It uses GenuineIntel.bin or AuthenticAMD.bin file + placed at the beginning of an initramfs image + (/boot/initramfs-KERNEL_VERSION.img, where "KERNEL_VERSION" is a kernel + version in the same format as provided by "uname -r") as a source + of microcode data, and is performed very early during the boot process + (if the relevant microcode file is available in the aforementioned file). + * On-demand (late) microcode update. It can be triggered by writing "1" to + /sys/devices/system/cpu/microcode/reload file (provided my the "microcode" + module). It relies on request_firmware infrastructure, which searches (and + loads, if found) microcode from a file present in one of the following + directories (in the search order): + /lib/firmware/updates/KERNEL_VERSION/ + /lib/firmware/updates/ + /lib/firmware/KERNEL_VERSION/ + /lib/firmware/ + (there is also an additional directory that can be configured via the + "fw_path_para" module option of the "firmware_class" module; as this module + is built-in in RHEL kernel, a boot parameter "firmware_class.fw_path_para" + should be used for that purpose; this is out of the document's scope, however) + +The firmware for Intel CPUs is searched in "intel-ucode" subdirectory, and for +AMD CPUs, a file under "amd-ucode" is searched. + +For Intel CPUs, the name of the specific microcode file the kernel tries to load +has the format "FF-MM-SS", where "FF" is the family number, "MM" is the model +number, and "SS" is the stepping. All those numbers are zero-filled to two digits +and are written in hexadecimal (letters are in the lower case). For AMD CPUs, +the file name has the format "microcode_amd_famFFh.bin", where "FF" is the +family number, written in hexadecimal, letters are in the lower case, not +zero-filled. + +The early microcode is placed into initramfs image by the "dracut" script, which +scans the aforementioned subdirectories of the configured list of firmware +directories (by default, the list consists of two directories in RHEL 9, +"/lib/firmware/updates" and "/lib/firmware"). + +In RHEL 9, AMD CPU microcode is shipped as a part of the linux-firmware package, +and Intel microcode is shipped as a part of the microcode_ctl package. + +The microcode_ctl package currently includes the following: + * Intel CPU microcode files, placed in /usr/share/microcode_ctl/intel-ucode + directory (currently there are none); + * A dracut module, /usr/lib/dracut/modules.d/99microcode_ctl-fw_dir_override, + that controls which additional firmware directories will be added to dracut's + default configuration; + * A dracut configuration file, /usr/lib/dracut/dracut.conf.d/01-microcode.conf, + that enables inclusion of early microcode to the generated initramfs + in dracut; + * A dracut configuration file, + /usr/lib/dracut/dracut.conf.d/99-microcode-override.conf, that provides a way + to quickly disable 99microcode_ctl-fw_dir-override dracut module; + * A systemd service file, microcode.service, that triggers microcode reload + late during boot; + * A set of directories in /usr/share/microcode_ctl/ucode_with_caveats, each + of which contains configuration and related data for various caveats related + to microcode: + * readme - description of caveat and related information, + * config - caveat configuration file, with syntax as described in "Caveat + configuration" section below, + * intel-ucode - directory containing microcode files related to the caveat; + * A set of support scripts, placed in /usr/libexec/microcode_ctl: + * "check_caveats" is an utility script that performs checks of the target + kernel (and running CPU) in accordance with caveat configuration files + in ucode_with_caveats directory and reports whether it passes them or not, + * "reload_microcode" is a script that is called by microcode.service and + triggers microcode reloading (by writing "1" to + /sys/devices/system/cpu/microcode/reload) if the running kernel passes + check_caveats checks, + * "update_ucode" is a script that populates symlinks to microcode files + in /lib/firmware, so it can be picked up by relevant kernels for the late + microcode loading. + +Also, microcode_ctl RPM includes triggers that run update_ucode script on every +installation or removal of a kernel RPM in order to provide microcode files +for newly installed kernels and cleanup symlinks for the uninstalled ones. + + +Microcode file structure +------------------------ +Intel x86 CPU microcode file (that is, one that can be directly consumed +by the CPU/kernel, and not its text representation such as used in microcode.dat +files) is a bundle of concatenated microcode blobs. Each blob has a header, +payload, and an optional additional data, as follows (for additional information +please refer to "Intel® 64 and IA-32 Architectures Software Developer’s Manual" +[1], Volume 3A, Section 9.11.1 "Microcode Update"): + * Header (48 bytes) + * Header version (unsigned 32-bit integer): version number of the update + header.

