element sizes in input_event struct on riscv32

[Antonios Salios]

Hi all.

I'm having trouble getting evdev to run in a simulated Buildroot
environment on riscv32. Evtest (and the x11 driver) seems to be
receiving garbage data from input devices.

Analyzing the input_event struct shows that the kernel uses 32-bit (aka
__kernel_ulong_t) values for __sec & __usec.
Evtest on the other hand interprets these variables as 64-bit time_t
values in a timeval struct, resulting in a mismatch between the kernel
and userspace.

What would be the correct size for these values on a 32-bit
architecture that uses 64-bit time_t values?


Kind regards
