Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem: For AMD updates, the microcode isn't updated early as it is for Intel systems when updating the microcode_ctl rpm. Can we please add a %posttrans script for linux-firmware to force an update using 'dracut -f' to rebuild the initramfs.img Version-Release number of selected component (if applicable): linux-firmware-20180518-63.git2a9b2cf.el7.noarch.rpm How reproducible: Always Steps to Reproduce: 1. Find an AMD system that requires an update 2. Provision with RHEL7 3. yum update linux-firmware and reboot 4. Note the logs do not indicate an early microcode update Actual results: no indication that microcode was updated early in the logs Expected results: microcode updated early to new patch_level ... is seen in the logs Additional info: From jbastian: "The linux-firmware %posttrans script may want to be a bit more selective i.e., check if the system has an AMD CPU, something like if [ -d /run/systemd/system ]; then if grep -q AuthenticAMD /proc/cpuinfo ; then dracut -f fi fi" ~]# cat /sys/devices/system/cpu/cpu0/microcode/version 0x600084f ~]# yum update linux-firmware-20180518-63.git2a9b2cf.el7.noarch.rpm ... ~]# reboot ... ~]# grep -i microcode /var/log/dmesg [ 3.671328] microcode: CPU0: patch_level=0x0600084f [ 3.676233] microcode: CPU1: patch_level=0x0600084f [ 3.681276] microcode: CPU2: patch_level=0x0600084f [ 3.686207] microcode: CPU3: patch_level=0x0600084f [ 3.691250] microcode: CPU4: patch_level=0x0600084f [ 3.696187] microcode: CPU5: patch_level=0x0600084f [ 3.701050] microcode: CPU6: patch_level=0x0600084f [ 3.705918] microcode: CPU7: patch_level=0x0600084f [ 3.710790] microcode: CPU8: patch_level=0x0600084f [ 3.715656] microcode: CPU9: patch_level=0x0600084f [ 3.720668] microcode: CPU10: patch_level=0x0600084f [ 3.725622] microcode: CPU11: patch_level=0x0600084f [ 3.730752] microcode: CPU12: patch_level=0x0600084f [ 3.735770] microcode: CPU13: patch_level=0x0600084f [ 3.740898] microcode: CPU14: patch_level=0x0600084f [ 3.745918] microcode: CPU15: patch_level=0x0600084f [ 3.751154] microcode: Microcode Update Driver: v2.01 <tigran.co.uk>, Peter Oruba [ 5.386180] [drm] Loading R100 Microcode ~]# cat /sys/devices/system/cpu/cpu0/microcode/version 0x6000852 ~]# dracut -f ~]# reboot ~]# grep -i microcode /var/log/dmesg [ 3.662735] microcode: microcode updated early to new patch_level=0x06000852 [ 3.669792] microcode: CPU0: patch_level=0x06000852 [ 3.674656] microcode: CPU1: patch_level=0x06000852 [ 3.679668] microcode: CPU2: patch_level=0x06000852 [ 3.684533] microcode: CPU3: patch_level=0x06000852 [ 3.689546] microcode: CPU4: patch_level=0x06000852 [ 3.694414] microcode: CPU5: patch_level=0x06000852 [ 3.699428] microcode: CPU6: patch_level=0x06000852 [ 3.704296] microcode: CPU7: patch_level=0x06000852 [ 3.709166] microcode: CPU8: patch_level=0x06000852 [ 3.714033] microcode: CPU9: patch_level=0x06000852 [ 3.719047] microcode: CPU10: patch_level=0x06000852 [ 3.724002] microcode: CPU11: patch_level=0x06000852 [ 3.729102] microcode: CPU12: patch_level=0x06000852 [ 3.734056] microcode: CPU13: patch_level=0x06000852 [ 3.739005] microcode: CPU14: patch_level=0x06000852 [ 3.743958] microcode: CPU15: patch_level=0x06000852 [ 3.749106] microcode: Microcode Update Driver: v2.01 <tigran.co.uk>, Peter Oruba [ 5.649682] [drm] Loading R100 Microcode
