1474 6547 d 20 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1423 6552 d 5 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1382 6558 d 22 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6558 d 23 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1376 6560 d 6 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.  
1371 6560 d 21 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer		  
1327 6565 d 4 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1313 6566 d 6 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().		  
1196 6593 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1135 6614 d 20 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1108 6617 d 20 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
977 6626 d 5 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
902 6639 d 6 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
895 6640 d 22 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
894 6641 d 2 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
867 6646 d 4 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
838 6654 d 8 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6654 d 9 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
832 6657 d 20 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
811 6660 d 22 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
810 6661 d 3 h cejka /kernel/trunk/genarch/ Added softint for emulation 32 and 64 bit division.
Not tested yet.		  
793 6662 d 4 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.		  
792 6662 d 4 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
760 6666 d 6 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
756 6667 d 19 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 6668 d 18 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.		  
746 6673 d 5 h jermar /kernel/trunk/ Page hash table modifications.  
730 6678 d 1 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
699 6689 d 5 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
684 6691 d 4 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.		  
669 6699 d 20 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
534 6725 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6725 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
515 6736 d 0 h jermar /kernel/trunk/ SMP cleanup continued.
Add nice type for IO APIC ID register.
Replace some magic numbers with more descriptive macros.		  
501 6738 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
494 6738 d 20 h jermar /SPARTAN/trunk/genarch/ Remove genarch/{src|include}/firmware.  
493 6738 d 20 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
452 6752 d 23 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient		  
426 6761 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.		  
424 6762 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Link kernel with load address 0x4000.
Add fragment of Linux image header to force SILO to always load the kernel at 0x4000.
Adjust ofw.h and ofw.c to work also on sparc64.
