4490 5495 d 18 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4137 5573 d 17 h svoboda /trunk/kernel/ Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.  
4132 5574 d 16 h svoboda /trunk/ Make kernel symbol information optional.  
4108 5578 d 20 h decky /trunk/kernel/arch/mips32/src/mm/ remove unmaintained Simics machine (might return later)
whitespace changes		  
3973 5592 d 2 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3967 5593 d 20 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5593 d 20 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3940 5598 d 20 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3913 5602 d 0 h decky /trunk/ mips32: basic SMP support  
3910 5602 d 13 h decky /trunk/kernel/arch/mips32/ eliminate non-standard -D$(MACHINE)  
3908 5602 d 19 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3880 5606 d 18 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3790 5642 d 2 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 5642 d 15 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 5698 d 1 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3393 5763 d 17 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 5763 d 17 h jermar /trunk/kernel/arch/mips32/src/mm/ cstyle for mips32's tlb.c  
3236 5806 d 17 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 5807 d 0 h decky /trunk/kernel/arch/mips32/src/mm/ fixes  
3231 5807 d 0 h decky /trunk/kernel/arch/mips32/src/mm/ finer granularity (256 KiB)  
3230 5807 d 0 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup		  
3228 5807 d 10 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 5958 d 2 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5978 d 23 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 5979 d 23 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2720 5980 d 3 h decky /trunk/kernel/arch/mips32/src/mm/ prettyprint tlb command  
2170 6290 d 15 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 6363 d 17 h jermar /trunk/ (c) versus (C)  
1888 6488 d 21 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6553 d 19 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6560 d 20 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6560 d 23 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1735 6577 d 3 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6581 d 2 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 6581 d 23 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6589 d 6 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 6601 d 21 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 6604 d 17 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 6621 d 2 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 6640 d 0 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
