…nux.c In core_throttles_set[n][m], n has size 32 only. On my PC, I have 44 cores and physical_package_id can have max value of 88. On line 140 we see: if (core_throttles_set[physical_package_id][core_id] != 0) This causes a segmentation fault as we access data from invalid address outside the range of buffer. The size is changed to 256 to accomodate high core count. Signed-off-by: Faran Abdullah faran.abdullah@ebryx.com Signed-off-by: Faran Abdullah <faran.abdullah@ebryx.com>

…nux.c
The issue is in ne_cpu_linux.c
In core_throttles_set[n][m], n has size 32 only.
On my PC, I have 44 cores and physical_package_id can have max value of 88.
On line 140 we see:
if (core_throttles_set[physical_package_id][core_id] != 0)
This accesses array at index 88, that has size of only 32.
This causes a segmentation fault.
Because we access data from invalid address outside the range of buffer.
Fix: The size is changed to 256 to accomodate high core count.
