sys/external/common so that they can be used by others.
LGTM from riastradh@
These should really live outside sys/external, but that can be decided
later
Return error code, not 0 (!), on bus_space_subregion failure.
In answer to `XXX error branch' comment: if nouveau_barobj_ctor
fails, then the caller will call nouveau_barobj_dtor too. So there's
no leak here.
Unlikely to fix any observed bugs with nouveau -- there's no error
branch in the Linux side here. But maybe it will catch some other
bug earlier.
Fortunately the last argument, struct socket *so, is used only when
flags includes IP_DF (0x4000), which is not the case here -- we pass
IP_FORWARDING (0x0001).
We previously applied the PCI ROM MD fallback only if the PCI ROM BAR
was altogether unpopulated. Some Radeon devices seem to have a
populated PCI ROM BAR pointing at a bogus ROM, while 0xc0000 works
fine.
Fixes at least one manifestation of PR kern/49964.
----------------------------------------
8 January 2016. Summary of changes for version 20160108:
1) ACPICA kernel-resident subsystem:
Updated all ACPICA copyrights and signons to 2016: Added the 2016
copyright to all source code 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.
Fixed a regression introduced in version 20151218 concerning the
execution of so-called module-level ASL/AML code. Namespace objects
created under a module-level If() construct were not properly/fully
entered into the namespace and could cause an interpreter fault when
accessed.
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: 102.7K Code, 28.4K Data, 131.1K Total
Debug Version: 200.4K Code, 81.9K Data, 282.4K Total
Previous Release:
Non-Debug Version: 102.6K Code, 28.4K Data, 131.0K Total
Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
2) iASL Compiler/Disassembler and Tools:
Fixed a problem with the compilation of the GpioIo and GpioInt resource
descriptors. The _PIN field name was incorrectly defined to be an array
of 32-bit values, but the _PIN values are in fact 16 bits each. This
would cause incorrect bit width warnings when using Word (16-bit) fields
to access the descriptors.
----------------------------------------
18 December 2015. Summary of changes for version 20151218:
1) ACPICA kernel-resident subsystem:
Implemented per-AML-table execution of "module-level code" as individual
ACPI tables are loaded into the namespace during ACPICA initialization.
In other words, any module-level code within an AML table is executed
immediately after the table is loaded, instead of batched and executed
after all of the tables have been loaded. This provides compatibility
with other ACPI implementations. ACPICA BZ 1219. Bob Moore, Lv Zheng,
David Box.
To fully support the feature above, the default operation region handlers
for the SystemMemory, SystemIO, and PCI_Config address spaces are now
installed before any ACPI tables are loaded. This enables module-level
code to access these address spaces during the table load and module-
level code execution phase. ACPICA BZ 1220. Bob Moore, Lv Zheng, David
Box.
Implemented several changes to the internal _REG support in conjunction
with the changes above. Also, changes to the AcpiExec/AcpiNames/Examples
utilities for the changes above. Although these tools were changed, host
operating systems that simply use the default handlers for SystemMemory,
SystemIO, and PCI_Config spaces should not require any update. Lv Zheng.
For example, in the code below, DEV1 is conditionally added to the
namespace by the DSDT via module-level code that accesses an operation
region. The SSDT references DEV1 via the Scope operator. DEV1 must be
created immediately after the DSDT is loaded in order for the SSDT to
successfully reference DEV1. Previously, this code would cause an
AE_NOT_EXIST exception during the load of the SSDT. Now, this code is
fully supported by ACPICA.
DefinitionBlock ("", "DSDT", 2, "Intel", "DSDT1", 1)
{
OperationRegion (OPR1, SystemMemory, 0x400, 32)
Field (OPR1, AnyAcc, NoLock, Preserve)
{
FLD1, 1
}
If (FLD1)
{
Device (\DEV1)
{
}
}
}
DefinitionBlock ("", "SSDT", 2, "Intel", "SSDT1", 1)
{
External (\DEV1, DeviceObj)
Scope (\DEV1)
{
}
}
Fixed an AML interpreter problem where control method invocations were
not handled correctly when the invocation was itself a SuperName argument
to another ASL operator. In these cases, the method was not invoked.
ACPICA BZ 1002. Affects the following ASL operators that have a SuperName
argument:
Store
Acquire, Wait
CondRefOf, RefOf
Decrement, Increment
Load, Unload
Notify
Signal, Release, Reset
SizeOf
Implemented automatic String-to-ObjectReference conversion support for
packages returned by predefined names (such as _DEP). A common BIOS error
is to add double quotes around an ObjectReference namepath, which turns
the reference into an unexpected string object. This support detects the
problem and corrects it before the package is returned to the caller that
invoked the method. Lv Zheng.
Implemented extensions to the Concatenate operator. Concatenate now
accepts any type of object, it is not restricted to simply
Integer/String/Buffer. For objects other than these 3 basic data types,
the argument is treated as a string containing the name of the object
type. This expands the utility of Concatenate and the Printf/Fprintf
macros. ACPICA BZ 1222.
