<h2>Project Goal</h2>

<p><b>busdma</b></p>
|
||||
<p>The busdma interfaces permit hardware device drivers to operate
|
||||
on a variety of platforms avoiding the encoding of platform-specific
|
||||
access methods into drivers. This lowers the maintenance costs

|

this work requires a thorough audit of the system device drivers,
|
||||
then prioritized conversion of drivers.</p>
|
||||
|
||||
<p><b>INTR_MPSAFE</b></p>
|
||||
<p>Hardware drivers register their interrupt handler with the
|
||||
<code>bus_setup_intr()</code> function. Setting the flag
|
||||
<code>INTR_MPSAFE</code> tells the system interrupt code
|
||||
to call the interrupt routine without holding the Giant
|
||||
mutex. This can give a significant performance gain on SMP
|
||||
systems.</p>
|
||||
<p>Drivers can set this flag even if they are not fully locked
|
||||
down as long as their interrupt routine is careful about not
|
||||
touching other data structures in the driver. An easy way to
|
||||
do this is to check and clear the hardware interrupt status
|
||||
registers and then schedule the interrupt processing for a
|
||||
taskqueue or kernel thread.</p>
|
||||
|
||||
<p><b>SMPng locked</b></p>
|
||||
<p>Drivers should employ mutexes and sx locks to protect their
|
||||
data structures and hardware registers from competing threads.
|
||||
Mutex operations are somewhat expensive, so a good strategy is
|
||||
combine as many atomic operations into a single mutex acquisition
|
||||
as possible.</p>
|
||||
|
||||
<p>The task list below is not intended to be complete, but does
|
||||
represent a set of relevant and/or important components of the
|
||||
overall work. The "Responsible" field identifies a developer who
