Martin Whitaker 4078b7760e Faster barrier implementation. ... The old barrier implementation was very slow when running on a multi-socket machine (pcmemtest issue 16). The new implementation provides two options: - when blocked, spin on a thread-local flag - when blocked, execute a HLT instruction and wait for a NMI The first option might be faster, but we need to measure it to find out. A new boot command line option is provided to select between the two, with a third setting that uses a mixture of the two.		2022-02-28 22:05:21 +00:00
