Making driver interruptable

- Subject: [ECOS] Making driver interruptable
- Bcc:
Are the device drivers any different from any functions called by a thread
currently running? I mean, eg. a thread calls I/O API cyg_io_write() which
in turn passes the control to device driver routines. If now another thread
with higher priority becomes runnable, will the execution of driver routines
be halted to let the higher priority thread run?
In this regard, I see the driver no different from any other functions
called by the thread. Any comments???
