December 10, 20169 yr Hello, Ive got the latest ASRock J4205-ITX mainboard, as i wanted to build NAS/HTPC after many days of trying multiple things ive find out that even the CPU supports VT-D (IOMMU) (http://www.technikaffe.de/cpu-intel_pentium_j4205-661?) - is not possible to turn it on in BIOS So the result is that i cant passthrough Graphics Card into VM I was trying to setup unRAID ( ) --- Im curious how is it on older models like J3710 or N3700 ASrock boards? please can u check and let me know? Thanks
December 11, 20169 yr ... after many days of trying multiple things ive find out that even the CPU supports VT-D (IOMMU) No reason to spend days trying to determine a CPU's characteristics => just go to Intel's Ark site for any Intel CPU ... https://ark.intel.com/products/95591/Intel-Pentium-Processor-J4205-2M-Cache-up-to-2_6-GHz As you've noted, the CPU does support vt-d Look VERY carefully in the motherboard's BIOS to see if there is an option to turn this feature on/off. With an embedded CPU, I'd certainly expect that they DO support the features it supports ... but it is possible that they don't. These options are often very hard to find with all the option pages in a modern BIOS.
December 11, 20169 yr Author i did check the CPU specs (after i placed the MB order) Guys in video has also ASROCK with UEFI , but more "advance" model - have no such option in Bios. I did ask the ASROCK support also - waiting for the reply, but i wanted also ask if other users with such AIO boards have the same problem.
January 27, 20179 yr The option to enable VT-d is now present in official bios 1.20 -> http://www.asrock.com/mb/Intel/J4205-ITX/index.us.asp?cat=Download&os=BIOS Don't get your hopes up, iGPU passthrough is not working properly, I would think qemu doesn't completely support the SoC, so far no answer from Limitech, I think they just don't have the hw to test this on. https://lime-technology.com/forum/index.php?topic=54915
January 27, 20179 yr Author i did update bios from UEFI - but in 11% got frozen for like 30m so i had to reset, of course MB didnt boot up, so i had to send it to warranty replace anyway thanks for the other "great" info Seems like i never build my all in one device ...
