- POWER7 runs little endian without VSX, but is only ISA 2.06 compliant.
* The assumption was that Any additions from ISA 3.0 would be emulated by the Linux kernel, that however did not work.
* We tried booting [Gentoo SFFS](https://libre-soc.org/SFFS/gentoo_bootstrap/) with a kernel compiled for POWER9, POWER8, and POWER7, all seem to fail with a kernel panic due to missing instructions.
+ * The POWER9 instructions were VSX from the v3.0 ISA
+ * likewise the POWER8 but also including some v2.08 instructions deprecated in v3.0
+ * POWER7 included some v2.07 instructions definitely deprecated in v3.0
* We also tried booting it with a kernel built for all three POWER versions mentioned earlier and also disabling VSX and/or AltiVec, still fails with a kernel panic due to missing instructions.
### We have tried patching QEMU's definition for POWER9 to exclude VSX and AltiVec
