GSoC 2017 org applications open ( sourcing interest and ideas)
by Corey W Sheldon 20 Jan '17

20 Jan '17

As some of you may know, every year Google hosts the Google Summer of Code (GSoC), last year we participated with some decent results for a few projects. I was just sending this heads up to those whom may be interested in partaking as a mentor or student (even if you are already a fedora contributor) for a project within Fedora. Basic requirements for students and ideas are below and find the full lowdown at [0]. What are the eligibility requirements for participation? * You must be at least 18 years of age * You must currently be a full or part-time student (or have been accepted for the fall term) at an accredited university as of the student acceptance date * You must be eligible to work in the country you will reside in during the program * You have not already been accepted as a Student in GSoC more than once * You must reside in a country that is not currently embargoed by the United States. See Program Rules for more information. Prospective students: read the Student Manual [1] Prospective Mentors: read the Mentors Manual [2] [0] https://developers.google.com/open-source/gsoc/faq [1] https://developers.google.com/open-source/gsoc/resources/manual#student_man… [2] https://developers.google.com/open-source/gsoc/resources/manual#mentor_manu… Hopefully I will see some of you among the applications. -- Corey W Sheldon M:703.839.6609:|:D:310.909.7672 PGP:|:0x4B1616F5BDFCC807:|:0x151D53B9C62FA404:| |:0x418E43BCA33F2A72:|:|:0xA82F0594E76CB213:|:|:0x6B4FFDF3D89BCFA5:| |:https://keybase.io/linuxmodder:|:https://ameridea.github.io:| |:https://cs.danychtech.com A goal is not always meant to be reached, it often serves simply as something to aim at. --Bruce Lee Absorb what is useful, discard what is not, add what is uniquely your own. --Bruce Lee Any man willing to sacrifice security for convenience, is deserving of neither. -- Benjamin Franklin Disclaimer: All correspondence shall be deemed of a sensitive nature, and not re-distributed without good cause or per-approval.

Adding out-of-tree wifi drivers to the Fedora kernel pkg
by Hans de Goede 20 Jan '17

20 Jan '17

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. Regards, Hans

[PATCH] Support multitouch touchpads in Surface Type Cover
by Dennis Chen 19 Jan '17

19 Jan '17

This patch adds a set of patches that are either in linux-next or headed to linux-next. Since commit 8fe89ef076fa1 ("HID: multitouch: enable the Surface 3 Type Cover to report multitouch data"), the Type Cover can be properly handled by hid-multitouch and don't require any special quirk in the kernel. These patches allow the Type Cover devices to report data with the hid-multitouch driver and expires device support with hid-microsoft.

Let me know if I can do anything to help (IMHO it would be better for you to start the discussion on this upstream since you're currently somewhat maintaining the out of tree version). On a related topic besides the kernel-driver we also need to get the firmware into linux-firmware. I expect we will be able to do this as linux-firmware already has a whole bunch of realtek firmwares but we still need to do this. Do you know who we need to contact for this ?

Right, this is exactly why I believe that it is important to have sdio wifi work out of the box on Fedora. Regards, Hans

Getting them in staging requires some commitment to them becoming mainline ready in due course. AFAICT no one is working on fixing the remaining blockers for e.g. the rtl8723bs code and the rtl8xxxu path is likely a better way forward. > The main problem I see with adding those drivers is that we still had > to have patches on top of other subsystems to get them working in 4.x > kernels. Would we still need those? No, the baytrail sdio problems have been fixed. There are still some other baytrail issues, but those happen without sdio wifi to so they are likely unrelated. > If the only reason why we cannot land this in staging is because of > indentation rules, I'd rather we made sure those rules are relaxed, > rather than reindenting everything and making it harder to rebase. As said I believe that to get these in staging we need to provide upstream with a path forward, which I believe for this specific case is adding sdio support to the rtl8xxxu driver. Which means that there is no incentive for upstream to take the rtl8723bs code into staging, as it will likely be replaced by something else rather then ever get promoted to non-staging. Also there are a bunch of other sdio wifi drivers used on ARM (mostly more realtek models) which will require significant work before being ready for staging then the rtl8723bs code, all of which will be wasted work since ultimately we plan to go the rtl8xxxu route.

Kernel 4.9 rebase plans
by Laura Abbott 14 Jan '17

14 Jan '17

Hi, Kernel 4.9 was officially released yesterday, December 11. This kernel is being built for rawhide today. The plan for bringing this kernel into F24/F25 is going to follow roughly the same schedule as in the past. This means pushing the new rebase when we think it's stable enough. In the past, this has happened around the .2 stable release (so 4.9.2 in this case). Given the holidays, this won't be happening until 2017 but we'll be monitoring closely. I'll update with more information once it gets closer. As always, please let us know if you have any questions. Thanks, Laura

Repository of Kernels for Fedora
by Benson Muite 13 Jan '17

Hi, Is there a repository of compiled linux kernels for Fedora similar to that for Ubunutu at: http://kernel.ubuntu.com/~kernel-ppa/mainline/ There are a few unofficial builds in copr, but would be helpful to know if one could change to different pre-built kernels rather than compiling for oneself. Thanks, Benson

"Work around thinkpad firmware memory layout issues and efi_mem_reserve()" fix missing from 4.9.2-200.fc25
by Hans de Goede 12 Jan '17

Hi, I was running some tests on a Thinkpad W541 this morning and I noticed that kernel-4.9.2-200.fc25 does not boot. Where as this one: https://koji.fedoraproject.org/koji/buildinfo?buildID=824906 Does boot, could it be that the patch for: "Work around thinkpad firmware memory layout issues and efi_mem_reserve()" Did not get merged when the f25 branch was bumped to 4.9.x ? Regards, Hans
