Re: [tboot-devel] txt-test.ko build failure

[Wang, S. <sha...@in...>]

I think that should be your txt public config space is reserved by kernel. see variable iomem_resource.
I haven't tried it on the kernel but on xen unstable. I think there must be somewhere to reserve it, perhaps e820 parsing in the kernel since the range is reserved in e820 table.
Can you try to remove the range out of iomem_resource?