Please also refer to README.intel-ucode, section "About + Processor Signature, Family, Model, Stepping and Platform ID" + for additional information. + * Checksum (unsigned 32-bit integer): correct if sum (in base 1 << 32) of all + the 32-bit integers comprising the microcode amounts to 0. + * Loader version (unsigned 32-bit integer): 0x1. + * Platform ID mask (unsigned 32-bit integer): lower 8 bits indicate the set + of possible values of bits 52..50 of MSR 0x17 ("Platform ID").

Currently, the following options are supported: + * "model" option, which has format "VENDOR_ID FF-MM-SS", that specifies + to which CPU model the caveat is applicable (check_caveats ignores caveats + with non-matching models if "-m" option is passed to it). Can be set + in the configuration file only once (the last provided value is used). + * "vendor" option specifies CPUs of which vendor (as provided + in the /proc/cpuinfo file) the caveat is applicable to (check_caveats + ignores caveats with non-matching models when it is invoked with "-m" + option). Can be set in the configuration file only once. + * "path" is a glob pattern that specifies set of microcode files associated + with the caveat as a relative path to the caveat directory. This option + is used for populating files in /lib/firmware by update_ucode script and + for matching microcode file when dracut is run in host-only mode + (as in that case it uses only the first directory in firmware directory list + to look for the microcode file applicable to the host CPU). Can be set + in the configuration file multiple times. + * "kernel" is a minimal kernel version that supports proper handling + of the related microcode files during late microcode load. It may be + provided in one of the following formats that affect the way it is compared + to the running kernel version: + * A.B.C (where A, B, and C are decimal numbers), "upstream version". In this + case, simple version comparison against the respective part of the running + kernel version is used, and the running kernel version should be greater + or equal than the version provided in the configuration option in order + for comparison to succeed (that is, the first part, major version number, + of the running kernel version should be greater than the value provided + in the configuration option, or those should be equal and the second part, + minor version number, should be greater than the minor version number + of the kernel version provided in the configuration option, or the first + two parts should be equal and the third part, patch level, should + be greater or equal the patch level of the version in the configuration + option). + * A.B.C-Y (where A, B, C, and Y are decimal numbers), "Y-stream version". + In this case, A.B.C part should be equal, and Y part of the running kernel + version should be greater or equal than the Y part of the configuration + option version in order to satisfy the comparison requirement. + * A.B.C-Y.Z1.Z2 (where A, B, C, Y, Z1, and Z2 are decimal numbers), + "Z-stream version". In this case, A.B.C-Y part should be equal and Z1.Z2 + part of the running kernel should be greater or equal than the respective + part of the configuration option version (when compared as a version) + for comparison to succeed. + Kernel version check passed if at least one comparison of the running kernel + version against a kernel version provided in a configuration option + succeeded. The "kernel" configuration option can be provided + in the configuration file multiple times. + * "kernel_early" is a minimal kernel version that supports proper handling + of the related microcode during early microcode load. The format of the + option and its semantics is similar to the "kernel" configuration options. + This option can be provided multiple times as well. + * "mc_min_ver_late" is the minimal version of the currently loaded microcode + on the CPU (as reported in /proc/cpuinfo) that supports late microcode + update. Microcode update will be attempted only if the currently loaded + microcode version is greater or equal the microcode version provided + in the configuration option. Can be set in the configuration file only once. + * "disable" is a way to disable a specific caveat from inside its + configuration. Argument for the argument is a list of stages ("early", + "late") for which the caveat should be disable. The configuration option + can be provided multiple times in a configuration file. + * "pci_config_val" performs check for specific values in selected parts + of configuration space of specified PCI devices. If "-m" option + is not specified, then the actual check is skipped, and the check returns + result in accordance with the provided "mode" option (se below). Check + arguments are a white-space-separated list of "key=value" pairs. + The following keys are supported: + * "domain" - PCI domain number, or "*" (an asterisk) for any domain. + Default is "*". + * "bus" - PCI bus number, or "*" (an asterisk) for any bus. Default is "*". + * "device" - PCI device number, or "*" (an asterisk) for any device. + Default is "*". + * "function" - PCI function number, or "*" (an