From 441d07d2b1be0bf7b9f6fbd917fdd89aeb4fb253 Mon Sep 17 00:00:00 2001 From: Tibor Frank Date: Tue, 2 Aug 2022 10:53:28 +0200 Subject: Trending: Prepare static content for the new UTI - Chapter "jenkins jobs": deleted, the neccesary information is in "Performance Tests". - Chapter "perpatch_performance_tests": deleted, should be somewhere else. - Chapter "testbed_hw_configuration": no information was there for years. - Chapter "performance_tests": deleted. - Other chapters: Edited, updated, simplyfied.
