| VOID cbmiec_block_irq | ( | PDEVICE_EXTENSION | Pdx | ) |
Block all interrupts.
This function blocks all interrupt, thus that we cannot be interrupted while executing some critical things.
This should not be used for big time periods.

| VOID cbmiec_release_irq | ( | PDEVICE_EXTENSION | Pdx | ) |
Release the interrupts.
This function releases all interrupt, undoing a previous cbmiec_block_irq() call.

| VOID cbmiec_schedule_timeout | ( | IN ULONG | Howlong | ) |
Schedule a timeout.
This function schedules a timeout. Scheduling means that other threads have the opportunity to use the processor while we're waiting.
| Howlong | How long to wait (in us) |

| VOID cbmiec_udelay | ( | IN ULONG | Howlong | ) |
Wait for a timeout.
This function waits for a timeout. Waiting means that we want to have an exact timing, so don't give away the processor.
| Howlong | How long to wait (in us) |