asterisk) for any function. + Default is "*". + * "vid" - PCI vendor ID, or empty string for any vendor ID. Default + is empty string. + * "did" - PCI device ID, or empty string for any device ID. Default + is empty string. + * "offset" - offset in device's configuration space where the value resides. + Default is 0. + * "size" - field size. Possible values are 1, 2, 4, or 8. Default is 4. + * "mask" - mask applied to the values during the check. Default is 0. + * "val" - comma-separated list of matching values. Default is 0. + * "mode" - check mode, the way matches are interpreted: + * "success-any" - check succeeds if there was at least one match, + otherwise it fails. + * "success-all" - check succeeds if there was at least one device checked + and all the checked devices have matches, otherwise the check fails. + * "fail-any" - check fails if there was at least one match, otherwise + it succeeds. + * "fail-all" - check fails if there was at least one device checked + and all the checked devices have matches, otherwise the check succeeds. + Default is "success-any". + An example of a check: + pci_config_val mode=success-all device=30 function=3 vid=0x8086 did=0x2083 offset=0x84 size=4 mask=0x38 val=0x38,0x18,0x8 + It interprets 4 bytes at offset 0x84 of special files "config" under + directories that match glob pattern "/sys/bus/pci/devices/*:*:1e.3" + as an unsigned integer value, applies mask 0x38 (thus selecting bit 5..3 + of it) and checks whether it is one of the values 0x38, 0x18, or 0x8 (0b111, + 0b011, or 0b001 in bits 5..3, respectively); if there are such files, + and all the checked values in every checked file has matched at least one + of the aforementioned value, then the check is successful, otherwise + it fails (in accordance with "mode=success-all" semantics). This check fails + if "-m" option is not specified. + * "dmi" performs checks for specific values available in DMI sysfs files + (present under /sys/devices/virtual/dmi/id/). The check (when it is actually + performed; see a not about "no-model-mode" below) fails if one of the files + is not readable. If "-m" option is not specified, then the actual check + is skipped, and the check returns value in accordance with "no-model-mode" + parameter value (see below). Check arguments are a white-space-separated + list of "key=value" pairs. The following keys are supported: + * "key" - DMI file to check. Value can be one of the following: bios_date, + bios_vendor, bios_version, board_asset_tag, board_name, board_serial, + board_vendor, board_version, chassis_asset_tag, chassis_serial, + chassis_type, chassis_vendor, chassis_version, product_family, + product_name, product_serial, product_uuid, product_version, sys_vendor. + Default is empty string. + * "val" - a string to match DMI data present in "key" against. + Can be enclosed in single or double quotes. Default is empty string. + * "keyval" - a pair of "key" and "val" values (with semantics described + above), separated with either "=", ":", "!=", or "!:" characters. Enables + providing of multiple key-value pairs by means of supplying multiple + keyval= parameters. The exclamation sign ("!") character in separator + enables negated matching (so, non-equality of the value in DMI "key" file + and the value of "val" is). The match considered successful when all + the key/val (non-)equalities are in effect. This parameter works + in addition to the pair provided in "key" and "val" parameters + (but allows to avoid using them). Default is empty. + * "mode" - check mode, the way successful matches are interpreted: + * "success-equal" - returns 0 if the value present in the file + with the name supplied via the "key" parameter file under + /sys/devices/virtual/dmi/id/ is equal to the value supplied as a value + of "val" parameter and all the pairs provided in "keyval" parameters + are equal and non-equal in accordance with their definition, + otherwise 1. + * "fail-equal" - returns 1 if the value present in the file + with the name supplied via the "key" parameter file under + /sys/devices/virtual/dmi/id/ is equal to the value supplied as a value + of "val" parameter and all the pairs provided in "keyval" parameters + are equal and non-equal in accordance with their definition, + otherwise 0. + Default is "success-any". + * "no-model-mode" - return value if model filter ("-m" option) + is not enabled: + * "success" - return 0. + * "fail" - return 1. + Default is "success". + An example of a check: + dmi mode=fail-equal no-model-mode=success key=bios_vendor val="Dell Inc." + It checks file /sys/devices/virtual/dmi/id/bios_vendor and fails if its + content is "Dell Inc." (without quotes). It succeeds if "-m" option + is not enabled. + Another example: + dmi mode=fail-equal keyval="sys_vendor=Amazon EC2" keyval="product_name=u-18tb1.metal" + dmi mode=fail-equal keyval="sys_vendor=Lenovo" keyval="product_name=ThinkSystem SR950" + It blocks the caveat from using when either both + /sys/devices/virtual/dmi/id/sys_vendor contains the string "Amazon EC2" + and /sys/devices/virtual/dmi/id/product_name contains the string + "u-18tb1.metal" or both /sys/devices/virtual/dmi/id/sys_vendor