model GenuineIntel 06-55-04 path intel-ucode/06-55-04 ## Bug https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/21 ## affects only SKX-W/X (Workstation and HEDT segments); product segment ## can be determined by checking bits 5..3 of the CAPID0 field in PCU registers ## device (see https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-scalable-spec-update.pdf#page=13 ## for Server/FPGA/Fabric segments description; for SKX-W/X no public ## documentation seems to be available). Specific device/function numbers ## are provided for speeding up the search only, VID:DID is the real selector. ## Commented out since revision 0x2006906 seems to fix the issue. #pci_config_val mode=success-all device=0x1e function=3 vid=0x8086 did=0x2083 offset=0x84 size=4 mask=0x38 val=0x38,0x18,0x8 ## The "kernel_early" statements are carried over from the intel caveat config ## in order to avoid enabling this newer microcode on these problematic kernels; ## see the caveat description in /usr/share/doc/microcode_ctl/caveats/intel_readme ## (That also means that this caveat has to be enforced separately on these ## kernels.) kernel_early 4.10.0 kernel_early 3.10.0-930 kernel_early 3.10.0-862.14.1 kernel_early 3.10.0-693.38.1 kernel_early 3.10.0-514.57.1 kernel_early 3.10.0-327.73.1
