This is svn r13968, yes. > So the precompiled Cirrus rom code has a bug which I can't change, and > it looks like I'll have to upgrade my qemu to use anything other than > -vga cirrus (I'm at 1.2.0). Do we know if "-vga std" is the default in > qemu 1.3+ (and if std means the dispi device Gerd references above)? That's a densely packed paragraph, let's dissect it: - I don't know if CirrusLogic5430Dxe has a bug or not, but: it shouldn't be built into your OVMF.fd to begin with. Actually... Do you have an environment where qemu (auto-?)loads a pre-built CirrusLogic5430Dxe binary into the emulated video card as an option ROM, then OVMF downloads it and tries to post the card with it? - It's probably correct that for "-vga std" you'll need qemu 1.3+. Still if you try to use plain vga from OVMF with an earlier qemu version, OVMF shouldn't hang but "simply" refuse to initialize the card, and log "QemuVideo: BochsID mismatch [...]". - It seems to me that "-vga" has defaulted to "cirrus" since v0.11.0: that tag already contains commit 5824d651 "Syncing documentation vs. -help vs. qemu_options table", and said commit both calls cirrus default and is current (visible in master HEAD).
