HP DVx ACPI 3.x/4.x Battery Driver (10.6/10.7), HP DVx series laptop battery dri
|
http://www.insanelymac.com/forum/index.php?showtopic=264597
The following implements an Advanced Configuration and Power Interface (ACPI) based battery manager kernel extension (kext/driver) for laptops. It should work correctly on any laptop that correctly implements the ACPI standard DSDT methods as defined in the Advanced Configuration and Power Interface Specification 4.0a. Reference documents used:
The driver has both generic and HP specific functionality that is configurable and it will probably work on all platforms that properly implement the _BST, _BIF and/or _BIX methods in their DSDT. Therefore, there are several installation methods available:
Generic platforms:
HP DVx platforms:
As the HP _BST method on DVx isn't (IMHO) implemented correctly, DVx owners will also have to implement DSDT edits so that the _BST method returns proper values to the driver in order to calculate the time remaining (to charge or discharge) value. In addition, I have rewritten the _BIF method, created a new _BIX and BBIX (Bigger or Better _BIX) to correctly talk to the Smart Battery Subsystem (SBS) via the System Management Bus (SMBus) via the Embedded Controller (EC). This allows the reading of information from the battery that the HP methods do not include like cycle count, temperature and date of manufacture.
The BBIX method, although non-standard, returns *all* of the battery information available from SBS including temperature and is basically an extension of the _BIX method.
This driver polls the battery state by default every 30 seconds. If you wish to override this value to make the system respond to battery events quicker, you can set "BatteryPollingPeriodOverride" in the Info.plist to the number of seconds between polls.
This was tested on an HP DV8 but will likely work on any DVx model that implements similar DSDT methods. Also, I have tested this on both 32-bit/64-bit kernels and the driver has been compiled to a 10.6 32/64-bit universal (FAT) binary. It will also work on 10.7 Lion provided your DSDT methods are performing 8-bit I/O access to the SMBus if accessed through the EC, See "Optional Step 2d: Lion Support for DVx" section for details.
Step 1: ACPI 3.x/4.x _BST DSDT edit (Common to all optional steps below):
In your DSDT.dsl, locate the BAT0 device and add/replace the following:
There is a bug in the HP ITOS() Method used by the optional methods below so locate ITOS() under the Scope(_SB) namespace and replace it with:
Optional Step 2a: ACPI 3.x _BIF with SBS information DSDT edit
In your DSDT.dsl, locate the BAT0 device and add/replace the following:
Optional Step 2b: ACPI 4.x _BIX with SBS information DSDT edit
In your DSDT.dsl, locate the BAT0 device and add/replace the following:
Optional Step 2c: BBIX with all SBS information DSDT edit
In your DSDT.dsl, locate the BAT0 device and add/replace the following:
Optional Step 2d: Lion Support for DVx
Due to stricter ACPI Machine Language (AML) parsing in the AppleACPIPlatform.kext in 10.7 Lion, it appears that any registers in the EC operation region (address space) must be accessed with 8-bit (byte) references. On my DV8, the SMBus that talks to the SBS is wired into the EC and therefore we must access these registers with 8-bit references even though the SMBus standard does provide for 16-bit (Word) access, etc.
The HP DSDT uses two methods under the EC device to read and write the SMBus, SMRD() and SMWR(). I re-wrote the parts of these methods that did Word and Block (string) I/O to do the same thing via bytes so that the AppleACPIPlatform AML parser would not throw an exception. The first thing we need is a new big-old-ugly field definition for accessing the 32 bytes (256 bits) of SMBus data registers. We need to know the offset of these registers, so looking at the Field definition for EmbeddedController operation region we see:
So we can see the SMBus Data Register starts at offset 0x04, so under the EC device add:
Ya, its ugly, but it works. I'm sure this can be done using an index into the field but I need to research this more. Also under the EC device, replace the SMRD and SMWR methods with these:
Compile the DSDT and install as usual.
Step 3: Install Driver
Install the kext in /Extra/Extensions, set the permissions and options in Info.plust, rebuild your kext cache. Reboot.
There are two zip files below, a debug and release version. The debug version outputs messages to kernel.log and the release version does not, otherwise they are identical.

AppleACPIBatteryManager_20110802_debug.zip ( 44.63K ) Number of downloads: 27
The following two drivers are identical to the above versions except the driver classes and kext have been renamed to the same as Apple's Smart Battery Manager and therefore allows some 3rd party application such as iStat Menus and coconutBattery to work.

