This is awkward for callsites, which in practice\nall want the physical address for an arbitrary virtual address and\nhave to work around the possibility of getting a page-aligned\naddress, and it doesn't account for protection being possibly on a\nsub-page-sized granularity. We want to standardize on the\nimplementation having to handle non-page-aligned addresses.\n\nThe sparc TLB lookup code can handle non-aligned input addresses but\nwill return page-aligned results. Rather than attempting to change\nthe internals of the lookup code, we take the simple approach of\nORing the page offset back into the phys_addr result.\n\nSigned-off-by: Peter Maydell <peter.maydell@linaro.org>\nReviewed-by: Richard Henderson <richard.henderson@linaro.org>\nMessage-id: 20260417173105.1648172-5-peter.maydell@linaro.org\n---\n target/sparc/mmu_helper.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/target/sparc/mmu_helper.c b/target/sparc/mmu_helper.c\nindex a6f76a1ab7..25f8a85fae 100644\n--- a/target/sparc/mmu_helper.c\n+++ b/target/sparc/mmu_helper.c\n@@ -913,7 +913,7 @@ hwaddr sparc_cpu_get_phys_page_debug(CPUState *cs, vaddr addr)\n return -1;\n }\n }\n- return phys_addr;\n+ return phys_addr | (addr & ~TARGET_PAGE_MASK);\n }\n \n G_NORETURN void sparc_cpu_do_unaligned_access(CPUState *cs, vaddr addr,\n", "prefixes": [ "v2", "05/25" ] }
