They aren't included at the end of your message. I forgot to add them. [3] It was about Radeon driver but I didn't find a precise reference. I vaguely remember some text about it in their wiki, but It doesn't seem to be there anymore. So take that with a grain of salt. [4] This is the I.MX SDMA driver for several I.MX SOCs, as shown by this commit: 70dabaede806 dma: imx-sdma: Assign a default script number for ROM firmware cases "i.MX series have inner firmware in its ROM code: when SDMA isn't provided any firmware from Kernel or rootfs, the default inner ROM firmware will be activated."

There are two different projects: - Linux: This is where the changes that can be upstreamed goes - Linux-libre: This is where the deblob happens. Depending on the people and the drivers involved, upstream may be against making the driver work without a non-free firmware[3] for some drivers, or, for other drivers, might want it to also work without the firmware[4]. There is some work to do in that area to make devices drivers work without nonfree firmwares, either by making the driver work without it or by replacing the nonfree firmware with free software. There is a Libreplanet wiki page with some details about this[1], but it doesn't have much details on what can be done to improve the situation. There is another page[2] that has more information on what can be done to improve freedom with technical work. This includes many projects that benefits from having such skills (kernel development).

IIRC we talked on IRC shortly after you sent email (I recall seeing the message coming into my inbox, but I didn't manage to find it again; I didn't think of looking for it in the folder that holds email for i...@fsfla.org, since it's so unrelated with general requests for information from the organization), but if I'm mistaken, I apologize for the long delay in responding. We don't make changes to Linux other than the minimal ones required to make it FSDG-compliant. Any other sort of development should go upstream; our deblobbing infrastructure is not compatible with maintaining other kinds of local patches, which is fine because our goal is to keep divergence to a minimum. Now, maybe in your last paragraph you're not asking about developing the kernel, but rather developing userland applications for the kernel. The good news is that the userland/kernel interfaces are not changed in any way, so userland development for GNU Linux-libre is no different from userland development for non-Free Linux. Except for the joy of using a kernel that respects your freedom ;-) -- Alexandre Oliva, freedom fighterhttp://FSFLA.org/~lxoliva/ You must be the change you wish to see in the world. -- Gandhi Be Free! -- http://FSFLA.org/ FSF Latin America board member Free Software Evangelist|Red Hat Brasil GNU Toolchain Engineer ___ linux-libre mailing list linux-libre@fsfla.org http://www.fsfla.org/cgi-bin/mailman/listinfo/linux-libre
