Update to synch with the 20010615 ACPI CA import. Add an ACPI subsystem mutex, and macros for handling it. Because it's not possible to differentiate between ACPI CA acquiring mutexes for internal use and for use by AML, and because AML in the field doesn't handle mutexes correctly, we can't use the ACPI subsystem's internal locking. In addition, we have other private data of our own to lock. Add initial locking to the ACPI driver code and the thermal module. These locks are currently inoperative. Pull some errant style back into line.

Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support. - Add S4BIOS sleep implementation. This will works well if MIB hw.acpi.s4bios is set (and of course BIOS supports it and hibernation is enabled correctly). - Add DSDT overriding support which is submitted by takawata originally. If loader tunable acpi_dsdt_load="YES" and DSDT file is set to acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml), ACPI CA core loads DSDT from given file rather than BIOS memory block. DSDT file can be generated by iasl in ports/devel/acpicatools/. - Add new files so that we can add our proposed additional code to Intel ACPI CA into these files temporary. They will be removed when similar code is added into ACPI CA officially.

This prevents the kernel enables both of them. - Remove obsolete `#ifdef DEV_APM' related code. - Add abstracted interface for Powermanagement operations.

Extend the support for PCI-e memory mapped configuration space access: - Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the rest of the kernel. It now also accepts parameters via function arguments rather than global variables. - Add a notion of minimum and maximum bus numbers and reject requests for an out of range bus. - Add more range checks on slot/func/reg/bytes parameters to the cfg reg read/write routines. Don't panic on any invalid parameters, just fail the request (writes do nothing, reads return -1). This matches the behavior of the other cfg mechanisms. - Port the memory mapped configuration space access to amd64. On amd64 we simply use the direct map (via pmap_mapdev()) for the memory mapped window. - During acpi_attach() just after loading the ACPI tables, check for a MCFG table. If it exists, call pciereg_cfgopen() on each subtable (memory mapped window). For now we only support windows for domain 0 that start with bus 0. This removes the need for more chipset-specific quirks in the MD code. - Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets since these machines should all have MCFG tables via ACPI. - Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen() earlier.

- Convert a lot of homebrew debugging output to use the ACPI CA debugging infrastructure. It's not perfect, but it's a lot better than what we've been using so far. The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now. We may elect to add some new BSD-specific layers later. - Make it possible to turn off selective debugging flags or layers by listing them in debug.acpi.layer or debug.acpi.level prefixed with !. - Fully implement support for avoiding nodes in the ACPI namespace. Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace. - Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace. - Add support for ioctl registration. ACPI subsystem components may register ioctl handlers with the /dev/acpi generic ioctl handler, allowing us to avoid the need for a multitude of /dev/acpi* control devices, etc.

Add two new loader tunables 'hw.acpi.install_interface' and 'hw.acpi.remove_interface'. hw.acpi.install_interface lets you install new interfaces. Conversely, hw.acpi.remove_interface lets you remove OS interfaces from the pre-defined list in ACPICA. For example, hw.acpi.install_interface="FreeBSD" lets _OSI("FreeBSD") method to return 0xffffffff (or success) and hw.acpi.remove_interface="Windows 2009" lets _OSI("Windows 2009") method to return zero (or failure). Both are comma-separated lists and leading white spaces are ignored.

General sleep state change clean up. - Probe supported sleep states from acpi_attach() just once and do not call AcpiGetSleepTypeData() again. It is redundant because AcpiEnterSleepStatePrep() does it any way. - Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions. - Do not set unsupported sleep states as default button/switch events. If the default sleep state is not supported, just set it as UNKNOWN/NONE. - Do not allow sleep state change if the system is not fully up and running. This should prevent entering S5 state multiple times, which causes strange behaviours later. - Make sleep states case-insensitive when they are used with sysctl(8). For example, sysctl hw.acpi.lid_switch_state=s1 sysctl hw.acpi.sleep_button_state=none are now legal and equivalent to the uppercase ones.

Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

Rework sysresource management. Instead of having each sysresource object hold its own values, pass them up to the parent (acpi0) and merge/uniq them on the way. After the namespace evaluation, acpi will reserve these resources and manage them via rman before bus_generic_probe() and bus_generic_attach(). This is necessary because some systems specify conflicting resources in separate sysresource objects. It's also cleaner in that the interface between sysresource and acpi is now merely the parent's resource list. This code handles the following cases: 1. Unique resource: add it to the parent via bus_set_resource(). 2. New wholly contained in old: discard new. 3. New tail overlaps old head: grow old head downward. AND/OR 4. New head overlaps old tail: grow old tail upward. Tested by: Pawel Worach <sajd_at_telia.com> Tested by: Radek Kozlowski <radek_at_raadradd.com> MFC after: 5 days

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting Approved by: re

Extend the support for PCI-e memory mapped configuration space access: - Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the rest of the kernel. It now also accepts parameters via function arguments rather than global variables. - Add a notion of minimum and maximum bus numbers and reject requests for an out of range bus. - Add more range checks on slot/func/reg/bytes parameters to the cfg reg read/write routines. Don't panic on any invalid parameters, just fail the request (writes do nothing, reads return -1). This matches the behavior of the other cfg mechanisms. - Port the memory mapped configuration space access to amd64. On amd64 we simply use the direct map (via pmap_mapdev()) for the memory mapped window. - During acpi_attach() just after loading the ACPI tables, check for a MCFG table. If it exists, call pciereg_cfgopen() on each subtable (memory mapped window). For now we only support windows for domain 0 that start with bus 0. This removes the need for more chipset-specific quirks in the MD code. - Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets since these machines should all have MCFG tables via ACPI. - Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen() earlier.

This was causing a panic in acpi_cpu_idle if the id was 1 since the data was being dereferenced from cpu_softc[1] even though the actual data was in cpu_softc[0] (which is correct). * Rework the initialization functions so that cpu_idle_hook is written late in the boot process. * Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables. This will help SMP boxes that have _CST or multiple P_BLKs. No such boxes are known at this time. * Always allocate the C1 state, even if the P_BLK is invalid.

Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

Turn ACPI and PCI devices off or to a lower power state in suspend and back on again in resume. Override the default of D3 with the value the BIOS specifies in _SxD, if present. Skip serial devices (PNP05xx) since they seem to hang when set to D3 and may require special driver support. Also, skip non-type 0 PCI devices (i.e., bridges) since our we don't yet save/restore their config space and that seems to be necessary. If this gives you trouble with suspend/resume, you can disable the new ACPI and PCI power behavior separately with these tunables & sysctls: debug.acpi.do_powerstate hw.pci.do_powerstate Approved by: imp (pci) Tested by: acpi@ (numerous)

ACPI_SERIAL_DECL(acpi, "ACPI root bus");
Rework sysresource management. Instead of having each sysresource object hold its own values, pass them up to the parent (acpi0) and merge/uniq them on the way. After the namespace evaluation, acpi will reserve these resources and manage them via rman before bus_generic_probe() and bus_generic_attach(). This is necessary because some systems specify conflicting resources in separate sysresource objects. It's also cleaner in that the interface between sysresource and acpi is now merely the parent's resource list. This code handles the following cases: 1. Unique resource: add it to the parent via bus_set_resource(). 2. New wholly contained in old: discard new. 3. New tail overlaps old head: grow old head downward. AND/OR 4. New head overlaps old tail: grow old tail upward. Tested by: Pawel Worach <sajd_at_telia.com> Tested by: Radek Kozlowski <radek_at_raadradd.com> MFC after: 5 days

Rework how the nexus(4) device works on x86 to better handle the idea of different "platforms" on x86 machines. The existing code already handles having two platforms: ACPI and legacy. However, the existing approach was rather hardcoded and difficult to extend. These changes take the approach that each x86 hardware platform should provide its own nexus(4) driver (it can inherit most of its behavior from the default legacy nexus(4) driver) which is responsible for probing for the platform and performing appropriate platform-specific setup during attach (such as adding a platform-specific bus device). This does mean changing the x86 platform busses to no longer use an identify routine for probing, but to move that logic into their matching nexus(4) driver instead. - Make the default nexus(4) driver in nexus.c on i386 and amd64 handle the legacy platform. It's probe routine now returns BUS_PROBE_GENERIC so it can be overriden. - Expose a nexus_init_resources() routine which initializes the various resource managers so that subclassed nexus(4) drivers can invoke it from their attach routine. - The legacy nexus(4) driver explicitly adds a legacy0 device in its attach routine. - The ACPI driver no longer contains an new-bus identify method. Instead it exposes a public function (acpi_identify()) which is a probe routine that the MD nexus(4) drivers can use to probe for ACPI. All of the probe logic in acpi_probe() is now moved into acpi_identify() and acpi_probe() is just a stub. - On i386 and amd64, an ACPI-specific nexus(4) driver checks for ACPI via acpi_identify() and claims the nexus0 device if the probe succeeds. It then explicitly adds an acpi0 device in its attach routine. - The legacy(4) driver no longer knows anything about the acpi0 device. - On ia64 if acpi_identify() fails you basically end up with no devices. This matches the previous behavior where the old acpi_identify() would fail to add an acpi0 device again leaving you with no devices. Discussed with: imp Silence on: arch@

