building kext for all architectures

Build Active Architecture Only -> NO

IOWorkLoop

command gate event source:
ex:

this->testCommandGate->runAction(OSMemberFunctionCast(IOCommandGate::Action,

                                                          this, &com_peter_driver_MyDriver::myCommandGateAction),

this->getProvider(), NULL, NULL, NULL);

the command gate action, myCommandGateAction, is executed by thread that call runAction
if A call testCommandGate's runAction, and B call testCommandGate's runAction later,
B will wait until A finishes

subclass IOEventSource:
is executed by newly created thread
checkForWork will repeatedly be called until it return false
do the task in checkForWork
use enable() to trigger checkForWork to be called

get current thread in mac driver

IOThreadSelf():

ex:

IOLog("Starting current thread %p\n", 

  IOThreadSelf());

kextlibs - find symbols in kext

ex:
kextlibs  -all-symbols TestIokitDriver2.kext

mac driver plist

mac driver plist

mac driver:

1. CFBundleIdentifier

unique id for kext

ex:

com.deeplove.test

it does not need to match with IOClass

2. OSBundleLibraries

define depended libraries

we can use kextlibs to find linked libraries

ex:

kextlibs -xml GenericKext.kext

->

<key>OSBundleLibraries</key>

<dict>

<key>com.apple.kpi.libkern</key>

<string>10.4</string>

</dict>

the match version number lib is define in OSBundleCompatibleVersion

ex:

<key>OSBundleCompatibleVersion</key>

<string>1.0</string>

3. IOKitPersonalities

ex:

<key>IOKitPersonalities</key>

<dict>

<key>MyIokitDriver</key>

<dict>

<key>CFBundleIdentifier</key>

<string>com.yourcompany.driver.MyIokitDriver</string>

<key>IOClass</key>

<string>com_yourcompany_driver_MyIokitDriver</string>

<key>IOKitDebug</key>

<integer>65535</integer>

<key>IOProviderClass</key>

<string>IOResources</string>

<key>IOMatchCategory</key>

<string>com_yourcompany_driver_MyIokitDriver</string>

</dict>

</dict>

CFBundleIdentifier in IOKitPersonalities must be the same  with outer CFBundleIdentifier

IOProviderClass:

 indicates the class of the provider objects that your driver can match on

IOMatchCategory:

 allows other drivers to match on the same device as your driver,

 as long as the drivers values for this property differ

create install package for kext

reference:
http://developer.apple.com/library/mac/#documentation/Darwin/Conceptual/KEXTConcept/KEXTConceptPackaging/packaging_tutorial.html%23//apple_ref/doc/uid/20002368-CHDCBCJA

1. create dir for kext
    cd /tmp
    sudo mkdir  tempKext

2. copy kext into dir
   cd /KEXT_PROJECT_PATH/build/Release
   sudo cp -R test.kext  /tmp/tempKext

3. use PackageMaker to create install package
    (/Developer/Application/Utilities)
    drag tempKext dir into PackageMaker window
    save editing result as .pmdoc file( PackageMaker file)

4. build
    create .pkg file (install file)

share memory between app and kernel on mac os

memory allocated in the kernel cannot be written to by applications


 if a buffer must be modified by an application, the buffer must be allocated by that program, not by the kernel

mac driver debug

1. download kernel debug kit from Apple website
ex:
kernel_debug_kit_10.6.7_10j869.dmg



2.  create kext symbol file
ex:

dic->setObject("TEST_INDEX", index);
index->release();

note:
we can not modify collection directly
Following code will trigger crash
dic->setObject("testIndex", OSNumber::withNumber(200, 32));
If we want to add or delete entry in collection,
we must create new collection and  use setProperty to replace old collection
