From 574d96933ceff60b2d13fe97602572fc7e95f7c6 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Fri, 12 Apr 2019 16:26:52 +0100 Subject: hmp: gva2gpa debug command Add a gva2gpa command purely for debug which performs address translation on the gva, the existing gpa2hva command can then also be used to find it in the qemu userspace; e.g. (qemu) info registers .... RSP=ffffffff81c03e98 .... (qemu) gva2gpa 0xffffffff81c03e98 gpa: 0x1c03e98 (qemu) gpa2hva 0x1c03e98 Host virtual address for 0x1c03e98 (pc.ram) is 0x7f0599a03e98 (qemu) x/10x 0xffffffff81c03e98 ffffffff81c03e98: 0x81c03eb8 0xffffffff 0x8101ea3f 0xffffffff ffffffff81c03ea8: 0x81d27b00 0xffffffff 0x00000000 0x00000000 ffffffff81c03eb8: 0x81c03ec8 0xffffffff gdb -p ...qemu...