Add two new loader tunables 'hw.acpi.install_interface' and 'hw.acpi.remove_interface'. hw.acpi.install_interface lets you install new interfaces. Conversely, hw.acpi.remove_interface lets you remove OS interfaces from the pre-defined list in ACPICA. For example, hw.acpi.install_interface="FreeBSD" lets _OSI("FreeBSD") method to return 0xffffffff (or success) and hw.acpi.remove_interface="Windows 2009" lets _OSI("Windows 2009") method to return zero (or failure). Both are comma-separated lists and leading white spaces are ignored.

Initial FreeBSD OSPM (operating system power management) modules for ACPICA. Most of these are still works in progress. Support exists for: - Fixed feature and control method power, lid and sleep buttons. - Detection of ISA PnP devices using ACPI namespace. - Detection of PCI root busses using ACPI namespace. - CPU throttling and sleep states (incomplete) - Thermal monitoring and cooling control (incomplete) - Interface to platform embedded controllers (mostly complete) - ACPI timer (incomplete) - Simple userland control of sleep states. - Shutdown and poweroff.

Rework how the nexus(4) device works on x86 to better handle the idea of different "platforms" on x86 machines. The existing code already handles having two platforms: ACPI and legacy. However, the existing approach was rather hardcoded and difficult to extend. These changes take the approach that each x86 hardware platform should provide its own nexus(4) driver (it can inherit most of its behavior from the default legacy nexus(4) driver) which is responsible for probing for the platform and performing appropriate platform-specific setup during attach (such as adding a platform-specific bus device). This does mean changing the x86 platform busses to no longer use an identify routine for probing, but to move that logic into their matching nexus(4) driver instead. - Make the default nexus(4) driver in nexus.c on i386 and amd64 handle the legacy platform. It's probe routine now returns BUS_PROBE_GENERIC so it can be overriden. - Expose a nexus_init_resources() routine which initializes the various resource managers so that subclassed nexus(4) drivers can invoke it from their attach routine. - The legacy nexus(4) driver explicitly adds a legacy0 device in its attach routine. - The ACPI driver no longer contains an new-bus identify method. Instead it exposes a public function (acpi_identify()) which is a probe routine that the MD nexus(4) drivers can use to probe for ACPI. All of the probe logic in acpi_probe() is now moved into acpi_identify() and acpi_probe() is just a stub. - On i386 and amd64, an ACPI-specific nexus(4) driver checks for ACPI via acpi_identify() and claims the nexus0 device if the probe succeeds. It then explicitly adds an acpi0 device in its attach routine. - The legacy(4) driver no longer knows anything about the acpi0 device. - On ia64 if acpi_identify() fails you basically end up with no devices.

This prevents the kernel enables both of them. - Remove obsolete `#ifdef DEV_APM' related code. - Add abstracted interface for Powermanagement operations.

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting Approved by: re

Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

Add two new loader tunables 'hw.acpi.install_interface' and 'hw.acpi.remove_interface'. hw.acpi.install_interface lets you install new interfaces. Conversely, hw.acpi.remove_interface lets you remove OS interfaces from the pre-defined list in ACPICA. For example, hw.acpi.install_interface="FreeBSD" lets _OSI("FreeBSD") method to return 0xffffffff (or success) and hw.acpi.remove_interface="Windows 2009" lets _OSI("Windows 2009") method to return zero (or failure).

Extend the support for PCI-e memory mapped configuration space access: - Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the rest of the kernel. It now also accepts parameters via function arguments rather than global variables. - Add a notion of minimum and maximum bus numbers and reject requests for an out of range bus. - Add more range checks on slot/func/reg/bytes parameters to the cfg reg read/write routines. Don't panic on any invalid parameters, just fail the request (writes do nothing, reads return -1). This matches the behavior of the other cfg mechanisms. - Port the memory mapped configuration space access to amd64. On amd64 we simply use the direct map (via pmap_mapdev()) for the memory mapped window. - During acpi_attach() just after loading the ACPI tables, check for a MCFG table. If it exists, call pciereg_cfgopen() on each subtable (memory mapped window). For now we only support windows for domain 0 that start with bus 0. This removes the need for more chipset-specific quirks in the MD code. - Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets since these machines should all have MCFG tables via ACPI. - Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen() earlier.

