2020-09-09drm: allow limiting the scatter list size.Gerd Hoffmann1-1/+1
Add drm_device argument to drm_prime_pages_to_sg(), so we can call dma_max_mapping_size() to figure the segment size limit and call into __sg_alloc_table_from_pages() with the correct limit. This fixes virtio-gpu with sev. Possibly it'll fix other bugs too given that drm seems to totaly ignore segment size limits so far ... v2: place max_segment in drm driver not gem object. v3: move max_segment next to the other gem fields. v4: just use dma_max_mapping_size().

2020-07-13drm: radeon: fix common struct sg_table related issuesMarek Szyprowski1-6/+5
The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function returns the number of the created entries in the DMA address space. However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

2020-07-08gpu/drm: Remove debug info about CPU addressTiezhu Yang1-2/+2
When I update the latest kernel, I see the following "____ptrval____" boot messages. [ 1.872600] radeon 0000:01:05.0: fence driver on ring 0 use gpu addr 0x0000000048000c00 and cpu addr 0x(____ptrval____) [ 1.879095] radeon 0000:01:05.0: fence driver on ring 5 use gpu addr 0x0000000040056038 and cpu addr 0x(____ptrval____) Both radeon_fence_driver_start_ring() and amdgpu_fence_driver_start_ring() have the similar issue, there exists the following two methods to solve it: (1) Use "%pK" instead of "%p" so that the CPU address can be printed when the kptr_restrict sysctl is set to 1. (2) Just completely drop the CPU address suggested by Christian, because the CPU address was useful in the past, but isn't any more. We now have a debugfs file to read the current fence values. Since the CPU address is not much useful, just remove the debug info about CPU address.

2020-07-01drm/radeon: fix array out-of-bounds read and write issuesColin Ian King1-1/+1
There is an off-by-one bounds check on the index into arrays table->mc_reg_address and table->mc_reg_table_entry[k].mc_data[j] that can lead to reads and writes outside of arrays. Fix the bound checking off-by-one error.
