| Subject: arm64: Kconfig: Make ARM64_PSEUDO_NMI depend on BROKEN for now |
| |
| From: Will Deacon <will.deacon@arm.com> |
| |
| commit 96a13f57b946be7a6c10405e4bd780c0b6b6fe63 upstream. |
| |
| Although we merged support for pseudo-nmi using interrupt priority |
| masking in 5.1, we've since uncovered a number of non-trivial issues |
| with the implementation. Although there are patches pending to address |
| these problems, we're facing issues that prevent us from merging them at |
| this current time: |

| |
| For now, simply mark this optional feature as BROKEN in the hope that we |
| can fix things properly in the near future. |
