1837 6550 d 18 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1790 6572 d 9 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1787 6574 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6575 d 6 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6581 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6602 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1474 6615 d 4 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1423 6619 d 13 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1382 6626 d 5 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6626 d 7 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.
 
1376 6627 d 13 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.  
1371 6628 d 5 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer
 
1327 6632 d 12 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1313 6633 d 14 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 6660 d 13 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1135 6682 d 4 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1108 6685 d 4 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
977 6693 d 12 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
902 6706 d 14 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 6708 d 6 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 6708 d 9 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
867 6713 d 12 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 6721 d 16 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6721 d 16 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
832 6725 d 4 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
811 6728 d 6 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.
 
810 6728 d 11 h cejka /kernel/trunk/genarch/ Added softint for emulation 32 and 64 bit division.
Not tested yet.
 
793 6729 d 11 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 6729 d 12 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
760 6733 d 14 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 6735 d 3 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 6736 d 2 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 6740 d 12 h jermar /kernel/trunk/ Page hash table modifications.  
730 6745 d 9 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
699 6756 d 13 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.
 
684 6758 d 12 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 6767 d 4 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().
 
534 6793 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6793 d 7 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
515 6803 d 8 h jermar /kernel/trunk/ SMP cleanup continued.
Add nice type for IO APIC ID register.
Replace some magic numbers with more descriptive macros.
