Subject: [Bug 215740] kernel warning: DMA-API: xhci_hcd: cacheline tracking EEXIST, overlapping mappings aren't supported
Date: Tue, 03 Jun 2025 19:09:39 +0000 [thread overview]
Message-ID: <bug-215740-208809-vJtwCqkZ9S@https.bugzilla.kernel.org/> (raw)

--- Comment #44 from Alan Stern (stern@rowland.harvard.edu) ---
That seems reasonable.
Some people may object, on the grounds that turning on debugging should not
affect the way the kernel (memory allocation in particular) behaves --
otherwise what you're debugging isn't the same as what normally happens. But
given the way the DMA API debugging is set up, I don't see any alternative.
Can somebody test this patch?
