Qihang Gao
