2019-01-04qed: Fix qed_chain_set_prod() for PBL chains with non power of 2 page countDenis Bolotin1-0/+31
In PBL chains with non power of 2 page count, the producer is not at the beginning of the chain when index is 0 after a wrap. Therefore, after the producer index wrap around, page index should be calculated more carefully.

2017-06-20qed: Chain support for external PBLMintz, Yuval1-0/+7
iWARP would require the chains to allocate/free their PBL memory independently, so add the infrastructure to provide it externally. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-01qed*: Update to dual-licenseMintz, Yuval1-5/+29
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.

2016-11-30qed: Optimize qed_chain datapath usageMintz, Yuval1-64/+80
The chain structure and functions are widely used by the qed* modules, both for configuration and datapath. E.g., qede's Tx has one such chain and its Rx has two. Currently, the strucutre's fields which are required for datapath related functions [produce/consume] are intertwined with fields which are required only for configuration purposes [init/destroy/etc.]. This patch re-arranges the chain structure so that all the fields which are required for datapath usage could reside in a single cacheline instead of the two which are required today.

2016-08-19qed: utilize FW 8.10.10.0Yuval Mintz1-13/+0
This new firmware for the qed* adpaters fixes several issues: - Better blocking of malicious VFs. - After FLR, Tx-switching [internal routing] of packets might be incorrect. - Deletion of unicast MAC filters would sometime have side-effect of corrupting the MAC filters configred for a device. It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities. This would also bump the qed* driver versions to 8.10.9.20. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-03qed: Fix next-ptr chains for BE / 32-bitYuval Mintz1-2/+1
Commit a91eb52abb50 ("qed: Revisit chain implementation") contains an incorrect implementation for BE platforms, as device's regpairs containing addresses are LE and they're not converted correctly when read back. In addition, it raises a compilation warning for 32-bit platforms where dma_addr_t is a 32-bit variable.

2016-06-03qed: Revisit chain implementationYuval Mintz1-219/+334
RoCE driver is going to need a 32-bit chain [current chain implementation for qed* currently supports only 16-bit producer/consumer chains]. This patch adds said support, as well as doing other slight tweaks and modifications to qed's chain API. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

2016-02-21qed: Introduce DMA_REGPAIR_LEYuval Mintz1-0/+4
FW hsi contains regpairs, mostly for 64-bit address representations. Since same paradigm is applied each time a regpair is filled, this introduces a new utility macro for setting such regpairs. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-12-07qed: Fix corner case for chain in-between pagesTomer Tayar1-1/+2
The amount of chain next pointer elements between the producer and the consumer indices depends on which pages they currently point to. The current calculation is based only on their difference, and it can lead to a number of free elements which is higher by 1 than the actual value.

2015-10-27qed: Add module with basic common supportYuval Mintz1-0/+539
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