Rework the kernel environment subsystem. We now convert the static environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory.

Don't attach special devices in the order they appear in the AML tree. If the embedded controller exists before the sysresource devices, for example, it will be attached first. Instead, let the normal device order function work as we first desired. [1] There still remained a problem where we couldn't allocate resources in acpi0 that were passed up by the sysresource pseudo-devices. These devices had to probe/attach first to give their resources to acpi, then acpi would allocate them before probing/attaching other devices. To work around this, we attach them from acpi_sysres_alloc(). A better approach would be to implement multi-pass probe/attach in newbus but that's a much bigger task.

Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support. - Add S4BIOS sleep implementation. This will works well if MIB hw.acpi.s4bios is set (and of course BIOS supports it and hibernation is enabled correctly). - Add DSDT overriding support which is submitted by takawata originally. If loader tunable acpi_dsdt_load="YES" and DSDT file is set to acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml), ACPI CA core loads DSDT from given file rather than BIOS memory block. DSDT file can be generated by iasl in ports/devel/acpicatools/. - Add new files so that we can add our proposed additional code to Intel ACPI CA into these files temporary. They will be removed when similar code is added into ACPI CA officially.

By default, don't disable ACPI during reboot. This appears to hang some systems. Introduce a new sysctl "hw.acpi.disable_on_reboot" that allows users to re-enable the old behavior in case it's needed for some systems. We never disable in the power-off path.

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting Approved by: re

Update to synch with the 20010615 ACPI CA import. Add an ACPI subsystem mutex, and macros for handling it. Because it's not possible to differentiate between ACPI CA acquiring mutexes for internal use and for use by AML, and because AML in the field doesn't handle mutexes correctly, we can't use the ACPI subsystem's internal locking. In addition, we have other private data of our own to lock. Add initial locking to the ACPI driver code and the thermal module. These locks are currently inoperative. Pull some errant style back into line.

Restructure the wake GPE API. Now there are three functions: acpi_wake_init: Evaluate _PRW and set the GPE type acpi_wake_set_enable: Enable or disable a device's GPE. acpi_wake_sleep_prep: Perform any last-minute changes to the device to prepare it for entering the given sleep state. Also, walk the entire namespace when transitioning to a sleep state, disabling any GPEs which aren't appropriate for the given state. Transition acpi_lid and acpi_button to the new API. This clears the way for non-ACPI-aware devices to wake the system (i.e. modems) and fixes a problem where systems power up after shutdown when a GPE is triggered.

Remove the ACPIIO_ENABLE and ACPIIO_DISABLE ioctls as well as all callers. These ioctls attempted to enable and disable the ACPI interpreter at runtime. In practice, it is not possible to boot with ACPI and then disable it on many systems and trying to do so can cause crashes, interrupt storms, etc. Binary compatibility with userland is retained.

* Handle child resource allocation/removal
*/
Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

Rework sysresource management. Instead of having each sysresource object hold its own values, pass them up to the parent (acpi0) and merge/uniq them on the way. After the namespace evaluation, acpi will reserve these resources and manage them via rman before bus_generic_probe() and bus_generic_attach(). This is necessary because some systems specify conflicting resources in separate sysresource objects. It's also cleaner in that the interface between sysresource and acpi is now merely the parent's resource list. This code handles the following cases: 1. Unique resource: add it to the parent via bus_set_resource(). 2. New wholly contained in old: discard new. 3. New tail overlaps old head: grow old head downward. AND/OR 4. New head overlaps old tail: grow old tail upward. Tested by: Pawel Worach <sajd_at_telia.com> Tested by: Radek Kozlowski <radek_at_raadradd.com> MFC after: 5 days

Don't attach special devices in the order they appear in the AML tree. If the embedded controller exists before the sysresource devices, for example, it will be attached first. Instead, let the normal device order function work as we first desired. [1] There still remained a problem where we couldn't allocate resources in acpi0 that were passed up by the sysresource pseudo-devices. These devices had to probe/attach first to give their resources to acpi, then acpi would allocate them before probing/attaching other devices. To work around this, we attach them from acpi_sysres_alloc(). A better approach would be to implement multi-pass probe/attach in newbus but that's a much bigger task.

