The Big Kernel Lock (BKL) is going to be removed.
This is going to be, perhaps, one of the biggest architectural changes in the QNX 6.4 codebase. And the direction is the same as QNX 8 took.
Stay tuned.
Now it feels like a Proper System.
Dear Spacemit! If you are reading this post, and if you would like to see r/QRV_OS running on your board -- please respond. The K3 board has a chance to become the first ultra-modern RISC-V system on which the QNX-derived OS is running ;)
Currently QRV runs on Unmatched (and under QEMU of course). Kernel and user-space Unix-like environment is up and running.
QRVFS v2 is now the Proper Filesystem™ too ;-) . Maximum file size now is 511 G.
Currently, QRV FS (v1) has one very serious limitation: the maximum file size is 2 megabytes.
Version 2 of the filesystem will remedy that.
First binary program is executed from the QRV filesystem on disk.
Preparation for the filesystem-on-disk on full swing. This milestone is huge: MSI-X seems to be working. Some polishing is needed, though.
Stay tuned.
It is readonly; it understands GPT partitions, and it's ready to be tested on real hardware (Unmatched).
That will be the v0.24 of our OS.
