1100 6702 d 23 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 6703 d 6 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6703 d 6 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
1094 6703 d 9 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1087 6704 d 9 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fix MIPS32 bad paging index computation. Fixed random page faults on mips.  
1078 6706 d 2 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1070 6706 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6706 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1055 6707 d 2 h cejka /kernel/trunk/arch/mips32/include/ Stack constants moved to stack.h as on other archs.  
1054 6707 d 3 h cejka /kernel/trunk/ Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary.		  
1044 6707 d 7 h jermar /kernel/trunk/ Page table locking.  
1037 6707 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1036 6707 d 9 h decky /kernel/trunk/arch/mips32/ grow init size  
1024 6708 d 1 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1017 6708 d 5 h decky /kernel/trunk/ mips: remove load.bin
remove arch/boot infrastructure		  
983 6709 d 5 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6709 d 6 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6709 d 6 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6709 d 9 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6709 d 23 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6710 d 0 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 6710 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
941 6711 d 1 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6711 d 1 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6711 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6711 d 11 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
910 6718 d 7 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6720 d 20 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 6723 d 20 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 6730 d 20 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
853 6733 d 4 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 6733 d 5 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 6733 d 22 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6733 d 22 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6733 d 23 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
838 6737 d 9 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6737 d 10 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6737 d 21 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
832 6740 d 21 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6741 d 4 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).
