Dell Presicion T7600 and iommu support
I have the above mentioned workstation and I like to know if it supports iommu or Intel VT-d equivalent and which bios feature proves that.
Being trying to contact Dell but no lack since I cant find a support email. Anyone with the same pc knows that info? I am on A16 Bios Ver.
Ps Some interesting bios options I found in case they help are
Security->TPM Security (Trusted Module Platform)->Disabled
CPU XD Support (The operating system can use this feature to hinder software that exploits buffer overflows)->Enabled
VT for Direct I/O->enabled
PCI MMIO Space Size->Large
PCI Bus Configuration->64 Pci Buses (Also has 128 and 256 to choose from
Thank you in advance
Based on a paragraph I ve read about c600 chipset (T7600 uses that)
Intel® Virtualization Technology for Directed I/O (Intel® VT-d) (Not available on HEDT SKU)The PCH provides hardware support for implementation of Intel® Virtualization Technology with Directed I/O (Intel® VT-d). Intel® VT-d consists of technology components that support the virtualization of platforms based on Intel® Architecture Processors. Intel® VT-d 5 technology enables multiple operating systems and applications to run in independent partitions. A partition behaves like a virtual machine (VM) and provides isolation and protection across partitions. Each partition is allocated its own subset of host physical memory.
Latest bios seems to have that option for Virtualization Technology for Directed I/O which is the same as vt-d (which is an extension of the vt-x) Then again it mentions Not available on HEDT SKU Is the Dell T7600 part of HEDT SKU.
Few paragraphs below I am reading again
Technologies supported—Intel® I/O Virtualization (VT-d) Support (SRV/WS SKUs Only) If WS stands for work station Dell T7600 is one.
Throughout this document, the terms “Server/Workstation” and “Server/Workstation” Only” refer to information that is applicable only to the Intel® C602 Chipset, Intel®C602J Chipset, Intel® C604 Chipset, Intel® C606 Chipset, and Intel® C608 Chipset, unless specifically noted otherwise. Server/Workstation is abbreviated SRV/WS
...excludes c600 chipset
And finally this. I think is too confusing all this info. Is the c600 chipset same as x79 and doesnt support vt-d (if yes then why in bios there is the VT for Direct I/O option avaliable) or is it different?
