which is -3 in netbsd, which we have mapped linux ERESTARTSYS to. this has a problem because linux code often returns errors and pointers in the same value, and pointer values between -4095 and -1 are considered as error returns, but -3 ends up as 3 and thus is not considered an error, and mayhem ensues. with this in place my kabylake system seems actually stable, i have not triggered any of my prior issues in almost 4 weeks now. Taylor asked me to write up a description and then wrote most of the text below for me :-) In Linux code, we always work with ERESTARTSYS so the code meaning start over is a positive NetBSD errno safe for PTR_ERR/ERR_PTR. To achieve this: 1. adapt all cv_waits that return to Linux so they map ERESTART to ERESTARTSYS, and 2. adapt all returns to userland so they convert ERESTARTSYS to ERESTART. Leave EINTR and all other error codes alone. |

NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ freenode.
