From: Bharat Bhushan <bharat.bhushan@xxxxxxxxxxxxx> kvm: powerpc: use cache attributes from linux pte First patch is moving functions/logic in common code so they can be used on booke also. Second and Third patch is actually setting caching attributes (TLB.WIMGE) using corresponding Linux pte. v5-v6 - First three patches are already applied from this patchset, so sending ramining patches - return NULL rather than _pte(0) from lookup_linux_pte() and checking for NULL in caller v3->v5 - Fix tlb-reference-flag clearing issue (patch 4/6) - There was a patch (4/6 powerpc: move linux pte/hugepte search to more generic file) in the last series of this patchset which was moving pte/hugepte search functions to generic file. That patch is no more needed as some other patch is already applied to fix that :) v2->v3 - now lookup_linux_pte() only have pte search logic and it does not set any access flags in pte. There is already a function for setting access flag which will be called explicitly where needed. On booke we only need to search for pte to get WIMG. v1->v2 - Earlier caching attributes (WIMGE) were set based of page is RAM or not But now we get these attributes from corresponding Linux PTE. *** BLURB HERE *** Bharat Bhushan (3): kvm: powerpc: keep only pte search logic in lookup_linux_pte kvm: booke: clear host tlb reference flag on guest tlb invalidation kvm: powerpc: use caching attributes as per linux pte arch/powerpc/include/asm/kvm_host.h | 2 +- arch/powerpc/include/asm/pgtable.h | 24 +++++++++++++++ arch/powerpc/kvm/book3s_hv_rm_mmu.c | 36 ++++++++--------------- arch/powerpc/kvm/booke.c | 2 +- arch/powerpc/kvm/e500.h | 8 +++-- arch/powerpc/kvm/e500_mmu_host.c | 54 +++++++++++++++++++--------------- 6 files changed, 73 insertions(+), 53 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
