3880 5649 d 11 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3790 5684 d 19 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5685 d 8 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3586 5740 d 19 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3393 5806 d 10 h jermar /trunk/kernel/arch/mips32/src/mm/ Write protection fault should not panic the mips32 kernel if it happens during
copy_to_uspace().		  
3392 5806 d 11 h jermar /trunk/kernel/arch/mips32/src/mm/ cstyle for mips32's tlb.c  
3236 5849 d 11 h decky /trunk/kernel/arch/mips32/src/mm/ limit physical memory to 512 MB (more cannot be used right now, see ticket #29)
fix physical memory detection in gxemul (which doesn't honor uncached flag in TLB)		  
3232 5849 d 18 h decky /trunk/kernel/arch/mips32/src/mm/ fixes  
3231 5849 d 18 h decky /trunk/kernel/arch/mips32/src/mm/ finer granularity (256 KiB)  
3230 5849 d 18 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup		  
3228 5850 d 4 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support		  
2745 6000 d 20 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6021 d 17 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2722 6022 d 17 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2720 6022 d 20 h decky /trunk/kernel/arch/mips32/src/mm/ prettyprint tlb command  
2170 6333 d 9 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2071 6406 d 11 h jermar /trunk/ (c) versus (C)  
1888 6531 d 14 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6596 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6603 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6603 d 16 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1735 6619 d 20 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6623 d 20 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6624 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6632 d 0 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1411 6644 d 14 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1396 6647 d 11 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1288 6663 d 19 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1196 6682 d 18 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1044 6713 d 18 h jermar /kernel/trunk/ Page table locking.  
983 6715 d 16 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
958 6716 d 11 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
836 6744 d 8 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6747 d 15 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).		  
830 6747 d 17 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
815 6749 d 18 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6749 d 19 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
793 6751 d 16 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
765 6755 d 10 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6755 d 15 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.
