4605 5657 d 12 h decky /branches/snapshot/ add task snapshoting branch  
3130 6042 d 18 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 6043 d 7 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.
 
2222 6473 d 5 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2089 6543 d 12 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6554 d 5 h jermar /trunk/ (c) versus (C)  
1787 6744 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6751 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6765 d 13 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6772 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1248 6819 d 8 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6822 d 13 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1221 6824 d 3 h decky /kernel/trunk/ printf-related and other code cleanup  
1044 6861 d 13 h jermar /kernel/trunk/ Page table locking.  
826 6896 d 4 h jermar /kernel/trunk/ Add page_mapping_remove().  
793 6899 d 10 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 6905 d 2 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 6906 d 1 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.
 
703 6923 d 13 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
699 6926 d 12 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.
 
687 6928 d 9 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
684 6928 d 11 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.
 
654 6947 d 8 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.
 
548 6961 d 6 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6963 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6963 d 6 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 6963 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6975 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6976 d 3 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
430 6996 d 3 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
391 7024 d 4 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
251 7056 d 1 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
226 7057 d 11 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
 
195 7059 d 6 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
 
158 7078 d 11 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment  
157 7078 d 11 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
125 7105 d 4 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 7120 d 2 h jermar /SPARTAN/trunk/ Generic 4-level page tables interface & implementation (review & test).
Implement more architecture dependant macros on IA-32.
Provide fake implementation on IA-64 and MIPS.
Convert map_page_to_frame() to use the new interface.
Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
 
116 7140 d 9 h jermar /SPARTAN/trunk/ Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().

Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT.
 
23 7192 d 9 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.
