| # This is a very special patch -- it allows us to build kernels on SGI IP28 |
| # (Indigo2 Impact R10000) systems. |
| # Unless you're building an IP28 kernel, you really don't need care about what |
| # this patch does, because if you are, you are probably already aware of what |
| # it does. |
| # All that said, the abilities of this patch are disabled by default and need |
| # to be enabled by passing -mr10k-cache-barrier. |
| # The option also accepts a flag, which are highlighted below: |
| # -mr10k-cache-barrier=1 - Protect stores only (IP28) |
| # -mr10k-cache-barrier=2 - Protect stores and loads (IP32 R10K) |
