2016-12-20Move target-* CPU file into a target/ folderThomas Huth
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.

2016-08-10ppc64: fix compressed dump with pseries kernelLaurent Vivier
If we don't provide the page size in target-ppc:cpu_get_dump_info(), the default one (TARGET_PAGE_SIZE, 4KB) is used to create the compressed dump. It works fine with Macintosh, but not with pseries as the kernel default page size is 64KB. Without this patch, if we generate a compressed dump in the QEMU monitor: (qemu) dump-guest-memory -z qemu.dump This dump cannot be read by crash: # crash vmlinux qemu.dump ... WARNING: cannot translate vmemmap kernel virtual addresses: commands requiring page structure contents will fail ... Page_size is used to determine the dumpfile's block size. The block size needs to be at least the page size, but a multiple of page size works fine too. For PPC64, linux supports either 4KB or 64KB software page size. So we define the page_size to 64KB.

2016-01-15dump: qemunotes aren't commonly neededAndrew Jones
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.)

2014-06-16target-ppc: Support dump for little endian ppc64Bharata B Rao
Fix ppc64 arch specific dump code to support all combinations of little/big endian hosts/guests. FWIW the current code is broken for altivec registers when guest and host have a different endianness: these 128-bit registers are written to guest memory as a two 64-bit entities and we should also swap them. Unit testing was done with the following program provided by Tom Musta: #include <stdio.h> #include <stdint.h> #include <stdlib.h> int main(int argc, char** argv) { __uint128_t v = ((__uint128_t)0x0001020304050607ull << 64) | 0x08090a0b0c0d0e0full; register void * vptr asm ("r11"); vptr = &v; for(;;) asm volatile ("lvx 30,0,11" ); } When sending SIGABRT to this program and examining the core file, we get: - ppc64 : 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f - ppc64le: 0f 0e 0d 0c 0b 0a 09 08 07 06 05 04 03 02 01 00 We expect to find the very same layout in the QEMU dump since they are real core files. This is what we get: - ppc64 host, ppc64 guest : 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f - ppc64 host, ppc64le guest : 0f 0e 0d 0c 0b 0a 09 08 07 06 05 04 03 02 01 00 - x86_64 host, ppc64 guest : 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f - x86_64 host, ppc64le guest: 0f 0e 0d 0c 0b 0a 09 08 07 06 05 04 03 02 01 00 We introduce a NoteFuncArg type to avoid adding extra arguments to all note functions.
