DEXT. How to set property for SCSI device created by UserCreateTargetForId()

Question

For my KEXT I set the property “Protocol Characteristics” in Info.plist file

<key>Protocol Characteristics</key>
<dict>
    <key>Physical Interconnect</key>
    <string>SAS</string>
    <key>Physical Interconnect Location</key>
    <string>External</string>
</dict>

For DEXT this method does not work - still my SCSI device has “Internal/External” property instead of “External” Protocol Characteristics

<dict>
    <key>Physical Interconnect</key>
    <string>SCSI Parallel Interface</string>
    <key>Physical Interconnect Location</key>
    <string>Internal/External</string>
</dict>

I also tried to set these properties by the second parameter for UserCreateTargetForId(). It also did not work.

Does anybody know how to set the property?

Answer 1

I assume this is for a dext implementing IOUserSCSIParallelInterfaceController?

I've not tested it myself, but have you tried calling UserSetTargetProperties() in your controller?

Answer 2

Update OS to current state and setup properties by using 'Info.plist' has worked correct for me.