In newbus land, ivars can only be accessed for direct child, or when the driver has unholy private knowledge of its great-*cgrandchildren. The ACPI allocation routine lacked such knowledge when it tried to do a default allocation for all descendants, rather than just its immeidate children, so would access grandchild's ivar in an unsafe way. This could lead to a panic when devices were present which had no addresses setup by the BIOS, but which were later allocated in a lazy manner via pci_alloc_map. As such, only do the default allocation adjustments for immediate children. The manner that acpi_sysres_find accesses the resource list, used later in acpi_alloc_resource, is safe and proper so no additional test is needed there. This fixes a panic when probing an disabled ata controller on some newer intel blades. Reported by: dwhite

Use a tighter check to see if a resource allocation request is for a specific request and thus should first try to be allocated from the sys_resource pool. This avoids using the sys_resource pool for wildcard requests that have bounded ranges coming from cbb(4) and Host-PCI pcib(4) drivers.

This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices.

Re-work Cx handling to be per-cpu and asymmetrical, fixing support on modern dual-core systems as well. - Parse the _CST packages for each cpu and track all the states individually, on a per-cpu basis. - Revert to generic FADT/P_BLK based Cx control if the _CST package is not present on all cpus. In that case, the new driver will still support per-cpu Cx state handling. The driver will determine the highest Cx level that can be supported by all the cpus and configure the available Cx state based on that. - Fixed the case where multiple cpus in the system share the same registers for Cx state handling. To do that, added a new flag parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that enable the caller to add the RF_SHAREABLE flag. This flag could also be useful to other callers (acpi_throttle?) in the tree but this change is not yet made. - For Core Duo cpus, both cores seems to be taken out of C3 state when any one of the cores need to transition out. This broke the short sleep detection logic. It is disabled now if there is more than one cpu in the system for now as it fixed it in my case. This quirk may need to be re-enabled later differently. - Added support to control cx_lowest on a per-cpu basis. There is still a generic cx_lowest to enable changing cx_lowest for all cpus with a single sysctl and for ease of use. Sample output for the new sysctl: dev.cpu.0.cx_supported: C1/1 C2/1 C3/57 dev.cpu.0.cx_lowest: C3 dev.cpu.0.cx_usage: 0.00% 43.16% 56.83% dev.cpu.1.cx_supported: C1/1 C2/1 C3/57 dev.cpu.1.cx_lowest: C3 dev.cpu.1.cx_usage: 0.00% 45.65% 54.34% hw.acpi.cpu.cx_lowest: C3 This work was done by Stephane E.

General sleep state change clean up. - Probe supported sleep states from acpi_attach() just once and do not call AcpiGetSleepTypeData() again. It is redundant because AcpiEnterSleepStatePrep() does it any way. - Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions. - Do not set unsupported sleep states as default button/switch events. If the default sleep state is not supported, just set it as UNKNOWN/NONE. - Do not allow sleep state change if the system is not fully up and running. This should prevent entering S5 state multiple times, which causes strange behaviours later. - Make sleep states case-insensitive when they are used with sysctl(8). For example, sysctl hw.acpi.lid_switch_state=s1 sysctl hw.acpi.sleep_button_state=none are now legal and equivalent to the uppercase ones.

Extend the support for PCI-e memory mapped configuration space access: - Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the rest of the kernel. It now also accepts parameters via function arguments rather than global variables. - Add a notion of minimum and maximum bus numbers and reject requests for an out of range bus. - Add more range checks on slot/func/reg/bytes parameters to the cfg reg read/write routines. Don't panic on any invalid parameters, just fail the request (writes do nothing, reads return -1). This matches the behavior of the other cfg mechanisms. - Port the memory mapped configuration space access to amd64. On amd64 we simply use the direct map (via pmap_mapdev()) for the memory mapped window. - During acpi_attach() just after loading the ACPI tables, check for a MCFG table. If it exists, call pciereg_cfgopen() on each subtable (memory mapped window). For now we only support windows for domain 0 that start with bus 0. This removes the need for more chipset-specific quirks in the MD code. - Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets since these machines should all have MCFG tables via ACPI. - Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen() earlier.

