Each 17 telem<x> directory has an associated telem file. This file 18 may be opened and mapped or read to access the telemetry space 19 of the device. The register layout of the telemetry space is 20 determined from an XML file that matches the PCI device id and 21 GUID for the device. 22 23 What: /sys/class/intel_pmt/telem<x>/telem 24 Date: October 2020 25 KernelVersion: 5.10 26 Contact: David Box <david.e.box@linux.intel.com> 27 Description: 28 (RO) The telemetry data for this telemetry device. This file 29 may be mapped or read to obtain the data. 30 31 What: /sys/class/intel_pmt/telem<x>/guid 32 Date: October 2020 33 KernelVersion: 5.10 34 Contact: David Box <david.e.box@linux.intel.com> 35 Description: 36 (RO) The GUID for this telemetry device. The GUID identifies 37 the version of the XML file for the parent device that is to 38 be used to get the register layout. 39 40 What: /sys/class/intel_pmt/telem<x>/size 41 Date: October 2020 42 KernelVersion: 5.10 43 Contact: David Box <david.e.box@linux.intel.com> 44 Description: 45 (RO) The size of telemetry region in bytes that corresponds to 46 the mapping size for the telem file. 47 48 What: /sys/class/intel_pmt/telem<x>/offset 49 Date: October 2020 50 KernelVersion: 5.10 51 Contact: David Box <david.e.box@linux.intel.com> 52 Description: 53 (RO) The offset of telemetry region in bytes that corresponds to 54 the mapping for the telem file. 55 56 What: /sys/class/intel_pmt/crashlog<x> 57 Date: October 2020 58 KernelVersion: 5.10 59 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 60 Description: 61 The crashlog<x> directory contains files for configuring an 62 instance of a PMT crashlog device that can perform crash data 63 recording. Each crashlog<x> device has an associated crashlog 64 file. This file can be opened and mapped or read to access the 65 resulting crashlog buffer. The register layout for the buffer 66 can be determined from an XML file of specified GUID for the 67 parent device. 68 69 What: /sys/class/intel_pmt/crashlog<x>/crashlog 70 Date: October 2020 71 KernelVersion: 5.10 72 Contact: David Box <david.e.box@linux.intel.com> 73 Description: 74 (RO) The crashlog buffer for this crashlog device. This file 75 may be mapped or read to obtain the data. 76 77 What: /sys/class/intel_pmt/crashlog<x>/guid 78 Date: October 2020 79 KernelVersion: 5.10 80 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 81 Description: 82 (RO) The GUID for this crashlog device. The GUID identifies the 83 version of the XML file for the parent device that should be 84 used to determine the register layout. 85 86 What: /sys/class/intel_pmt/crashlog<x>/size 87 Date: October 2020 88 KernelVersion: 5.10 89 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 90 Description: 91 (RO) The length of the result buffer in bytes that corresponds 92 to the size for the crashlog buffer. 93 94 What: /sys/class/intel_pmt/crashlog<x>/offset 95 Date: October 2020 96 KernelVersion: 5.10 97 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 98 Description: 99 (RO) The offset of the buffer in bytes that corresponds 100 to the mapping for the crashlog device. 101 102 What: /sys/class/intel_pmt/crashlog<x>/enable 103 Date: October 2020 104 KernelVersion: 5.10 105 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 106 Description: 107 (RW) Boolean value controlling if the crashlog functionality 108 is enabled for the crashlog device. 109 110 What: /sys/class/intel_pmt/crashlog<x>/trigger 111 Date: October 2020 112 KernelVersion: 5.10 113 Contact: Alexander Duyck <alexander.h.duyck@linux.intel.com> 114 Description: 115 (RW) Boolean value controlling the triggering of the crashlog 116 device node. When read it provides data on if the crashlog has 117 been triggered. When written to it can be used to either clear 118 the current trigger by writing false, or to trigger a new 119 event if the trigger is not currently set.
