Merging vci_mem_cache from branches/v5 to trunk [441-467]

=-----------------------------------------------------------------------
r441 | cfuguet | 2013-07-17 10:54:07 +0200 (Wed, 17 Jul 2013) | 14 lines

Modifications in branches/v5/vci_mem_cache:

  • Changing name of CC DSPIN ports: + p_dspin_in => p_dspin_p2m + p_dspin_out => p_dspin_m2p
  • Splitting the Update Table in two tables: + UPT (Update Table): Stores the MULTI-UPDATE transactions + IVT (Invalidate Table): Stores the MULTI/BROADCAST INVALIDATE

transactions

Each table has its own allocator FSM: r_alloc_upt and r_alloc_ivt

=-----------------------------------------------------------------------
r442 | cfuguet | 2013-07-17 12:13:51 +0200 (Wed, 17 Jul 2013) | 13 lines

Modifications in branches/v5/modules/vci_mem_cache:

  • Introducing third port for the CLACK network.
  • CLEANUP FSM is no more a CC_SEND FSM client.
  • CLEANUP FSM controls directly the p_dspin_clack port

=-----------------------------------------------------------------------
r445 | cfuguet | 2013-07-18 10:49:36 +0200 (Thu, 18 Jul 2013) | 7 lines

Bugfix in vci_mem_cache:

  • Adding missing "strings" for print_trace() function
  • Adding alloc_ivt fsm (Invalidate Table) in the

print_trace() function

=-----------------------------------------------------------------------

Merged

/trunk/modules/vci_mem_cache:449 with
/branches/v5/modules/vci_mem_cache:446.

This merge introduces into the branch the last modifications concerning
the VCI memory cache configuration interface


Merging vci_cc_vcache_wrapper from branches/v5 to trunk [444-467]

=-----------------------------------------------------------------------
r444 | cfuguet | 2013-07-17 14:46:46 +0200 (Wed, 17 Jul 2013) | 7 lines

Modifications in branches/v5/modules/vci_cc_vcache_wrapper:

  • Renaming FROM_MC DSPIN flits fields in M2P
  • Renaming FROM_L1 DSPIN flits fields in P2M
  • Renaming CLEANUP_ACK DSPIN flits fields in CLACK

=-----------------------------------------------------------------------
r446 | cfuguet | 2013-07-18 11:37:47 +0200 (Thu, 18 Jul 2013) | 13 lines

Modifications in vci_cc_vcache_wrapper:

  • Merging the states DCACHE/ICACHE_CC_BROADCAST and DCACHE/ICACHE_CC_INVAL. This is because, the BROADCAST INVALIDATE and the MULTICAST INVALIDATE are both acknowledged by a CLEANUP.
  • Adding third port for the clack coherence network.
  • Renaming the port dspin_in to dspin_m2p and the port dspin_out to dspin_p2m

=-----------------------------------------------------------------------
r454 | haoliu | 2013-07-19 10:15:13 +0200 (Fri, 19 Jul 2013) | 2 lines

modified CC_RECEIVE FSM and CC_CHECK FSM (icache and dcache) for new
version V5

=-----------------------------------------------------------------------
r461 | cfuguet | 2013-07-19 15:49:43 +0200 (Fri, 19 Jul 2013) | 9 lines

Bugfix in vci_cc_vcache_wrapper:

  • In the states DCACHE/ICACHE CC_UPDT the FSM returns to the state CC_CHECK only when the cc_send_req is occupied.

We must not return to the CC_CHECK state if not ROK of the
DATA FIFO because the counter word counter will be reset.

=-----------------------------------------------------------------------
r462 | cfuguet | 2013-07-19 16:26:26 +0200 (Fri, 19 Jul 2013) | 8 lines

Modification in vci_cc_vcache_wrapper:

  • Optimization in DCACHE/ICACHE CC_CHECK state. We can handle a CLACK and a CC request if the latter does a MISS match. This is because the CC request doing MISS match does not need to access the directory

=-----------------------------------------------------------------------
r463 | cfuguet | 2013-07-19 16:52:06 +0200 (Fri, 19 Jul 2013) | 12 lines

Modification in vci_cc_vcache_wrapper:

  • Optimization in DCACHE/ICACHE CC_CHECK state. If pending request to CC_SEND, we wait in the CC_CHECK state. Doing this, during the wait, we can handle incoming CLACK avoiding any deadlock situation.

The states CC_UPDT and CC_INVAL do not need to test anymore if
there is a pending request to CC_SEND.


Merging tsar_generic_xbar from branches/v5 to trunk [447-467]

=-----------------------------------------------------------------------
r447 | cfuguet | 2013-07-18 16:12:05 +0200 (Thu, 18 Jul 2013) | 8 lines

Adding tsar_generic_xbar platform in branches/v5/platforms:

  • This platform contains a third local crossbar interconnect for the CLACK network.
  • It works only in a monocluster topology

=-----------------------------------------------------------------------
r448 | cfuguet | 2013-07-18 17:51:18 +0200 (Thu, 18 Jul 2013) | 9 lines

Modification in branches/v5/platforms/tsar_generic_xbar:

  • Adding a DSPIN router to the platform to allow the inter-cluster communication for the CLACK commands.

With this modification, the tsar_generic_xbar platform can be used
for multi-cluster simulations

=-----------------------------------------------------------------------
r466 | cfuguet | 2013-07-23 17:01:49 +0200 (Tue, 23 Jul 2013) | 9 lines

Modifications in branches/v5 vci_mem_cache:

  • Replacing the third router CLACK by a third virtual channel in the new virtual_dspin_router supporting several virtual channels.

The third channel has been added in the COMMAND router.

=-----------------------------------------------------------------------
r467 | cfuguet | 2013-07-23 17:23:13 +0200 (Tue, 23 Jul 2013) | 5 lines

Modifications in branches/v5 tsar_generic_xbar:

  • Adding preprocessor conditional statements for ALMOS support


Merging dspin_dhccp_param from branches/v5 to trunk [377-467]

=-----------------------------------------------------------------------
r442 | cfuguet | 2013-07-17 12:13:51 +0200 (Wed, 17 Jul 2013) | 13 lines

Modifications in branches/v5/communication/dspin_dhccp_param:

  • Renaming FROM_MC fields in M2P
  • Renaming FROM_L1 fields in P2M
  • Renaming CLEANUP_ACK fields in CLACK