Cleaned up the output of the ASL Debug object. The timer() value is now
optional and no longer emitted by default. Also, the basic data types of
Integer/String/Buffer are simply emitted as their values, without a data
type string -- since the data type is obvious from the output. ACPICA BZ
1221.
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: 102.6K Code, 28.4K Data, 131.0K Total
Debug Version: 200.3K Code, 81.9K Data, 282.3K Total
Previous Release:
Non-Debug Version: 102.0K Code, 28.3K Data, 130.3K Total
Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed some issues with the ASL Include() operator. This operator
was incorrectly defined in the iASL parser rules, causing a new scope to
be opened for the code within the include file. This could lead to
several issues, including allowing ASL code that is technically illegal
and not supported by AML interpreters. Note, this does not affect the
related #include preprocessor operator. ACPICA BZ 1212.
iASL/Disassembler: Implemented support for the ASL ElseIf operator. This
operator is essentially an ASL macro since there is no AML opcode
associated with it. The code emitted by the iASL compiler for ElseIf is
an Else opcode followed immediately by an If opcode. The disassembler
will now emit an ElseIf if it finds an Else immediately followed by an
If. This simplifies the decoded ASL, especially for deeply nested
If..Else and large Switch constructs. Thus, the disassembled code more
closely follows the original source ASL. ACPICA BZ 1211. Example:
Old disassembly:
Else
{
If (Arg0 == 0x02)
{
Local0 = 0x05
}
}
New disassembly:
ElseIf (Arg0 == 0x02)
{
Local0 = 0x05
}
AcpiExec: Added support for the new module level code behavior and the
early region installation. This required a small change to the
initialization, since AcpiExec must install its own operation region
handlers.
AcpiExec: Added support to make the debug object timer optional. Default
is timer disabled. This cleans up the debug object output -- the timer
data is rarely used.
AcpiExec: Multiple ACPI tables are now loaded in the order that they
appear on the command line. This can be important when there are
interdependencies/references between the tables.
iASL/Templates. Add support to generate template files with multiple
SSDTs within a single output file. Also added ommand line support to
specify the number of SSDTs (in addition to a single DSDT). ACPICA BZ
1223, 1225.
----------------------------------------
24 November 2015. Summary of changes for version 20151124:
1) ACPICA kernel-resident subsystem:
Fixed a possible regression for a previous update to FADT handling. The
FADT no longer has a fixed table ID, causing some issues with code that
was hardwired to a specific ID. Lv Zheng.
Fixed a problem where the method auto-serialization could interfere with
the current SyncLevel. This change makes the auto-serialization support
transparent to the SyncLevel support and management.
Removed support for the _SUB predefined name in AcpiGetObjectInfo. This
interface is intended for early access to the namespace during the
initial namespace device discovery walk. The _SUB method has been seen to
access operation regions in some cases, causing errors because the
operation regions are not fully initialized.
AML Debugger: Fixed some issues with the terminate/quit/exit commands
that can cause faults. Lv Zheng.
AML Debugger: Add thread ID support so that single-step mode only applies
to the AML Debugger thread. This prevents runtime errors within some
kernels. Lv Zheng.
Eliminated extraneous warnings from AcpiGetSleepTypeData. Since the _Sx
methods that are invoked by this interface are optional, removed warnings
emitted for the case where one or more of these methods do not exist.
ACPICA BZ 1208, original change by Prarit Bhargava.
Made a major pass through the entire ACPICA source code base to
standardize formatting that has diverged a bit over time. There are no
functional changes, but this will of course cause quite a few code
differences from the previous ACPICA release.
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: 102.0K Code, 28.3K Data, 130.3K Total
Debug Version: 199.6K Code, 81.8K Data, 281.4K Total
Previous Release:
Non-Debug Version: 101.7K Code, 27.9K Data, 129.6K Total
Debug Version: 199.3K Code, 81.4K Data, 280.7K Total
2) iASL Compiler/Disassembler and Tools:
iASL/acpiexec/acpixtract/disassembler: Added support to allow multiple
definition blocks within a single ASL file and the resulting AML file.
Support for this type of file was also added to the various tools that
use binary AML files: acpiexec, acpixtract, and the AML disassembler. The
example code below shows two definition blocks within the same file:
DefinitionBlock ("dsdt.aml", "DSDT", 2, "Intel", "Template",
0x12345678)
{
}
DefinitionBlock ("", "SSDT", 2, "Intel", "Template", 0xABCDEF01)
{
}
iASL: Enhanced typechecking for the Name() operator. All expressions for
the value of the named object must be reduced/folded to a single constant
at compile time, as per the ACPI specification (the AML definition of
Name()).
iASL: Fixed some code indentation issues for the -ic and -ia options (C
and assembly headers). Now all emitted code correctly begins in column 1.
iASL: Added an error message for an attempt to open a Scope() on an
object defined in an SSDT. The DSDT is always loaded into the namespace
first, so any attempt to open a Scope on an SSDT object will fail at
runtime.
