Hi Folks, </div>
<div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">

<div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">
I was wondering whether anyone in this list had success passing
through the GPU via OVMF with linux-4.3.1 or linux-4.2.7? The changelog [1] [2] stated that the
patch for slowness boot (decompression, 100% CPU usage) [3] is already applied. In my case I’m still experiencing the slowness and 100% CPU usage on one of my threads (Intel Core i7-5820K + ASUS X99-A), so I’m still on linux-lts-4.1.14.</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">I had this hypothesis that the patch [3] only applies on non LGA 2011/LGA 2001-v3 platform, since I had success patching it manually from linux-4.3-mainline [4] on my previous Haswell platform (Intel Core i7-4770 + ASRock Z87 Extreme6).</div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;"><br></div><div id="bloop_customfont" style="font-family:Helvetica,Arial;font-size:13px; color: rgba(0,0,0,1.0); margin: 0px; line-height: auto;">I hope my hypothesis is wrong. If anyone had success, please let me know your platform. Thanks.</div>
