That's just a *warning* and doesn't stop the build. The reason that we have that warning is because on most architectures, the entire kernel stack has to fit into 2 contiguous 4k pages. And a perfectly legal stack can be something like TCP delivering an NFS packet which then goes to the NFS code, which then hands it off to the VFS layer, which checks the page cache, which hands it off to XFS, which schedules I/O to the filesystem, which gets handed to the block subsystem, which realizes that the target partition is an LVM partition, and LVM realizes that the "physical volume" is actually a dm-crypt, and then dm-crypt does some cryptography and calls the block subsystem to write to the physical disk. Feel free to check the code path yourself... :) And all of that has to fit in 8K of stack. That's why we warn when things have a large stack frame entry. Anyhow, "possible missing firmware" isn't even at compile time - it's during the build of the initramfs at *install* time. And the most likely cause of that is that missing external firmware that's not GPL - it's all confined to 2 graphics drivers - amdgpu and i915, so not at all related to a warning against cpufreq... --==_Exmh_1616563564_11646P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBYFrNawdmEQWDXROgAQLkMA//RxElCKkNiVdK2be/GUBCwykO1Wrp8F7Z N3cNfbMH+qy/TotyfS7Cd3scSVz23chJZ3Xyjo/y3zGqNZZF4d6QPZp9/BIZ+ijr gaN9DQCMAsHPZLhe4KgZ/4DcKDBO+C3JOhvEu8Eg1A18vvdU4M6NZQLr+/E+/y+N qoFHzzPm+KyeoQlq6aZMTLS/HYrQlvDwXyp6AorTVoJsTGK5Ja8HFnwLWmLQMKsU b3X5AZwLYsc1G6bLB4PUOU+ET+xyqgl+y3p6Rz6536iOQscypPexwAUBm7ICYu9W L/7Y7GyhY77OFdmhwAODdWnfApIlMktdXhrGqDMbZiJbU2kTci1JOj8829ts4dmW w3QqztYF2qCLnB3V4xjeMmA3i0gPQ0SttuiwT1euqNSSkh/3L6fJmDgAXpdPuwwp c76cpDCClJV/ZXzDPNl87URr3kphNxV+9/XTZ0V4MXZ3UqYWGX622ud06TcFJqdP dpnjflYIjeNPlpg/iyNROUi49sMNBm1WAwpbLkceTRS04Cz4UeyfMXEBN0jsnXYt 1D807w5DmpDEKunc940FJnQaHDDGZJalLQf3ZVTBoQ/yT4gTQXu/G4/tn/EZl6E/ GdgNJcWBIDUtx2aJkKXrJpAH71TQLPIOoDa6yNrW1piNWEIlgusYskzt3etNaVuH JTXkMxJ2iWY= =YTXq -----END PGP SIGNATURE----- --==_Exmh_1616563564_11646P-- --===============2691703767303455434== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============2691703767303455434==--
