Additional note for (2): "The issue was that pahole ran out of memory (peak memory usage of pahole was around 2.5GB)." "Current linux build needs at least 10GB of RAM!"to build kernel 6.5" |

Regarding (1), "Error: No libopencsd library found or the version is not up-to-date. Please install recent libopencsd to build with CORESIGHT=1. " ============================ commit 2dbba30fd69b604802a9535b74bddb5bcca23793 Author: James Clark <james.clark@arm.com> Date: Fri Sep 1 14:37:15 2023 +0100 perf cs-etm: Bump minimum OpenCSD version to ensure a bugfix is present +#error "OpenCSD >= 1.2.1 is required" ============================ Note that the system has version 1.2.0: opencsd-1.2.0-2.el9.aarch64 Therefore the problem seems to be 'No libopencsd library found' rather than the version number. |

linux 6.8-rc2 is out. Same result: build succeeds only when perf is disabled. |

To find out the patch that causes error (1), I did a git bisection. The result is: [toracat@aarch64-02 linux]$ git bisect good 2dbba30fd69b604802a9535b74bddb5bcca23793 is the first bad commit commit 2dbba30fd69b604802a9535b74bddb5bcca23793 Author: James Clark <james.clark@arm.com> Date: Fri Sep 1 14:37:15 2023 +0100 perf cs-etm: Bump minimum OpenCSD version to ensure a bugfix is present Since commit d927ef5004ef ("perf cs-etm: Add exception level consistency check"), the exception that was added to Perf will be triggered unless the following bugfix from OpenCSD is present: - _Version 1.2.1_: - __Bugfix__: ETM4x / ETE - output of context elements to client can in some circumstances be delayed until after subsequent atoms have been processed leading to incorrect memory decode access via the client callbacks. Fixed to flush context elements immediately they are committed. Rather than remove the assert and silently fail, just increase the minimum version requirement to avoid hard to debug issues and regressions.

The bisect result was not surprising. The "culprit" patch checks to see if opencsd is version 1.2.1 or newer. For some reason this check fails on aarch64-02, Therefore omitting the patch leads to a successful build. The system does have opencsd 1.2.1. Knowing that,, it may be OK to skip the patch. But the question remains as to why the patch does not see the version correctly. |
|
|
D'oh ! The commit says "OpenCSD >= 1.2.1 is required". But we have 1.2.0. That explains it. |
|
|
Solution/workaround - Build opencsd-1.3.1 using the src.rpm from Fedora 39 - Provide opencsd-1.3.1 through a local repo in mock As of linux-6.7.4 and linux-6.1.77, the commit that changed the requirement for opencsd >= 1.2.1 was added. Therefore the customized mock is needed for all current and future builds (aarch64). |
