While it is reasonable to expect this much, we seldom get anywhere near that.
The usual fare is, unfortunately, just an android kernel source tarball that has been modified so that it works with the hardware, with no history of changes nor documentation of the hardware.
The situation with GPUs, specifically, is really bad.
Intel, AMD and now Imagination Technologies are about the only ones, that I am aware of, who seem to care about open drivers.
- wereallterrrist 4y agoDon't AMD GPUs still have firmware blobs, they just happen to submit them to upstream linux-firmware?
- Heston 4y agoYeah, the open drivers don't matter a whole lot. It just loads the closed source proprietary blob into the gpu. It's a step in the right direction but can be very misleading.
- pabs3 4y agoThe worst part is when those blobs are signed, then you can't reverse engineer them and replace them with open firmware.
- snvzz 4y agoThis is one of many ways by which NVIDIA actively sabotages the open source driver effort. They were catching up at some point, and NVIDIA started doing that.
- pabs3 4y agoThe good news is that with the new open Linux kernel drivers from NVIDIA, Nouveau folks will be able to use the same signed proprietary firmware as the proprietary userspace component of the NVIDIA drivers. So that should unblock development of the open userspace component of the libre Nouveau drivers too.
- mananaysiempre 4y agoAMD’s linux-firmware blobs also exclude OpenCL support IIRC.
- dogben 4y agoThey do support OpenCL. You only need their closed source user space library libamdocl*.so and libamd_comgr.so to use it.
- xen2xen1 4y agoThey do, IIRC, but, interestingly, Nvidia doesn't only because they put a RISC V processor on board that keeps it's own blob a few generations back (20xx?). I'm not sure that's actually more open, but I guess if you can run it with all open source drivers and no proprietary blob, that's good?