----------------------------------------
30 September 2015. Summary of changes for version 20150930:
1) ACPICA kernel-resident subsystem:
Debugger: Implemented several changes and bug fixes to assist support for
the in-kernel version of the AML debugger. Lv Zheng.
- Fix the "predefined" command for in-kernel debugger.
- Do not enter debug command loop for the help and version commands.
- Disallow "execute" command during execution/single-step of a method.
Interpreter: Updated runtime typechecking for all operators that have
target operands. The operand is resolved and validated that it is legal.
For example, the target cannot be a non-data object such as a Device,
Mutex, ThermalZone, etc., as per the ACPI specification.
Debugger: Fixed the double-mutex user I/O handshake to work when local
deadlock detection is enabled.
Debugger: limited display of method locals and arguments (LocalX and
ArgX) to only those that have actually been initialized. This prevents
lines of extraneous output.
Updated the definition of the NFIT table to correct the bit polarity of
one flag: ACPI_NFIT_MEM_ARMED --> ACPI_NFIT_MEM_NOT_ARMED
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: 101.7K Code, 27.9K Data, 129.6K Total
Debug Version: 199.3K Code, 81.4K Data, 280.7K Total
Previous Release:
Non-Debug Version: 101.3K Code, 27.7K Data, 129.0K Total
Debug Version: 198.6K Code, 80.9K Data, 279.5K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Improved the compile-time typechecking for operands of many of the
ASL operators:
-- Added an option to disable compiler operand/operator typechecking (-
ot).
-- For the following operators, the TermArg operands are now validated
when possible to be Integer data objects: BankField, OperationRegion,
DataTableRegion, Buffer, and Package.
-- Store (Source, Target): Both the source and target operands are
resolved and checked that the operands are both legal. For example,
neither operand can be a non-data object such as a Device, Mutex,
ThermalZone, etc. Note, as per the ACPI specification, the CopyObject
operator can be used to store an object to any type of target object.
-- Store (Source, Target): If the source is a Package object, the target
must be a Package object, LocalX, ArgX, or Debug. Likewise, if the target
is a Package, the source must also be a Package.
-- Store (Source, Target): A warning is issued if the source and target
resolve to the identical named object.
-- Store (Source, <method invocation>): An error is generated for the
target method invocation, as this construct is not supported by the AML
interpreter.
-- For all ASL math and logic operators, the target operand must be a
data object (Integer, String, Buffer, LocalX, ArgX, or Debug). This
includes the function return value also.
-- External declarations are also included in the typechecking where
possible. External objects defined using the UnknownObj keyword cannot be
typechecked, however.
iASL and Disassembler: Added symbolic (ASL+) support for the ASL Index
operator:
- Legacy code: Index(PKG1, 3)
- New ASL+ code: PKG1[3]
This completes the ACPI 6.0 ASL+ support as it was the only operator not
supported.
iASL: Fixed the file suffix for the preprocessor output file (.i). Two
spaces were inadvertently appended to the filename, causing file access
and deletion problems on some systems.
ASL Test Suite (ASLTS): Updated the master makefile to generate all
possible compiler output files when building the test suite -- thus
exercising these features of the compiler. These files are automatically
deleted when the test suite exits.
----------------------------------------
18 August 2015. Summary of changes for version 20150818:
1) ACPICA kernel-resident subsystem:
Fix a regression for AcpiGetTableByIndex interface causing it to fail. Lv
Zheng. ACPICA BZ 1186.
Completed development to ensure that the ACPICA Disassembler and Debugger
are fully standalone components of ACPICA. Removed cross-component
dependences. Lv Zheng.
The max-number-of-AML-loops is now runtime configurable (previously was
compile-time only). This is essentially a loop timeout to force-abort
infinite AML loops. ACPCIA BZ 1192.
Debugger: Cleanup output to dump ACPI names and namepaths without any
trailing underscores. Lv Zheng. ACPICA BZ 1135.
Removed unnecessary conditional compilations across the Debugger and
Disassembler components where entire modules could be left uncompiled.
The aapits test is deprecated and has been removed from the ACPICA git
tree. The test has never been completed and has not been maintained, thus
becoming rather useless. ACPICA BZ 1015, 794.
A batch of small changes to close bugzilla and other reports:
- Remove duplicate code for _PLD processing. ACPICA BZ 1176.
- Correctly cleanup after a ACPI table load failure. ACPICA BZ 1185.
- iASL: Support POSIX yacc again in makefile. Jung-uk Kim.
- ACPI table support: general cleanup and simplification. Lv Zheng, Bob
Moore.
- ACPI table support: fix for a buffer read overrun in AcpiTbFindTable.
ACPICA BZ 1184.
- Enhance parameter validation for DataTableRegion and LoadTable ASL/AML
operators.
- Debugger: Split debugger initialization/termination interfaces. Lv
Zheng.
- AcpiExec: Emit OemTableId for SSDTs during the load phase for table
identification.
