2021-10-04qed: Add '_GTT' suffix to the IRO RAM macrosPrabhakar Kushwaha

2020-07-07net: qed: fix buffer overflow on ethtool -dAlexander Lobakin
When generating debug dump, driver firstly collects all data in binary form, and then performs per-feature formatting to human-readable if it is supported. For ethtool -d, this is roughly incorrect for two reasons. First of all, drivers should always provide only original raw dumps to Ethtool without any changes. The second, and more critical, is that Ethtool's output buffer size is strictly determined by ethtool_ops::get_regs_len(), and all data *must* fit in it. The current version of driver always returns the size of raw data, but the size of the formatted buffer exceeds it in most cases. This leads to out-of-bound writes and memory corruption. Address both issues by adding an option to return original, non-formatted debug data, and using it for Ethtool case. v2: - Expand commit message to make it more clear; - No functional changes.

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.

2019-04-14qed: Fix the DORQ's attentions handlingDenis Bolotin
Separate the overflow handling from the hardware interrupt status analysis. The interrupt status is a single register and is common for all PFs. The first PF reading the register is not necessarily the one who overflowed. All PFs must check their overflow status on every attention. In this change we clear the sticky indication in the attention handler to allow doorbells to be processed again as soon as possible, but running the doorbell recovery is scheduled for the periodic handler to reduce the time spent in the attention handler. Checking the need for DORQ flush was changed to "db_bar_no_edpm" because qed_edpm_enabled()'s result could change dynamically and might have prevented a needed flush.

2019-04-14qed: Fix missing DORQ attentionsDenis Bolotin
When the DORQ (doorbell block) is overflowed, all PFs get attentions at the same time. If one PF finished handling the attention before another PF even started, the second PF might miss the DORQ's attention bit and not handle the attention at all. If the DORQ attention is missed and the issue is not resolved, another attention will not be sent, therefore each attention is treated as a potential DORQ attention. As a result, the attention callback is called more frequently so the debug print was moved to reduce its quantity. The number of periodic doorbell recovery handler schedules was reduced because it was the previous way to mitigating the missed attention issue.

This patch adds the detection and handling of a parity error ("process kill event"), including the update of the protocol drivers, and the prevention of any HW access that will lead to device access towards the host while recovery is in progress. It also provides the means for the protocol drivers to trigger a recovery process on their decision.

2019-01-28qed: Revise load sequence to avoid PCI errorsTomer Tayar
Initiating final cleanup after an ungraceful driver unload can lead to bad PCI accesses towards the host. This patch revises the load sequence so final cleanup is sent while the internal master enable is cleared, to prevent the host accesses, and clears the internal error indications just before enabling the internal master enable.

2018-11-30qed: Use the doorbell overflow recovery mechanism in case of doorbell overflowAriel Elior
In case of an attention from the doorbell queue block, analyze the HW indications. In case of a doorbell overflow, execute a doorbell recovery. Since there can be spurious indications (race conditions between multiple PFs), schedule a periodic task for checking whether a doorbell overflow may have been missed. After a set time with no indications, terminate the periodic task.

2018-10-16qed: Align local and global PTT to propagate through the APIs.Rahul Verma
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.

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.
