1495 7160 d 18 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.
 
1210 7202 d 6 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1191 7209 d 10 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1106 7231 d 21 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1059 7237 d 23 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.
 
1053 7238 d 2 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
938 7242 d 0 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
919 7245 d 6 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.
 
901 7253 d 8 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.
 
811 7274 d 22 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.
 
756 7281 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.
 
753 7283 d 2 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
 
740 7289 d 4 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 7293 d 21 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
684 7305 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.
 
674 7309 d 7 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
583 7334 d 4 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
539 7339 d 0 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.
 
534 7339 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 7339 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
519 7346 d 21 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 7352 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 7359 d 20 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 7359 d 23 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
470 7365 d 17 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.
 
457 7366 d 7 h decky /SPARTAN/trunk/ new build system almost finished  
455 7366 d 19 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
435 7368 d 22 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
 
431 7371 d 7 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
430 7372 d 21 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
376 7410 d 2 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
368 7414 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
326 7425 d 18 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
293 7430 d 19 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
289 7430 d 23 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
272 7432 d 1 h vana /SPARTAN/trunk/arch/ia64/ Symtab support for ia64  
230 7434 d 3 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
212 7434 d 21 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
195 7435 d 23 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
 
161 7451 d 7 h jermar /SPARTAN/trunk/arch/ For all relevant architectures, rename fake.s to dummy.s to better reflect the purpose of the file.
Also define global symbol called dummy.
