1102 6661 d 3 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6662 d 5 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1097 6662 d 12 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6662 d 12 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
1094 6662 d 15 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1087 6663 d 15 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1078 6665 d 7 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1070 6665 d 16 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6666 d 0 h jermar /kernel/trunk/ Support for user space threads.  
1055 6666 d 8 h cejka /kernel/trunk/arch/mips32/include/ Stack constants moved to stack.h as on other archs.  
1054 6666 d 8 h cejka /kernel/trunk/ Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary.
 
1044 6666 d 13 h jermar /kernel/trunk/ Page table locking.  
1037 6666 d 14 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
1036 6666 d 14 h decky /kernel/trunk/arch/mips32/ grow init size  
1024 6667 d 7 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1017 6667 d 10 h decky /kernel/trunk/ mips: remove load.bin
remove arch/boot infrastructure
 
983 6668 d 10 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6668 d 11 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
 
977 6668 d 11 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6668 d 15 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6669 d 5 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6669 d 5 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.
 
955 6669 d 6 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
941 6670 d 7 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6670 d 7 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6670 d 7 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6670 d 17 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
910 6677 d 12 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6680 d 1 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared
 
897 6683 d 2 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.
 
860 6690 d 2 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
853 6692 d 10 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.
 
852 6692 d 11 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
 
851 6693 d 4 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6693 d 4 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6693 d 4 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
838 6696 d 15 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6696 d 15 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6697 d 2 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
832 6700 d 3 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.
