CE Workgroup Project Selection
|
Bird, Tim <Tim.Bird@...>
I am pleased to announce the projects to be sponsored by the CE Workgroup
for the next year. In September, the CEWG had an open project proposal period, where we solicited project ideas from the community and from workgroup members. In October, at our Architecture Group meeting, we did a technical review of these proposals, and recently the Steering Committee voted on the projects to sponsor in the coming year. Here is the list of projects that the CE working group decided to fund: 1. Setup LTSI testing/validation infrastructure 2. CPU Shielding capability 3. Device-tree documentation 4. Overwrite detection for kernel text and read-only data 5. Android boot time improvements 6. Compressed printk messages 7. Add support for CONFIG_NUMA to ARM 8. More robust UBIFS support You can see details about these project by following the links at: http://elinux.org/CEWG_Open_Project_Proposal_2013#Selected_Projects The CE Workgroup decided not to fund the following other projects. Improve UBI user space tools Implement scatter-gather lists support in UBI and UBIFS Support dumping user-space stack from kernel Kernel module binary compatibility with debug features Improve devm_* and get rid of boilerplate code Mainline synaptics touchscreen driver Add device-tree support to pn544 NFC driver Fix IRQ Domain DT support issues and gpio IRQ Generic upgrade infrastructure for embedded systems Support asymetric RSA in Crypto API Proposers and others have expressed interest in learning about the reasons why some of these were not selected. Here are some very brief notes about the reasons for not supporting a particular project: == Improve UBI user space tools Implement scatter-gather lists support in UBI and UBIFS Most CE companies are moving away from raw NAND towards eMMC for CE products. So UBIFS-related projects were not favored. One UBIFS project, dealing with robustness, however, was selected. Also, we had no bids for these projects. In the case of the scatter-gather list proposal, the main feature seemed to be to reduce memory utilization of UBIFS. No member companies seemed to have that problem. There was no indication whether scatter-gather lists might affect performance (it should improve with less data copies, but there was no data indicating any change). Support dumping user-space stack from kernel Most members thought LTTng already supported this sufficiently. If done from kernel, this would require user-space symbols in the kernel, which seemed difficult in memory-constrained devices. Also, no bid was received for this project. Kernel module binary compatibility with debug features There was concern that upstream kernel developers would break any compatibility later that was created, over time. Also, there was concern over who would maintain the support for this. Finally, there were technical issues with how to collapse and expand structures based on debug features. Improve devm_* and get rid of boilerplate code This appeared to be useful, and Wolfram produced good results in the past. However, there just wasn't enough interest in the project by the different member companies. Mainline synaptics touchscreen driver Not enough AG members used this driver to be interested in collaborating on the funding of it. The Synaptics RMI4 driver is already in the driver/input tree, just not pushed to Linus. Synaptics is planning to do another push of this, so CEWG decided to wait and see the outcome of that work. Add device-tree support to pn544 NFC driver Not enough AG members used this chip to be interested in collaborating on the funding of it. (At least, of those attending the meeting). The upstream driver is not compatible with Android, and the out-of-tree driver is not difficult to maintain, with most of the functionality residing in the user-space library. It was decided there was not enough return on investment to justify funding this work. Fix IRQ Domain DT support issues and gpio IRQ This proposal was submitted very late (well past the deadline), and there was no time to analyze it, solicit member feedback, or get bids. Generic upgrade infrastructure for embedded systems Most AG members thought that companies already had existing upgrade solutions (e.g. Android already has well-established upgrade mechanisms) Also, most members didn't think a one-size-fits-all approach would be useful. The proposal seems to be based on a particular file system layout, and doesn't handle special use cases like read-only partitions. Support asymetric RSA in Crypto API This project seemed useful, and many companies were interested. However, the only bid received was from a company that looked likely to already receive some projects this round (and they might not have the bandwidth to work on this and others.) This was rated lower priority than other projects bid upon by the same contractor. |

Yes that was the plan, you weren't mistaken. If the "status" tag looks good, then let's keep it for projects that are not selected for sponsor and add the details about it at the bottom. Something like this? http://elinux.org/Improve_UBI_user_space_tools Again, sorry for the delay... -- Ezequiel García, VanguardiaSur www.vanguardiasur.com.ar |

The status tag is good, but please add the year the item was not selected. We had a project that was rejected 2 years ago, but selected this year. Also, please put the 'non-selected' notes section in a sub-heading under 'Notes'. I've changed the Improve_UBI_user_space_tools page as an example. Can you please follow those for the other non-selected items? Thanks -- Tim |
