[RFC 00/10] Freescale DPAA B/QMan drivers

2015-02-04 Thread Emil Medve 

Hello,


This is the first attempt to publish the Freescale DPAA B/QMan drivers. They are
not to be applied yet.  At this stage, this is more or less the drivers from the
Freescale PowerPC SDK roughly squashed and split in a sequence of component
patches. They still needs some work and cleanup before we expect to have them
applied, but we appreciate early feedback


Cheers,


Geoff Thorpe (8):

Will get both lists, say, for the next post

These files contain the public interface(s) used by other devices
connected to the B/QMan: FMan, PME, RMan, DCE, etc. Every driver/piece
of code in need of a HW queue (QMan) or HW buffer allocator (BMan) will
use these files

Hello Dan,


Thanks for the reply

I think I'll go for drivers/soc as we have quite a handful of other
drivers using this code that already decided not to be located into staging

Let me inquire with the FMan guy here. I'll get back to you on this,
however, don't hold your breath. There might be some weeks before the
FMan driver will hit the e-mail lists

These drivers (with some upcoming updates) are expected to be use on all
QorIQ and LS1 devices. The programming model for LS2 (which includes the
AIOP and friends) seems to have a different programming model and these
drivers will not be usable there
