2017-09-27ARM: tegra: Select appropriate DMA options for LPAEPaul Kocialkowski
This automatically selects options for zone DMA and 64 bit DMA addresses when LPAE is enabled on ARM Tegra platforms. These options are required for proper operation with LPAE enabled. The ZONE_DMA option is required to ensure that drivers that allocate DMA memory get buffers from the first 4 GiB. This is necessary because a lot of the controllers only support addressing 32 bits. As for ARCH_DMA_ADDR_T_64BIT, there are situations where devices that do support addresses of more than 32 bits (such as the display controller or the GPU) can run without translating addresses through an IOMMU on a device with more than 4 GiB of system memory. Note that both of these options are stop-gap solutions required only until the IOMMU can be properly integrated with the DMA mapping API and drivers use that properly and consistently.

The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.

Consider the following case: 1. NVMAP_IOC_CREATE on IOVMM gives a valid fd to user space 2. user space does not call NVMAP_IOC_ALLOC. 3. user space calls a client driver IOCTL which calls dma_buf_map_attachment 4. call to dma_buf_map_attachment propagates till__nvmap_sg_table which has heap_pgalloc as true and tries to access pages[] which has all NULL. 5. Similarly, a dma_buf_kmap() can result in __nvmap_kmap() being called which again results in NULL dereference if pages[] is accessed. A valid __nvmap_sg_table should occur only when h->alloc is true. So, add check for it. bug 1838597 bug 1883708 Change-Id: I400d9d8a94ff1003db207fc9c252b9256d796f60 Signed-off-by: Sri Krishna chowdary <schowdary@nvidia.com> Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> (cherry picked from commit 8244d104b7635cb0b26b651b6851498b9a84d7d6) Reviewed-on: http://git-master/r/1489579 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Bibek Basu <bbasu@nvidia.com> Tested-by: Bibek Basu <bbasu@nvidia.com>
