2025-05-19crypto: octeontx2 - Use dynamic allocated memory region for lmtstBharat Bhushan
Current driver uses static LMTST region allocated by firmware. Firmware allocated memory for LMTST is available in PF/VF BAR2. Using this memory have performance impact as this is mapped as device memory. There is another option to allocate contiguous memory at run time and map this in LMT MAP table with the help of AF driver. With this patch dynamic allocated memory is used for LMTST.

2025-05-19crypto: octeontx2 - Initialize cptlfs device info onceBharat Bhushan
Function otx2_cptlf_set_dev_info() initializes common fields of cptlfs data-struct. This function is called every time a cptlf is initialized but this needs be done once for a cptlf block. So this initialization is moved to early device probe code to avoid redundant initialization.

On CN10KA B0/CN10KB, CPT scatter gather format has modified to support multi-seg in inline IPsec. Due to this CPT requires new firmware and doesn't work with CN10KA0/A1 firmware. To make HW works in backward compatibility mode or works with CN10KA0/A1 firmware, a bit(T106_MODE) is introduced in HW CSR. This patch adds devlink parameter for configuring T106_MODE.

2023-12-08crypto: octeontx2 - By default allocate one CPT LF per CPT VFBharat Bhushan
There are limited number CPT LFs (example 64 LFs on cn10k) and these LFs are allocated/attached to CPT VF on its creation. cptpf sysfs parameter "kvf_limits" defines number of CPT LFs per CPT VF. Default "kvf_limits" is initialized to zero and if kvf_limits is zero then number of LF allocated are equal to online cpus in system. For example on 24 core system, 24 CPT LFs will be attached per VF. That means no CPT LF available when creating more than 2 CPT VFs on system which have total 64 LFs. Although VFs gets created but no LF attached to it. There seems no reason to default allocate as many LFs as many online cpus in system. This patch initializes "kvf_limits" to one to limit one LF allocated per CPT VF. "kvf_limits" can be changed in range of 1 to number-of-online-cpus via sysfs.

2023-05-18crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueuesTejun Heo
BACKGROUND ========== When multiple work items are queued to a workqueue, their execution order doesn't match the queueing order. They may get executed in any order and simultaneously. When fully serialized execution - one by one in the queueing order - is needed, an ordered workqueue should be used which can be created with alloc_ordered_workqueue(). However, alloc_ordered_workqueue() was a later addition. Before it, an ordered workqueue could be obtained by creating an UNBOUND workqueue with @max_active==1. This originally was an implementation side-effect which was broken by 4c16bd327c74 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered"). Because there were users that depended on the ordered execution, 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered") made workqueue allocation path to implicitly promote UNBOUND workqueues w/ @max_active==1 to ordered workqueues. While this has worked okay, overloading the UNBOUND allocation interface this way creates other issues. It's difficult to tell whether a given workqueue actually needs to be ordered and users that legitimately want a min concurrency level wq unexpectedly gets an ordered one instead. With planned UNBOUND workqueue updates to improve execution locality and more prevalence of chiplet designs which can benefit from such improvements, this isn't a state we wanna be in forever. This patch series audits all callsites that create an UNBOUND workqueue w/ @max_active==1 and converts them to alloc_ordered_workqueue() as necessary. WHAT TO LOOK FOR ================ The conversions are from alloc_workqueue(WQ_UNBOUND | flags, 1, args..) to alloc_ordered_workqueue(flags, args...) which don't cause any functional changes. If you know that fully ordered execution is not ncessary, please let me know. I'll drop the conversion and instead add a comment noting the fact to reduce confusion while conversion is in progress. If you aren't fully sure, it's completely fine to let the conversion through. The behavior will stay exactly the same and we can always reconsider later. As there are follow-up workqueue core changes, I'd really appreciate if the patch can be routed through the workqueue tree w/ your acks. Thanks.

2023-05-12crypto: octeontx2 - hardware configuration for inline IPsecSrujana Challa
On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF) handles resource allocation and configuration for PFs and their VFs. PFs request the AF directly, via mailboxes. Unlike PFs, VFs cannot send a mailbox request directly. A VF sends mailbox messages to its parent PF, with which it shares a mailbox region. The PF then forwards these messages to the AF. This patch adds code to configure inline-IPsec HW resources for CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

Plus, those three common object files are relatively big to duplicate them several times. Introduce the new module, rvu_cptcommon, to provide the common functions to both modules.

2021-06-03crypto: octeontx2 - Add mailbox support for CN10KSrujana Challa
Mailbox region configuration has some changes on CN10K platform from OcteonTX2(CN9XX) platform. On CN10K platform: The DRAM region allocated to PF is enumerated as PF BAR4 memory. PF BAR4 contains AF-PF mbox region followed by its VFs mbox region. AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR PF-VF mailbox base address is configured at RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via BAR2 indirect access. On CN9XX platform: Mailbox region in DRAM is divided into two parts AF-PF mbox region and PF-VF mbox region i.e all PFs mbox region is contiguous similarly all VFs. The base address of the AF-PF mbox region is configured at RVU_AF_PF_BAR4_ADDR. AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox size. This patch changes mbox initialization to support both CN9XX and CN10K platform. This patch also removes platform specific name from the PF/VF driver name to make it appropriate for all supported platforms.
