[Qemu-devel] AArch64: QEMU fails in swapcontext

Hello Peter & All, I am trying to figure out a problem in qemu on aarch64 (with kvm enabled). I have found this problem in many different versions of qemu (v2.0.0-rc3/rc2/rc1/rc0, master 2d03b49), and I believe that either I am missing something common in all of these versions or its a genuine

[Qemu-devel] [PATCH 2/4] acpi-build: properly decrement objects' reference counters

[Qemu-devel] [PATCH 0/4] Fix memory leaks in QEMU

I tried running QEMU under Valgrind's Memcheck tool and managed to find some memory leaks. I only checked "definitely lost" reports. I ignored reports related to SDL/GTK because it is hard to tell if memory leak occurred in QEMU or in the library. All found errors followed one pattern: 1) Calle

[Qemu-devel] [PATCH 4/4] PortioList: fix PortioList uses so they do not leak memory

PortioList is an abstraction used for construction of MemoryRegionPortioList from MemoryRegionPortio. It is not needed later, so there is no need to allocate it dynamically. Also portio_list_destroy should be called to free memory allocated in portio_list_init. This change spans several target p

[Qemu-devel] [PATCH 3/4] graphic_console_init: do not receive unneeded error descriptions

Error set by error_set is dynamically allocated and needs to be cleared properly later. graphic_console_init neither needs error descriptions nor frees them. Pass NULL instead of actual pointers to avoid unnecessary memory allocations. Signed-off-by: Kirill Batuzov --- ui/console.c |7 ++--

[Qemu-devel] [PATCH 1/4] Replace acpi_pcihp_get_bsel with generic object_property_get_int

acpi_pcihp_get_bsel implements functionality of object_property_get_int for specific property named ACPI_PCIHP_PROP_BSEL, but fails to decrement object's reference counter properly. Replacing it with generic object_property_get_int serves two purposes: reducing code duplication and fixing memory le

Hello, Pete. You can insert tracing code into the functions from the “include\exec\softmmu_template.h” file: like helper_le_ld_name, helper_le_st_name and so on. These functions are used for CPU emulation. However, you may also need to trace DMA accesses, that are executed through other
