Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/pc-bios/spapr-rtas/spapr-rtas.S?h=spice_video_codecs 2019-10-04T00:25:23+00:00 2019-10-04T00:25:23+00:00 Alexey Kardashevskiy 2019-07-16T05:27:43+00:00 urn:sha1:744a928ccee92482385f58e835108aa6ebd54ecb SLOF implements one itself so let's remove it from QEMU. It is one less image and simpler setup as the RTAS blob never stays in its initial place anyway as the guest OS always decides where to put it.

On logical partitions under a hypervisor, many of the RTAS functions require hypervisor privilege. For simplicity, therefore, hypervisor systems typically implement the in-partition RTAS as just a tiny wrapper around a hypercall which actually implements the various RTAS functions. This patch implements such a hypercall based RTAS for our emulated pSeries machine. A tiny in-partition "firmware" calls a new hypercall, which looks up available RTAS services in a table.
