I dug some more and found another way to print data in DRAM. struct StoreBufferEntry has a function, write_to_ram(). write_to_ram() calls storemask_virt(). It seems like I could: -Check there's no pagefault for the virtual address passed to storemask_virt() -Call loadvirt() within storemask_virt() to get the old data in DRAM -Save the new data passed to storemask_virt() -Use paddr calculated in storemask_virt() as the physical address -If the CHECK_STORE logic fails, and store doesn't match, don't log -If no problems, print out the address (paddr), old data and new data to file. Does anyone see any problems with this approach? _______________________________________________ http://www.marss86.org Marss86-Devel mailing list [email protected] https://www.cs.binghamton.edu/mailman/listinfo/marss86-devel
