2013-06-17dump: qmp_dump_guest_memory(): use error_setg_file_open()Luiz Capitulino1-1/+1
Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Kevin Wolf <kwolf@redhat.com>
2013-06-11memory_mapping: Improve qemu_get_guest_memory_mapping() error reportingAndreas Färber1-1/+6
Pass any Error out into dump_init() and have it actually stop on errors. Whether it is unsupported on a certain CPU can be checked by looking for a NULL CPUClass::get_memory_mapping field. Reviewed-by: Luiz Capitulino <lcapitulino@redhat.com> [AF: Reverted changes to CPU loops] Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-06-11dump: Abstract dump_init() with cpu_synchronize_all_states()Andreas Färber1-2/+3
Instead of calling cpu_synchronize_state() for each CPU, call the existing cpu_synchronize_all_states() helper. Reviewed-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-05-01cpu: Move cpu_write_elfXX_note() functions to CPUStateJens Freimann1-4/+4
Convert cpu_write_elfXX_note() functions to CPUClass methods and pass CPUState as argument. Update target-i386 accordingly.

2013-04-15include: avoid useless includes of exec/ headersPaolo Bonzini1-1/+5
Headers in include/exec/ are for the deepest innards of QEMU, they should almost never be included directly. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Change gdbstub's cpu_index() argument to CPUState now that CPUArchState is no longer used. Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-9/+9
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-09-27qmp: dump-guest-memory: don't spin if non-blocking fd would blockLuiz Capitulino1-11/+4
fd_write_vmcore() will indefinitely spin for a non-blocking file-descriptor that would block. However, if the fd is non-blocking, how does it make sense to spin? Change this behavior to return an error instead. Note that this can only happen with an fd provided by a management application. The fd opened internally by dump-guest-memory is blocking. While there, also fix 'writen_size' variable name.

2012-06-09w32: Fix broken build (missing include file)Stefan Weil1-4/+0
dump.c was recently added to the code. It unconditionally includes sys/procfs which is not available with MinGW (w32, w64). It looks like this file is not needed at all (tested on Linux), so I removed it completely. Some other include statements are also redundant because they are already included in qemu-common, therefore they were removed, too.

2012-06-07dump: remove dumping stuff from cpu-all.hPaolo Bonzini1-11/+0
This simplifies things, because they will only be included for softmmu targets and because the stubs are taken out-of-line in separate files, which in the future could even be compiled only once. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-07dump: change cpu_get_note_size to return ssize_tPaolo Bonzini1-2/+7
So that it can use the same prototype in both cases. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-06-04introduce a new monitor command 'dump-guest-memory' to dump guest's memoryWen Congyang1-0/+883
The command's usage: dump-guest-memory [-p] protocol [begin] [length] The supported protocol can be file or fd: 1. file: the protocol starts with "file:", and the following string is the file's path. 2. fd: the protocol starts with "fd:", and the following string is the fd's name. Note: 1. If you want to use gdb to process the core, please specify -p option. The reason why the -p option is not default is: a. guest machine in a catastrophic state can have corrupted memory, which we cannot trust. b. The guest machine can be in read-mode even if paging is enabled. For example: the guest machine uses ACPI to sleep, and ACPI sleep state goes in real-mode. 2. If you don't want to dump all guest's memory, please specify the start physical address and the length.
