0faa0fe6f90ea59b10d1b0f15ce0eb0c18eff186 - nvmet: New NVMe PCI endpoint function target driver

Sat, 04 Jan 2025 05:59:50 +0100

nvmet: New NVMe PCI endpoint function target driverImplement a PCI target driver using the PCI endpoint framework. Thisrequires hardware with a PCI controller capable of executing in endpointmode.The PCI endpoint framework is used to set up a PCI endpoint functionand its BAR compatible with a NVMe PCI controller. The framework is alsoused to map local memory to the PCI address space to execute MMIOaccesses for retrieving NVMe commands from submission queues and postingcompletion entries to completion queues. If supported, DMA is used forcommand retreival and command data transfers, based on the PCI addresssegments indicated by the command using either PRPs or SGLs.The NVMe target driver relies on the NVMe target core code to executeall commands isssued by the host. The PCI target driver is mainlyresponsible for the following: - Initialization and teardown of the endpoint device and its backend PCI target controller. The PCI target controller is created using a subsystem and a port defined through configfs. The port used must be initialized with the "pci" transport type. The target controller is allocated and initialized when the PCI endpoint is started by binding it to the endpoint PCI device (nvmet_pci_epf_epc_init() function). - Manage the endpoint controller state according to the PCI link state and the actions of the host (e.g. checking the CC.EN register) and propagate these actions to the PCI target controller. Polling of the controller enable/disable is done using a delayed work scheduled every 5ms (nvmet_pci_epf_poll_cc() function). This work is started whenever the PCI link comes up (nvmet_pci_epf_link_up() notifier function) and stopped when the PCI link comes down (nvmet_pci_epf_link_down() notifier function). nvmet_pci_epf_poll_cc() enables and disables the PCI controller using the functions nvmet_pci_epf_enable_ctrl() and nvmet_pci_epf_disable_ctrl(). The controller admin queue is created using nvmet_pci_epf_create_cq(), which calls nvmet_cq_create(), and nvmet_pci_epf_create_sq() which uses nvmet_sq_create(). nvmet_pci_epf_disable_ctrl() always resets the PCI controller to its initial state so that nvmet_pci_epf_enable_ctrl() can be called again. This ensures correct operation if, for instance, the host reboots causing the PCI link to be temporarily down. - Manage the controller admin and I/O submission queues using local memory. Commands are obtained from submission queues using a work item that constantly polls the doorbells of all submissions queues (nvmet_pci_epf_poll_sqs() function). This work is started whenever the controller is enabled (nvmet_pci_epf_enable_ctrl() function) and stopped when the controller is disabled (nvmet_pci_epf_disable_ctrl() function). When new commands are submitted by the host, DMA transfers are used to retrieve the commands. - Initiate the execution of all admin and I/O commands using the target core code, by calling a requests execute() function. All commands are individually handled using a per-command work item (nvmet_pci_epf_iod_work() function). A command overall execution includes: initializing a struct nvmet_req request for the command, using nvmet_req_transfer_len() to get a command data transfer length, parse the command PRPs or SGLs to get the PCI address segments of the command data buffer, retrieve data from the host (if the command is a write command), call req->execute() to execute the command and transfer data to the host (for read commands). - Handle the completions of commands as notified by the ->queue_response() operation of the PCI target controller (nvmet_pci_epf_queue_response() function). Completed commands are added to a list of completed command for their CQ. Each CQ list of completed command is processed using a work item (nvmet_pci_epf_cq_work() function) which posts entries for the completed commands in the CQ memory and raise an IRQ to the host to signal the completion. IRQ coalescing is supported as mandated by the NVMe base specification for PCI controllers. Of note is that completion entries are transmitted to the host using MMIO, after mapping the completion queue memory to the host PCI address space. Unlike for retrieving commands from SQs, DMA is not used as it degrades performance due to the transfer serialization needed (which delays completion entries transmission).The configuration of a NVMe PCI endpoint controller is done usingconfigfs. First the NVMe PCI target controller configuration must bedone to set up a subsystem and a port with the "pci" addr_trtypeattribute. The subsystem can be setup using a file or block devicebacked namespace or using a passthrough NVMe device. After this, thePCI endpoint can be configured and bound to the PCI endpoint controllerto start the NVMe endpoint controller.In order to not overcomplicate this initial implementation of anendpoint PCI target controller driver, protection information is notfor now supported. If the PCI controller port and namespace areconfigured with protection information support, an error will bereturned when the controller is created and initialized when theendpoint function is started. Protection information support will beadded in a follow-up patch series.Using a Rock5B board (Rockchip RK3588 SoC, PCI Gen3x4 endpointcontroller) with a target PCI controller setup with 4 I/O queues and anull_blk block device as a namespace, the maximum performance using fiowas measured at 131 KIOPS for random 4K reads and up to 2.8 GB/Sthroughput. Some data points are:Rnd read, 4KB, QD=1, 1 job : IOPS=16.9k, BW=66.2MiB/s (69.4MB/s)Rnd read, 4KB, QD=32, 1 job : IOPS=78.5k, BW=307MiB/s (322MB/s)Rnd read, 4KB, QD=32, 4 jobs: IOPS=131k, BW=511MiB/s (536MB/s)Seq read, 512KB, QD=32, 1 job : IOPS=5381, BW=2691MiB/s (2821MB/s)The NVMe PCI endpoint target driver is not intended for production use.It is a tool for learning NVMe, exploring existing features and testingimplementations of new NVMe features.Co-developed-by: Rick Wertenbroek Signed-off-by: Damien Le Moal Reviewed-by: Christoph Hellwig Reviewed-by: Manivannan Sadhasivam Tested-by: Manivannan Sadhasivam Reviewed-by: Krzysztof Wilczyński Signed-off-by: Keith Busch List of files: /linux/drivers/nvme/target/Makefile
