Hi, Current loop vectorizer uses a range of vectorization factors computed by MaxVF. For each VF, it setups unform and scalar info before building VPlan and the final best VF selection. The best VF is also selected within the VF range. for (unsigned VF = 1; VF <= MaxVF; VF *= 2) { // Collect Uniform and Scalar instructions after vectorization with VF. CM.collectUnifo...

Hello, I've been looking to the libvorbisfile and got into troubles when trying to use it: I need to compile it on a PalmOS and the libvorbisfile must be compiled in ARM whereas calling code is in 68K. This implies that the interface ov_open_callback is not usable because the OggVorbis_File *vf must point to something in the target architecture (ARM) whereas the caller cannot do that. As well as for this I need a ov_info_basic function so that no internal structure is returned (which seems to me a somewhat bad design because you'll get stuck with that: each time an internal modificat...

...ly. We have turned trust ON for host IGB driver.

Hi Laine, Thanks for taking the time to respond to my question. I think I have not described my problem clearly. Let me explain my issue below with the information that you had requested. My assumption according to the information you gave me is that the admin MAC and VF MAC are the same in my case. I see a PF (GE0-0) interface but I don’t see a vfnetdev interface as you mentioned in your email. * Given this assumption, when the host is booted, the admin MAC and VF MAC are both 00:00:00:00:00:00. [root@nfvis ~]# ip link show GE0-0 3: GE0-0: <BROADCAST,MULTICAST...

Formerly, ifcvf driver has implemented a lazy-initialization mechanism for the virtqueues and other config space contents, it would store all configurations that passed down from the userspace, then load them to the device config space upon DRIVER_OK. This can not serve live migration, so this series implement an...
