Rahul Garg a1d401336b Addition of hipCtxEnablePeerAccess and hipCtxDisablePeerAccess functions 
Change-Id: I381c8cbbde17eae7d9bb5d4cb1596cebf4bda039
 2016-08-26 13:51:33 +05:30
Ben Sander f19f2248bf Add initial context implementation. 
APIs: hipInit, hipCtxCreate.
Track TLS default ctx.  Set deviceID now changes the ctx.
Add first context test.

Ben Sander d09b19bb6c Split ihipCtx_t into ihipCtx_t and ihipDevice_t . 
Major change to existing code base.
    Ctx holds streams, enables peers, and flags.
    Device holds accelerator, hsa-agent, device props.

Add hipCtx_t.

Add peer APIs that accept hipCtx_t (in addition to deviceId)

Compiles and passes directed tests.

Ben Sander 4e0a1e1869 fix direction of peer enable/disable APIs 
- Enable(peerId) makes memory physically located on peer visible to
current device.

Ben Sander c3bd85595d P2P Update. 
- add P2P staging buffer copy.
- If copy device does not have sufficient access permissions, fall back
  to staging buffer.
- improve docs for which copy device is used.

Ben Sander efffb0ed86 Clean up disable. 
Add USE_HCC_LOCK (disabled)
Disable USE_PEER_TO_PEER.
 2016-04-11 09:09:36 -05:00
Ben Sander 9e7efd7c65 P2p checkpoint. 
- set USE_PEER_TO_PEER=3 (requires HCC "am_memtracker_update_peers")
- when enabling peer, turn it on for previously allocated memory.
- hipDeviceCanAccessPeer is no longer self-ware (self does not qualify
  as a peer)
- device peerlist always includes self, so when we call allow_access
  we never remove self access.
- hipDeviceReset() removes old peer mappings.

Ben Sander a4d97c3172 Remove stray debug msgs, hipInfo don't print self as peer. 2016-04-11 07:58:58 -05:00
Ben Sander 173cff4c1e fix bugs in P2P implementation 
- addPeers polarity reversed, would never add.
- check allow_access return value, pipe error to hipMalloc.

Ben Sander 52ac414b40 Use HCC get_is_pool, add USE_PEER_TO_PEER level 2, 3. 2016-04-11 07:58:58 -05:00
Ben Sander 97772d6363 For P2P, use the peer list when allocating Device memory or pinned host. 
Each new allocation is automatically mapped into the address space of
all enabled peers.

Ben Sander e2d19d7f7a P2P checkpoint. 
Maintain enabled peer tables for each device.
