Hi,

I've prepared update for NVidia drivers for Optimus users (bumblebee) [1]. The problem is, i586 last driver branch was 390.xx (390.87 atm), but for x86_64 there is 410.66 already. So I've tried to update package for x86_64 only.

Sorry, cknowledging my ignorance, I don't really know what the implications of this are. Does that mean that there will be no nvidia-bumblebee-32bit-410.66-1.1.x86_64? Or is it only no *x86 packages? If the former, how to run old 32bit applications?

i586 and x86_64/32bit are separate packages. i586 are for 32-bit systems: means 32-bit kernel module, 32-bit X module and 32-bit client libraries. Last versions are 390.xx for this. x86_64/32bit are for 32-bit apps on 64-bit system, so it contains just 32-bit client libraries (located in installer's directory "32"). Kernel module and X module are still 64-bit and installed from x86_64 package. So in i586 repository we have only 390 version while in x86_64 we have 410 for both x86_64 and x86_64/32bit packages. вівторок, 23 жовтня 2018 р. 14:39:43 EEST Stefan Dirsch написано:

There are no plans to drop support for 32bit applications by NVIDIA. I explicitely asked them about. But, yes they dropped support for pure 32bit systems. So no longer 32bit kernel module, nvidia X driver and glx extension.

Thanks. -- Kind regards, Mykola Krachkovsky -- Найкращі побажання, Микола Крачковський

You should still be able to create an i586 package for 32-bit systems running on a 64-bit kernel. It seems that Debian is now doing exactly that [1]. This way, you can still use the latest drivers on a 32-bit system provided your machine is running a 64-bit kernel. As you said, nVidia just stopped developing 32-bit kernel code, all the 32-bit userland code is still there and in development. Adrian

Hang on... how can you run a 64-bit kernel on a 32-bit machine?

You can't.

Sure, you can run a 32-bit _distro_ on a 64-bit machine, but not the reverse...

I didn't claim that. But it's not uncommon to use a 64-bit kernel with a 32-bit userland. It's not *that* common on x86 because 64-bit x86 is much more than just a doubled pointer width as compared to 32-bit x86 (more registers, instructions etc). But it's quite common on architectures like POWER or SPARC where a 32-bit userland can have measurable performance advantages over 64-bit. There is a largely unknown approach to achieve that on x86 called x32 for which there is a Debian port.

I'm not sure if 32-bit user space on 64-bit kernel is used by a lot of people. Most uses matched bitness of kernel & user space. And I don't know how to make that possible for NVidia drivers, as 32-bit userspace needs X server 32-bit module, but x86_64 installer has no such version, only 64-bit.

Next, I'm not sure it's good to have i586 package which would work only for mixed bit installation.

As you said, nVidia just stopped developing 32-bit kernel code, all the 32-bit userland code is still there and in development. Not only kernel, X server GLX module too and that's user space, right?

And if we are talking about 64-bit kernel+X server and 32-bit other stuff (e.g. games), we have nvidia-bumblebee-32bit for that already, and surely it has version 410.66. -- Kind regards, Mykola Krachkovsky -- Найкращі побажання, Микола Крачковський
