Hi All, There are quite a few popular cheap x86 devices, such as the first gen Intel Compute Stick and many many ARM boards which have sdio wifi chips. Unfortunately the mainline kernel lacks drivers for almost all sdio wifi chips, so Fedora ends up not supporting wifi on these devices, making it unattractive to run Fedora on these devices. I want to fix this and I've been thinking about how to fix this. Options are: a) A copr with kmod-s, this is not a good answer for 3 reasons: 1) It is a pain to maintain as it needs rebuilds each kernel build 2) It is not really a solution as copr does not build for ARM 3) On most of these devices wifi is the only network connectivity, so not having support on the install media makes it very hard to get wifi going to the point that an user will likely just give up b) A copr with dkms modules, this is not a good answer for 2 reasons: 1) Building kernel modules from source on the users system is ugly and more importantly fragile 2) On most of these devices wifi is the only network connectivity, so not having support on the install media makes it very hard to get wifi going to the point that an user will likely just give up c) Integrate the driver into the Fedora kernel pkg, which means that: 1) It will always be rebuild together with the kernel 2) It will be available at and directly after installation d) Get the driver upstreamed. Unfortunately many of these drivers are vendor code, which often is ported windows code with lots of ugly glue; and the effort to get this upstream will take more time then I have to invest into this. Also if this were easy it would have been done by now, there are quite a few people interested in this. With this said I know that work is being done on upstreaming esp8089 support and the rtl8xxxu maintainer is looking on extending that with sdio support solving the problem for realtek chip. Note the ETA of any of this is unclear. As such I've come to the conclusion that from a user pov the only really good solution is c. As such I would like to (for starters) add this driver: https://github.com/hadess/rtl8723bs Which is fully open source and although not ready for upstream, actively maintained by the community, to the driver/staging directory of the Fedora kernel pkg. I realize this goes against the no out-of-tree kernel modules in Fedora rule, but I believe it is time we bend that rule a bit. IIRC that rule was made to disallow so called kmod packages, which as I've listed above indeed have a bunch of downsides. However I believe that by simply integrating the driver into the fedora kernel srpm we can avoid these issues. I also believe that this rule goes against Fedora's basic principles: -It goes against the First principle, many other distros are shipping with this driver -It goes against the Features principle, disallowing people to have working wifi is a mis-Feature -It goes against the Freedom principle, if a contributor is willing to spend time to maintain such a driver he/she should have the freedom to do so I realize that this rule was made to protect the Fedora kernel maintainers from getting a lot of extra work on their plate caused by such drivers. But note that I'm not asking the Fedora kernel team to do any work on this, I'm volunteering to do both the integration work as well as maintaining these drivers going forward. If one a rebase to the next -rc1 things break, feel free to simply comment out the patch adding the driver(s) I will check each rc1 what the state is (test the driver on hardware with the specific sdio wifi chip) and fix any build or runtime issues, this is something which I'm doing anyways for my own kernel builds. All I'm asking from the fedora kernel team is permission to add the driver.
