What I finally figured out was that "-march=native is *EXTREMELY* |
| 10 |
conservative". As a matter, I started a new thread on exactly that |
| 11 |
topic<G>. To summarize... "-march=native" had disabled mmx, sse, sse2, |
| 12 |
sse3 (aka pni), and ssse3, all of which are available on the cpu. After |
| 13 |
explicitly adding those flags to CFLAGS, emerging system+world, and |
| 14 |
rebuilding the kernel, it runs 1080p just fine, thank you. |
