Subject: [PATCH] 0/2 Add support for maple "Visual Memory Unit" on SEGA
Date: Tue, 18 Mar 2008 22:30:13 +0000	[thread overview]
Message-ID: <1205879413.6250.13.camel@localhost.localdomain> (raw)

The VMU is a small (approx 128K) hotpluggable flash device on the SEGA Dreamcast.

To get this to work I have had to rewrite parts of the maple bus driver - some of that
is bug fixing (in the sense that the bus driver was not allowing proper probing, just
forcing the load of the appropriate driver) - the main functional change is to add a
semaphore to the maple device (to ensure that devices can properly inject maple packets
into the queue of packets waiting to be dispatched via DMA to the devices themselves).
