From 52fc0b026e99b5d5d585095148d997d5634bbc25 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 2 Oct 2006 00:00:00 -0400 Subject: [ACPI] ACPICA 20060210 Removed a couple of extraneous ACPI_ERROR messages that appeared during normal execution. These became apparent after the conversion from ACPI_DEBUG_PRINT. Fixed a problem where the CreateField operator could hang if the BitIndex or NumBits parameter referred to a named object. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5359 Fixed a problem where a DeRefOf operation on a buffer object incorrectly failed with an exception. This also fixes a couple of related RefOf and DeRefOf issues. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5360 http://bugzilla.kernel.org/show_bug.cgi?id=5387 http://bugzilla.kernel.org/show_bug.cgi?id=5392 Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of AE_STRING_LIMIT on an out-of-bounds Index() operation. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5480 Implemented a memory cleanup at the end of the execution of each iteration of an AML While() loop, preventing the accumulation of outstanding objects. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5427 Eliminated a chunk of duplicate code in the object resolution code. From Valery Podrezov. http://bugzilla.kernel.org/show_bug.cgi?id=5336 Fixed several warnings during the 64-bit code generation.

This macro can be defined as necessary to assist kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL macro. The default definition is NULL. Added the ACPI_THREAD_ID type for the return value from acpi_os_get_thread_id(). This allows the host to define this as necessary to simplify kernel integration. The default definition is ACPI_NATIVE_UINT. Valery Podrezov fixed two interpreter problems related to error processing, the deletion of objects, and placing invalid pointers onto the internal operator result stack. http://bugzilla.kernel.org/show_bug.cgi?id=6028 http://bugzilla.kernel.org/show_bug.cgi?id=6151 Increased the reference count threshold where a warning is emitted for large reference counts in order to eliminate unnecessary warnings on systems with large namespaces (especially 64-bit.) Increased the value from 0x400 to 0x800. Due to universal disagreement as to the meaning of the 'c' in the calloc() function, the ACPI_MEM_CALLOCATE macro has been renamed to ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.

With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: Bob Moore Signed-off-by: Len Brown --- drivers/acpi/utilities/utdebug.c | 38 ++++++++++++++++++++++++++++++-------- 1 file changed, 30 insertions(+), 8 deletions(-) (limited to 'drivers/acpi/utilities/utdebug.c') diff --git a/drivers/acpi/utilities/utdebug.c b/drivers/acpi/utilities/utdebug.c index a8c350643d57..5ec1cfcc611d 100644 --- a/drivers/acpi/utilities/utdebug.c +++ b/drivers/acpi/utilities/utdebug.c @@ -517,20 +517,13 @@ acpi_ut_ptr_exit(u32 line_number, * ******************************************************************************/ -void acpi_ut_dump_buffer(u8 * buffer, u32 count, u32 display, u32 component_id) +void acpi_ut_dump_buffer2(u8 * buffer, u32 count, u32 display) { acpi_native_uint i = 0; acpi_native_uint j; u32 temp32; u8 buf_char; - /* Only dump the buffer if tracing is enabled */ - - if (!((ACPI_LV_TABLES & acpi_dbg_level) && - (component_id & acpi_dbg_layer))) { - return; - } - if ((count < 4) || (count & 0x01)) { display = DB_BYTE_DISPLAY; } @@ -556,6 +549,7 @@ void acpi_ut_dump_buffer(u8 * buffer, u32 count, u32 display, u32 component_id) } switch (display) { + case DB_BYTE_DISPLAY: default: /* Default is BYTE display */ acpi_os_printf("%02X ", buffer[i + j]); @@ -613,3 +607,31 @@ void acpi_ut_dump_buffer(u8 * buffer, u32 count, u32 display, u32 component_id) return; } + +/******************************************************************************* + * + * FUNCTION: acpi_ut_dump_buffer + * + * PARAMETERS: Buffer - Buffer to dump + * Count - Amount to dump, in bytes + * Display - BYTE, WORD, DWORD, or QWORD display + * component_iD - Caller's component ID + * + * RETURN: None + * + * DESCRIPTION: Generic dump buffer in both hex and ascii. + * + ******************************************************************************/ + +void acpi_ut_dump_buffer(u8 * buffer, u32 count, u32 display, u32 component_id) +{ + + /* Only dump the buffer if tracing is enabled */ + + if (!((ACPI_LV_TABLES & acpi_dbg_level) && + (component_id & acpi_dbg_layer))) { + return; + } + + acpi_ut_dump_buffer2(buffer, count, display); +} -- cgit v1.2.3
