The return type of find_first_bit() is architecture specific, on ARM it is 'unsigned int', while the asm-generic code used on x86 and a lot of other architectures returns 'unsigned long'. When building the mlx5 driver on ARM, we get a warning about this: infiniband/hw/mlx5/mem.c: In function 'mlx5_ib_cont_pages': infiniband/hw/mlx5/mem.c:84:143: warning: comparison of distinct pointer types lacks a cast m = min(m, find_first_bit(&tmp, sizeof(tmp))); This patch changes the driver to use min_t to make it behave the same way on all architectures.

The new function allows updating the page tables of a memory region after it was created. This can be used to handle page faults and page invalidations. Since mlx5_ib_update_mtt will need to work from within page invalidation, so it must not block on memory allocation. It employs an atomic memory allocation mechanism that is used as a fallback when kmalloc(GFP_ATOMIC) fails. In order to reuse code from mlx5_ib_populate_pas, the patch splits this function and add the needed parameters.

This patch wraps together several changes needed for on-demand paging support in the mlx5_ib_populate_pas function, and when registering memory regions. * Instead of accepting a UMR bit telling the function to enable all access flags, the function now accepts the access flags themselves. * For on-demand paging memory regions, fill the memory tables from the correct list, and enable/disable the access flags per-page according to whether the page is present. * A new bit is set to enable writing of access flags when using the firmware create_mkey command. * Disable contig pages when on-demand paging is enabled. In addition the patch changes the UMR code to use PTR_ALIGN instead of our own macro. Signed-off-by: NHaggai Eran <haggaie@mellanox.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

When dealing with umem objects, the driver assumed host page sizes defined by PAGE_SHIFT. Modify the code to use arbitrary page shift provided by umem->page_shift to support different page sizes.

There were many places where parameters which should be u8/u16 were integer type. Additionally, in 2 places, a check for a non-null pointer was added before dereferencing the pointer (this is actually a bug fix).

This patch refactors the IB core umem code and vendor drivers to use a linear (chained) SG table instead of chunk list. With this change the relevant code becomes clearer—no need for nested loops to build and use umem.

The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
