Subject: [Patch v2 0/5] perf: fix test error and improve c2c memory-region display
Date: Mon, 9 Nov 2026 08:43:57 +0800 [thread overview]
Message-ID: <20261109004402.1403713-1-dapeng1.mi@linux.intel.com> (raw)
This patch series fixes a failing object-code reading test and improves
the c2c memory-region display in perf tools. In particular, it adds
memory-region information to the per-cacheline view and ensures that all
sampled memory regions are displayed, rather than only the last one.
These changes improve correctness and make the c2c output more
informative for debugging and analysis.
History:
v1: https://lore.kernel.org/all/20261106073018.903126-1-dapeng1.mi@linux.intel.com/
Dapeng Mi (5):
perf tests: Skip zero sample IP in object-code reading test
perf c2c: Fix top-level histogram ownership check
perf c2c: Show memory region in the per-cacheline view
perf c2c: Show all memory regions in the region column
perf c2c: Rename "Region" column to "Range" for consistency
