Wait longer :) I'm still chasing bugs in 4.20-rc2, I haven't started merging many patches for 4.21 yet. Your patches are tracked in patchwork here: https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=75253 If they're still in "new" state around rc5 then feel free to ping me again. cheers >> diff --git a/arch/powerpc/platforms/pasemi/dma_lib.c >> b/arch/powerpc/platforms/pasemi/dma_lib.c >> index 53384eb..d18d164 100644 >> --- a/arch/powerpc/platforms/pasemi/dma_lib.c >> +++ b/arch/powerpc/platforms/pasemi/dma_lib.c >> @@ -255,15 +255,13 @@ int pasemi_dma_alloc_ring(struct pasemi_dmachan *chan, >> int ring_size) >> >> chan->ring_size = ring_size; >> >> - chan->ring_virt = dma_alloc_coherent(&dma_pdev->dev, >> + chan->ring_virt = dma_zalloc_coherent(&dma_pdev->dev, >> ring_size * sizeof(u64), >> &chan->ring_dma, GFP_KERNEL); >> >> if (!chan->ring_virt) >> return -ENOMEM; >> >> - memset(chan->ring_virt, 0, ring_size * sizeof(u64)); >> - >> return 0; >> } >> EXPORT_SYMBOL(pasemi_dma_alloc_ring); >> -- >> 2.7.4 >>
