6:27 a.m.
Based on review comments - I've made a few adjustments to the initial
patch. This change would be merged with 1/3 once we ensure things work
as expected.
Differences to 1/3:
1. Add "break;" in appropriate spots as found by Coverity
2. Add controller fields for :
index - Required property of <controller>
ports - Optional property of <controller>
vectors - Optional property of <controller>
queues - Optional property of optional child <driver> of <controller>
master - Optional child of <controller> with paired list of properties
address - Optional child of <controller> with paired list of properties
3. Adjust the 'cdev->id' to be "controller:" + "type" +
":" + "index" where
type, index is sourced from the <controller type='string'
index='#'>
4. Change the CIM_RES_TYPE_CONTROLLER to 32771
