make gim compatible with kernel >= 5.0 #24

Open flumm opened 5 years ago

flumm commented 5 years ago

kernel 5.0 removed some deprecated timespec/timeval functions so conditionally convert everything to timespec64

Hi flumm

You’d better make your change compatible with pre-5.0 kernel: [cid:image001.jpg@01D52B73.5E340AC0]

Look your change would break old kernel , e.g. 4.13

Maybe you can use MACROS to differentiate whether use timespec or TIMESPECTYPE

Maybe you can use MACROS to differentiate whether use timespec or TIMESPECTYPE

but i am doing exactly this?

in gim_adapter.h i define TIMESPECTYPE as timespec for kernels < 5 and as timespec64 for kernels >= 5

i did this to avoid dozens of `#if LINUX_VERSION_CODE <... ..

else

...

endif`

blocks.

also i can build and load it here on an debian stretch with kernel 4.9.0 without problems

Oh no problem

Pretty please @ljymonk ?

Does gim support 5.x kernel?

flumm commented 4 years ago

Does gim support 5.x kernel?

well i'm using it with this pull request since quite some time up to kernel 5.4 (cannot say for newer kernels), so i'd say it works, but since nobody from amd commented yet, i do not know if its 'supported'

mac-linux-free commented 3 years ago

Could you please make GIM compatible with newer Kernels? 5.9+