- AcpiExec: Add debug message during _REG method phase during table
load/init.
- AcpiNames: Fix a regression where some output was missing and no longer
emitted.
- Debugger: General cleanup and simplification. Lv Zheng.
- Disassembler: Cleanup use of several global option variables. 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: 101.3K Code, 27.7K Data, 129.0K Total
Debug Version: 198.6K Code, 80.9K Data, 279.5K Total
Previous Release:
Non-Debug Version: 100.9K Code, 24.5K Data, 125.4K Total
Debug Version: 197.8K Code, 81.5K Data, 279.3K Total
2) iASL Compiler/Disassembler and Tools:
AcpiExec: Fixed a problem where any more than 32 ACPI tables in the XSDT
were not handled properly and caused load errors. Now, properly invoke
and use the ACPICA auto-reallocate mechanism for ACPI table data
structures. ACPICA BZ 1188
AcpiNames: Add command-line wildcard support for ACPI table files. ACPICA
BZ 1190.
AcpiExec and AcpiNames: Add -l option to load ACPI tables only. For
AcpiExec, this means that no control methods (like _REG/_INI/_STA) are
executed during initialization. ACPICA BZ 1187, 1189.
iASL/Disassembler: Implemented a prototype "listing" mode that emits AML
that corresponds to each disassembled ASL statement, to simplify
debugging. ACPICA BZ 1191.
Debugger: Add option to the "objects" command to display a summary of the
current namespace objects (Object type and count). This is displayed if
the command is entered with no arguments.
AcpiNames: Add -x option to specify debug level, similar to AcpiExec.
----------------------------------------
KASSERT() that we don't.
When calculating the load address for the interpreter (e.g. ld.elf_so),
we need to take into account wether the exec'd process will run with
topdown memory or bottom up. We can not use the current vmspace's flags
to test for that, as this happens too early. Luckily the execpack already
knows what the new state will be later, so instead of testing the current
vmspace, pass the info as additional argument to struct emul
e_vm_default_addr.
Fix all such functions and adopt all callers.
surface_height members. idea from the intel code and jmcneill@.
this makes the fb on my RV370 use the full display size, not the
(not actually connected) 800x600 the svideo output supports.
X still starts up at 800x600 mode, but xrandr can fix that.
We stored the bus space handle in nv_subdev(device)->mmioh, which we
then overwrote with whatever was in the mmioh local variable -- maybe
garbage, maybe an old mapping, almost certainly wrong either way.
Instead store it in mmioh so that the subsequent assignment
nv_subdev(device)->mmioh = mmioh actually works as intended.

- hook up an empty uvm_pagerops like radeon does.
- hook up nouveau_ttm_mmap_object().
nouveau_engine_fifo_nve0.c:
- if (cold), don't try to wait, but hard-spin until the timeout period.
with these in place, i am able to get working text-console with nouveau!
ok riastradh.
They reject zero input, and yield zero-based indexing, unlike our
ffs/ffs64, which return zero for zero and yield one-based indexing.
May let nouveau make a little more progress toward booting!
Found by mrg@.
17 July 2015. Summary of changes for version 20150717:
1) ACPICA kernel-resident subsystem:
Improved the partitioning between the Debugger and Disassembler
components. This allows the Debugger to be used standalone within kernel
code without the Disassembler (which is used for single stepping also).
This renames and moves one file, dmobject.c to dbobject.c. Lv Zheng.
Debugger: Implemented a new command to trace the execution of control
methods (Trace). This is especially useful for the in-kernel version of
the debugger when file I/O may not be available for method trace output.
See the ACPICA reference for more information. Lv Zheng.
Moved all C library prototypes (used for the local versions of these
functions when requested) to a new header, acclib.h
Cleaned up the use of non-ANSI C library functions. These functions are
implemented locally in ACPICA. Moved all such functions to a common
source file, utnonansi.c
Debugger: Fixed a problem with the "!!" command (get last command
executed) where the debugger could enter an infinite loop and eventually
crash.
Removed the use of local macros that were used for some of the standard C
library functions to automatically cast input parameters. This mostly
affected the is* functions where the input parameter is defined to be an
int. This required a few modifications to the main ACPICA source code to
provide casting for these functions and eliminate possible compiler
warnings for these parameters.
Across the source code, added additional status/error checking to resolve
issues discovered by static source code analysis tools such as Coverity.
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: 100.9K Code, 24.5K Data, 125.4K Total
Debug Version: 197.8K Code, 81.5K Data, 279.3K Total
Previous Release:
Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total
Debug Version: 196.2K Code, 81.0K Data, 277.2K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a regression where the device map file feature no longer
worked properly when used in conjunction with the disassembler. It only
worked properly with the compiler itself.
iASL: Implemented a new warning for method LocalX variables that are set
but never used (similar to a C compiler such as gcc). This also applies
to ArgX variables that are not defined by the parent method, and are
instead (legally) used as local variables.
iASL/Preprocessor: Finished the pass-through of line numbers from the
preprocessor to the compiler. This ensures that compiler errors/warnings
have the correct original line numbers and filenames, regardless of any
#include files.
iASL/Preprocessor: Fixed a couple of issues with comment handling and the
pass-through of comments to the preprocessor output file (which becomes
the compiler input file). Also fixed a problem with // comments that
appear after a math expression.
iASL: Added support for the TCPA server table to the table compiler and
template generator. (The client table was already previously supported)
iASL/Preprocessor: Added a permanent #define of the symbol "__IASL__" to
identify the iASL compiler.
