ACTIVE - Kernel with migrating threads as IPC https://metanimi.dy.fi/cgit/kmi/atom?h=master 2024-07-05T16:38:11Z 2024-07-05T16:38:11Z Kimplul kimi.h.kuparinen@gmail.com 2024-07-05T16:38:11Z urn:sha1:e09edb5d54e39bd9509a1dc450df5ab320759f97 + Took some fairly significant changes, for one the kernel is no longer relocated at the start of a boot, instead it sits wherever the user decides the kernel should sit. Similarly, the initial kernel stack and page table are stored within the binary, slightly bloating the size but making it much safer to boot since there's really no chance of us overwriting the fdt or initrd in memory. 2023-05-29T18:31:09Z Kimplul kimi.h.kuparinen@gmail.com 2023-05-29T18:31:09Z urn:sha1:3ace1ddd76b9c04f3ed23883de6279b4485612e8 + Not bootable quite yet. Among other things, I couldn't get the current starfive u-boot fork to boot, so try adding support for booting with precompiled u-boot via the `go` command. Initial testing with qemu shows that this should be possible, and if it works, might be useful in the (far) future with other slightly janky SBCs. Also, NS16550 is 8250-based, and I'm really only using the base 8250, so rename and add visionfive 2 uart to list of compatibles. Visionfive 2 is still completely untested. 2023-05-11T21:36:18Z Kimplul kimi.h.kuparinen@gmail.com 2023-05-11T21:36:18Z urn:sha1:4cde8bceb1ff14896884c224850f6c7611551175 + RELEASE=1 doesn't work for some reason, though 2023-05-11T19:55:31Z Kimplul kimi.h.kuparinen@gmail.com 2023-05-11T19:55:31Z urn:sha1:27ffa747f36aee9c1d5bbc61395a078238366070 + Both kind of go hand in hand, made sense to do both at the same time. Some parts feel slightly hacky, the loader works by placing everything on the stack and avoiding global values. Still, seems to work? 2023-05-01T19:02:49Z Kimplul kimi.h.kuparinen@gmail.com 2023-05-01T19:02:49Z urn:sha1:05d4244f68e35c1bef6488292bf9730df3636fd9 2022-10-21T18:34:18Z Kimplul kimi.h.kuparinen@gmail.com 2022-10-21T18:34:18Z urn:sha1:dd7c04a39bd88da8e381bb88078c41b049a6665c 2022-06-12T10:58:42Z Kimplul kimi.h.kuparinen@gmail.com 2022-06-12T10:58:42Z urn:sha1:6c529c5c6c2d016d77b143171c5e27fbec0d2bfd 2022-05-28T22:07:48Z Kimplul kimi.h.kuparinen@gmail.com 2022-05-28T22:07:48Z urn:sha1:0f4a751e60a6c8ac40592ff44c74f1c9e4846d9a 2022-01-07T12:05:06Z Kimplul kimi.h.kuparinen@gmail.com 2022-01-06T21:39:12Z urn:sha1:9cc125fb3cfdc2c8ae7153b5ae0fe705980835fb + Release mode is sort of broken, as lto doesn't work with linker relaxation and turning the relaxation off causes issues with the jump from init to kernel (as I've currently implemented it, could probably be fixed with a manual jump from assembly, I'll add it to my TODO list)
