Author	SHA1	Message	Date
davidmetz	efc32d0cab	Fix CPI calcualtion for -s option (#192) This attempt at rounding leads to wrong results, for example: 314689951 cycles 314690101 instructions 0.90 CPI With my change results in: 314689951 cycles 314690101 instructions 0.99 CPI I think this was supposed to be part of rounding behaviour but it doesn't work if only the final digit does it and there is no carry... Instead I changed it to truncate after the second digit	6 years ago

Palmer Dabbelt	9204785053	Detect harts that can't boot Linux instead of hard-coding them This checks to see if a hart can't boot Linux by looking for a compatible "mmu-type" field. If the hart can't boot Linux, then bbl masks it off.	9 years ago

Palmer Dabbelt	9037b1d9f2	Add a platform interface SiFive's pk fork is the second one I've had to maintain, and it's a huge pain because people keep just leaving changes all over the tree. I want to introduce an interface that the platform-specific details can live behind so I don't have to keep doing these painful merges.	9 years ago
