...he DMA mask properly for all platforms. Tested on both x86 and Tegra and confirmed that the DMA mask was set properly in both cases. In case there is worry about the conversion to the DMA API, here is evidence that this change is a no-op for PCI as of 4.2: http://lxr.free-electrons.com/ident?i=pci_set_dma_mask Alexandre Courbot (4): platform: allow to specify the IOMMU bit instmem/gk20a: make use of the IOMMU bit ttm: convert to DMA API ttm: set the DMA mask for platform devices drm/nouveau/include/nvkm/core/tegra.h | 3 +++ drm/nouveau/nouveau_platform.c | 14 ++++++++++++-- drm/n...

Hi all, Currently we have severe problem and are struggling to investigate it. The problem is data broken. Reproduce pocess is following, 0. test FTP function between guest domain and FTP client(other PC). 1. put data from FTP client to guest domain. 2. get data from guest domain to FTP client. 3. compare put data and get data on FTP client. 4. repeat process from step1 to step3.
