intel-cmt-cat-25.04-1.el9 RPM for i686

From CentOS Stream 9 BaseOS for x86_64

This software package provides basic support for
Cache Monitoring Technology (CMT), Memory Bandwidth Monitoring (MBM),
Cache Allocation Technology (CAT), Memory Bandwidth Allocation (MBA),
and Code Data Prioratization (CDP).

CMT, MBM and CAT are configured using Model Specific Registers (MSRs)
to measure last level cache occupancy, set up the class of service masks and
manage the association of the cores/logical threads to a class of service.
The software executes in user space, and access to the MSRs is
obtained through a standard Linux* interface. The virtual file system
provides an interface to read and write the MSR registers but
it requires root privileges.

Changelog

* Fri Oct 24 2025 Tony Camuso <tcamuso@redhat.com> - 25.04-1
  - Update to latest upstream.
  - Clean up install paths, drop obsolete patches, and improve flag injection
  handling
  - Replaced hard-coded install paths in Makefiles with sed-based DESTDIR
    fixes for lib, pqos, rdtset, and membw
    - Using sed during %prep is more robust and version-agnostic than patching,
      which requires rebasing each release
  - Relocated admin tools (pqos*, rdtset) from /usr/bin to /usr/sbin for FHS
    compliance
    - These tools require root and interact with system-level cache controls
  - Updated %files to match SONAME bump (libpqos.so.5 -> libpqos.so.6) introduced
    upstream
  - Dropped patches 0001, 0002, 0004, 0005
    - 0001/0002 replaced by sed
  - Ensure CFLAGS and LDFLAGS are augmented, not overridden by using sed to
    convert assignments to +=
    - Ensures compatibility with distro-injected flags (e.g. -O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1  -m32 -march=i686 -mtune=generic -msse2 -mfpmath=sse -mstackrealign -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection,
      hardening) without carrying a version-specific patch
    Resolves: RHEL-122380
* Fri Mar 01 2024 Eugene Syromiatnikov <esyr@redhat.com> - 23.11-2
  - Revert commit "lib: update detection of non-architectural L3CAT" that removed
    L3CAT detection support on Tiger Lake and Erkhart Lake CPUs (RHEL-22729)
* Mon Feb 12 2024 Eugene Syromiatnikov <esyr@redhat.com> - 23.11-1
  - Rebase to 23.11 (RHEL-22729, RHEL-25781)
