| Summary: | Provides command line interface to CMT, MBM, CAT, CDP and MBA technologies |
| Description: | 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. |
- 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
- Revert commit "lib: update detection of non-architectural L3CAT" that removed L3CAT detection support on Tiger Lake and Erkhart Lake CPUs (RHEL-22729)
- Rebase to 23.11 (RHEL-22729, RHEL-25781)
