This should be handled under the hood without the driver even knowing.

[PATCH RFC v1 0/7] swiotlb: extra 64-bit buffer for dev->dma_io_tlb_mem

Hello, I used to send out a patchset on 64-bit buffer and people thought it was the same as Restricted DMA. However, the 64-bit buffer is still not supported. https://lore.kernel.org/all/20210203233709.19819-1-dongli.zh...@oracle.com/ This RFC is to introduce the extra swiotlb buffer with SWIOTL

[PATCH RFC v1 3/7] swiotlb-xen: support highmem for xen specific code

While for most of times the swiotlb-xen relies on the generic swiotlb api to initialize and use swiotlb, this patch is to support highmem swiotlb for swiotlb-xen specific code. E.g., the xen_swiotlb_fixup() may request the hypervisor to provide 64-bit memory pages as swiotlb buffer. Cc: Konrad Wi

[PATCH RFC v1 1/7] swiotlb: introduce the highmem swiotlb buffer

Currently, the virtio driver is not able to use 4+ GB memory when the swiotlb is enforced, e.g., when amd sev is involved. Fortunately, the SWIOTLB_ANY flag has been introduced since commit 8ba2ed1be90f ("swiotlb: add a SWIOTLB_ANY flag to lift the low memory restriction") to allocate swiotlb buff

[PATCH RFC v1 7/7] swiotlb: fix the slot_addr() overflow

Since the type of swiotlb slot index is a signed integer, the "((idx) << IO_TLB_SHIFT)" will returns incorrect value. As a result, the slot_addr() returns a value which is smaller than the expected one. E.g., the 'tlb_addr' generated in swiotlb_tbl_map_single() may return a value smaller than the

[PATCH RFC v1 2/7] swiotlb: change the signature of remap function

Add new argument 'high' to remap function, so that it will be able to remap the swiotlb buffer based on whether the swiotlb is 32-bit or 64-bit. Currently the only remap function is xen_swiotlb_fixup(). Cc: Konrad Wilk Cc: Joe Jin Signed-off-by: Dongli Zhang --- arch/x86/include/asm/xen/swiot

[PATCH RFC v1 6/7] virtio: use io_tlb_high_mem if it is active

When the swiotlb is enforced (e.g., when amd sev is involved), the virito driver will not be able to use 4+ GB memory. Therefore, the virtio driver uses 'io_tlb_high_mem' as swiotlb. Cc: Konrad Wilk Cc: Joe Jin Signed-off-by: Dongli Zhang --- drivers/virtio/virtio.c | 8 1 file change

[PATCH RFC v1 4/7] swiotlb: to implement io_tlb_high_mem

This patch is to implement the extra 'io_tlb_high_mem'. In the future, the device drivers may choose to use either 'io_tlb_default_mem' or 'io_tlb_high_mem' as dev->dma_io_tlb_mem. The highmem buffer is regarded as active if (high_nslabs && io_tlb_high_mem.nslabs) returns true. Cc: Konrad Wilk C

[PATCH RFC v1 5/7] swiotlb: add interface to set dev->dma_io_tlb_mem
