From ca62823b79443e3f498c6e6b9fea5f8bbe61033e Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 25 Sep 2019 15:12:07 +1000 Subject: spapr: Use less cryptic representation of which irq backends are supported MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SpaprIrq::ov5 stores the value for a particular byte in PAPR option vector 5 which indicates whether XICS, XIVE or both interrupt controllers are available. As usual for PAPR, the encoding is kind of overly complicated and confusing (though to be fair there are some backwards compat things it has to handle). But to make our internal code clearer, have SpaprIrq encode more directly which backends are available as two booleans, and derive the OV5 value from that at the point we need it.
