swiotlb: optimize get_max_slots() (2023-08-08 10:29:21 -0700)
----------------------------------------------------------------
dma-maping updates for Linux 6.6
- allow dynamic sizing of the swiotlb buffer, to cater for secure
virtualization workloads that require all I/O to be bounce buffered
(Petr Tesarik)
- move a declaration to a header (Arnd Bergmann)
- check for memory region overlap in dma-contiguous (Binglei Wang)
- remove the somewhat dangerous runtime swiotlb-xen enablement and
unexport is_swiotlb_active (Christoph Hellwig, Juergen Gross)
- per-node CMA improvements (Yajun Deng)
----------------------------------------------------------------
Arnd Bergmann (1):
dma-mapping: move arch_dma_set_mask() declaration to header
Binglei Wang (1):
dma-contiguous: check for memory region overlap
Christoph Hellwig (2):
x86: always initialize xen-swiotlb when xen-pcifront is enabling
swiotlb: unexport is_swiotlb_active
Juergen Gross (1):
xen/pci: add flag for PCI passthrough being possible
Petr Tesarik (11):
swiotlb: bail out of swiotlb_init_late() if swiotlb is already allocated
swiotlb: make io_tlb_default_mem local to swiotlb.c
swiotlb: add documentation and rename swiotlb_do_find_slots()
swiotlb: separate memory pool data from other allocator data
swiotlb: add a flag whether SWIOTLB is allowed to grow
swiotlb: if swiotlb is full, fall back to a transient memory pool
swiotlb: determine potential physical address limit
swiotlb: allocate a new memory pool when existing pools are full
swiotlb: search the software IO TLB only if the device makes use of it
swiotlb: move slot allocation explanation comment where it belongs
swiotlb: optimize get_max_slots()
Yajun Deng (2):
dma-contiguous: support per-numa CMA for all architectures
dma-contiguous: support numa CMA for specified node
