Running Linux 4 and /usr/src/linux pointing to Linux 4 sources

configure: Linux detected as host for PCI host device mapping
configure: error: Linux kernel 2.4, 2.6 or 3.x is required for PCI host device mapping



Reproducible: Always

Don't enable pcidev support by default

Comment 4 Kobboi 2015-08-25 09:36:47 UTC

Justification for patch is in the upstream bug report:

"The PCI host device mapping is a very experimental feature and unfortunately not maintained yet. That's why it currently better to remove the --enable-pcidev option from the configuration. This feature worked with Linux kernel 2.4 and 2.6, but I don't know whether or not it is possible to compile the kernel module with version 3.x. There is another related bug report present (#1189), but I don't know the status and there is no Linux kernel expert active here."

Comment 5 selurvedu 2015-09-23 14:35:40 UTC

I confirm this on Linux 4.x.

allow linux 4

This is a totally stupid patch but should fix the configure abort. The clean solution would be an additional useflag that enables the build of the kernel module.

Comment 7 Jonas Jelten 2015-10-14 09:43:57 UTC

(the additional useflag is implemented in the other patch by Kobboi)
