Get PID of a domain's QEMU instance from its domain ID
...cannot find a way to retrieve PIDs of QEMU instances from libvirt domains' IDs (I'm using libvirt C API). I recognize it sounds like a bad idea doing so (and I know PIDs are explicitly made not available, as I gathered from the source code and on your IRC channel) but I need that to use the perf_event_open syscall in order to gather statistics on my QEMU/KVM guests. I also know libvirt now supports some perf events but only a few and I need more. I could submit patches to add them and I will definitely consider that but in the meantime... What would be the best way to get those PIDs? I tried using t...

[PATCH 0/2] adding tracepoints to vhost
To help in vhost analyzing, the following series adding basic tracepoints to vhost. Operations of both virtqueues and vhost works were traced in current implementation, net code were untouched. A top-like satistics displaying script were introduced to help the troubleshooting. TODO: - net specific tracepoints? --- Jason Wang (2): vhost: basic tracepoints tools: virtio: add a

[PATCH 0/6] drm: Provide a simple encoder
Many DRM drivers implement an encoder with an empty implementation. This patchset adds drm_simple_encoder_init() and drm_simple_encoder_create(), which can be used by drivers instead. Except for the destroy callback, the simple encoder's implementation is empty. The patchset also converts 4 encoder instances to use the simple-encoder helpers. But there are at least 11 other drivers which can
