Switch to contigmalloc in the Hyper-V code 2023-06-06T09:50:59+00:00 Andrew Turner andrew@FreeBSD.org 2023-05-22T18:52:54+00:00 62f9bcf2b4271d58ccf0bd8a81c540bb99a53ef7 In the Hyper-V drivers we need to allocate buffers shared between the host and guest. This memory has been allocated with bus_dma, however it doesn't use this correctly, e.g. it is missing calls to bus_dmamap_sync. Along with this on arm64 we need this memory to be mapped with the correct memory type that bus_dma may not use. Switch to contigmalloc to allocate this memory as this will correctly allocate cacheable memory.
