fef	f8a85a1541	happy new year 2022 uwu ... May it be slightly less exhausting than 2021.	2022-01-01 03:49:33 +01:00
fef	7285c2e076	mm: refactor entire mm subsystem, part 1 ... Another one of those larger endeavours that take multiple commits. This first one introduces the basic vm_page data structure, as well as the x86 bootstrap code for initializing it.	2021-11-17 05:13:23 +01:00
fef	5a5135f416	update license terms ... As of now, everything except the code imported from FreeBSD is proprietary. Of course, it won't be like this for long, only until we have decided which license we like to use. The rationale is that releasing everything under a copyleft license later is always easier than doing so immediately and then changing it afterwards. Naturally, any changes made before this commit are still subject to the terms of the CNPL.	2021-11-15 19:23:22 +01:00
fef	f0706b802b	boot: ignore unaddressable RAM areas on i386 ... We don't support PAE or any other fancy hack to get past the 4 GB limit on 32-bit, so we have to clip areas that would fall outside that range	2021-10-21 23:21:56 +02:00
fef	3fee893f21	x86: begin preparations for amd64 support ... This is a huge commit, but it mainly just moves some files around and doesn't change their contents much. A lot of stuff works the same on amd64 as it does on i386, so i'm moving the parts that are specific to the latter into separate subdirectories while the rest can be shared with the amd64 codebase.	2021-10-21 05:27:42 +02:00
fef	c3847487be	config: refactor kernel address mapping names	2021-10-15 19:52:22 +02:00
fef	65899b35f1	x86: minor page management refactor ... Even Uranium-223 ages better than my code	2021-10-13 20:55:35 +02:00
fef	d475429639	kprintf: implement "full" format sequence support ... So this was painful. kprintf() supports most of the format specifiers from BSD now, except for the $ sequence. It has gotten a general overhaul and is significantly more sophisticated, bloated and slower now. There is also some minor stuff i forgot about, like the 't' length modifier, but that isn't so important right now and will be fixed later(TM).	2021-10-03 04:31:28 +02:00
fef	613c28a965	x86: add basic interrupt support ... This commit also fixes the fun little size bug in segment.S where i subtracted the end from the start address of the GDT instead of the other way round which resulted in a gigantic overflow :)	2021-10-02 00:08:54 +02:00
fef	3d6258a06e	mm: implement runtime page mapping	2021-09-23 20:51:12 +02:00
fef	17320f2571	boot: enable paging in boot sequence	2021-09-22 03:50:55 +02:00
fef	d436d9b203	mm: add page frame allocator	2021-09-21 18:25:54 +02:00
fef	2a0ed8121a	util: refactor misc utility stuff	2021-09-21 17:34:27 +02:00
fef	25e00354ec	x86/boot: move multiboot code to arch	2021-09-20 17:59:15 +02:00
