|
44 * We need this class to derive from DLogicalChannel rather than DLogicalChannelBase |
|
45 * This is for several reasons: |
|
46 * We are making calls that take a long time, which means we don't want the |
|
47 * user side thread to block while doing this, and we don't want to be interrupted |
|
48 * and loose our state. So we solve this by running the device driver as |
|
49 * as it's own separate thread in the kernel (DLogicalChannelBase runs a user thread in kernel mode, |
|
50 * DLogicalChannel runs a kernel thread called from a user thread). |
|
51 * We also solve the long timing issue by making an asynchrounous call by using the DoRequest call. |
|
52 * For this to work we need to create a DfcQ, i.e. a queue of all the incoming calls from the user side. |
|
53 * These then get's run in turn. |
