<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
|
|
for drivers across platforms, and improves the chances that a driver
|
|
will "just work" on a new platform. Modifying a driver to make use
|
|
of busdma is relatively straight forward, but does require
|
|
familiarity with both the device driver and busdma primitives.
|
|
For busdma to be used in FreeBSD, two sets of changes are generally
|
|
required: adaptation of the busdma implementation to run on all
|
|
platforms, and adaptation of drivers to use the framework. As such,
|
|
status information on this project is broken down into platform
|
|
support, and driver support (sorted by category). Completing
|
|
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><b>p!=a safety</b></p>
|
|
<p>Intel PAE support requires that pointers and physical address
|
|
representations be of differing sizes. This means that drivers
|
|
must be written to use vm_paddr_t or bus_addr_t rather than
|
|
assuming that physical addresses can be represented using a
|
|
void *. In addition, format strings and casts must be
|
|
carefully handled.</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
|
|
has expressed willingness to be responsible for completing the
|
|
identified task; this doesn't preclude others working on it,
|
|
but suggests that coordination with the responsible party might
|
|
be appropriate so as to avoid unnecessary duplication of work,
|
|
and to maximize forward progress. If beginning work on a new
|
|
area of substantial size, or one that appears unclaimed, it may
|
|
be worth dropping an e-mail to &a.mux; to see if any progress
|
|
has been made.</p>
|
|
|
|
<p>The definition of the date field varies depending on the status
|
|
of a task. For completed tasks, it refers to the date completed
|
|
or reported completed. For in-progress tasks, it refers to the
|
|
date of the last update of the entry. For stalled tasks, it
|
|
refers to the date that the task was declared stalled. For
|
|
new tasks, it refers to the date the task was added to the list.</p>
|
|
|
|
<p>Tasks are sorted first by status, then by date.</p>
