[Qemu-devel] [PATCH 0/3] target/ppc: add hash MMU support for the POWER9 PowerNV machine

Posted by Cédric Le Goater 6 years, 2 months ago

Hello,

This adds support for the Hash Page Table MMU mode on POWER9 PowerNV
machines. The Radix Tree mode support for the host is still to be done
but we are getting close. 

The full tree can be found here :

Thanks,

C.

  target/ppc: add basic support for PTCR on POWER9
  target/ppc: add hash MMU support on POWER9 for PowerNV only
  target/ppc: generalize check on radix when in HV mode
