Re: [Gems-users] problem with CMP and tester.exec

[Luke Yen <lyen@xxxxxxxxxxx>]

   There are some missing u_writeDataToL1Cache actions in the 
current MESI_CMP_filter_directory-L1cache.sm file.  They should be added 
whenever the L1 receives data from the L2 or L1.  Here's a list of 
transitions that need this action:
transition(IS, L2_Data_all_Acks, S) {
    u_writeDataToL1Cache;
    ...

 transition(IS_I, L2_Data_all_Acks, S) {
    u_writeDataToL1Cache;
   ...

 transition({IS, IS_I}, L2_Data, IS_S) {
    u_writeDataToL1Cache;
    ...

transition({IS, IS_I}, L2_Exclusive_Data, IS_E) {
    u_writeDataToL1Cache;
   ...

  transition({IS, IS_I}, L2_Exclusive_Data_all_Acks, E){
    u_writeDataToL1Cache;
    ...

  transition(IS, DataS_fromL1, S) {
    u_writeDataToL1Cache;
   ...

 transition(IS_I, DataS_fromL1, S) {
    u_writeDataToL1Cache;
   ...

  transition(IM, Data_all_Acks, M) {
    u_writeDataToL1Cache;
   ...

 transition(IM, L2_Data, IM_M) {
    u_writeDataToL1Cache;
    ...

  transition(IM, L2_Data_all_Acks, M){
    u_writeDataToL1Cache;
   ...

   Even with these fixes, this protocol can still fail the tester due to 
complex PUTX races that we are currently debugging & fixing.  The next 
version of this protocol will be coming out with GEMS 2.1, once we get all 
its features tested & debugged.
