Hi
I tried out a few trivial sets of examples on gem5 as per your suggestion.
1. I used the CPP file handling to read the /sys/devices/system/cpu/possible
and print the content. This gave an output of 0-1 which is right since I was
using a 2 core gem5 configuration.
2. I used the system function to "cat" the contents of the same file in this
program. It failed. Gave an abort and gave the following error:
warn: ignoring syscall mprotect(...)
warn: ignoring syscall mprotect(...)
warn: ignoring syscall mprotect(...)
warn: ignoring syscall rt_sigaction(...)
warn: ignoring syscall rt_sigaction(...)
warn: ignoring syscall rt_sigprocmask(...)
(further warnings will be suppressed)
warn: PowerState: Already in the requested power state, request ignored
warn: User mode does not have SPSR
warn: User mode does not have SPSR
panic: panic condition !handled occurred: Page table fault when accessing
virtual address 0x3fffbb1e80
Memory Usage: 8553040 KBytes
Program aborted at tick 1061222000
I suppose SE is not supporting such calls ?