Cleaned up the use of the macros NEGATIVE and POSITIVE which were defined
multiple times. The new names are ACPI_SIGN_NEGATIVE and
ACPI_SIGN_POSITIVE.
AcpiHelp: Update to expand help messages for the iASL preprocessor
directives.
----------------------------------------
19 June 2015. Summary of changes for version 20150619:
Two regressions in version 20150616 have been addressed:
Fixes some problems/issues with the C library macro removal (ACPI_STRLEN,
etc.) This update changes ACPICA to only use the standard headers for
functions, or the prototypes for the local versions of the C library
functions. Across the source code, this required some additional casts
for some Clib invocations for portability. Moved all local prototypes to
a new file, acclib.h
Fixes several problems with recent changes to the handling of the FACS
table that could cause some systems not to boot.
----------------------------------------
16 June 2015. Summary of changes for version 20150616:
1) ACPICA kernel-resident subsystem:
Across the entire ACPICA source code base, the various macros for the C
library functions (such as ACPI_STRLEN, etc.) have been removed and
replaced by the standard C library names (strlen, etc.) The original
purpose for these macros is no longer applicable. This simplification
reduces the number of macros used in the ACPICA source code
significantly, improving readability and maintainability.
Implemented support for a new ACPI table, the OSDT. This table, the
"override" SDT, can be loaded directly by the host OS at boot time. It
enables the replacement of existing namespace objects that were installed
via the DSDT and/or SSDTs. The primary purpose for this is to replace
buggy or incorrect ASL/AML code obtained via the BIOS. The OSDT is slated
for inclusion in a future version of the ACPI Specification. Lv Zheng/Bob
Moore.
Added support for systems with (improperly) two FACS tables -- a "32-bit"
table (via FADT 32-bit legacy field) and a "64-bit" table (via the 64-bit
X field). This change will support both automatically. There continues to
be systems found with this issue. This support requires a change to the
AcpiSetFirmwareWakingVector interface. Also, a public global variable has
been added to allow the host to select which FACS is desired
(AcpiGbl_Use32BitFacsAddresses). See the ACPICA reference for more
details Lv Zheng.
Added a new feature to allow for systems that do not contain an FACS.
Although this is already supported on hardware-reduced platforms, the
feature has been extended for all platforms. The reasoning is that we do
not want to abort the entire ACPICA initialization just because the
system is seriously buggy and has no FACS.
Fixed a problem where the GUID strings for NFIT tables (in acuuid.h) were
not correctly transcribed from the ACPI specification in ACPICA version
20150515.
Implemented support for the _CLS object in the AcpiGetObjectInfo external
interface.
Updated the definitions of the TCPA and TPM2 ACPI tables to the more
recent TCG ACPI Specification, December 14, 2014. Table disassembler and
compiler also updated. Note: The TCPA "server" table is not supported by
the disassembler/table-compiler at this time.
ACPI 6.0: Added definitions for the new GIC version field in the MADT.
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: 100.6K Code, 27.6K Data, 128.2K Total
Debug Version: 196.2K Code, 81.0K Data, 277.2K Total
Previous Release:
Non-Debug Version: 99.9K Code, 27.5K Data, 127.4K Total
Debug Version: 195.2K Code, 80.8K Data, 276.0K Total
2) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a problem with the new symbolic operator disassembler
where incorrect ASL code could be emitted in some cases for the "non-
commutative" operators -- Subtract, Divide, Modulo, ShiftLeft, and
ShiftRight. The actual problem cases seem to be rather unusual in common
ASL code, however. David Box.
Modified the linux version of acpidump to obtain ACPI tables from not
just /dev/mem (which may not exist) and /sys/firmware/acpi/tables. Lv
Zheng.
iASL: Fixed a problem where the user preprocessor output file (.i)
contained extra data that was not expected. The compiler was using this
file as a temporary file and passed through #line directives in order to
keep compiler error messages in sync with the input file and line number
across multiple include files. The (.i) is no longer a temporary file as
the compiler uses a new, different file for the original purpose.
iASL: Fixed a problem where comments within the original ASL source code
file were not passed through to the preprocessor output file, nor any
listing files.
iASL: Fixed some issues for the handling of the "#include" preprocessor
directive and the similar (but not the same) "Include" ASL operator.
iASL: Add support for the new OSDT in both the disassembler and compiler.
iASL: Fixed a problem with the constant folding support where a Buffer
object could be incorrectly generated (incorrectly formed) during a
conversion to a Store() operator.
