[Crash-utility] [External Mail][营销邮件] Re: ramdump support for va_bits_actual

[赵乾利]

Hi,Vinayakm

I don't think it's necessary to judge physvirt_offset if empty in arm64_VTOP,because physvirt_offset always be initialized by arm64_calc_physvirt_offset,so machdep->machspec->physvirt_offset always true.even if older kernel are compatible.

so,how about the following change?

@@ -1148,8 +1155,7 @@ arm64_VTOP(ulong addr)
                }

                if (addr >= machdep->machspec->page_offset)
-                       return machdep->machspec->phys_offset
-                               + (addr - machdep->machspec->page_offset);
+                       return (addr + machdep->machspec->physvirt_offset);

Hi Dave, zhaoqianli

I have picked up the vmemmap_start as 4th patch. The physvirt_offset
based VTOP is already
part of patchset 1. I hope I have not missed anything from those
recommended by Zhaogianli.

PFA.
