https://bugzilla.kernel.org/show_bug.cgi?id=210777 --- Comment #3 from Harald Jenny (harald@xxxxxxxxxxxxxxxxxxxxx) --- The problem is presumably related to the changes in the DMA mapping in kernel 5.10 (commit 5a32c3413d3340f90c82c84b375ad4b335a59f28) as pwc uses noncoherent DMA buffers. Reverting commit 1161db6776bd1c35257e1e362e91bcb1b3fe4347 (which fixes performance issues) make pwc work again but opens up the orginial problem of transfer rates on armv7l. -- You may reply to this email to add a comment.
