| 1 | Background: |
| 2 | trace-cmd, Function Trace and KernelShark look like very useful tools |
| 3 | for embedded Gentoo. I did manage to find an existing overlay of |
| 4 | unknown quality. [1] |
| 5 | |
| 6 | Has anyone on this list used or have any comments on these tools or |
| 7 | equivalents? [2] |
| 8 | |
| 9 | Has anyone compared KernelShark to the output of a (physical) |
| 10 | jtag setup? |
| 11 | |
| 12 | |
| 13 | Curiously, |
