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:
Build failure with GCC6 because of unused variables,
introduced when disabling Allwinner AHCI and
gd-passthrough-i440FX support.
To work around the build failure, one can pass --disable-werror at
configure time.
Problem introduced with two commits:
a41119d Disable igd-passthrough-i440FX
8a9aadf Disable allwiner_ahci device
Version-Release number of selected component (if applicable):
Introduced in qemu-kvm-rhev-2.6.0-17.el7
How reproducible: 100% with GCC6
Steps to Reproduce:
1. Build with GCC6
Actual results:
<..>/qemu-kvm/hw/pci-host/piix.c:833:23: error: ‘igd_passthrough_i440fx_info’ defined but not used [-Werror=unused-const-variable=]
static const TypeInfo igd_passthrough_i440fx_info = {
cc1: all warnings being treated as errors
and:
