I'm trying to understand the paravirtualization interface between the OS and Xen. Here is one thing that's confusing me-- In Linux, the xen probe() routine calls hpte_init_lpar() which hooks up some pseries hypervisor MMU routines. These translate into a plpar_hcall_norets() invocation, but using pSeries hypervisor opcodes (e.g. H_PUT_TCE). Related to that I don't see the mmu_update hypercall used in Linux. How do the MMU related hypercalls work?
We kept all the MMU and IOMMU related hcalls from PAPR, so the pSeries LPAR paths are jsut fine for us.
The PAPR is availble from the power.org website. -JX _______________________________________________ Xen-ppc-devel mailing list Xen-ppc-devel@lists.xensource.com http://lists.xensource.com/xen-ppc-devel
