Hi everyone, This weekend I've upgraded the machines Pernosco runs on to have Ice Lake-derived Xeon processors. This means that we can now support traces recorded with the SHA extension instructions. If you have been creating recordings of Firefox for Pernosco on a newish CPU, there are workarounds that you may have been using that are no longer required.
For everyone: - Pull the latest pernosco-submit For those with Intel processors - Remove NSS_DISABLE_HW_SHA from your environment if it is set. - Create recordings with `rr record --disable-avx512` from now on. (You were probably previously using `rr record --disable-cpuid-features-ext 0xfc230000,0x00002c42,0x0000000c`) For those with AMD processors - Remove NSS_DISABLE_HW_SHA from your environment. - Kyle -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
