padlock: Restore padlock_rng to the amd64 buildRevert 88a53301e19 and d1ca01059d5 . They removed padlock_rng from theamd64 build under the mistaken belief that this device was available on32-bit processors only.

Mon, 05 Jan 2026 04:36:55 +0100

asmc(4): pull 32-bit support for the driverThe asmc(4) driver should work for 32-bit Intel-based Macs, in theory, ifthe model details were added to the detection list. That being said,32-bit Intel Macs were only released and available to the general publicfor 8 months [1], so the value in maintaining i386 support in the driver isreduced due to limited hardware access.Remove 32-bit support for the driver officially to make it clear its use isnot supported.This should fix building `NOTES.i386` by proxy as well.Relnotes: yesMFC after: 2 weeksFixes: f224591746b ("Add ASMC_DEBUG make option")Fixes: 8342d9f7b5f ("asmc(4): Stop building it on i386, as...")Differential Revision: https://reviews.freebsd.org/D55544 List of files: /freebsd/sys/x86/conf/NOTES

6aae3517ed2500fb963ba0a4264b4756088dd0f4 - Retire synchronous PPP kernel driver sppp(4).

Thu, 21 Oct 2021 06:08:13 +0200

Retire synchronous PPP kernel driver sppp(4).The last two drivers that required sppp are cp(4) and ce(4).These devices are still produced and can be purchasedat Cronyx .Since Roman Kurakin has quit them, they nolonger support FreeBSD officially. Later they have droppedsupport for Linux drivers to. As of mid-2020 they don't evenhave a developer to maintain their Windows driver. However,their support verbally told me that they could provide aid toa FreeBSD developer with documentaion in case if there appearsa new customer for their devices.These drivers have a feature to not use sppp(4) and create aninterface, but instead expose the device as netgraph(4) node.Then, you can attach ng_ppp(4) with help of ports/net/mpd5 ontop of the node and get your synchronous PPP. Alternativelyyou can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.Actually, last time I used cp(4) back in 2004, using netgraph(4)instead of sppp(4) was already the right way to do.Thus, remove the sppp(4) related part of the drivers and enableby default the negraph(4) part. Further maintenance of thesedrivers in the tree shouldn't be a big deal.While doing that, remove some cruft and enable cp(4) compilationon amd64. The ce(4) for some unknown reason marks its internalDDK functions with __attribute__ fastcall, which most likely issafe to remove, but without hardware I'm not going to do that, soce(4) remains i386-only.Reviewed by: emaste, imp, donnerDifferential Revision: https://reviews.freebsd.org/D32590See also: https://reviews.freebsd.org/D23928 List of files: /freebsd/sys/x86/conf/NOTES

Wed, 23 Sep 2020 21:18:53 +0200

Use envvar rather than nonstandard hint. linesThe NOTES files have a bunch of hint lines that are removed whengenerating LINT. However, we can achieve the same effect by prependingeach of the lines with 'envvar' so the NOTES files become standardconfig(8) files. No functional changes as the sed script to generatethe LINT files filters these either way.Suggested by: kevans List of files: /freebsd/sys/x86/conf/NOTES

99e1c5ab38aa0768d29406ea9da496d51ba4d2af - Move sc out of the global file

Tue, 13 Aug 2019 00:58:44 +0200

Move sc out of the global filex86 needs sc, as does sparc64. powerpc doesn't use it by default, but some oldpowermac notebooks do not work with vt yet for reasons unknonw. Even so, I'veremoved it from powerpc LINT. It's not in daily use there, and the intent is to100% switch to vt now that it works for that platform to limit support burden.All the other architectures omit some or all of the screen savers from theirlint config. Move them to the x86 NOTES files and remove the exclusions. Thisreduces slightly the number of savers sparc64 compiles, but since they are inGENERIC, the overage is adequate and if someone reaelly wants to sort them outin sparc64 they can sweat the details and the testing.Reviewed by: jhb (earlier version), manu (earlier version), jhibbitsDifferential Revision: https://reviews.freebsd.org/D21233 List of files: /freebsd/sys/x86/conf/NOTES
