A page (even physmem) can be marked as cache-inhibited. Attempting to use 'dcbz' to zero a page mapped cache-inhibited triggers an alignment exception, which is fatal in kernel. This was seen when testing hardware acceleration with X on POWER9. At some point in the future, this should be changed to a more straight forward zero loop instead of bzero(), and a similar change be made to the other pmaps. Reported by: pkubaj@ |