AcpiHelp: Updated for new NFIT GUIDs, "External" AML opcode, and new
description text for the _REV predefined name. _REV now permanently
returns 2, as per the ACPI 6.0 specification.
Debugger: Enhanced the output of the Debug ASL object for references
produced by the Index operator. For Buffers and strings, only output the
actual byte pointed to by the index. For packages, only print the single
package element decoded by the index. Previously, the entire
buffer/string/package was emitted.
iASL/Table-compiler: Fixed a regression where the "generic" data types
were no longer recognized, causing errors.
----------------------------------------
15 May 2015. Summary of changes for version 20150515:
This release implements most of ACPI 6.0 as described below.
1) ACPICA kernel-resident subsystem:
Implemented runtime argument checking and return value checking for all
new ACPI 6.0 predefined names. This includes: _BTH, _CR3, _DSD, _LPI,
_MTL, _PRR, _RDI, _RST, _TFP, _TSN.
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: 99.9K Code, 27.5K Data, 127.4K Total
Debug Version: 195.2K Code, 80.8K Data, 276.0K Total
Previous Release:
Non-Debug Version: 99.1K Code, 27.3K Data, 126.4K Total
Debug Version: 192.8K Code, 79.9K Data, 272.7K Total
2) iASL Compiler/Disassembler and Tools:
iASL compiler: Added compile-time support for all new ACPI 6.0 predefined
names (argument count validation and return value typechecking.)
iASL disassembler and table compiler: implemented support for all new
ACPI 6.0 tables. This includes: DRTM, IORT, LPIT, NFIT, STAO, WPBT, XENV.
iASL disassembler and table compiler: Added ACPI 6.0 changes to existing
tables: FADT, MADT.
iASL preprocessor: Added a new directive to enable inclusion of binary
blobs into ASL code. The new directive is #includebuffer. It takes a
binary file as input and emits a named ascii buffer object into the ASL
code.
AcpiHelp: Added support for all new ACPI 6.0 predefined names.
AcpiHelp: Added a new option, -d, to display all iASL preprocessor
directives.
AcpiHelp: Added a new option, -t, to display all known/supported ACPI
tables.
the problem is that we get a SIGALRM while we're sleeping during a page fault
on a mapping of a GEM object, and since we're sleeping interruptibly,
the GEM operation fails with EINTR. this error is returned all the way back
through uvm_fault() to the trap handler, which responds to that error
by delivering a SIGSEGV.
fix this by doing like the linux version of the GEM fault handler and converting
EINTR into success, which results in delivering the original signal and
retrying the fault.
jakllsch@ reports that on some 64-bit systems, kmemdup does 8-byte
reads, which yield garbage in the high word. bus_space_read_region_1
does 1-byte reads instead, which seem to work.
Derived from a patch from jakllsch@.
* Allocate the correct buffer for the VGA BIOS image.
* Abort if buffer allocation failed, not if buffer allocation succeeded.
Not directly tested, but I can't imagine this makes anything worse.
It'll make life simpler. No need to distinguish drm from drm2 here
because it's just an interface attribute, no content, and we use it
compatibly: parent provides pci_attach_args.
Missing part: something needs to issue config_found_ia("drmums_pci"),
and config(5) needs to be told that it will do that. The sensible
approach is for vga_pci to do so. But config(5) doesn't seem to
understand that *only* vga_pci will do that, not all vga.
The old scheme was to tell config(5) that vga would always attach
drm, and actually attach it in vga_pci, and hope that nobody would
ever consider trying to attach non-PCI devices but quietly leave the
token `pci' out of the name of the drm interface attribute so it
didn't look wrong to have it outside dev/pci/files.pci.
Maybe that's still the right thing, as far as anything UMS can be
right.
my PCI 9250 card, and hoses the colours in X when running.
unfortunately, my RV250 does need this to avoid the console being
very very dark on black.
i'm curious what other earlier radeon card (anything matching any
of the card marked as: CHIP_R100, CHIP_RV100, CHIP_RS100,
CHIP_RV200, CHIP_RS200, CHIP_R200, CHIP_RV250, and CHIP_RS300.)
the RV280 now works again properly, but the RV250 is still having
a problem waiting for commands to complete and it appears as if
X is hung, when infact it is asking the kernel quite frequently
if the job it asked for is complete, each time sleeping for a
short time and thus only appearing to take almost no CPU.
- call pmf_device_deregister on detach.
i've kept the "resume = true" for radeon_resume_kms() call as it
seems to work for me (indeed, code inspection shows it is unused
on netbsd :-)
my old nforce4 box that can resume old drm (or could, last i tried
several years ago) while X and GL apps were running, can at least
survive a resume if X hasn't started. my one attempt so far with
X exited, but having run, did not work.
10 April 2015. Summary of changes for version 20150410:
Reverted a change introduced in version 20150408 that caused
a regression in the disassembler where incorrect operator
symbols could be emitted.
