CentOS 6.9 has support for the Haswell processor which is a subset of the Skylake. All Skylake server ancillary components work perfectly with CentOS 6.9. The AST2500 used with the Skylake is very good and will process UHD. However this is not backwards compatible with legacy variants. To make it work an ancillary graphics card is required which is less than $100. This will...

Hello, I have a pre-production Intel Skylake server using dual 8176 processors (28 core @2.1Ghz) I have loaded from the DVD distribution CentOS 7.3 and RHEL 7.4 with no problems. When I try and load CentOS 6.9 the boot process hangs just as the Anaconda graphics is started for CentOS configuration. If I use a secondary graphics card then t...

...surprising. But what surprises me is that those models are still reported from virConnectCompareCPU as supported (VIR_CPU_COMPARE_SUPERSET) in the nested environment and VMs can be started happily with them. For instance, virConnectGetDomainCapabilities reports <model usable='no'>Skylake-Client</model> but when I try to use that model anyway, the VM starts fine with it: <cpu mode='custom' match='exact' check='full'> <model fallback='forbid'>Skylake-Client</model> <topology sockets='16' cores='1'...

Hello, 1. Can you please tell me how can I find the type of my Intel Xeon?I see in LLVM code that Intel Xeon processors can be of type "core2", "penryn", "westmere", "skylake". 2. I also see that "skylake" can be a type and a subtype as well.How can I find out the subtype of my architecture? Looking forward for you answer.

Hi -- I have found a bug in an HPC code where llvm is vectorizing a loop on Skylake that has an obvious recurrence. I derived a small test case based on the original benchmark below: /*****************************************************************/ static void __attribute__ ((always_inline)) one( const int *restrict in, const int *const end, const unsigned shift, int *cons...

Hello, I have an Intel NUC6i5 (Skylake i5-6260u processor) running CentOS 6.9 and there are no real problems. However during boot an error occurs in dmesg where a PCH unknown device 0x9d48 is logged. How can I get rid of this error output? Thank you, Mark

Hi, I have a JIT compiler using the legacy JIT on LLVM 3.5 that, when run on the Xeon v5 Skylakes produces "Cannot select: intrinsic %llvm.x86.sse41.round.sd". Note, this does not occur on i7 Kabylakes. To get this far I had to disable AVX512 code gen. Upgrading the system I am looking at from 3.5 to a later version is a big job that I'd prefer not to have on my critical path....

I don't see support detecting skylake or even avx-512 support in the autodetection code that far back. Are you doing the same thing for the i7 kabylake?

Hello, Could someone please answer the following question: Does LLVM support code generation for Intel Processors? Which Intel processors are supported? I am interested especially in Intel Xeon Processor, but you can give me information about the others as well. Thank you,Iulia -------------- next part -------------- An HTML attachment was scrubbed... URL:

...think. The CPU autodetection code lives in getHostCPUName in lib/Support/Host.cpp, but I don't think the JIT calls into. I think its expected the user would call it or pass a specific CPU string to the MCPU for the EngineBuilder. But getHostCPUName in LLVM 3.5 doesn't recognize Kabylake or Skylake. The Cannot select: means that an intrinsic was used but no pattern could be found in lib/Target/X86/X86GenDAGISel.inc that applies to the enabled feature set. We have separate patterns for that intrinsic for at least SSE4.1 and AVX1 in 3.5. So that implies that the EngineBuilder thinks your CPU d...

If reboot boot the 7.3 kernel 3.10.0-514.26.2.el7.x86_64 kernel everything works just fine, so my guess is that there's a kernel issue with the hardware, specifically the Skylake processor.
