  • 1cd258d7f   cxl: Add new header for call backs and structs ... Browse Code »

    This new header adds callbacks and structs needed by the rest of the kernel to
    hook into the cxl infrastructure.

    This adds the cxl_ctx_in_use() function for use in the mm code to see if any
    cxl contexts are currently in use. This is used by the tlbie() to determine if
    it can do local TLB invalidations or not. This also adds get/put calls for the
    cxl driver module to refcount the active cxl contexts.

    cxl_ctx_get/put/in_use are static inlined here as they are called in tlbie
    which we want to be fast (mpe's suggestion).

    Empty functions are provided when CONFIG_CXL_BASE is not enabled.