contains + the string "Lenovo" and /sys/devices/virtual/dmi/id/product_name contains + the string "ThinkSystem SR950", but enables caveat loading for other products + with the aforementioned /sys/devices/virtual/dmi/id/sys_vendor values, + for example. + * "dependency" allows conditional enablement of a caveat based on the check + status of some other caveat(s). It has the following format: + dependency DEPENDENCY_TYPE DEPENDENCY_NAME [OPTION...] + where DEPENDENCY_NAME is the configuration to be checked, OPTIONs + are per-DEPENDENCY_TYPE, and the only DEPENDENCY_TYPE that is supported + currently is "required". + Options for the "required" dependency type: + * "match-model-mode" - whether model matching mode ("-m" option) + has to be used for the nested configuration check. Possible values: + * "on" - model-matching mode is always used during the nested check; + * "off" - model-matching mode is never used during the nested check; + * "same" - used the same model-matching mode as it is now. + Default is "same". + * "skip" - controls result of the check when the nested check indicated + skipping of the configuration. + * "fail" - the dependent check fails; + * "success" - the dependent check succeeds; + * "skip" - the dependent check indicates that the configuration + is to be skipped. + Default is "skip". + * "force-skip" - controls result of the check when the nested check + indicated skipping of the configuration caused by the presence + of an override file (see "check_caveats script" section for details). + * "fail" - the dependent check fails; + * "success" - the dependent check succeeds; + * "skip" - the dependent check indicates that the configuration + is to be skipped. + Default is "skip". + * "nesting-too-deep" - as a measure against dependency loop, configuration + checking logic implements nesting limit on dependency checks (currently + set at 8). This option controls the behaviour of the check + when the nested check cannot be performed due to this limit. + * "fail" - the dependent check fails; + * "success" - the dependent check succeeds; + * "skip" - the dependent check indicates that the configuration + is to be skipped. + Default is "fail". + An example of a check: + dependency required intel skip=success match-model-mode=off + It checks "intel" caveat configuration (see the "Early microcode load + inside a virtual machine" section) with model-matching mode being disabled, + treats skipping of the configuration as a success (unless the configuration + is forced to be skipped, in that case the dependent configuration + is to be skipped as well). + + +check_caveats script +-------------------- +"check_caveats" is an utility script (called by update_ucode, reload_microcode, +dracut module) that performs checks of the target kernel (and running CPU) +in accordance with caveat configuration files in directory +"/usr/share/microcode_ctl/ucode_with_caveats", and returns information, whether +the system passes the checks, or not. + +Usage: + check_caveats [-e] [-k TARGET_KVER] [-c CONFIG]* [-m] [-v]' + +Options: + -e - check for early microcode load possibility (instead of late microcode + load). "kernel_early" caveat configuration options are used for checking + instead of "kernel", and "mc_min_ver_late" is not checked. + -k - target kernel version to check against, $(uname -r) is used otherwise. + -c - caveat(s) to check, all caveat configurations found inside + $MC_CAVEATS_DATA_DIR are checked otherwise. + -m - ignore caveats that do not apply to the current CPU model. + -v - verbose output. + +Environment: + MC_CAVEATS_DATA_DIR - directory that contains caveats configurations, + "/usr/share/microcode_ctl/ucode_with_caveats" + by default. + FW_DIR - directory containing firmware files (per-kernel configuration + overrides are checked there), "/lib/firmware" by default. + CFG_DIR - directory containing global caveats overrides, + "/etc/microcode_ctl/ucode_with_caveats" by default. + +Output: + Script returns information about caveats check results. Output has a format + of "KEY VALUE1 VALUE2 ..." with KEY defining the semantics of the VALUEs. + Currently, the following data is issued: + - "cfgs" - list of caveats that have been processed (and not skipped + due to missing "config", "readme", or a disallow-* override described + below); + - "skip_cfgs" - list of caveats that have been skipped (due to missing + config/readme file, or because of overrides); + - "paths" - list of glob patterns matching files associated with caveats + that have been processed; + - "ok_cfgs" - list of caveat configurations that have all the checks passed + (or have enforced by one of force-* overrides described below); + - "ok_paths" - list of glob patterns associated with caveat files from + the "ok_cfgs" list; + - "fail_cfgs" - list of caveats that have one of the checks failed. + - "fail_paths" - list of glob patterns associated with caveats from the + "fail_cfgs" list. + +Return value: + - 0 in case caveats check has passed, 1 otherwise. + - In "-d" mode, 0 is always returned. + +Overrides: + +When check_caveats perform its checks, it also checks for presence of files +in