This is a note to let you know that I've just added the patch titled perf tools: Correct SNOOPX field offset to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: perf-tools-correct-snoopx-field-offset.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c8281cbe480df2c47b378b20cbee1899eb0861c8 Author: Al Grant <al.grant@xxxxxxxxxxxx> Date: Tue Sep 1 12:10:14 2020 -0300 perf tools: Correct SNOOPX field offset [ Upstream commit 39c0a53b114d0317e5c4e76b631f41d133af5cb0 ] perf_event.h has macros that define the field offsets in the data_src bitmask in perf records. The SNOOPX and REMOTE offsets were both 37. These are distinct fields, and the bitfield layout in perf_mem_data_src confirms that SNOOPX should be at offset 38. Committer notes: This was extracted from a larger patch that also contained kernel changes.
