X-Git-Tag: m5_2.0_beta1~36^2~46 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4787d357d51811bf5f4c73583e038de3f60e6a72;p=gem5.git Make OzoneCPU work again in SE/FS. src/cpu/ozone/cpu.hh: Fixes to get OzoneCPU working in SE/FS again. src/cpu/ozone/cpu_impl.hh: Be sure to set up ports properly. src/cpu/ozone/front_end.hh: Allow port to be created without specifying its name at the beginning. src/cpu/ozone/front_end_impl.hh: Setup port properly, also only use checker if it's enabled. src/cpu/ozone/lw_back_end_impl.hh: Be sure to initialize variables. src/cpu/ozone/lw_lsq.hh: Handle locked flag for UP systems. src/cpu/ozone/lw_lsq_impl.hh: Initialize all variables. src/python/m5/objects/OzoneCPU.py: Fix up config. --HG-- extra : convert_revision : c99e7bf82fc0dd1099c7a82eaebd58ab6017764d --- diff --git a/src/cpu/ozone/cpu.hh b/src/cpu/ozone/cpu.hh index cacc84786..f726ac99b 100644 --- a/src/cpu/ozone/cpu.hh +++ b/src/cpu/ozone/cpu.hh @@ -214,12 +214,11 @@ class OzoneCPU : public BaseCPU uint64_t readNextNPC() { - panic("Alpha has no NextNPC!");