Rework sysresource management. Instead of having each sysresource object hold its own values, pass them up to the parent (acpi0) and merge/uniq them on the way. After the namespace evaluation, acpi will reserve these resources and manage them via rman before bus_generic_probe() and bus_generic_attach(). This is necessary because some systems specify conflicting resources in separate sysresource objects. It's also cleaner in that the interface between sysresource and acpi is now merely the parent's resource list. This code handles the following cases: 1. Unique resource: add it to the parent via bus_set_resource(). 2. New wholly contained in old: discard new. 3. New tail overlaps old head: grow old head downward. AND/OR 4. New head overlaps old tail: grow old tail upward. Tested by: Pawel Worach <sajd_at_telia.com> Tested by: Radek Kozlowski <radek_at_raadradd.com> MFC after: 5 days

acpi_probe_order(ACPI_HANDLE handle, int *order)
Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

acpi cpu: probe+attach before all other enumerated children on acpi bus Some current systems dynamically load SSDT(s) when _PDC/_OSC method of Processor is evaluated. Other devices in ACPI namespace may access objects defined in the dynamic SSDT. Drivers for such devices might have to have a rather high priority, because of other dependencies.

Don't attach special devices in the order they appear in the AML tree. If the embedded controller exists before the sysresource devices, for example, it will be attached first. Instead, let the normal device order function work as we first desired. [1] There still remained a problem where we couldn't allocate resources in acpi0 that were passed up by the sysresource pseudo-devices. These devices had to probe/attach first to give their resources to acpi, then acpi would allocate them before probing/attaching other devices. To work around this, we attach them from acpi_sysres_alloc(). A better approach would be to implement multi-pass probe/attach in newbus but that's a much bigger task.

Don't attach special devices in the order they appear in the AML tree. If the embedded controller exists before the sysresource devices, for example, it will be attached first. Instead, let the normal device order function work as we first desired. [1] There still remained a problem where we couldn't allocate resources in acpi0 that were passed up by the sysresource pseudo-devices. These devices had to probe/attach first to give their resources to acpi, then acpi would allocate them before probing/attaching other devices. To work around this, we attach them from acpi_sysres_alloc(). A better approach would be to implement multi-pass probe/attach in newbus but that's a much bigger task.

acpi_probe_order(handle, &order);
Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

- Convert a lot of homebrew debugging output to use the ACPI CA debugging infrastructure. It's not perfect, but it's a lot better than what we've been using so far. The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now. We may elect to add some new BSD-specific layers later. - Make it possible to turn off selective debugging flags or layers by listing them in debug.acpi.layer or debug.acpi.level prefixed with !. - Fully implement support for avoiding nodes in the ACPI namespace. Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace. - Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace. - Add support for ioctl registration.

Add support to ACPI to manage its own resources. Previously, resource allocation was passed up to nexus. Now, we probe sysresource objects and manage the resources they describe in a local rman pool. This helps devices which attach/detach varying resources (like the _CST object) and module loads/unloads. The allocation/release routines now check to see if the resource is described in a child sysresource object and if so, allocate from the local rman. Sysresource objects add their resources to the pool and reserve them upon boot. This means sysresources need to be probed before other ACPI devices. Changes include: * Add ordering to the child device probe. The current order is: system resource objects, embedded controllers, then everything else. * Make acpi_MatchHid take a handle instead of a device_t arg. * Replace acpi_{get,set}_resource with the generic equivalents.

- Convert a lot of homebrew debugging output to use the ACPI CA debugging infrastructure. It's not perfect, but it's a lot better than what we've been using so far. The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now. We may elect to add some new BSD-specific layers later. - Make it possible to turn off selective debugging flags or layers by listing them in debug.acpi.layer or debug.acpi.level prefixed with !. - Fully implement support for avoiding nodes in the ACPI namespace. Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace. - Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace. - Add support for ioctl registration. ACPI subsystem components may register ioctl handlers with the /dev/acpi generic ioctl handler, allowing us to avoid the need for a multitude of /dev/acpi* control devices, etc.

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend.

General sleep state change clean up. - Probe supported sleep states from acpi_attach() just once and do not call AcpiGetSleepTypeData() again. It is redundant because AcpiEnterSleepStatePrep() does it any way. - Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions. - Do not set unsupported sleep states as default button/switch events. If the default sleep state is not supported, just set it as UNKNOWN/NONE. - Do not allow sleep state change if the system is not fully up and running. This should prevent entering S5 state multiple times, which causes strange behaviours later. - Make sleep states case-insensitive when they are used with sysctl(8). For example, sysctl hw.acpi.lid_switch_state=s1 sysctl hw.acpi.sleep_button_state=none are now legal and equivalent to the uppercase ones.

