2020-01-27qed: FW 8.42.2.0 Additional ll2 typeMichal Kalderon1-1/+4
LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue. This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation which didn't have an effect in other use cases.

This patch refactors the current llh implementation. It exposes a hw resource called ppfid (port-pfid) and implements an API for configuring the resource. Default configuration which was used until now limited the number of filters per PF and did not support engine affinity per protocol. The new API enables allocating more filter rules per PF and enables affinitizing protocol packets to a certain engine which enables full 100g protocol offload support.

2018-10-16qed: Align local and global PTT to propagate through the APIs.Rahul Verma1-15/+12
Align the use of local PTT to propagate through the qed_mcp* API's. Global ptt should not be used. Register access should be done through layers. Register address is mapped into a PTT, PF translation table. Several interface functions require a PTT to direct read/write into register. There is a pool of PTT maintained, and several PTT are used simultaneously to access device registers in different flows. Same PTT should not be used in flows that can run concurrently. To avoid running out of PTT resources, too many PTT should not be acquired without releasing them. Every PF has a global PTT, which is used throughout the life of PF, in most important flows for register access. Generic functions acquire the PTT locally and release after the use. This patch aligns the use of Global PTT and Local PTT accordingly. Signed-off-by: Rahul Verma <rahul.verma@cavium.com> Signed-off-by: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

Currently driver registers to physical link notifications (of the device) from Management firmware (MFW). Driver doesn't get notified if there's a change in the virtual link e.g., link-flap on the peer PF interface. Virtual link indication from MFW reflects the per PF link status instead of the physical link.

Keep sending mailbox commands to the MFW when it is not responsive ends up with a redundant amount of timeout expiries.

2018-08-20qed: Prevent a possible deadlock during driver load and unloadTomer Tayar1-12/+31
The MFW manages an internal lock to prevent concurrent hardware (de)initialization of different PFs. This, together with the busy-waiting for the MFW's responses for commands, might lead to a deadlock during concurrent load or unload of PFs.

2018-07-22qed: Fix link flap issue due to mismatching EEE capabilities.Sudarsana Reddy Kalluru1-3/+9
Apparently, MFW publishes EEE capabilities even for Fiber-boards that don't support them, and later since qed internally sets adv_caps it would cause link-flap avoidance (LFA) to fail when driver would initiate the link. This in turn delays the link, causing traffic to fail. Driver has been modified to not to ask MFW for any EEE config if EEE isn't to be enabled.

2018-06-13treewide: kmalloc() -> kmalloc_array()Kees Cook1-3/+3
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

This patch adds driver changes for supporting the Unified Fabric Port (UFP).
