NetBSD 8.0 release process underway

June 06, 2017 posted by Soren Jacobsen

If you've been reading source-changes@, you likely noticed the recent creation of the netbsd-8 branch. If you haven't been reading source-changes@, here's some news: the netbsd-8 branch has been created, signaling the beginning of the release process for NetBSD 8.0.

We don't have a strict timeline for the 8.0 release, but things are looking pretty good at the moment, and we expect this release to happen in a shorter amount of time than the last couple major releases did.

At this point, we would love for folks to test out netbsd-8 and let us know how it goes. A couple of major improvements since 7.0 are the addition of USB 3 support and an overhaul of the audio subsystem, including an in-kernel mixer. Feedback about these areas is particularly desired.

Thanks in advance for helping make NetBSD 8.0 a stellar release!




Some highlights: - DTrace! ASan! UBSan! - Most platforms provide fenv.h now! - Toolchain updates! clang 4.0 and GCC 5.4 - USB 3 - The sdmmc stack now supports UHS-I and HS200 transfer modes. The sdhc and the amlogic sd controller (ODROID C1) drivers take advantage of this now. Security: - W\^X memory mappings by default. - ASLR default (for PIE binaries) amd64: - kernel no longer has WX pages - Disallowing mapping of zero page - Kernel is mapped using large 2MB pages - Nouveau DRM driver - Native UEFI bootloader ARM: - Great support for some nvidia tegra boards (go jmcneill go!) - Probably more but I don't follow ARM closely! MIPS: - Now uses generic pmap shared with powerpc (possibly will be shared with ARM too depending on progress). - Much more stable! (lots of little fixes) - pmax (oldest MIPS) switched to common MIPS bus_dma VAX, pmax: - TC USB! you can now use USB via turbochannel.

Will this version have a threaded IP stack? Either way I love NetBSD and I'm glad to see it continue onward.

Pretty excited about dtrace and even more so to see the pmax getting some love and hopefully I can get my tc usb up and running on 24mb ram. Nice one! Looking forward to it all.

It would be nice if wvstreams, wvdial, wvconf were added to the base installation set.

Not to be a killjoy, but an in-kernel audio mixer doesn't sound like a great idea to me. Other than that, keep up the good work!