Wakeup event is generated by power button or sleep button on some laptops but this also generates SCI interrupt, and shutdown the system as result.

- Convert a lot of homebrew debugging output to use the ACPI CA debugging infrastructure. It's not perfect, but it's a lot better than what we've been using so far. The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now. We may elect to add some new BSD-specific layers later. - Make it possible to turn off selective debugging flags or layers by listing them in debug.acpi.layer or debug.acpi.level prefixed with !. - Fully implement support for avoiding nodes in the ACPI namespace. Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace. - Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace. - Add support for ioctl registration. ACPI subsystem components may register ioctl handlers with the /dev/acpi generic ioctl handler, allowing us to avoid the need for a multitude of /dev/acpi* control devices, etc.

Also, walk the entire namespace when transitioning to a sleep state, disabling any GPEs which aren't appropriate for the given state. Transition acpi_lid and acpi_button to the new API. This clears the way for non-ACPI-aware devices to wake the system (i.e. modems) and fixes a problem where systems power up after shutdown when a GPE is triggered.

Restructure the wake GPE API. Now there are three functions: acpi_wake_init: Evaluate _PRW and set the GPE type acpi_wake_set_enable: Enable or disable a device's GPE. acpi_wake_sleep_prep: Perform any last-minute changes to the device to prepare it for entering the given sleep state. Also, walk the entire namespace when transitioning to a sleep state, disabling any GPEs which aren't appropriate for the given state. Transition acpi_lid and acpi_button to the new API. This clears the way for non-ACPI-aware devices to wake the system (i.e. modems) and fixes a problem where systems power up after shutdown when a GPE is triggered.

Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE.

General sleep state change clean up. - Probe supported sleep states from acpi_attach() just once and do not call AcpiGetSleepTypeData() again. It is redundant because AcpiEnterSleepStatePrep() does it any way. - Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions. - Do not set unsupported sleep states as default button/switch events. If the default sleep state is not supported, just set it as UNKNOWN/NONE. - Do not allow sleep state change if the system is not fully up and running. This should prevent entering S5 state multiple times, which causes strange behaviours later. - Make sleep states case-insensitive when they are used with sysctl(8). For example, sysctl hw.acpi.lid_switch_state=s1 sysctl hw.acpi.sleep_button_state=none are now legal and equivalent to the uppercase ones.

Because it's not possible to differentiate between ACPI CA acquiring mutexes for internal use and for use by AML, and because AML in the field doesn't handle mutexes correctly, we can't use the ACPI subsystem's internal locking. In addition, we have other private data of our own to lock. Add initial locking to the ACPI driver code and the thermal module. These locks are currently inoperative.

Update to synch with the 20010615 ACPI CA import. Add an ACPI subsystem mutex, and macros for handling it. Because it's not possible to differentiate between ACPI CA acquiring mutexes for internal use and for use by AML, and because AML in the field doesn't handle mutexes correctly, we can't use the ACPI subsystem's internal locking. In addition, we have other private data of our own to lock. Add initial locking to the ACPI driver code and the thermal module. These locks are currently inoperative. Pull some errant style back into line.

Rework the kernel environment subsystem. We now convert the static environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory. The kenv(2) syscall exports these new functionalities to userland, mainly for kenv(1). Reviewed by: peter

Rework the kernel environment subsystem. We now convert the static environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory.

The following rules apply to this: o BSD component names should be capitalised o Layer names should be taken from the non-CA set for now.

Nodes may be listed in the debug.acpi.avoid environment variable; these nodes and all their children will be ignored (although still scanned over) by ACPI functions which scan the namespace. Multiple nodes can be specified, separated by whitespace. - Implement support for selectively disabling ACPI subsystem components via the debug.acpi.disable environment variable. The following components can be disabled: o bus creation/scanning of the ACPI 'bus' o children attachment of children to the ACPI 'bus' o button the acpi_button control-method button driver o ec the acpi_ec embedded-controller driver o isa acpi replacement of PnP BIOS for ISA device discovery o lid the control-method lid switch driver o pci pci root-bus discovery o processor CPU power/speed management o thermal system temperature detection and control o timer ACPI timecounter Multiple components may be disabled by specifying their name(s) separated by whitespace. - Add support for ioctl registration. ACPI subsystem components may register ioctl handlers with the /dev/acpi generic ioctl handler, allowing us to avoid the need for a multitude of /dev/acpi* control devices, etc.

