Move target-* CPU file into a target/ folder

2016-12-20T20:52:12+00:00

We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

dump: qemunotes aren't commonly needed

2016-01-15T14:40:24+00:00

Only one of three architectures implementing qmp-dump-guest-memory write qemu notes. And, another architecture (arm/aarch64) is coming, which won't use them either. Make the common implementation truly common. (No functional change.)

dump: rebase from host-private RAMBlock offsets to guest-physical addresses

2013-08-08T15:01:46+00:00

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

s390: Implement dump-guest-memory support for target s390x

2013-07-30T14:12:25+00:00

With this patch dump-guest-memory on s390 produces an ELF formatted, crash-readable dump. In order to implement this, the arch-specific part of dump-guest-memory was added: target-s390x/arch_dump.c contains the whole set of function for writing Elf note sections of all types for s390x.
