qed: introduce qed_chain_get_elem_used{,u32}()

2020-07-23T01:19:03+00:00

Add reverse-variants of qed_chain_get_elem_left{,u32}() to be able to know current chain occupation. They will be used in the upcoming qede XDP_REDIRECT code. They share most of the logics with the mentioned ones, so were reused to collapse the latters.

qed: optimize common chain accessors

2020-07-23T01:19:03+00:00

Constify chain pointers and refactor qed_chain_get_elem_left{,u32}() a bit. Signed-off-by: Alexander Lobakin Signed-off-by: Igor Russkikh Signed-off-by: Michal Kalderon Signed-off-by: David S. Miller

qed: add support for different page sizes for chains

2020-07-23T01:19:03+00:00

Extend current infrastructure to store chain page size in a struct and use it in all functions instead of fixed QED_CHAIN_PAGE_SIZE. Its value remains the default one, but can be overridden in qed_chain_init_params before chain allocation.

qed: simplify chain allocation with init params struct

2020-07-23T01:19:03+00:00

To simplify qed_chain_alloc() prototype and call sites, introduce struct qed_chain_init_params to specify chain params, and pass a pointer to filled struct to the actual qed_chain_alloc() instead of a long list of separate arguments.

qed: move chain initialization inlines next to allocation functions

2020-07-23T01:19:03+00:00

qed_chain_init*() are used in one file/place on "cold" path only, so they can be uninlined and moved next to the call sites. Signed-off-by: Alexander Lobakin Signed-off-by: Igor Russkikh Signed-off-by: Michal Kalderon Signed-off-by: David S. Miller

qed: sanitize PBL chains allocation

2020-07-23T01:19:03+00:00

PBL chain elements are actually DMA addresses stored in __le64, but currently their size is hardcoded to 8, and DMA addresses are assigned via cast to variable-sized dma_addr_t without any bitwise conversions. Change the type of pbl_virt array to match the actual one, add a new field to store the size of allocated DMA memory and sanitize elements assignment. Misc: give more logic names to the members of qed_chain::pbl_sp embedded struct. Signed-off-by: Alexander Lobakin Signed-off-by: Igor Russkikh Signed-off-by: Michal Kalderon Signed-off-by: David S.

qed: reformat "qed_chain.h" a bit

Reformat structs and macros definitions a bit prior to making functional changes. Signed-off-by: Alexander Lobakin Signed-off-by: Igor Russkikh Signed-off-by: Michal Kalderon Signed-off-by: David S. Miller
