Gag, I blame a bum vpn connection and botch vim recovery ;) Here's what I meant to list: This is the first non-RFC posting, so if you wish to review and provide comments, now is the time to do so. What's new in v6: * The fw_cfg entry for BDSM reservation has changed per Gerd's feedback. This will require a new SeaBIOS to make the matching change (incompatible with previous postings). * Added a docs entry for IGD assignment covering both the usage of UPT vs legacy mode as well as the ABI using fw_cfg. * Fix some uninitialized pointer issues if we bail out of legacy mode setup. * Leak igd_opregion if we happen to be hot-unplugged. I don't see a better option given the fw_cfg dependency, we really don't want to support unplug of IGD at all. I believe we're no longer blocked by SeaBIOS being willing to consume the new fw_cfg entries, so barring feedback otherwise, my plan will be to send a pull request including these changes (after an appropriate review period), ask Kevin to apply the matching SeaBIOS change, then see if Gerd will help me pull that support into the default QEMU SeaBIOS image. There is a plethora of comments and documentation in this series, so I will forego further description of what this enables. Jump to the last patch to read about it or hit patch 6 for the very well documented (IMO) meat of IGD support. Thanks!
