# # and then the receive logic (through ath_rx_tasklet()) will fetch # incoming packets # # static bool ath_edma_get_buffers(..) # .. # dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr, # common->rx_bufsize, DMA_FROM_DEVICE); # # ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data); # if (ret == -EINPROGRESS) { # /let device gain the buffer again/ # dma_sync_single_for_device(sc->dev, bf->bf_buf_addr, # common->rx_bufsize, DMA_FROM_DEVICE); # return false; # } # # and it's worth noting how that first DMA sync: # # dma_sync_single_for_cpu(..DMA_FROM_DEVICE); # # is there to make sure the CPU can read the DMA buffer (possibly by # copying it from the bounce buffer area, or by doing some cache flush). # The iommu correctly turns that into a "copy from bounce bufer" so that # the driver can look at the state of the packets. # # In the meantime, the device may continue to write to the DMA buffer, but # we at least have a snapshot of the state due to that first DMA sync. # # But that _second_ DMA sync: # # dma_sync_single_for_device(..DMA_FROM_DEVICE); # # is telling the DMA mapping that the CPU wasn't interested in the area # because the packet wasn't there. In the case of a DMA bounce buffer, # that is a no-op. # # Note how it's not a sync for the CPU (the "for_device()" part), and it's # not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part). # # Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab47 # broke: it made the code bounce the buffer unconditionally, and changed # the DMA_FROM_DEVICE to just unconditionally and illogically be # DMA_TO_DEVICE. # # [ Side note: purely within the confines of the swiotlb driver it wasn't # entirely illogical: The reason it did that odd DMA_FROM_DEVICE -> # DMA_TO_DEVICE conversion thing is because inside the swiotlb driver, # it uses just a swiotlb_bounce() helper that doesn't care about the # whole distinction of who the sync is for - only which direction to # bounce. # # So it took the "sync for device" to mean that the CPU must have been # the one writing, and thought it meant DMA_TO_DEVICE. ] # # Also note how the commentary in that commit was wrong, probably due to # that whole confusion, claiming that the commit makes the swiotlb code # # "bounce unconditionally (that is, also # when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale # data from the swiotlb buffer" # # which is nonsensical for two reasons: # # - that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was # exactly when it always did - and should do - the bounce. # # - since this is a sync for the device (not for the CPU), we're clearly # fundamentally not coping back stale data from the bounce buffers at # all, because we'd be copying to the bounce buffers. # # So that commit was just very confused. It confused the direction of the # synchronization (to the device, not the cpu) with the direction of the # DMA (from the device). # # Reported-and-bisected-by: Oleksandr Natalenko <oleksandr@natalenko.name> # Reported-by: Olha Cherevyk <olha.cherevyk@gmail.com> # Cc: Halil Pasic <pasic@linux.ibm.com> # Cc: Christoph Hellwig <hch@lst.de> # Cc: Kalle Valo <kvalo@kernel.org> # Cc: Robin Murphy <robin.murphy@arm.com> # Cc: Toke Høiland-Jørgensen <toke@toke.dk> # Cc: Maxime Bizon <mbizon@freebox.fr> # Cc: Johannes Berg <johannes@sipsolutions.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 bddac7c1e02ba47f0570e494c9289acea3062cc1 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- In file included from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/tm.h:27, from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/gcc-plugin.h:31, from /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/plugin.h:23, from /kisskb/src/scripts/gcc-plugins/gcc-common.h:9, from /kisskb/src/scripts/gcc-plugins/latent_entropy_plugin.c:78: /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/../lib/gcc/aarch64-buildroot-linux-gnu/5.4.0/plugin/include/config/elfos.h:102:21: warning: invalid suffix on literal;