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z.

Support exists for: - Fixed feature and control method power, lid and sleep buttons. - Detection of ISA PnP devices using ACPI namespace. - Detection of PCI root busses using ACPI namespace. - CPU throttling and sleep states (incomplete) - Thermal monitoring and cooling control (incomplete) - Interface to platform embedded controllers (mostly complete) - ACPI timer (incomplete) - Simple userland control of sleep states. - Shutdown and poweroff.

Sync to my work in progress: - Reorder the acpi_* functions in a sensible fashion - Add acpi_ForeachPackageObject and acpi_GetHandleInScope - Use the new debugging layer/level names - Implement most of the guts of the acpi_thermal module; passive cooling isn't there yet, but active cooling should work. - Implement power resource handling (acpi_powerres.c) This compiles and mostly works, but my test coverage is small, so feedback is welcome.

Update to synch with the 20010615 ACPI CA import. Add an ACPI subsystem mutex, and macros for handling it. Because it's not possible to differentiate between ACPI CA acquiring mutexes for internal use and for use by AML, and because AML in the field doesn't handle mutexes correctly, we can't use the ACPI subsystem's internal locking. In addition, we have other private data of our own to lock. Add initial locking to the ACPI driver code and the thermal module. These locks are currently inoperative. Pull some errant style back into line.

- Allow users to enable dumping Debug objects without ACPI debugger. Setting the new sysctl MIB "debug.acpi.enable_debug_objects" to a non-zero value enables us to print Debug object when something is written to it. - Allow users to disable interpreter slack mode. Setting the new tunable "debug.acpi.interpreter_slack" to zero disables some workarounds for common BIOS mistakes and enables strict ACPI implementations by the specification.

Add two new loader tunables 'hw.acpi.install_interface' and 'hw.acpi.remove_interface'. hw.acpi.install_interface lets you install new interfaces. Conversely, hw.acpi.remove_interface lets you remove OS interfaces from the pre-defined list in ACPICA. For example, hw.acpi.install_interface="FreeBSD" lets _OSI("FreeBSD") method to return 0xffffffff (or success) and hw.acpi.remove_interface="Windows 2009" lets _OSI("Windows 2009") method to return zero (or failure). Both are comma-separated lists and leading white spaces are ignored. For example, the following examples are valid: hw.acpi.install_interface="Linux, FreeBSD" hw.acpi.remove_interface="Windows 2006, Windows 2006.1"

Some fix for the recent apm module changes. - Now that apm loadable module can inform its existence to other kernel components (e.g. i386/isa/clock.c:startrtclock()'s TCS hack). - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose. - Add simple arbitration mechanism for APM vs. ACPI. This prevents the kernel enables both of them. - Remove obsolete `#ifdef DEV_APM' related code. - Add abstracted interface for Powermanagement operations. Public apm(4) functions, such as apm_suspend(), should be replaced new interfaces. Currently only power_pm_suspend (successor of apm_suspend) is implemented. Reviewed by: peter, arch@ and audit@

Update the suspend/resume user API while maintaining backwards compat. Improvements: * /etc/rc.suspend,rc.resume are always run, no matter the source of the suspend request (user or kernel, apm or acpi) * suspend now requires positive user acknowledgement. If a user program wants to cancel the suspend, they can. If one of the user programs hangs or doesn't respond within 10 seconds, the system suspends anyway. * /dev/apm is clonable, allowing multiple listeners for suspend events. In the future, xorg-server can use this to be informed about suspend even if there are other listeners (i.e. apmd). Changes: * Two new ACPI ioctls: REQSLPSTATE and ACKSLPSTATE. Request begins the process of suspending by notifying all listeners. acpi is monitored by devd(8) and /dev/apm listener(s) are also counted. Users register their approval or disapproval via Ack. If anyone disapproves, suspend is vetoed. * Old user programs or kernel modules that used SETSLPSTATE continue to work. A message is printed once that this interface is deprecated. * acpiconf gains the -k flag to ack the suspend request. This flag is undocumented on purpose since it's only used by /etc/rc.suspend. It is not intended to be a permanent change and will be removed once a better power API is implemented. * S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z. This restores previous behavior of halt/shutdown -p being the interface. * Miscellaneous improvements to error reporting Approved by: re
