**CacheRacer TODOs**
This is what remains to be done in reimplementing CacheRacer. Please
email [li.davidm96@gmail.com](mailto:li.davidm96@gmail.com) with
suggestions or questions. You can follow along with development at
https://git.lidavidm.me/cacheracer/.
## Overall
- [ ] Come up with a theme
- [ ] Overall theme
- [ ] Sneak attack/retreat =
- [ ] White walker/dragon glass =
- [ ] Arrow barrage =
## Memory
- [x] Make sure `ReverseMmu` maps addresses correctly (i.e. 0x0 should
map to an actual array element)
- [ ] `ReverseMmu` needs to mark VA 0x0 as invalid somehow
- [x] Sneak attack/retreat needs to be per-core
- [x] ~~Invalidate~~/update other caches when a write is made
- [ ] Implement global data structures
- [ ] Player status
- [ ] Core status
- [ ] Cache info
- [ ] Enemy memory should be inaccessible unless in sneak-attack mode
## Scoring
- [ ] Stop game once score reached
- [ ] Provide visualization (possibly using console?) like one used at
tournament
## Sneak Attack/Retreat
- [ ] Test sneak attack/retreat system calls
- [ ] Implement taunt array
- [ ] Write array to main memory
- [ ] Update or invalidate relevant cache lines
## Traps
- [ ] Implement traps
- [x] Write traps ("White Walkers" in Fall 2015)
- [ ] Area traps ("Arrow Barrages" in Fall 2015)
- [ ] Rebalance traps
- [ ] Anti-write traps ("Dragon Glass" in Fall 2015)
## Development/Debugging
- [ ] Write the header file
- [x] Write some sample bots
- [x] Publish them
- [ ] Package RISC-V toolchain
- [ ] Find way to shrink toolchain
- [ ] Implement debugger
- [ ] Debug logging
- [ ] Cache misses/stalls
- [ ] Traps
## Misc
- [ ] Allow custom trap handling in simulator, so we can restart cores
if they crash
