* ASoC: amd: acp3x: use dma address for acp3x dma driverVijendar Mukunda2019-08-021-9/+5
| | | | | | | | | | | | | | | We shouldn't assume CPU physical address we get from page_to_phys() is same as DMA address we get from dma_alloc_coherent(). On x86_64, we won't run into any problem with the assumption when dma_ops is nommu_dma_ops. However, DMA address is IOVA when IOMMU is enabled. And it's most likely different from CPU physical address when AMD IOMMU is not in passthrough mode. This patch fixes page faults when IOMMU is enabled.

Pass struct device of the parent to snd_pcm_lib_preallocate_pages() so dma_alloc_coherent() can use correct dma_ops. Otherwise, it will use default dma_ops which is nommu_dma_ops on x86_64 even when IOMMU is enabled and set to non passthrough mode.

Also, notice that it makes no sense to allocate any resources if res = platform_get_resource(pdev, IORESOURCE_MEM, 0); fails, so move the call to devm_kzalloc() below the mentioned code. Lastly, improve the use of sizeof in the call to devm_kzalloc() by changing it from sizeof(struct i2s_dev_data) to sizeof(*adata) This issue was detected with the help of Coccinelle.

* ASoC: use dma_ops of parent device for acp_audio_dmaYu Zhao2018-12-061-2/+5
| | | | | | | | | | | | | | | | | | | | | | | AMD platform device acp_audio_dma can only be created by parent PCI device driver (drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c). Pass struct device of the parent to snd_pcm_lib_preallocate_pages() so dma_alloc_coherent() can use correct dma_ops. Otherwise, it will use default dma_ops which is nommu_dma_ops on x86_64 even when IOMMU is enabled and set to non passthrough mode. Though platform device inherits some dma related fields during its creation in mfd_add_device(), we can't simply pass its struct device to snd_pcm_lib_preallocate_pages() because dma_ops is not among the inherited fields. Even it were, drivers/iommu/amd_iommu.c would ignore it because get_device_id() doesn't handle platform device. This change shouldn't give us any trouble even struct device of the parent becomes null or represents some non PCI device in the future, because get_dma_ops() correctly handles null struct device or uses the default dma_ops if struct device doesn't have it set.

* ASoC: AMD: Make ACP->SYSMEM DMA non circularAkshu Agrawal2018-08-061-5/+31
| | | | | | | | | | In capture case we don't want ACP to SYSMEM dma to be circular. This is because if an in place DSP filter is applied to captured output then circular DMA can overwrite the filter value with stale data.
