== Migrate NAND driver to new exec_op framework == |
| Line 33: | Line 34: |
| Workqueue is an asynchronous execution mechanism which is widely used across the kernel. A work item queued on a workqueue is asynchronously executed by a worker task (kworker/* in ps output). It's used for various purposes from simple context bouncing to hosting a persistent in-kernel service thread. | ''Mentor:'': [[ Eze Garcia|]] |
| Line 35: | Line 36: |
| Due to its development history, there currently are two sets of interfaces to create workqueues. | === Major task === |
| Line 37: | Line 38: |
| * create[_singlethread|_freezable]_workqueue() * alloc[_ordered]_workqueue() |
Recently, a new NAND framework called "exec_op" was introduced, which sends specific NAND operations to a device, via a single ->exec_o() callback. |
| Line 40: | Line 40: |
| The latter is the new interface which is superset of the former. While each create*_workqueue() can be directly mapped to an alloc*_workqueue() invocation, create*_workqueue() encodes much less information than alloc*_workqueue() making determining which exact flavor and attributes to use non-trivial. Each case should be examined to find out why a specific kind is used and then converted to an alloc*_workqueue() invocation which matches the requirements. | Its goal is to ease the support of complex NAND controllers, while also supporting legacy devices. In other words, it's meant to eventually replace ->cmd_ctrl(), ->cmdfunc() and ->read/write_byte/word/buf() hooks. Currently, a few drivers have been already converted, and others are in the process of being converted. However, many drivers will remain to be converted, some conversions being more complex than others. The goal of this project is to convert one or more NAND device drivers, removing the ->cmd_ctrl() uses and use ->exec_op() instead. |
| Line 42: | Line 44: |
| There currently are around 280 users of the legacy interface. While the number seems daunting, there are common patterns that many of them follow. | The selected intern will learn generic skills on Linux device drivers development. Also, they will learn specific skills about NAND technology, general MTD support in Linux and the new NAND framework. |
| Line 44: | Line 46: |
| This project would involve understanding workqueue's various users to certain degree in addition to workqueue itself and can be a good opportunity to roam through and learn various parts of the kernel. | === Small tasks === |

| Brief project description. | nftables provides a replacement for the very popular {ip,ip6,arp,eb}tables tools. nftables reuses most of the Netfilter components such as the existing hooks, connection tracking system, NAT, userspace queueing, logging among many other features. So we have only replaced the packet classification framework. nftables comes with a new userspace utility ''nft'' and the low-level userspace library ''libnftnl''.
