# [ACPI] ACPICA 20050309 from Bob Moore
#
# The string-to-buffer implicit conversion code has been
# modified again after a change to the ACPI specification.
# In order to match the behavior of the other major ACPI
# implementation, the target buffer is no longer truncated
# if the source string is smaller than an existing target
# buffer. This change requires an update to the ACPI spec,
# and should eliminate the recent AE_AML_BUFFER_LIMIT issues.
#
# The "implicit return" support was rewritten to a new
# algorithm that solves the general case. Rather than
# attempt to determine when a method is about to exit,
# the result of every ASL operator is saved momentarily
# until the very next ASL operator is executed. Therefore,
# no matter how the method exits, there will always be a
# saved implicit return value. This feature is only enabled
# with the acpi_gbl_enable_interpreter_slack flag which
# Linux enables unless "acpi=strict". This should
# eliminate AE_AML_NO_RETURN_VALUE errors.
#
# Implemented implicit conversion support for the predicate
# (operand) of the If, Else, and While operators. String and
# Buffer arguments are automatically converted to Integers.
#
# Changed the string-to-integer conversion behavior to match
# the new ACPI errata: "If no integer object exists, a new
# integer is created. The ASCII string is interpreted as a
# hexadecimal constant. Each string character is interpreted
# as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'),
# starting with the first character as the most significant
# digit, and ending with the first non-hexadecimal character
# or end-of-string." This means that the first non-hex
# character terminates the conversion and this is the code
# that was changed.
#
# Fixed a problem where the ObjectType operator would fail
# (fault) when used on an Index of a Package which pointed
# to a null package element. The operator now properly
# returns zero (Uninitialized) in this case.
#
# Fixed a problem where the While operator used excessive
# memory by not properly popping the result stack during
# execution. There was no memory leak after execution,
# however. (Code provided by Valery Podrezov.)
#
# Fixed a problem where references to control methods within
# Package objects caused the method to be invoked, instead
# of producing a reference object pointing to the method.
#
# Restructured and simplified the pswalk.c module
# (acpi_ps_delete_parse_tree) to improve performance and reduce
# code size. (Code provided by Alexey Starikovskiy.)

# [ACPI] fix kobject_hotplug() use by ACPI processor and container drivers
#
# A while ago, the drivers used their own function
# 'processor_run_sbin_hotplug() and container_run_sbin_hotplug()' to notify
# the agent script using /sbin/hotplug mechanism. But, they were changed to
# use kobject_hotplug() instead and this has caused a side effect.
#
# The container driver was supposed to invoke a container.agent (user mode
# agent script) using /sbin/hotplug mechanism, but after the changes, it is
# not able to call the agent any more and kobject_hotplug() in the
# container.c became to invoke a namespace.agent instead if exists. So, I
# would like to use the namespace.agent to handle container hotplug event (or
# something else) and let the agent to call proper agent (e.g.
# container.agent). But, there is an issue we need to solve. When the
# namespace.agent is called, a path name of associated kobject is passed as a
# DEVPATH (e.g./sys/firmware/ acpi/namespace/ACPI/_SB/DEV0). However, the
# agent would not know what device is associated with the DEVPATH nor which
# agents to call since the DEVPATH name depends on platform. The attached
# patch is to add .hotplug_ops member to acpi_namespace_kset structure and
# let it to set a driver name attached to the target kobject into the envp[]
# variable as a DRV_NAME element. With this, the namespace.agent can call
# proper agents (e.g. container.agent) by refering the DRV_NAME.

# [ACPI] Add ACPI-based memory hot plug driver.
#
# The ACPI based memory hot plug driver patch supports physical hotplug
# operations on memory. This driver fields notifications for memory add
# and remove operations from firmware and notifies the VM of the affected
# memory ranges. Accordingly, this driver also maintains and updates the
# states of all the memory ranges. This driver is useful on hardware which
# helps firmware generating ACPI events for every physical hotplug
# operation of memory boards on the system during runtime.

+ This driver adds supports for ACPI Memory Hotplug. This driver
+ provides support for fielding notifications on ACPI memory
+ devices (PNP0C80) which represent memory ranges that may be
+ onlined or offlined during runtime.
+
+ Enabling this driver assumes that your platform hardware
+ and firmware have support for hot-plugging physical memory. If
+ your system does not support physically adding or ripping out
+ memory DIMMs at some platfrom defined granularity (individually
+ or as a bank) at runtime, then you need not enable this driver.
+
+ If one selects "m," this driver can be loaded using the following
+ command:
+ $>modprobe acpi_memhotplug
