Some of the handlers are part of Symbian platform generic code and do not +require porting.

+ + + + +

HAL group

Location

Customizable?

Explicit registration required?

+ + +

EHalGroupVariant

Variant

Yes. It needs to be implemented as the Asic::VariantHal() function +defined by the Asic class.

See the template port: ...\template\template_variant\specific\variant.cpp

No. It is done automatically as part of the kernel initialization.

+ + +

EHalGroupPower

Power model

Yes. It needs to be implemented when implementing the power model.

See +the template port: ...\template\template_variant\specific\power.cpp

No. It is done automatically as part of the kernel initialization.

+ + +

EHalGroupDisplay

LCD driver

Yes, when porting the LCD driver.

See the template port: ...\template\template_variant\specific\lcd.cpp.

Yes, during initialization of the driver.

+ + +

EHalGroupDigitiser

Digitiser

Yes, when porting the digitiser.

See the template port: ...\template\template_variant\specific\xyin.cpp.

Yes, during initialization of the driver.

+ + +

EHalGroupKeyboard

Keyboard driver

Yes, when porting the keyboard driver.

See the template +port: ...\template\template_variant\specific\keyboard.cpp.

Yes, during initialization of the driver.

+ + +

EHalGroupKernel

Kernel

No. It is part of Symbian platform generic code.

No. It is done automatically as part of the kernel initialization.

+ + +

EHalGroupMedia

Media Driver

No. This is in the media driver LDD; this is a kernel extension +and is implemented by Symbian platform.

Yes, during initialization of the driver/extension.

+ + +

EHalGroupEmulator

Emulator

No. The emulator is a port of Symbian platform maintained by Symbian.

Yes, during 3rd phase initialization of the emulator variant.

+ + +

EHalGroupSound

Sound driver

Unlikely—the only example is in the sound driver maintained for +backwards compatibility with pre-Symbian hardware.

Yes

+ + +

EHalGroupMouse

Emulator

Unlikely—the only example is in the emulator, which is a port of +Symbian platform maintained by Symbian.

Yes
