2106 6358 d 10 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2089 6364 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6365 d 6 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6375 d 3 h jermar /trunk/ (c) versus (C)  
1958 6457 d 10 h decky /trunk/kernel/arch/amd64/ amd64: adopt new IRQ interface  
1888 6500 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1833 6543 d 22 h decky /trunk/kernel/ more sophisticated initial stack handling  
1787 6565 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6572 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1735 6588 d 12 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6592 d 12 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 6593 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6600 d 16 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 6613 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.
 
1382 6617 d 2 h decky /kernel/trunk/ make hardware memory mapping more generic  
1288 6632 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.
 
1212 6645 d 5 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1196 6651 d 10 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1064 6681 d 23 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6681 d 23 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1051 6682 d 7 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
825 6717 d 6 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
814 6718 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
799 6720 d 2 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
793 6720 d 8 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.
 
756 6725 d 23 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
 
755 6726 d 22 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.
 
694 6749 d 5 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
691 6749 d 6 h jermar /kernel/trunk/arch/ Cleanup.  
690 6749 d 7 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
687 6749 d 7 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
684 6749 d 8 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
680 6753 d 1 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
576 6778 d 22 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
566 6780 d 23 h palkovsky /kernel/trunk/ Fixed bug in Intel32/AMD64 boot, that could cause page fault on boot.
Fixes of configuration program.
 
548 6782 d 3 h jermar /kernel/trunk/ Cleanup and fixes.  
540 6783 d 0 h jermar /kernel/trunk/arch/ Map all available frames of memory on ia32 and amd64 (ticket #10).  
534 6784 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6784 d 4 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6784 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
