From 56c4bfb3f07f3107894c00281276aea4f5e8834d Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Tue, 6 Aug 2013 12:37:11 +0200 Subject: dump: rebase from host-private RAMBlock offsets to guest-physical addresses RAMBlock.offset --> GuestPhysBlock.target_start RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end RAMBlock.length --> GuestPhysBlock.target_end - GuestPhysBlock.target_start "GuestPhysBlock.host_addr" is only used when writing the dump contents. This patch enables "crash" to work with the vmcore by rebasing the vmcore from the left side of the following diagram to the right side: host-private offset relative to ram_addr RAMBlock guest-visible paddrs 0 +-------------------+.....+-------------------+ 0 | ^ | | ^ | | 640 KB | | 640 KB | | v | | v | 0x0000a0000 +-------------------+.....+-------------------+ 0x0000a0000 | ^ | |XXXXXXXXXXXXXXXXXXX| | 384 KB | |XXXXXXXXXXXXXXXXXXX| | v | |XXXXXXXXXXXXXXXXXXX| 0x000100000 +-------------------+.....+-------------------+ 0x000100000 | ^ | | ^ | | 3583 MB | | 3583 MB | | v | | v | 0x0e0000000 +-------------------+.....+-------------------+ 0x0e0000000 | ^ |. |XXXXXXXXXXXXXXXXXXX| | above_4g_mem_size | . |XXXX PCI hole XXXXX| | v | . |XXXX XXXXX| ram_size +-------------------+ . |XXXX 512 MB XXXXX| . .|XXXXXXXXXXXXXXXXXXX| . +-------------------+ 0x100000000 . | ^ | . | above_4g_mem_size | .| v | +-------------------+ ram_size + 512 MB Related RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=981582 Signed-off-by: Laszlo Ersek Signed-off-by: Luiz Capitulino --- include/sysemu/memory_mapping.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'include/sysemu/memory_mapping.h') diff --git a/include/sysemu/memory_mapping.h b/include/sysemu/memory_mapping.h index b2d7d850c1..a75d59a55d 100644 --- a/include/sysemu/memory_mapping.h +++ b/include/sysemu/memory_mapping.h @@ -68,10 +68,13 @@ void guest_phys_blocks_free(GuestPhysBlockList *list); void guest_phys_blocks_init(GuestPhysBlockList *list); void guest_phys_blocks_append(GuestPhysBlockList *list); -void qemu_get_guest_memory_mapping(MemoryMappingList *list, Error **errp); +void qemu_get_guest_memory_mapping(MemoryMappingList *list, + const GuestPhysBlockList *guest_phys_blocks, + Error **errp); /* get guest's memory mapping without do paging(virtual address is 0). */ -void qemu_get_guest_simple_memory_mapping(MemoryMappingList *list); +void qemu_get_guest_simple_memory_mapping(MemoryMappingList *list, + const GuestPhysBlockList *guest_phys_blocks); void memory_mapping_filter(MemoryMappingList *list, int64_t begin, int64_t length); -- cgit 1.4.1
