description |
[Impact]
During heavy load, the following message may appear on the console of a HiSilicon D06 system:
arm-smmu-v3 arm-smmu-v3.3.auto: CMD_SYNC timeout
This is due to a bug that can also impact system performance, as the CPU is blocked until the timeout occurs.
[Test Case]
The Ubuntu server certification test suite hits this pretty reliably during the stress-ng tests, although I haven't narrowed it down to exactly which test yet.
[Regression Risk]
Limited to arm64 systems. This change has been upstream since 4.20 w/o any noticed regressions (based on lack of Fixes: commits). Regressions could manifest as a performance hit. |
