As I noted in the review on phabricator, it needs to be rearranged. It currently puts a bunch of code in the PCI bus that instead belongs in the PCI-PCI bridge (all the interrupt handling, MSI, etc. are properties of the bridge and should be handled in their rather than magic fields in the pci_dinfo of the bridge in the parent PCI bus). It is not a lot of code and probably wouldn't take long to finish. I had been waiting to let jmg@ finish it. https://reviews.freebsd.org/D3932 > Warner > > > On Tue, Jan 26, 2016 at 6:58 PM, Adrian Chadd <adrian.chadd@gmail.com> > wrote: > > > please grab the pciehp work that jmg has done and push it along to > > completion.
