2128 6333 d 0 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.		  
2123 6340 d 3 h decky /trunk/kernel/generic/src/mm/ add forgotten unsigned  
2122 6340 d 3 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2121 6340 d 4 h decky /trunk/kernel/generic/src/mm/ remove anonymous structure, add static qualifier  
2089 6348 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6354 d 6 h decky /trunk/kernel/ typedef elimination  
2071 6358 d 23 h jermar /trunk/ (c) versus (C)  
2059 6382 d 8 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2048 6391 d 0 h jermar /trunk/ Formatting and indentation changes.  
2035 6394 d 4 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
1981 6419 d 7 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1894 6478 d 20 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel		  
1854 6500 d 8 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1833 6527 d 18 h decky /trunk/kernel/ more sophisticated initial stack handling  
1790 6547 d 2 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1787 6549 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6556 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6564 d 9 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1766 6564 d 9 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6567 d 3 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1757 6570 d 7 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6574 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6577 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1700 6577 d 8 h palkovsky /kernel/trunk/generic/src/mm/ Fixed frame allocator to allocate correct number of frames for configuration.
(It couldn't fail before, but in some circumstances it could allocate more
then needed).		  
1599 6584 d 10 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1568 6586 d 3 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1269 6620 d 0 h decky /kernel/trunk/ PHT Refill handler  
1248 6624 d 2 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1236 6625 d 7 h jermar /kernel/trunk/generic/ Add frame_reference_add().  
1224 6628 d 5 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1221 6628 d 20 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6635 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1093 6662 d 21 h palkovsky /kernel/trunk/generic/src/mm/ Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced).		  
1063 6665 d 19 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1037 6666 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
946 6669 d 21 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
852 6692 d 4 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
824 6701 d 10 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6701 d 20 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
820 6701 d 21 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
