Subject: [PATCH v4 0/4] perf/amd/ibs: Add Zen5 support (tools changes)

IBS on Zen5:
- Introduced Load Latency filtering capability.
- Shows DTLB and page size information differently from prior generations.

Kernel changes for these enhancements are already upstream. So, resending
tools changes separately.

Patches are prepared on perf-tools-next/perf-tools-next (85447f68a1e3).

v3: https://lore.kernel.org/r/20250205060547.1337-1-ravi.bangoria@amd.com
v3->v4:
- Remove kernel changes.
- Improve IBS sample period unit test


Ravi Bangoria (4):
  perf amd ibs: Add Load Latency bits in raw dump
  perf amd ibs: Incorporate Zen5 DTLB and PageSize information
  perf mem/c2c amd: Add ldlat support
  perf test amd ibs: Add sample period unit test
