Due to enter_idle_powerx fabricating a MSR from scratch, it is necessary for it to care about the endianness, so we don't accidentally switch endian the first time we idle a thread. Took about five seconds to spot after seeing an unmangled backtrace. The hard bit was needing to temporarily set up a mutex to sort out the logjam that happens when every thread simultaneously wakes up in the wrong endian due to the panic IPI and panics, leaving what I can best describe as "alphabet soup" on the console. Luckily, I already had a patch sitting around to do that. This brings POWER8 up to equivilence with POWER9 on PPC64LE. Sponsored by: Tag1 Consulting, Inc. |
