This patch set is continuous MMU enhancement, it is focused on TLB search, especially on function helper_invtlb_page_asid() and function helper_invtlb_page_asid_or_g(). The code is similiar with function loongarch_tlb_search(), one common API loongarch_tlb_search_cb() is added for these functions.
Also there is optimization with qemu TLB flush, invalidate_tlb_entry() is used to flush one TLB entry rather than flush all TLB entries. This patchset is based on patch sent at https://lore.kernel.org/qemu-devel/20250730030202.3425934-1-maob...@loongson.cn/ --- v1 ... v2: 1. Add bugfix patch with CSR_STLBPS page size set issue. 2. Add tlb entry invalidation in function invalidate_tlb(), it can be used in both helper_invtlb_page_asid() and function helper_invtlb_page_asid_or_g(). --- Bibo Mao (8): target/loongarch: Fix page size set issue with CSR_STLBPS target/loongarch: Add tlb search callback in loongarch_tlb_search() target/loongarch: Add common API loongarch_tlb_search_cb() target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid_or_g target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid target/loongarch: Invalid tlb entry in invalidate_tlb() target/loongarch: Only flush one TLB entry in helper_invtlb_page_asid_or_g() target/loongarch: Only flush one TLB entry in helper_invtlb_page_asid() target/loongarch/tcg/csr_helper.c | 2 +- target/loongarch/tcg/tlb_helper.c | 109 +++++++++++++++--------------- 2 files changed, 57 insertions(+), 54 deletions(-) base-commit: 51604337790aacfd22770b7996c99ed7b5c085c5 -- 2.39.3
