2021-02-11cxgb4: collect serial config version from registerRahul Lakkireddy1-3/+0
Collect serial config version information directly from an internal register, instead of explicitly resizing VPD. v2: - Add comments on info stored in PCIE_STATIC_SPARE2 register.

2020-06-24cxgb4: move device dump arrays in header to C fileRahul Lakkireddy1-161/+0
Move all arrays related to device dump in header file to C file. Also, move the function that shares the arrays to the same C file. Fixes following warnings reported by make W=1 in several places: cudbg_entity.h:513:18: warning: 't6_hma_ireg_array' defined but not used [-Wunused-const-variable=] 513 | static const u32 t6_hma_ireg_array[][IREG_NUM_ELEM] = { Fixes: a7975a2f9a79 ("cxgb4: collect register dump") Fixes: 17b332f48074 ("cxgb4: add support to read serial flash") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S.

2020-02-25chelsio: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-4/+4
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2019-11-07cxgb4: add ETHOFLD hardware queue supportRahul Lakkireddy1-0/+3
Add support for configuring and managing ETHOFLD hardware queues. Keep the queue count and MSI-X allocation scheme same as NIC queues. ETHOFLD hardware queues are dynamically allocated/destroyed as TC-MQPRIO Qdisc offload is enabled/disabled on the corresponding interface, respectively.

S390 bpf_jit.S is removed in net-next and had changes in 'net', since that code isn't used any more take the removal. TLS data structures split the TX and RX components in 'net-next', put the new struct members from the bug fix in 'net' into the RX part. The 'net-next' tree had some reworking of how the ERSPAN code works in the GRE tunneling code, overlapping with a one-line headroom calculation fix in 'net'. Overlapping changes in __sock_map_ctx_update_elem(), keep the bits that read the prog members via READ_ONCE() into local variables before using them. Signed-off-by: David S.
