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\nFor alpha, the get_physical_address() function accepts arbitrary\ninput addresses but may return an output rounded down to a page\nboundary, so in alpha_cpu_get_phys_page_debug() we OR the within-page\noffset into it before returning it.\n\nSigned-off-by: Peter Maydell <peter.maydell@linaro.org>\n---\n target/alpha/helper.c | 1 +\n 1 file changed, 1 insertion(+)", "diff": "diff --git a/target/alpha/helper.c b/target/alpha/helper.c\nindex 179dc2dc7a..af6d7847d5 100644\n--- a/target/alpha/helper.c\n+++ b/target/alpha/helper.c\n@@ -301,6 +301,7 @@ hwaddr alpha_cpu_get_phys_page_debug(CPUState *cs, vaddr addr)\n int prot, fail;\n \n fail = get_physical_address(cpu_env(cs), addr, 0, 0, &phys, &prot);\n+ phys |= addr & ~TARGET_PAGE_MASK;\n return (fail >= 0 ? -1 : phys);\n }\n \n", "prefixes": [ "02/17" ] }
