[PATCH] Linux-specific header: Add support for s390x compilation
by Colin King
From: Colin Ian King <colin.king(a)canonical.com>
While porting ACPCIA integrated into fwts I discovered that I get build
issues on s390x because ACPCIA does not know it is a 64 bit architecture.
Update aclinux.h to support this architecture.

Question about the code in source/components/hardware/hwxfsleep.c
by Kein Yuan
Hi ACPICA experts, A quick question,
File: source/components/hardware/hwxfsleep.cFunction: AcpiHwSetFirmwareWakingVector
static ACPI_STATUSAcpiHwSetFirmwareWakingVector ( ACPI_TABLE_FACS *Facs, ACPI_PHYSICAL_ADDRESS PhysicalAddress, ACPI_PHYSICAL_ADDRESS PhysicalAddress64){ ACPI_FUNCTION_TRACE (AcpiHwSetFirmwareWakingVector);
/* * According to the ACPI specification 2.0c and later, the 64-bit * waking vector should be cleared and the 32-bit waking vector should * be used, unless we want the wake-up code to be called by the BIOS in * Protected Mode. Some systems (for example HP dv5-1004nr) are known * to fail to resume if the 64-bit vector is used. */
/* Set the 32-bit vector */
Facs->FirmwareWakingVector = (UINT32) PhysicalAddress;
if (Facs->Length > 32) // ---------------------> Question for this compare { if (Facs->Version >= 1) { /* Set the 64-bit vector */
Facs->XFirmwareWakingVector = PhysicalAddress64; } else { /* Clear the 64-bit vector if it exists */
Facs->XFirmwareWakingVector = 0; } }
return_ACPI_STATUS (AE_OK);}
Since the FACS structure defined as:typedef struct acpi_table_facs{ char Signature[4]; /* ASCII table signature */ UINT32 Length; /* Length of structure, in bytes */ UINT32 HardwareSignature; /* Hardware configuration signature */ UINT32 FirmwareWakingVector; /* 32-bit physical address of the Firmware Waking Vector */ UINT32 GlobalLock; /* Global Lock for shared hardware resources */ UINT32 Flags; UINT64 XFirmwareWakingVector; /* 64-bit version of the Firmware Waking Vector (ACPI 2.0+) */ UINT8 Version; /* Version of this table (ACPI 2.0+) */ UINT8 Reserved[3]; /* Reserved, must be zero */ UINT32 OspmFlags; /* Flags to be set by OSPM (ACPI 4.0) */ UINT8 Reserved1[24]; /* Reserved, must be zero */
} ACPI_TABLE_FACS;
May I know in what case Facs->Length < 32?
If looks to me that Facs->XFirmwareWakingVector = PhysicalAddress64; will always be executed?
Thanks,Kein

ACPICA version 20161117 released
by Moore, Robert
17 November 2016. Summary of changes for version 20161117:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Table Manager: Fixed a regression introduced in 20160729, "FADT support cleanup". This was an attempt to remove all references in the source to the FADT version 2, which never was a legal version number. It was skipped because it was an early version of 64-bit support that was eventually abandoned for the current 64-bit support.
Interpreter: Fixed a problem where runtime implicit conversion was incorrectly disabled for the ASL operators below. This brings the behavior into compliance with the ACPI specification:
FromBCD
ToBCD
ToDecimalString
ToHexString
ToInteger
ToBuffer
Table Manager: Added a new public interface, AcpiPutTable, used to release and free an ACPI table returned by AcpiGetTable and related interfaces. Lv Zheng.
Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size.
Current Release:
Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
Debug Version: 201.3K Code, 82.7K Data, 284.0K Total
Previous Release:
Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total
Debug Version: 200.7K Code, 82.1K Data, 282.8K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a regression for disassembly of Resource Template. Detection of templates in the AML stream missed some types of templates.
iASL: Fixed a problem where an Access Size error was returned for the PCC address space when the AccessSize of the GAS register is greater than a DWORD. Hoan Tran.
iASL: Implemented several grammar changes for the operators below. These changes are slated for the next version of the ACPI specification:
RefOf - Disallow method invocation as an operand
CondRefOf - Disallow method invocation as an operand
DerefOf - Disallow operands that use the result from operators that
do not return a reference (Changed TermArg to SuperName).
iASL: Control method invocations are now allowed for Target operands, as per the ACPI specification. Removed error for using a control method invocation as a Target operand.
Disassembler: Improved detection of Resource Templates, Unicode, and Strings within Buffer objects. These subtypes do not contain a specific opcode to indicate the originating ASL code, and they must be detected by other means within the disassembler.
iASL: Implemented an optimization improvement for 32-bit ACPI tables (DSDT/SSDT). For the 32-bit case only, compute the optimum integer opcode only after 64-bit to 32-bit truncation. A truncation warning message is still emitted, however.
AcpiXtract: Implemented handling for both types of line terminators (LF or CR/LF) so that it can accept AcpiDump output files from any system. Peter Wu.
AcpiBin: Added two new options for comparing AML files:
-a: compare and display ALL mismatches
-o: start compare at this offset into the second file

[PATCH] ACPI: allow compilation with bare metal compilers
by Al Stone
The ACPICA subsystem of the ACPI driver sets up a compilation environment
for itself, adding in multiple typedefs unique to ACPICA that depend on
where ACPICA will be used.
The vast majority of such environments (Linux, QNX, ...) have an environment
defined by the acenv.h header file. When using a Linaro compiler [1]
specifically built to be used in an embedded environment with perhaps a
kernel and an init process as the only things running, there is no
environment defined for ACPICA so the typedefs it needs are not set up,
causing compilation to fail badly unless ACPI is completely disabled.
Since ACPI is enabled in the default config for the kernel, the compilation
failure is fairly obvious.
This may not be the optimal solution, but add in to the ACPI header file
include/acpi/platform/acenv.h a default so that if GCC is being used, and
all else fails, assume that we are going to be in a Linux-like environment
and re-use the environment definition for Linux. This allows us to build
a kernel using this compiler [1] with or without ACPI.

patch request for tbxfload.c
by scole_mail
I was hoping this patch could be added. I am trying to run
netbsd/ia64 on a simulator (ski). Without the patch, I get a
segfault. With it, I get the same messages as previous acpica
versions with no seg-faulting.
I'm not sure if it is a just a ia64/ski issue, but it seems like
AcpiGbl_DsdtIndex is never getting set. It looks like only
AcpiTbInstallFixedTable() sets it, but I'm not seeing that called.
AcpiTbInstallTableWithOverride() has a comment saying it sets it, but
I don't see AcpiGbl_DsdtIndex passed to it either.
Output with the patch is below.
Thanks
