      ACPI: fix 2.6.28 acpi.debug_level regression · e76f4276
      Bjorn Helgaas authored
      acpi_early_init() was changed to over-write the cmdline param,
      making it really inconvenient to set debug flags at boot-time.
      
      Also,
      This sets the default level to "info", which is what all the ACPI
      drivers use.  So to enable messages from drivers, you only have to
      supply the "layer" (a.k.a. "component").  For non-"info" ACPI core
      and ACPI interpreter messages, you have to supply both level and
      layer masks, as before.

      ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE · 798d9103
      Thomas Renninger authored
      Split ACPI_DEBUG into function trace enabled and not enabled.
      
      Function trace is most of the ACPI_DEBUG costs, but is
      not much of use for kernel ACPI debugging.
      
      Size of kernel image increased on test compile:
      + 48k  (Full ACPI_DEBUG)
      + 35k  (ACPI_DEBUG with function trace compiled out)
      
      Performance without function trace is also much better.
      
      Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
      a lot vendors let Store (value, debug) in their code and this
      might confuse users when it pops up in syslog.

      ACPI: ACPICA 20060421 · b229cf92

      Removed a device initialization optimization introduced in
      20051216 where the _STA method was not run unless an _INI
      was also present for the same device. This optimization
      could cause problems because it could allow _INI methods
      to be run within a not-present device subtree (If a
      not-present device had no _INI, _STA would not be run,
      the not-present status would not be discovered, and the
      children of the device would be incorrectly traversed.)
      
      Implemented a new _STA optimization where namespace
      subtrees that do not contain _INI are identified and
      ignored during device initialization. Selectively running
      _STA can significantly improve boot time on large machines
      (with assistance from Len Brown.)
      
      Implemented support for the device initialization case
      where the returned _STA flags indicate a device not-present
      but functioning. In this case, _INI is not run, but the
      device children are examined for presence, as per the
      ACPI specification.
      
      Implemented an additional change to the IndexField support
      in order to conform to MS behavior. The value written to
      the Index Register is not simply a byte offset, it is a
      byte offset in units of the access width of the parent
      Index Field. (Fiodor Suietov)
      
      Defined and deployed a new OSL interface,
      acpi_os_validate_address().  This interface is called during
      the creation of all AML operation regions, and allows
      the host OS to exert control over what addresses it will
      allow the AML code to access. Operation Regions whose
      addresses are disallowed will cause a runtime exception
      when they are actually accessed (will not affect or abort
      table loading.)
      
      Defined and deployed a new OSL interface,
      acpi_os_validate_interface().  This interface allows the host OS
      to match the various "optional" interface/behavior strings
      for the _OSI predefined control method as appropriate
      (with assistance from Bjorn Helgaas.)
      
      Restructured and corrected various problems in the
      exception handling code paths within DsCallControlMethod
      and DsTerminateControlMethod in dsmethod (with assistance
      from Takayoshi Kochi.)
      
      Modified the Linux source converter to ignore quoted string
      literals while converting identifiers from mixed to lower
      case. This will correct problems with the disassembler
      and other areas where such strings must not be modified.
      
      The ACPI_FUNCTION_* macros no longer require quotes around
      the function name. This allows the Linux source converter
      to convert the names, now that the converter ignores
      quoted strings.

      Bob Moore authored
      Implemented the use of a cache object for all internal
      namespace nodes. Since there are about 1000 static nodes
      in a typical system, this will decrease memory use for
      cache implementations that minimize per-allocation overhead
      (such as a slab allocator.)
      
      Removed the reference count mechanism for internal
      namespace nodes, since it was deemed unnecessary. This
      reduces the size of each namespace node by about 5%-10%
      on all platforms. Nodes are now 20 bytes for the 32-bit
      case, and 32 bytes for the 64-bit case.
      
      Optimized several internal data structures to reduce
      object size on 64-bit platforms by packing data within
      the 64-bit alignment. This includes the frequently used
      ACPI_OPERAND_OBJECT, of which there can be ~1000 static
      instances corresponding to the namespace objects.
      
      Added two new strings for the predefined _OSI method:
      "Windows 2001.1 SP1" and "Windows 2006".
      
      Split the allocation tracking mechanism out to a separate
      file, from utalloc.c to uttrack.c. This mechanism appears
      to be only useful for application-level code. Kernels may
      wish to not include uttrack.c in distributions.
      
      Removed all remnants of the obsolete ACPI_REPORT_* macros
      and the associated code. (These macros have been replaced
      by the ACPI_ERROR and ACPI_WARNING macros.)

      Added 2006 copyright.
      
      At SuSE's suggestion, enabled all error messages
      without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n
      
      Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
      the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
      the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
      respectively. This preserves all error and warning messages
      in the non-debug version of the ACPICA code (this has been
      referred to as the "debug lite" option.) Over 200 cases
      were converted to create a total of over 380 error/warning
      messages across the ACPICA code. This increases the code
      and data size of the default non-debug version by about 13K.
      Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
      The size of the debug version remains about the same.

      ACPICA 20050708 from Bob Moore <robert.moore@intel.com> · f9f4601f

      The use of the CPU stack in the debug version of the
      subsystem has been considerably reduced.  Previously, a
      debug structure was declared in every function that used
      the debug macros.  This structure has been removed in
      favor of declaring the individual elements as parameters
      to the debug functions.  This reduces the cumulative stack
      use during nested execution of ACPI function calls at the
      cost of a small increase in the code size of the debug
      version of the subsystem.  With assistance from Alexey
      Starikovskiy and Len Brown.
      
      Added the ACPI_GET_FUNCTION_NAME macro to enable the
      compiler-dependent headers to define a macro that will
      return the current function name at runtime (such as
      __FUNCTION__ or _func_, etc.) The function name is used
      by the debug trace output.  If ACPI_GET_FUNCTION_NAME
      is not defined in the compiler-dependent header, the
      function name is saved on the CPU stack (one pointer per
      function.) This mechanism is used because apparently there
      exists no standard ANSI-C defined macro that that returns
      the function name.
      
      Alexey Starikovskiy redesigned and reimplemented the
      "Owner ID" mechanism used to track namespace objects
      created/deleted by ACPI tables and control method
      execution.  A bitmap is now used to allocate and free the
      IDs, thus solving the wraparound problem present in the
      previous implementation.  The size of the namespace node
      descriptor was reduced by 2 bytes as a result.
      
      Removed the UINT32_BIT and UINT16_BIT types that were used
      for the bitfield flag definitions within the headers for
      the predefined ACPI tables.  These have been replaced by
      UINT8_BIT in order to increase the code portability of
      the subsystem.  If the use of UINT8 remains a problem,
      we may be forced to eliminate bitfields entirely because
      of a lack of portability.
      
      Alexey Starikovksiy enhanced the performance of
      acpi_ut_update_object_reference.  This is a frequently used
      function and this improvement increases the performance
      of the entire subsystem.
      
      Alexey Starikovskiy fixed several possible memory leaks
      and the inverse - premature object deletion.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
