asm/types.h changed to asm-generic/types.h in linux kernel

sncak · 02-17-2021, 04:03 AM

I am trying to compile a wifi driver for linux-kernel-5.10.13 on my armv8 board while trying to compile I got an error that

Code:

asm/types.h not found

and I came to know that

Quote:

asm directory was changed to asm-generic

but the issue is there is a lot of code that is still including asm/types.h instead of asm-generic/types.h,
I am new to Linux and I wanted to know is there any way that I can link renamed asm directory to the asm-generic directory

there is a command ln to create links, you will need a symbolic link, but I'm not really sure if that was the perfect solution (although you may try it if you wish).

would be nice to know what was not working exactly?
Also would be nice to know what did you try to compile exactly?

I've cloned the repository from here and tried to compile the Wifi module following steps from here after following the steps and when trying to compile then I get the error

asm/types.h not found

and I am trying to compile for the armv8 board.

and did you create a symbolic link? (how?)

sncak · 02-17-2021, 08:29 AM

I tried creating a symbolic link but failed

ln -s asm asm-generic

what was the reason? what's happened? You may need to use root to create that link.

If both directories already exist then you cannot create a symlink in same location. You may need to symlink individual files or simply copy them over to new location, it does not hurt to have same files in two directories.

additionally I'm not really sure if this source was really compatible with this kernel. Probably need to be uplifted.
but as I see this driver is included in the kernel, so there is no need to do that at all.

yes, it is true, actually, I am trying to change the wifi driver setting to a concurrent mode so I can turn on Access point mode and station mode at a time. so happened to recompile the module.

is there any other way so I can extract, make config changes and recompile the module.

since [if] it was built into the kernel you need to rebuild it (or at least this kernel module). I mean forget this git repo and download the kernel source instead and modify/reconfigure it.
