How to use the rdrand engine in OpenSSL for random number generation
Par John Mechalas (Intel)Publié le 07/30/20140
The OpenSSL* ENGINE API includes an engine specifically for Intel® Data Protection Technology with Secure Key. When this engine is enabled, the RAND_bytes() function will exclusively use the RDRAND instruction for generating random numbers and will not need to rely on the OS's entropy pool for re...

Getting Kernel-Based Virtual Machine (KVM) to Work with Intel® Xeon Phi™ Coprocessors
Par loc-nguyen (Intel)Publié le 05/29/20140
The current Kernel-based Virtual Machine (KVM) software does not recognize the existence of Intel® Xeon Phi™ coprocessors. In order to make the KVM recognize the coprocessors, we provide patches under the GPL license, to rebuild the kernel and qemu-kvm packages. The patches provided here are used...

Intel VT-D and Intel X99 motherboards
Par Ward H.0
Hi, I am thinking of buying a X99 motherboard that I can use for Vmware Workstation. The two brands that I am thinking of are ASUS and GigaByte. I have been looking into the Virtualization and plan on running VMWare Workstation 11.  So virtualize windows Server 2012, Windows 8.1 etc. Plus VMWare ESXi. So I think for the last one I need Vt-d. Now I have notice the the ASUS MB's have a few more options for VTD like: Vtd Azalea VCp optimizations. Interrupt Remapping Coherency Support (Non-ISoch) Coherency Support (ISoch) However the GigaByte board only allows me to turn VT-d on and off. So since I can't control these options would they be on by default on the GigaByte, is there anything 'Disadvantage' I have not being able to control them? (Or is all this a bit of a non-issue ?) BTW - I can understand people here might not know specifically about VMWare or the motherboards in question. For example I am wondering if say a board supports VT-d means that these options are inclu...
EPT performance issue
Par Mark S.1
Hi, I developed a hypervisor wich runs smoothly inside VMware Workstation 10 (thanks to virtualization of Intel VT-x/EPT). I'm trying to run this same hypervisor on bare metal (Intel Core i7), but performances are terrible. The guest is set up to execute the following code: mov eax,0x0 start: cmp eax,0xfffffe ja <end> inc eax jmp <start> end: mov rdi,0x1 vmcallwhich executes almost immediatly inside VMware, and takes about 8 seconds (!) on bare metal. I thinks it's related to EPT: when disabled, there is no performance issues anymore (it's quite easy to disable EPT since this code doesn't write to memory: SECONDARY_EXEC_ENABLE_EPT is unset and GUEST_CR3 has the same value than VMM). Do you have suggestions? Thanks a lot.
RSM and multiple cores
Par MP1
Hi all, I am trying to understand a technology that makes use of SMM in relation to hypervisors (hypercheck), and I have a number of questions about SMM in general - I hope I am posting in the right forum. I'd be interested to understand the following: 1) I know that on SMI asserting, all cores (at different interruptible boundaries) will enter SMM: are there spurious cases where SMM is triggered on only less cores? 2) The RSM instruction is said to return the processor to the not-SMM state. Does it need to be executed on every processor in SMM mode? 3) If I am in SMM mode with all my cores (i.e. I wait until them all are in SMM with a mutex), if I execute RSM from one core, does it resume normal operations (i.e. the kernel code it was executing) while the others are left in SMM mode? I am asking because the Default Treatment of RSM (33.14.2) is not exactly clear to me in Intel's doc.   Thanks in advance.

Assign pages to VT-D devices
Par steven7653
Need some help understanding the theory of operation for implementing Vt-D.  I've been through the manual a couple of times.  The part I'm having trouble understanding is when we assign the page tables to the root complex structures.  How does the guest know which frames it's allowed to assign for DMA use?  The only work around I could think of is to either A do a VMCALL and ask, or B mirror the entire range the guest is allowed to access vie EPT and assign that to the root complex structure as well.

How to handle GUID_ZPixelFormats in graphics card driver with Direct3D DirectDraw and DXVA under XDDM
Par Letian Yi2
Hi all: I'm developing a virtual graphics card driver under XDDM. I have finished the DirectDraw part of the driver, and i can see the DirectDraw is enabled in dxdiag. Now i'm developing the D3D part, but when i handle GUID_ZPixelFormats in DdGetDriverInfo,  DirectDraw is disabled ! Does anyone know how to handle GUID_ZPixelFormats in DdGetDriverInfo ? My code: void DdInitZPixelFormats(PDD_GETDRIVERINFODATA lpGetDriverInfo) {     static const DDPIXELFORMAT g_zfmts[] =     {         {             sizeof(DDPIXELFORMAT), DDPF_ZBUFFER, 0,             { 16 }, { 0 }, { 0x0000ffff }, { 0x00000000 }, { 0x00000000 }         },         {             sizeof(DDPIXELFORMAT), DDPF_ZBUFFER, 0,             { 32 }, { 0 }, { 0x00ffffff }, { 0x00000000 }, { 0x00000000 }         },     };     DWORD num = sizeof(g_zfmts) / sizeof(DDPIXELFORMAT);     DWORD size = sizeof(g_zfmts);     UINT8 *buf = (UINT8 *)lpGetDriverInfo->lpvData;     memcpy(buf, g_zfmts, min(lpGetDriverInfo->dwExpe...
