1122 6681 d 13 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6681 d 17 h jermar /kernel/trunk/ Small textual changes.  
1119 6681 d 17 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1112 6682 d 4 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1102 6683 d 16 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6684 d 18 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 6685 d 0 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6685 d 1 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
1094 6685 d 3 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6687 d 20 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6688 d 13 h jermar /kernel/trunk/ Support for user space threads.  
1044 6689 d 1 h jermar /kernel/trunk/ Page table locking.  
1037 6689 d 3 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
983 6690 d 23 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6691 d 17 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6691 d 18 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 6691 d 19 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6692 d 20 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6693 d 6 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6702 d 14 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 6705 d 14 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.		  
853 6714 d 23 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 6715 d 0 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 6715 d 17 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6715 d 17 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
838 6719 d 3 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6719 d 4 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6719 d 15 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6722 d 22 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).		  
830 6723 d 0 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().		  
827 6723 d 15 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
820 6724 d 16 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
817 6725 d 0 h palkovsky /kernel/trunk/ Small cleanup.  
815 6725 d 1 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6725 d 2 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
812 6725 d 16 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
799 6726 d 17 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
797 6726 d 20 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6726 d 21 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.		  
794 6726 d 22 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.
