1769 6532 d 1 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.		  
1760 6540 d 7 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1735 6545 d 12 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6545 d 22 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.		  
1705 6549 d 11 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6549 d 15 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6549 d 15 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6550 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1474 6563 d 0 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1410 6570 d 9 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.		  
1382 6574 d 1 h decky /kernel/trunk/ make hardware memory mapping more generic  
1376 6575 d 9 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.  
1288 6589 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.		  
1280 6592 d 3 h jermar /kernel/trunk/arch/ Get rid off obsolete ddi_int_control_arch() on ia64, sparc64 and ppc32.  
1265 6593 d 9 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1227 6601 d 7 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1223 6601 d 10 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1221 6602 d 0 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6608 d 9 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6610 d 14 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6611 d 5 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1135 6630 d 0 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1124 6631 d 12 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1062 6639 d 0 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
958 6642 d 3 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
901 6654 d 12 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
898 6655 d 9 h jermar /kernel/trunk/ Minor changes.  
897 6655 d 23 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
895 6656 d 2 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 6656 d 6 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6656 d 10 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
883 6657 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
877 6659 d 3 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6659 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
868 6661 d 8 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6661 d 8 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.		  
863 6661 d 23 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
847 6666 d 4 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6666 d 6 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
830 6673 d 8 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().
