Subject: please test latest acpi patch
Date: 19 Mar 2005 01:34:06 -0500 [thread overview]
Message-ID: <1111214045.5932.41.camel@d845pe> (raw)
There are some very important -- and in some cases,
potentially disruptive -- changes in the latest ACPI patch.
EC Burst Mode -- battery status AE_TIME etc.
Binding ACPI power states to PCI devices -- power loss in S3
Generic Hot Key Driver -- needs configuration from user space
S3 Resume PCI Interrupt Link fix, requiring drivers to behave better
Poweroff fix -- compatible with kexec patch
Improved "Implicit Return" AML workaround -- toshiba, compaq etc.
Relaxed AE_AML_BUFFER_LIMIT code -- reflects proposed ACPI spec update
Please try it out on a system near you!
Thanks,
-Len

Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:
.find_device:
For device which has parent such as normal PCI devices.
.find_bridge:
It's for special devices, such as PCI root bridge
or IDE controller. Such devices generally haven't a
parent or ->bus. We use the special method
to get an ACPI handle.

[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] ACPICA 20050303 from Bob Moore for AE_AML_BUFFER_LIMIT issue.
It turns out that tightening up the interpreter to truncate buffers
per the ACPI spec was a bad idea -- BIOS' in the field depended
on old behaviour. Instead, we'll endeavor to update the ACPI spec
to reflect industry practice in this area.

[ACPI] fix sysfs "eject" file
This fixes a if-statement in setup_sys_fs_device_files(). It seems
to
assume that 'struct acpi_device_flags.ejectable' indicates whether a
device
has _EJ0 or not. But this is not a right assumption. It indicates
whether
a device has _EJ0|_EJD (See acpi_bus_get_flags() function).
setup_sys_fs_device_files() creates 'eject' file for devices that
have _EJ0
control method under a corresponding directory in
/sys/firmware/acpi/namespace/ACPI/. 'eject' file is used to trigger
hot-removal function from userland.

[ACPI] fix ACPI container driver's notify handler.
Previously, the handler tried to make a container device be offline
if an
ACPI_NOTIFY_BUS/DEVICE_CHECK notification is performed on the device
was
present and has its acpi_device. But, the condition is weird.
Whenever
the notification is performed, there should be only the following two
conditions:
1. the device is present, but does not have its acpi_device.
2. the device is not present, but has its acpi_device.
#1 is a hot-addition case, which was handled properly also in
previous
handler. #2 is a surprising hot-removal case, which was not handled
in
previous handler.

[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.
