3973 5582 d 11 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()		  
3940 5589 d 6 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5593 d 4 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3790 5632 d 11 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.  
3193 5824 d 2 h jermar /trunk/kernel/ cstyle fixes  
3071 5851 d 8 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2222 6273 d 2 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2071 6354 d 2 h jermar /trunk/ (c) versus (C)  
1787 6544 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6551 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1730 6567 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup		  
1726 6568 d 5 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)		  
1708 6569 d 12 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6572 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1609 6579 d 9 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1411 6592 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.		  
1390 6595 d 4 h decky /kernel/trunk/arch/ppc32/src/mm/ fixes  
1389 6595 d 4 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1384 6596 d 0 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support		  
1383 6596 d 1 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6597 d 9 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6597 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
793 6699 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.		  
684 6728 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.		  
534 6763 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6763 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6775 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
342 6846 d 9 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
163 6872 d 9 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6872 d 11 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script
