| H A D | fu_pool.hh | diff 9444:ab47fe7f03f0 Mon Jan 07 13:05:00 EST 2013 Andreas Sandberg <Andreas.Sandberg@ARM.com> cpu: Rewrite O3 draining to avoid stopping in microcode Previously, the O3 CPU could stop in the middle of a microcode sequence. This patch makes sure that the pipeline stops when it has committed a normal instruction or exited from a microcode sequence. Additionally, it makes sure that the pipeline has no instructions in flight when it is drained, which should make draining more robust. Draining is controlled in the commit stage, which checks if the next PC after a committed instruction is in microcode. If this isn't the case, it requests a squash of all instructions after that the instruction that just committed and immediately signals a drain stall to the fetch stage. The CPU then continues to execute until the pipeline and all associated buffers are empty. |
