Re: SMC for page crossing traces

Yes, it is already changes in SVN. Including few more observations that you
didn't see yet .

 

Unfortunately SVN services are not available right now for Bochs. Might be
you could look on latest SVN snapshot that Volker put on the Bochs webpage.

Subject: [Bochs-developers] SMC for page crossing traces

 

I am reading this code and wondering why the entry is not invalidated when
the second part of the trace is written into.

 

 if (mask & 0x1) {

    // the store touched 1st cache line in the page, check for

    // page split traces to invalidate.

    for (i=0;i<BX_ICACHE_PAGE_SPLIT_ENTRIES;i++) {

      if (pAddr == pageSplitIndex[i].ppf) {

        pageSplitIndex[i].ppf = BX_ICACHE_INVALID_PHY_ADDRESS;

        // SHOULD pageSplitIndex[i].e BE INVALIDATED HERE?

      }

    }

  }
