[libvirt] [PATCH] RFC: bhyve: implement PCI address allocation

Hi, This is the first attempt to implement PCI address allocation for the bhyve driver. This patch is by no means a complete version and the idea of this is to understand if I'm moving in a right direction. This code is based on the one from QEMU driver. Even though bhyve currently has no support for PCI bridges, it should be possible to add that support without major rewrites when this feature will be available in bhyve. So, currently we have the following. For a domain like that: https://gist.github.com/novel/10569989#file-domainin-xml The processed domain looks this way: https://gist.github.com/novel/10569989#file-domainout-xml and the command is: https://gist.github.com/novel/10569989#file-cmd Please let me know if it's uncomfortable to follow gist links; I didn't put domain xml inline as it's pretty lengthy. Open questions are: * What's the best way to deal with the 0:0,hostbridge device, should it be explicitly added to the domain definition? * How to handle lpc device, that's required for console. From bhyve point of view it looks like this: -s 31,lpc -l com1,ttydev That is, LPC PCI-ISA bridge on PCI slot and com1 port on that bridge. Things that need to be fixed in that patch, but are obvious: * Fix 'make check' which fails for obvious reasons of new addresses in domain xml * As we support more than one disk device, respect boot order Roman Bogorodskiy (1): bhyve: implement PCI address allocation po/POTFILES.in | 1 + src/Makefile.am | 4 + src/bhyve/bhyve_command.c | 128 +++++++++++----------- src/bhyve/bhyve_device.c | 272 ++++++++++++++++++++++++++++++++++++++++++++++ src/bhyve/bhyve_device.h | 41 +++++++ src/bhyve/bhyve_domain.c | 75 +++++++++++++ src/bhyve/bhyve_domain.h | 41 +++++++ src/bhyve/bhyve_driver.c | 9 +- 8 files changed, 503 insertions(+), 68 deletions(-) create mode 100644 src/bhyve/bhyve_device.c create mode 100644 src/bhyve/bhyve_device.h create mode 100644 src/bhyve/bhyve_domain.c create mode 100644 src/bhyve/bhyve_domain.h -- 1.9.0
