The erratum titled “Disabling of data prefetcher with outstanding prefetch TLB miss might cause a deadlock” should not be handled within TF-A. The current workaround attempts to follow option 2 but misapplies it. Specifically, it statically sets PF_MODE to conservative, which is not the recommended approach. According to the erratum documentation, PF_MODE should be configured in conservative mode only when we disable data prefetcher however this is not done in TF-A and thus the workaround is not needed in TF-A. The static setting of PF_MODE in TF-A does not correctly address the erratum and may introduce unnecessary performance degradation on platforms that adopt it without fully understanding its implications. To prevent incorrect or unintended use, the current implementation of this erratum workaround should be removed from TF-A and not adopted by platforms.
