2022-05-02qed: replace bitmap_weight with bitmap_empty in qed_roce_stop()Yury Norov
qed_roce_stop() calls bitmap_weight() to check if any bit of a given bitmap is set. We can do it more efficiently with bitmap_empty() because bitmap_empty() stops traversing the bitmap as soon as it finds first set bit, while bitmap_weight() counts all bits unconditionally.

2021-10-04qed: Split huge qed_hsi.h header fileOmkar Kulkarni
The qed_hsi.h is a huge header file containing HSI (Hardware Software Interface) definitions of storm memory access, debug related, general and management firmware specific. In order to have a better code-organization HSI definition, this patch split the code across multiple files, i.e. - storm memory access HSI : qed_iro_hsi.h - debug related HSI : qed_dbg_hsi.h - Management firmware HSI : qed_mfg_hsi.h - General HSI : qed_hsi.h In addition, this patch also fixes existing checkpatch warnings and few important checks.

2020-07-06net: qed: sanitize BE/LE data processingAlexander Lobakin
Current code assumes that both host and device operates in Little Endian in lots of places. While this is true for x86 platform, this doesn't mean we should not care about this. This commit addresses all parts of the code that were pointed out by sparse checker. All operations with restricted (__be*/__le*) types are now protected with explicit from/to CPU conversions, even if they're noops on common setups. I'm sure there are more such places, but this implies a deeper code investigation, and is a subject for future works.

2018-08-07qed: Add Multi-TC RoCE supportDenis Bolotin
RoCE qps use a pair of physical queues (pq) received from the Queue Manager (QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block creates a pq for each TC, and allows RoCE qps to ask for a pq with a specific TC. As a result, qps with different VLAN priorities can be mapped to different TCs, and employ features such as PFC and ETS.

2017-06-09qed*: LL2 callback operationsMichal Kalderon
LL2 today is interrupt driven - when tx/rx completion arrives [or any other indication], qed needs to operate on the connection and pass the information to the protocol-driver [or internal qed consumer]. Since we have several flavors of ll2 employeed by the driver, each handler needs to do an if-else to determine the right functionality to use based on the connection type. In order to make things more scalable [given that we're going to add additional types of ll2 flavors] move the infrastrucutre into using a callback-based approach - the callbacks would be provided as part of the connection's initialization parameters.

The CQ resource pool is protected by a spin lock. When a CQ creation fails it now deallocates under that lock as well. Signed-off-by: Ram Amrani <Ram.Amrani@cavium.com> Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-01-20qed: avoid possible stack overflow in qed_ll2_acquire_connectionArnd Bergmann
struct qed_ll2_info is rather large, so putting it on the stack can cause an overflow, as this warning tries to tell us: drivers/net/ethernet/qlogic/qed/qed_ll2.c: In function 'qed_ll2_start': drivers/net/ethernet/qlogic/qed/qed_ll2.c:2159:1: error: the frame size of 1056 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] qed_ll2_start_ooo() already uses a dynamic allocation for the structure to work around that problem, and we could do the same in qed_ll2_start() as well as qed_roce_ll2_start(), but since the structure is only used to pass a couple of initialization values here, it seems nicer to replace it with a different structure. Lacking any idea for better naming, I'm adding 'struct qed_ll2_conn', which now contains all the initialization data, and this now simply gets copied into struct qed_ll2_info rather than assigning all members one by one.

2017-01-01qed*: Update to dual-licenseMintz, Yuval
Since the submission of the qedr driver, there's inconsistency in the licensing of the various qed/qede files - some are GPLv2 and some are dual-license. Since qedr requires dual-license and it's dependent on both, we're updating the licensing of all qed/qede source files. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.
