2024-11-26octeontx2-af: Quiesce traffic before NIX block resetHariprasad Kelam
During initialization, the AF driver resets all blocks. The RPM (MAC) block and NIX block operate on a credit-based model. When the NIX block resets during active traffic flow, it doesn't release credits to the RPM block. This causes the RPM FIFO to overflow, leading to receive traffic struck. To address this issue, the patch introduces the following changes: 1. Stop receiving traffic at the MAC level during AF driver initialization. 2. Perform an X2P reset (prevents RXFIFO of all LMACS from pushing data) 3. Reset the NIX block. 4. Clear the X2P reset and re-enable receiving traffic.

2024-11-26octeontx2-af: RPM: Fix low network performanceHariprasad Kelam
Low network performance is observed even on RPMs with larger FIFO lengths. The cn10kb silicon has three RPM blocks with the following FIFO sizes: -------------------- | RPM0 | 256KB | | RPM1 | 256KB | | RPM2 | 128KB | -------------------- The current design stores the FIFO length in a common structure for all RPMs (mac_ops). As a result, the FIFO length of the last RPM is applied to all RPMs, leading to reduced network performance. This patch resolved the problem by storing the fifo length in per MAC structure (cgx).

2022-12-07octeontx2-af: cn10kb: Add RPM_USX MAC supportHariprasad Kelam
OcteonTx2's next gen platform the CN10KB has RPM_USX MAC which has a different serdes when compared to RPM MAC. Though the underlying HW is different, the CSR interface has been designed largely inline with RPM MAC, with few exceptions though. So we are using the same CGX driver for RPM_USX MAC as well and will have a different set of APIs for RPM_USX where ever necessary. The RPM and RPM_USX blocks support a different number of LMACS. RPM_USX support 8 LMACS per MAC block whereas legacy RPM supports only 4 LMACS per MAC. with this RPM_USX support double the number of DMAC filters and fifo size. This patch adds initial support for CN10KB's RPM_USX MAC i.e registering the driver and defining MAC operations (mac_ops). Adds the logic to configure internal loopback and pause frames and assign FIFO length to LMACS. Kernel reads lmac features like lmac type, autoneg, etc from shared firmware data this structure only supports 4 lmacs per MAC, this patch extends this structure to accommodate 8 lmacs.

2022-12-07octeontx2-af: Support variable number of lmacsRakesh Babu Saladi
Most of the code in CGX/RPM driver assumes that max lmacs per given MAC as always, 4 and the number of MAC blocks also as 4. With this assumption, the max number of interfaces supported is hardcoded to 16. This creates a problem as next gen CN10KB silicon MAC supports 8 lmacs per MAC block. This patch solves the problem by using "max lmac per MAC block" value from constant csrs and uses cgx_cnt_max value which is populated based number of MAC blocks supported by silicon.

2021-02-11octeontx2-af: cn10k: Add support for programmable channelsSubbaraya Sundeep
NIX uses unique channel numbers to identify the packet sources/sinks like CGX,LBK and SDP. The channel numbers assigned to each block are hardwired in CN9xxx silicon. The fixed channel numbers in CN9xxx are: 0x0 | a << 8 | b - LBK(0..3)_CH(0..63) 0x0 | a << 8 - Reserved 0x700 | a - SDP_CH(0..255) 0x800 | a << 8 | b << 4 | c - CGX(0..7)_LMAC(0..3)_CH(0..15) All the channels in the above fixed enumerator(with maximum number of blocks) are not required since some chips have less number of blocks. For CN10K silicon the channel numbers need to be programmed by software in each block with the base channel number and range of channels. This patch calculates and assigns the channel numbers to efficiently distribute the channel number range(0-4095) among all the blocks. The assignment is made based on the actual number of blocks present and also contiguously leaving no holes. The channel numbers remaining after the math are used as new CPT replay channels present in CN10K. Also since channel numbers are not fixed the transmit channel link number needed by AF consumers is calculated by AF and sent along with nix_lf_alloc mailbox response.

2020-03-02octeontx2-af: Optimize data retrieval from firmwareLinu Cherian
For retrieving info like interface MAC addresses, packet parser key extraction config etc currently a command is sent to firmware and firmware which periodically polls for commands, processes these and returns the info. This is resulting in interface initialization taking lot of time. To optimize this a memory region is shared between firmware and this driver, firmware while booting puts static info like these into that region for driver to read directly without using commands. With this - Logic for retrieving packet parser extraction config via commands is removed and repalced with using the shared 'fwdata' structure. - Now RVU MSIX vector address is also retrieved from this fwdata struct instead of from CSR. Otherwise when kexec/kdump crash kernel loads CSR will have a IOVA setup by primary kernel which impacts RVU PF/VF's interrupts. - Also added a mbox handler for PF/VF interfaces to retrieve their MAC addresses from AF.

To support above - Mbox messaging support for sending msgs from AF to PF has been added. - Added mbox msgs so that PFs can register/unregister for link events. - Link notifications are sent to PF under two scenarioss. 1. When a asynchronous link change notification is received from firmware with notification flag turned on for that PF. 2. Upon notification turn on request, the current link status is send to the PF. Also added a new mailbox msg using which RVU PF/VF can retrieve their mapped CGX LMAC's current link info. Link info includes status, speed, duplex and lmac type.

2018-10-17octeontx2-af: Support for MAC address filters in CGXVidhya Raman
This patch adds support for setting MAC address filters in CGX for PF interfaces. Also PF interfaces can be put in promiscuous mode. Dataplane PFs access this functionality using mailbox messages to the AF driver.

2018-10-17octeontx2-af: Support to retrieve CGX LMAC statsChristina Jacob

2018-10-17octeontx2-af: CGX Rx/Tx enable/disable mbox handlersSunil Goutham

2018-10-10octeontx2-af: Add support for CGX link managementLinu Cherian
CGX LMAC initialization, link status polling etc is done by low level secure firmware. For link management this patch adds a interface or communication mechanism between firmware and this kernel CGX driver. - Firmware interface specification is defined in cgx_fw_if.h. - Support to send/receive commands/events to/form firmware. - events/commands implemented * link up * link down * reading firmware version Signed-off-by: Linu Cherian <lcherian@marvell.com> Signed-off-by: Nithya Mani <nmani@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2018-10-10octeontx2-af: Set RVU PFs to CGX LMACs mappingLinu Cherian
Each of the enabled CGX LMAC is considered a physical interface and RVU PFs are mapped to these. VFs of these SRIOV PFs will be virtual interfaces and share CGX LMAC along with PF. This mapping info will be used later on for Rx/Tx pkt steering.

2018-10-10octeontx2-af: Add Marvell OcteonTX2 CGX driverSunil Goutham
This patch adds basic template for Marvell OcteonTX2's CGX ethernet interface driver. Just the probe. RVU AF driver will use APIs exported by this driver for various things like PF to physical interface mapping, loopback mode, interface stats etc. Hence marged both drivers into a single module.
