Re: [Devel] Devel Digest, Vol 72, Issue 1: ACPICA version 20161117 released (Moore, Robert)
by Alexei Fedorov
Hi,
When ACPI IORT template is created with "iasl.exe -T IORT", the generated ITS group node
also contains 1 entry in the array of ID mappings:
[0001] Type : 00
[0002] Length : 002C
[0001] Revision : 00
[0004] Reserved : 00000000
[0004] Mapping Count : 00000001
[0004] Mapping Offset : 00000018
[0004] ItsCount : 00000001
[0004] Identifiers : 00000000
[0004] Input base : 00000000
[0004] ID Count : 00000000
[0004] Output Base : 00000000
[0004] Output Reference : 00000000
[0004] Flags (decoded below) : 00000000
Single Mapping : 0
This contradicts with the IO Remapping Table specification
(http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Rem...) Table 11 which reads:
"Number of ID mappings: This field has a value of 0. ITS groups do not have IDs.
Reference to ID Array: This field has a value of 0. There is no ID array."
That implies that "Mapping Count" and "Mapping Offset" fields should be set to 0 and ID array
data removed.
If the Iort.asl template is compiled and then Iort.aml binary disassembled to Iort.dsl,
SMMUv1 node lists incorrect offset for SMMU_NSgCfgIrpt Interrupt which has the same [0ECh 0236] value as for SMMU_NSgIrpt:
[0ECh 0236 8] SMMU_NSgIrpt Interrupt : 0000000000000000
[0ECh 0236 8] SMMU_NSgCfgIrpt Interrupt : 0000000000000000
but should be set to [0F4h 0244]
Alexei.

Sure, that's understood from the current structure. The issue is #3 -- there is no OS, in the sense of a run-time environment, so that assumption is incorrect in this case. All we know is that we're compiling the kernel and it needs to be able to run in complete isolation.

Right, which is what this patch is relying on.

I'm confused; I thought that was what this patch was doing. What is being suggested instead?

This option might force changes in the kernel build which is otherwise not affected; this is only an issue with drivers/acpi/acpica/*. It may also cause ACPICA to build incorrectly for other OSs, but I'll have to look at that. Off hand, it seems like this would cause more problems with acenv.h.

Understood, which is why I left the #error case; the intent is only to have a default when compiling Linux for bare-metal environments using GCC. Perhaps this is just a Linux-only modification...

Subject: [Devel] patch request for tbxfload.c
Message-ID: <87poly0zhq.fsf(a)gmx.com>
Content-Type: text/plain
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

Message-ID:
<94F2FBAB4432B54E8AACC7DFDE6C92E37E52E0B6(a)ORSMSX110.amr.corp.intel.com>
Content-Type: text/plain; charset="us-ascii"
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

IIRC, very old versions of the FACS were < 32 bytes long; those old versions
did not have a XFirmwareWakingVector field, or a proper Version field. For
that case, the function just returns after doing nothing. If the FACS is
larger than 32 bytes, it should have a Version field, but it looks like version
1 does not have a usable XFirmwareWakingVector field -- i.e., it is defined in
the struct, but is not valid until a later version of the ACPI specification
where Facs->Version >= 2. So, for Version == 1, ignore the field, but for
versions > 1, set the field.
Does that help?

You can use ACPI_PRINTF_LIKE macro instead.
This can directly go into Linux upstream.
You can prepare a different pull request for ACPICA upstream or
I can help to back port the change.

[PATCH v2] EFI: fix build for AARCH64
by Leif Lindholm
AARCH64 build was left out of initial version, so add to .dsc and set
ACPI_MACHINE_WIDTH correctly.
Also, acpidump.inf specified explicit per-architecture (but identical)
CFLAGS. Rather than duplicating this further, use the same setting for
all architectures until there is actually a need to diverge.
Also update README to make it obvious AArch64 is supported.
Signed-off-by: Leif Lindholm <leif.lindholm(a)linaro.org>

v2 contains a fix for a non-functional issue, which could generate
warnings when building with CLANG.

[PATCH] iASL: Predefine names: make argument errors more understandable
by Colin King
From: Colin Ian King <colin.king(a)canonical.com>
The current errors print out the number of arguments but is not clear
what these values mean. Clarify the error messages by specifically
mentioning that these refer to the number of arguments. I took the
liberty to replace the %u and 0 with the text 'zero' to match the
style found in other similar error messages.

ACPICA version 20170119 released
by Moore, Robert
19 January 2017. Summary of changes for version 20170119:
This release is available at https://acpica.org/downloads
1) General ACPICA software:
Entire source code base: Added the 2017 copyright to all source code
legal/licensing module headers and utility/tool signons. This includes
the standard Linux dual-license header. This affects virtually every file
in the ACPICA core subsystem, iASL compiler, all ACPICA utilities, and
the ACPICA test suite.
2) iASL Compiler/Disassembler and Tools:
iASL: Removed/fixed an inadvertent remark when a method argument
containing a reference is used as a target operand within the method (and
never used as a simple argument), as in the example below. Jeffrey Hugo.
dsdt.asl 1507: Store(0x1, Arg0)
Remark 2146 - ^ Method Argument is never used (Arg0)
All tools: Removed the bit width of the compiler that generated the tool
from the common signon for all user space tools. This proved to be
confusing and unnecessary. This includes similar removal of HARDWARE_NAME
from the generic makefiles (Thomas Petazzoni). Example below.
Old:
ASL+ Optimizing Compiler version 20170119-32
ASL+ Optimizing Compiler version 20170119-64
New:

Missing _BQC method
by Anthony Jenkins
What may the OSPM assume/do about a missing _BQC (Brightness Query
Current level) method? The last two HP ENVY laptops I owned do not have
this method, and FreeBSD's acpi_video driver (currently) requires it to
control screen brightness - unless I can assume _only_ the OSPM can set
the screen brightness. My current workaround is a patch to the DSDT to
add a simple method that copies and returns a variable used by _BCM
(Brightness Control Method).
Thanks in advance,
