[PATCH qemu] spapr: tune rtas-size

2021-06-22 Thread Alexey Kardashevskiy

QEMU reserves space for RTAS via /rtas/rtas-size which tells the client how much space the RTAS requires to work which includes the RTAS binary blob implementing RTAS runtime. Because pseries supports FWNMI which requires plenty of space, QEMU reserves more than 2KB which is enough for the RTAS