specific places, and, if they exist, check_caveats skips a caveat or ignores +its checks; that mechanism allows overriding the information provided +in configuration on local systems and affect the behaviour of the microcode +update process. + +Current list of overrides (where $FW_DIR and $CFG_DIR are the environment +options described earlier; $kver - the currently processed kernel version, +$s is the requested stage ("early" or "late"), $cfg is the caveat directory +name): + $FW_DIR/$kver/disallow-$s-$cfg - skip a caveat for the requested stage for + a specific kernel version.. + $FW_DIR/$kver/force-$s-$cfg - apply a specific caveat file for a specific + kernel version for the requested stage without + performing any checks. + $FW_DIR/$kver/disallow-$cfg - skip a caveat for any stage for a specific + kernel version. + $FW_DIR/$kver/force-$cfg - apply a specific caveat for any stage + for a specific kernel version without checks. + $FW_DIR/$kver/disallow-$s - skip all caveats for a specific stage + for a specific kernel version. + $CFG_DIR/disallow-$s-$cfg - skip a caveat for a specific stage for all + kernel versions. + $FW_DIR/$kver/force-$s - apply all caveats for a specific stage + for a specific kernel version without checks. + $CFG_DIR/force-$s-$cfg - apply a specific caveat for a specific stage for + all kernel versions without checks. + $FW_DIR/$kver/disallow - skip all caveats for all stages for a specific + kernel version. + $CFG_DIR/disallow-$cfg - skip a caveat for all stages for all kernel + versions. + $FW_DIR/$kver/force - apply all caveats for all stages for a specific kernel + version without checks. + $CFG_DIR/force-$cfg - apply a caveat for all stages for all kernel versions + without checks. + $CFG_DIR/disallow-$s - skip all caveat for all kernel versions + for a specific stage. + $CFG_DIR/force-$s - apply all caveats for all kernel versions for specific + stage without checks. + $CFG_DIR/disallow - skip all caveats for all stages for all kernel versions + (disable everything). + $CFG_DIR/force - force all caveats for all stages for all kernel versions + (enable everything). + +The "apply" action above means creating symlinks in /lib/firmware by +update_ucode in case of the "late" stage and adding caveat directory to the list +of firmware directories by dracut plugin in case of the "early" stage. + +The files are checked for existence until the first match, so more specific +overrides can override more broad ones. + +Also, a caveat is ignored if it lacks either config or readme file. + + +update_ucode script +------------------- +"update_ucode" populates symlinks to microcode files in accordance with caveats +configuration. It enables late microcode loading that is invoked by triggering +/sys/devices/system/cpu/microcode/reload file. Since caveats depend +on the kernel version, symlinks are populated inside +"/lib/firmware/KERNEL_VERSION" directory for each installed kernel. +As a consequence, this script is triggered upon each kernel package installation +and removal. + +The script has two parts: common and kernel-version-specific. + +During the common part, files are populated from +/usr/share/microcode_ctl/intel-ucode in /lib/firmware/intel-ucode. There are +several possibilities to affect the process: + * Presence of "/etc/microcode_ctl/intel-ucode-disallow" file leads to skipping + the common part of the script. + * The same for "/lib/firmware/intel-ucode-disallow". + +During the kernel-version-specific part, each caveat is checked against every +kernel version, and those combinations, for which caveat check succeeds, +gets the symlinks to the associated microcode files populated. + * Absence of "/lib/firmware/KERNEL_VERSION/readme-CAVEAT" prevents update_ucode + from removing symlinks related to the caveat for specific kernel version. + * Since the check is being done by check_caveats, all the overrides that + described there also stay. + +Usage: + update_ucode [--action {add|remove|refresh|list}] [--kernel KERNELVER]* + [--verbose] [--dry-run] [--cleanup intel_ucode caveats_ucode] + [--skip-common] [--skip-kernel-specific] + +Options: + --action - action to perform. Currently, the following actions are supported: + * "add" - create new symlinks. + * "remove" - remove old symlinks that are no longer needed. + * "refresh" - re-populate symlinks. + * "list" - list files under control of update_ucode. + By default, "refresh" action is executed. + --kernel - kernel version to process. By default, list of kernel versions + is formed based on contents of /lib/firmware and /lib/modules + directories. + --verbose - verbose output. + --dry-run - do not call commands, just print the invocation lines. + --cleanup - cleanup mode. Used by post-uninstall script during package + upgrades.

This check can be overridden and skipped +by creation of a file "/etc/microcode_ctl/ignore-hypervisor-flag". + +The script has no options and always returns 0. + + +99microcode_ctl-fw_dir_override dracut module +--------------------------------------------- +This dracut module injects directories with microcode files for caveats +that pass "early" check_caveats check (with "-e" flag).
