Straightforward way to calculate it is to define the list of printing items and set needed buffer size for each one, then sum them up in initialization. But that might make code hard to maintain because we already have many small items and they are not in common format. Another approach independent of magic number or fixed-sized buffer is to extend the buffer with remalloc() when we are approaching the end. I hope the following patch might help. # This patch is relatively large (~400 lines) but most are simple replacement # of "sprintf(outp, ...)" with "append_to_output_buffer()".

Wysocki, Prarit Bhargava; +Cc: linux-pm, linux-kernel I updated the patch with a trival fix. Could you review it? - Naoya ---- From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Date: Fri, 19 Apr 2019 09:21:59 +0900 Subject: [PATCH v2] tools/power: turbostat: make output buffer extensible "turbostat --Dump" could be terminated by general protection fault on some latest hardwares which (for example) support 9 levels of C-states and show 18 "tADDED" lines. That bloats the total output and finally causes buffer overrun. So this patch sugguests to extend the output buffer when reaching the end. This patch also removes duplicated "pc10:" line to reduce buffer usage.
