1100 6690 d 3 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 6690 d 9 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6690 d 10 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
1094 6690 d 12 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1087 6691 d 12 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1078 6693 d 5 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1070 6693 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6693 d 22 h jermar /kernel/trunk/ Support for user space threads.  
1055 6694 d 6 h cejka /kernel/trunk/arch/mips32/include/ Stack constants moved to stack.h as on other archs.  
1054 6694 d 6 h cejka /kernel/trunk/ Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary.		  
1044 6694 d 10 h jermar /kernel/trunk/ Page table locking.  
1037 6694 d 12 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1036 6694 d 12 h decky /kernel/trunk/arch/mips32/ grow init size  
1024 6695 d 4 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1017 6695 d 8 h decky /kernel/trunk/ mips: remove load.bin
remove arch/boot infrastructure		  
983 6696 d 8 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6696 d 9 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6696 d 9 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6696 d 13 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6697 d 2 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6697 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.		  
955 6697 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
941 6698 d 4 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6698 d 4 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6698 d 5 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6698 d 15 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
910 6705 d 10 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6707 d 23 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 6710 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.		  
860 6717 d 23 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
853 6720 d 8 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 6720 d 9 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 6721 d 2 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6721 d 2 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6721 d 2 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
838 6724 d 12 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6724 d 13 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6725 d 0 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
832 6728 d 1 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6728 d 7 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
