3966 5704 d 5 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3940 5709 d 5 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3913 5712 d 8 h decky /trunk/ mips32: basic SMP support  
3910 5712 d 22 h decky /trunk/kernel/arch/mips32/ eliminate non-standard -D$(MACHINE)  
3908 5713 d 4 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3880 5717 d 2 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3790 5752 d 10 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 5753 d 0 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 5808 d 10 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3393 5874 d 2 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 5874 d 2 h jermar /trunk/kernel/arch/mips32/src/mm/ cstyle for mips32's tlb.c  
3236 5917 d 2 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 5917 d 9 h decky /trunk/kernel/arch/mips32/src/mm/ fixes  
3231 5917 d 9 h decky /trunk/kernel/arch/mips32/src/mm/ finer granularity (256 KiB)  
3230 5917 d 9 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup		  
3228 5917 d 19 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 6068 d 11 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6089 d 8 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 6090 d 8 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2720 6090 d 11 h decky /trunk/kernel/arch/mips32/src/mm/ prettyprint tlb command  
2170 6401 d 0 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 6474 d 2 h jermar /trunk/ (c) versus (C)  
1888 6599 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6664 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6671 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6671 d 8 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1735 6687 d 12 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6691 d 11 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 6692 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6699 d 15 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 6712 d 6 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 6715 d 2 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 6731 d 11 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 6750 d 9 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1044 6781 d 10 h jermar /kernel/trunk/ Page table locking.  
983 6783 d 7 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
958 6784 d 2 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 6811 d 23 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6815 d 6 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 6815 d 8 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().
