As explained by Robin Murphy: > the IOMMU shutdown disables paging, so if the VOP is still > scanning out then that will result in whatever IOVAs it was using now going > straight out onto the bus as physical addresses. We had a more radical approach before in commit 7f3ef5de ("drm/rockchip: Allow driver to be shutdown on reboot/kexec") but that resulted in new warnings and oopses on shutdown on rk3399 chromeos devices. So second try is resurrecting Vicentes shutdown change which should achieve the same result but in a less drastic way.

Add binding for the LG ACX467AKM-7 4.95" 1080×1920 LCD panel that is found on the LG Nexus 5 (hammerhead) phone. This appears to be a JDI panel based on some Internet searches, however a specific model number could not be found. I disassembled an old Nexus 5 with a broken screen and the LG part number is the only model number present on the back of the panel, so I think that is probably the best ID to use. Signed-off-by:

The GFX IP is inside of the ASPEED BMC SoC so there is little use enabling it on a kernel that does not support ASPEED. When building with COMPILE_TEST the architecture many not have CMA support, so to avoid breaking the build we only select these options if the architecture supports the contiguous allocator. I suspect the DRM_PANEL came from a cut/paste error. Fixes: 4f2a8f58 ("drm: Add ASPEED GFX driver") Reported-by:

Add support for 2MB sized pages. This will improve our map and unmap times and save a bit of memory by avoiding 3rd level page tables for contiguous allocations. As we use shmem for buffers and huge page allocations for shmem are off by default, there isn't an improvement out of the box and userspace must enable THP for shmem. It's not clear if the h/w can support 1GB page sizes which standard ARM long format descriptors support. In any case, it is unlikely we'll see any contiguous 1GB allocations on current h/w.

ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but have a few differences. Add a new format type to represent the format. The input address size is 48-bits and the output address size is 40-bits (and possibly less?). Note that the later bifrost GPUs follow the standard 64-bit stage 1 format. The differences in the format compared to 64-bit stage 1 format are: The 3rd level page entry bits are 0x1 instead of 0x3 for page entries. The access flags are not read-only and unprivileged, but read and write. This is similar to stage 2 entries, but the memory attributes field matches stage 1 being an index. The nG bit is not set by the vendor driver. This one didn't seem to matter, but we'll keep it aligned to the vendor driver. Cc: Will Deacon <will.deacon@arm.com> Acked-by:

Now that we can express our DMA topology, rely on those property instead of hardcoding an offset from the dma_addr_t which wasn't really great. We still need to add some code to deal with the old DT that would lack that property, but we move the offset to the DRM device dma_pfn_offset to be able to rely on just the dma_addr_t associated to the GEM object.