----------------------------------------
08 April 2015. Summary of changes for version 20150408:
1) ACPICA kernel-resident subsystem:
Permanently set the return value for the _REV predefined name. It now
returns 2 (was 5). This matches other ACPI implementations. _REV will be
deprecated in the future, and is now defined to be 1 for ACPI 1.0, and 2
for ACPI 2.0 and later. It should never be used to differentiate or
identify operating systems.
Added the "Windows 2015" string to the _OSI support. ACPICA will now
return TRUE to a query with this string.
Fixed several issues with the local version of the printf function.
Added the C99 compiler option (-std=c99) to the Unix makefiles.
Current Release:
Non-Debug Version: 99.9K Code, 27.4K Data, 127.3K Total
Debug Version: 195.2K Code, 80.7K Data, 275.9K Total
Previous Release:
Non-Debug Version: 98.8K Code, 27.3K Data, 126.1K Total
Debug Version: 192.1K Code, 79.8K Data, 271.9K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented an enhancement to the constant folding feature to
transform the parse tree to a simple Store operation whenever possible:
Add (2, 3, X) ==> is converted to: Store (5, X)
X = 2 + 3 ==> is converted to: Store (5, X)
Updated support for the SLIC table (Software Licensing Description Table)
in both the Data Table compiler and the disassembler. The SLIC table
support now conforms to "Microsoft Software Licensing Tables (SLIC and
MSDM). November 29, 2011. Copyright 2011 Microsoft". Note: Any SLIC data
following the ACPI header is now defined to be "Proprietary Data", and as
such, can only be entered or displayed as a hex data block.
Implemented full support for the MSDM table as described in the document
above. Note: The format of MSDM is similar to SLIC. Any MSDM data
following the ACPI header is defined to be "Proprietary Data", and can
only be entered or displayed as a hex data block.
Implemented the -Pn option for the iASL Table Compiler (was only
implemented for the ASL compiler). This option disables the iASL
preprocessor.
Disassembler: For disassembly of Data Tables, added a comment field
around the Ascii equivalent data that is emitted as part of the "Raw
Table Data" block. This prevents the iASL Preprocessor from possible
confusion if/when the table is compiled.
Disassembler: Added an option (-df) to force the disassembler to assume
that the table being disassembled contains valid AML. This feature is
useful for disassembling AML files that contain ACPI signatures other
than DSDT or SSDT (such as OEMx or other signatures).
Changes for the EFI version of the tools:
1) Fixed a build error/issue
2) Fixed a cast warning
iASL: Fixed a path issue with the __FILE__ operator by making the
directory prefix optional within the internal SplitInputFilename
function.
Debugger: Removed some unused global variables.
Tests: Updated the makefile for proper generation of the AAPITS suite.
----------------------------------------
04 February 2015. Summary of changes for version 20150204:
ACPICA kernel-resident subsystem:
Updated all ACPICA copyrights and signons to 2014. Added the 2014
copyright to all module headers and signons, including the standard Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, all ACPICA utilities, and the test suites.
Events: Introduce ACPI_GPE_DISPATCH_RAW_HANDLER to fix GPE storm issues.
A raw gpe handling mechanism was created to allow better handling of GPE
storms that aren't easily managed by the normal handler. The raw handler
allows disabling/renabling of the the GPE so that interrupt storms can be
avoided in cases where events cannot be timely serviced. In this
scenario, handlers should use the AcpiSetGpe() API to disable/enable the
GPE. This API will leave the reference counts undisturbed, thereby
preventing unintentional clearing of the GPE when the intent in only to
temporarily disable it. Raw handlers allow enabling and disabling of a
GPE by removing GPE register locking. As such, raw handlers much provide
their own locks while using GPE API's to protect access to GPE data
structures.
Lv Zheng
Events: Always modify GPE registers under the GPE lock.
Applies GPE lock around AcpiFinishGpe() to protect access to GPE register
values. Reported as bug by joe.liu@apple.com.
Unix makefiles: Separate option to disable optimizations and
_FORTIFY_SOURCE. This change removes the _FORTIFY_SOURCE flag from the
NOOPT disable option and creates a separate flag (NOFORTIFY) for this
purpose. Some toolchains may define _FORTIFY_SOURCE which leads redefined
errors when building ACPICA. This allows disabling the option without
also having to disable optimazations.

Current Release:

07 November 2014. Summary of changes for version 20141107:
This release is available at https://acpica.org/downloads
This release introduces and implements language extensions to ASL that
provide support for symbolic ("C-style") operators and expressions. These
language extensions are known collectively as ASL+.
1) iASL Compiler/Disassembler and Tools:
Disassembler: Fixed a problem with disassembly of the UartSerialBus
macro. Changed "StopBitsNone" to the correct "StopBitsZero". David E.
Box.
Disassembler: Fixed the Unicode macro support to add escape sequences.
