* ACPICA: Add a lock to the internal object reference count mechanismBob Moore2013-04-121-1/+8
| | | | | | | | | | | | | Certain external interfaces need to update object references without holding the interpreter or namespace mutex objects. To prevent race conditions, add a spinlock around the increment and decrement of the reference counts for internal ACPI objects. Reported by Andriy Gapon (avg@FreeBSD.org).

| | | | | | | | | | | 1) Ensure that all functions that use the various TRACE macros also use the appropriate ACPICA return macros. 2) Ensure that all normal return statements surround the return expression (value) with parens.

* ACPICA: Fix code divergence of global lock handlingLin Ming2011-03-251-5/+0Star
| | | | | | | | | | | | | | | | Commit 9cd0314(ACPI / ACPICA: Fix global lock acquisition) was backported into ACPICA code base, and some divergence was introduced. This patch fixed it, - rename acpi_ev_global_lock_pending/acpi_ev_global_lock_pending_lock to acpi_gbl_global_lock_pending/acpi_gbl_global_lock_pending_lock. - move the initialization of acpi_gbl_global_lock_pending_lock from acpi_ut_mutex_initialize to acpi_ev_init_global_lock_handler.

* ACPICA: Make acpi_thread_id no longer configurable, always u64Lin Ming2010-10-011-13/+16
| | | | | | | | | | | | | Change definition of acpi_thread_id to always be a u64. This simplifies the code, especially any printf output. u64 is the only common data type for all thread_id types across all operating systems. We now force the OSL to cast the native thread_id type to u64 before returning the value to ACPICA (via acpi_os_get_thread_id).

* ACPICA/ACPI: Add new host interfaces for _OSI supportLin Ming2010-10-011-0/+8
| | | | | | | | | | | | | | | | | | | | Adds install/remove interfaces so that the host can dynamically alter the global _OSI table. Also adds support for _OSI handlers. Additional support: new debugger command (osi), and test support in the acpiexec utility. Adds new file, utilities/utosi.c. ACPICA bugzilla 836. The Linux OSL _OSI code is also changed. acpi_osi_setup can't call acpi_install/remove_interface because ACPICA is not initialized yet at this early time. So we just save the osi string in acpi_osi_setup and will handle it later in a new function acpi_osi_setup_late. http://www.acpica.org/bugzilla/show_bug.cgi?id=836 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com Signed-off-by: Len Brown <len.brown@intel.com>

* ACPICA: Fix possible warnings for ACPI_THREAD_ID on 64-bit buildBob Moore2009-05-271-13/+13
| | | | | | | | | | | Warnings can be generated for printf-like statements that output the ACPI_THREAD_ID on 64-bit builds, since this type can expand to 64-bits depending on how it is defined. Use the %p format specifier to allow the output to automatically expand to 64 bits.

* ACPICA: Fix AcpiWalkNamespace race condition with table unloadBob Moore2009-03-271-8/+15
| | | | | | | | | | | | | | | Added a reader/writer locking mechanism to allow multiple concurrent namespace walks (readers), but a dynamic table unload will have exclusive access to the namespace. This fixes a problem where a table unload could delete the portion of the namespace that is currently being examined by a walk. Adds a new file, utlock.c that implements the reader/writer lock mechanism.
