Re: [lng-odp] D01 hw accelerator investigate

Sorry, there's no doc in English. SPPE is a D01's Network Processor subsystem. It has 2 Atoms(750MHz), every Atom has 8 NPU, and every NPU has 8 thread. It can deal with IPSEC packets by using crypto accelerator, can copy packets by its internal DMA engin, can fragment the packets if more than MTU

Re: [lng-odp] [ARCH DESIGN] Queues and Synchronization/Scheduling models

Ok, thanks for the clarification. I agree it makes sense for atomic queues to be implicitly released by subsequent queueing operations on buffers taken from them. But that sort of reinforces the notion that one of the pieces of buffer meta data needed is the last_queue that the buffer was on so t

Re: [lng-odp] [ODP/PATCH v3] Look ma, no barriers! C11 memory model

Hi, This patch should be split into many. It's modifying atomic API, introducing a new API (counters) as well as fixing various implementation issues (e.g. barrier). I'd prefer to define counters after v1.0 due to the fact that there are so many other APIs to be "finalize" before v1.0. Also ot

Re: [lng-odp] [ARCH DESIGN] Queues and Synchronization/Scheduling models

Bill, some spelling errors... I was listing the current calls that release the scheduling lock for a queue. * odp_queue_end() was supposed to be odp_queue_enq() (q is a d upside down, maybe I am getting dyslectic?) * odp_queue_end_multi() was of course odp_queue_enq_multi(). Not sure how this ca

Re: [lng-odp] [ARCH DESIGN] Queues and Synchronization/Scheduling models

Thanks, Ola. I need to think about this and respond more carefully, but in the meantime could you propose the syntax/semantics of odp_queue_end(), odp_queue_end_multi(), and odp_schedule_release() in a bit more detail? These seem to be new APIs and we need to be clear about their proposed semant

Re: [lng-odp] D01 hw accelerator investigate

We've discussed the notion of greater packet offload processing, permitting HW to do more direct processing of packets and protocols and having SW "fill in" as needed. I think this is an area of ODP evolution that will become increasingly important as we move forward. While our immediate focus is

[lng-odp] D01 hw accelerator investigate

Hi all, I'm investigating the D01's HW accelerators, to find out if ODP's API can cover all features. There three cases: 1. D01 has the accelerator and ODP has the API, such as the crypto. 2. ODP has but the d01 doesn't support yet. 3. The HW accelerator is a complex, it is compounded by sev