All non-printable ASCII values are emitted as escape sequences, as well
as the standard escapes for quote and backslash. Ensures that the
disassembled macro can be correctly recompiled.
iASL: Added Printf/Fprintf macros for formatted output. These macros are
translated to existing AML Concatenate and Store operations. Printf
writes to the ASL Debug object. Fprintf allows the specification of an
ASL name as the target. Only a single format specifier is required, %o,
since the AML interpreter dynamically converts objects to the required
type. David E. Box.
(old) Store (Concatenate (Concatenate (Concatenate (Concatenate
(Concatenate (Concatenate (Concatenate ("", Arg0),
": Unexpected value for "), Arg1), ", "), Arg2),
" at line "), Arg3), Debug)
(new) Printf ("%o: Unexpected value for %o, %o at line %o",
Arg0, Arg1, Arg2, Arg3)
(old) Store (Concatenate (Concatenate (Concatenate (Concatenate
("", Arg1), ": "), Arg0), " Successful"), STR1)
(new) Fprintf (STR1, "%o: %o Successful", Arg1, Arg0)
iASL: Added debug options (-bp, -bt) to dynamically prune levels of the
ASL parse tree before the AML code is generated. This allows blocks of
ASL code to be removed in order to help locate and identify problem
devices and/or code. David E. Box.
AcpiExec: Added support (-fi) for an optional namespace object
initialization file. This file specifies initial values for namespace
objects as necessary for debugging and testing different ASL code paths
that may be taken as a result of BIOS options.
2) Overview of symbolic operator support for ASL (ASL+)
-------------------------------------------------------
As an extension to the ASL language, iASL implements support for symbolic
(C-style) operators for math and logical expressions. This can greatly
simplify ASL code as well as improve both readability and
maintainability. These language extensions can exist concurrently with
all legacy ASL code and expressions.
The symbolic extensions are 100% compatible with existing AML
interpreters, since no new AML opcodes are created. To implement the
extensions, the iASL compiler transforms the symbolic expressions into
the legacy ASL/AML equivalents at compile time.
Full symbolic expressions are supported, along with the standard C
precedence and associativity rules.
Full disassembler support for the symbolic expressions is provided, and
creates an automatic migration path for existing ASL code to ASL+ code
via the disassembly process. By default, the disassembler now emits ASL+
code with symbolic expressions. An option (-dl) is provided to force the
disassembler to emit legacy ASL code if desired.
Below is the complete list of the currently supported symbolic operators
with examples. See the iASL User Guide for additional information.

3) ASL+ Examples:
-----------------
Legacy ASL:
If (LOr (LOr (LEqual (And (R510, 0x03FB), 0x02E0), LEqual (
And (R520, 0x03FB), 0x02E0)), LOr (LEqual (And (R530,

Store (MEMB, Local2)
Store (PDBM, Local1)
And (PDBM, 0xFFFFFFFFFFFFFFF9, PDBM)
Store (SRMB, MEMB)
Or (PDBM, 0x02, PDBM)
}
ASL+ version:
If (((R510 & 0x03FB) == 0x02E0) ||
((R520 & 0x03FB) == 0x02E0) ||
((R530 & 0x03FB) == 0x02E0) ||

{
SRMB = (MEMB & 0xFFFFFFF0)
Local2 = MEMB
Local1 = PDBM
PDBM &= 0xFFFFFFFFFFFFFFF9
MEMB = SRMB
PDBM |= 0x02
}
Legacy ASL:
Store (0x1234, Local1)
Multiply (Add (Add (Local1, TEST), 0x20), Local2, Local3)
Multiply (Local2, Add (Add (Local1, TEST), 0x20), Local3)
Add (Local1, Add (TEST, Multiply (0x20, Local2)), Local3)
Store (Index (PKG1, 0x03), Local6)
Store (Add (Local3, Local2), Debug)
Add (Local1, 0x0F, Local2)
Add (Local1, Multiply (Local2, Local3), Local2)
Multiply (Add (Add (Local1, TEST), 0x20), ToBCD (Local1), Local3)
ASL+ version:
Local1 = 0x1234
Local3 = (((Local1 + TEST) + 0x20) * Local2)
Local3 = (Local2 * ((Local1 + TEST) + 0x20))
Local3 = (Local1 + (TEST + (0x20 * Local2)))
Local6 = Index (PKG1, 0x03)
Debug = (Local3 + Local2)
Local2 = (Local1 + 0x0F)
Local2 = (Local1 + (Local2 * Local3))
Local3 = (((Local1 + TEST) + 0x20) * ToBCD (Local1))
Since we now only count time spent in wait, rather than determining
the end time and checking whether we've passed it, timeouts might be
marginally longer in effect. Unlikely to be an issue.

Leave the CLUT alone on ancient cards. At least this leaves us with a
semi working console (red and blue are flipped). Leave an example of what
seems to be happening but disable it because colors are better than 444 bit
greyscale.
I had assumed for ages this would increase the amount of caching and
thereby increase the chance of stale caches leading to rendering
glitches. But apparently I was wrong, and failing to pass these
through was causing all sorts of problems!
