P9 supports PCI tunneled operations (atomics and as_notify). This patch adds support for tunneled operations on powernv, by adding a new API to be called by drivers: pnv_pci_get_tunnel_ind() -- tell driver the 16-bit ASN indication set by kernel. pnv_pci_set_tunnel_bar() -- tell kernel the Tunnel BAR address mask used by driver. These functions use four new OPAL calls, as PBCQ and PHB configurations are done by skiboot. Signed-off-by: Philippe Bergheaud <fe...@linux.vnet.ibm.com> --- This patch depends on the following skiboot prerequisites: https://patchwork.ozlabs.org/patch/829294/ [1/2] phb4: set PHB CMPM registers for tunneled operations https://patchwork.ozlabs.org/patch/829293/ [2/2] phb4: set PBCQ Tunnel BAR for tunneled operations
Looks good for me. Acked-by: Christophe Lombard<clomb...@linux.vnet.ibm.com> Thanks
