In HPT mode on POWER9, the ASDR register is supposed to record segment information for hypervisor page faults. It turns out that POWER9 DD1 does not record the page size information in the ASDR for faults in guest real mode. We have the necessary information in memory already, so by moving the checks for real mode that already existed, we can use the in-memory copy. Since a load is likely to be faster than reading an SPR, we do this unconditionally (not just for POWER9 DD1). Signed-off-by: Paul Mackerras <paulus@ozlabs.org> |