The driver has both generic and HP specific functionality that is configurable and it will probably work on all platforms that properly implement the _BST, _BIF and/or _BIX methods in their DSDT. Therefore, there are several installation methods available:
Generic platforms:
- ACPI 3.x _BIF method: Configure key "UseExtendedBatteryInformationMethod" to false in Info.plist and install kext.
- ACPI 4.x _BIX method: Configure key "UseExtendedBatteryInformationMethod" to true in Info.plist and install kext.
- Ensure your ACPI _BIF, _BIX, _BST methods return data according to the ACPI specification referenced above.
HP DVx platforms:
As the HP _BST method on DVx isn't (IMHO) implemented correctly, DVx owners will also have to implement DSDT edits so that the _BST method returns proper values to the driver in order to calculate the time remaining (to charge or discharge) value. In addition, I have rewritten the _BIF method, created a new _BIX and BBIX (Bigger or Better _BIX) to correctly talk to the Smart Battery Subsystem (SBS) via the System Management Bus (SMBus) via the Embedded Controller (EC). This allows the reading of information from the battery that the HP methods do not include like cycle count, temperature and date of manufacture.
- To support ACPI 3.x _BIF method: Configure key "UseExtendedBatteryInformationMethod" to false in Info.plist and install kext, Modify DSDT methods UPBS, UPBI and ITOS.
- To support ACPI 4.x _BIX method: Configure key "UseExtendedBatteryInformationMethod" to true in Info.plist and install kext, Modify DSDT methods UPBS, UPBI, ITOS and add _BIX, UPBX and IVBX methods.
- To support non-ACPI BBIX method: Configure key "UseExtraBatteryInformationMethod" to true in Info.plist and install kext, Modify DSDT methods UPBS, UPBI and ITOS and add BBIX, UPBG and IVBG methods.
The BBIX method, although non-standard, returns *all* of the battery information available from SBS including temperature and is basically an extension of the _BIX method.
This driver polls the battery state by default every 30 seconds. If you wish to override this value to make the system respond to battery events quicker, you can set "BatteryPollingPeriodOverride" in the Info.plist to the number of seconds between polls.
This was tested on an HP DV8 but will likely work on any DVx model that implements similar DSDT methods. Also, I have tested this on both 32-bit/64-bit kernels and the driver has been compiled to a 10.6 32/64-bit universal (FAT) binary.

Optional Step 2d: Lion Support for DVx
Due to stricter ACPI Machine Language (AML) parsing in the AppleACPIPlatform.kext in 10.7 Lion, it appears that any registers in the EC operation region (address space) must be accessed with 8-bit (byte) references. On my DV8, the SMBus that talks to the SBS is wired into the EC and therefore we must access these registers with 8-bit references even though the SMBus standard does provide for 16-bit (Word) access, etc.
The HP DSDT uses two methods under the EC device to read and write the SMBus, SMRD() and SMWR(). I re-wrote the parts of these methods that did Word and Block (string) I/O to do the same thing via bytes so that the AppleACPIPlatform AML parser would not throw an exception. The first thing we need is a new big-old-ugly field definition for accessing the 32 bytes (256 bits) of SMBus data registers. We need to know the offset of these registers, so looking at the Field definition for EmbeddedController operation region we see:
CODE
// Embedded controller I/O Registers
// SMBus mapped at offset 0x00
OperationRegion (ERAM, EmbeddedControl, Zero, 0xFF)
Field (ERAM, ByteAcc, Lock, Preserve)
{
SMPR, 8, // SMBus Protocol Register
SMST, 8, // SMBus Status Register
SMAD, 8, // SMBus Address Register
SMCM, 8, // SMBus Command Register
SMD0, 256, // SMBus Data Register[0-31] ( 32 byte buffer)
BCNT, 8, // SMBus Block Count Register
SMAA, 8, // SMBus Alarm Address Register
SAD0, 8, // SMBus Alarm Data Register[0]
SAD1, 8, // SMBus Alarm Data Register[1]
...
// SMBus mapped at offset 0x00
OperationRegion (ERAM, EmbeddedControl, Zero, 0xFF)
Field (ERAM, ByteAcc, Lock, Preserve)
{
SMPR, 8, // SMBus Protocol Register
SMST, 8, // SMBus Status Register
SMAD, 8, // SMBus Address Register
SMCM, 8, // SMBus Command Register
SMD0, 256, // SMBus Data Register[0-31] ( 32 byte buffer)
BCNT, 8, // SMBus Block Count Register
SMAA, 8, // SMBus Alarm Address Register
SAD0, 8, // SMBus Alarm Data Register[0]
SAD1, 8, // SMBus Alarm Data Register[1]
...
So we can see the SMBus Data Register starts at offset 0x04, so under the EC device add:
CODE
// Define 8-bit fields for accessing SMBus data registers [0-31]
Field (ERAM, ByteAcc, Lock, Preserve)
{
Offset (0x04),
SM00, 8,
SM01, 8,
SM02, 8,
SM03, 8,

SM20, 8,
SM21, 8,
SM22, 8,
SM23, 8,
SM24, 8,
SM25, 8,
SM26, 8,
SM27, 8,
SM28, 8,
SM29, 8,
SM30, 8,
SM31, 8
}
Field (ERAM, ByteAcc, Lock, Preserve)
{
Offset (0x04),
SM00, 8,
SM01, 8,
SM02, 8,
SM03, 8,
SM04, 8,
SM05, 8,
SM06, 8,
SM07, 8,
SM08, 8,

Ya, its ugly, but it works. I'm sure this can be done using an index into the field but I need to research this more. Also under the EC device, replace the SMRD and SMWR methods with these:

Compile the DSDT and install as usual.
Step 3: Install Driver
Install the kext in /Extra/Extensions, set the permissions and options in Info.plust, rebuild your kext cache. Reboot.
There are two zip files below, a debug and release version. The debug version outputs messages to kernel.log and the release version does not, otherwise they are identical.
