1135 6705 d 23 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1126 6707 d 9 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1122 6707 d 21 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.
 
1121 6708 d 0 h jermar /kernel/trunk/ Small textual changes.  
1119 6708 d 0 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1112 6708 d 11 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1102 6709 d 23 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6711 d 1 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 6711 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6711 d 8 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
1094 6711 d 11 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6714 d 4 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1066 6714 d 20 h jermar /kernel/trunk/ Support for user space threads.  
1044 6715 d 9 h jermar /kernel/trunk/ Page table locking.  
1037 6715 d 10 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
983 6717 d 6 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6718 d 1 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6718 d 2 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 6718 d 2 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6719 d 3 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6719 d 13 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6728 d 21 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 6731 d 22 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 6741 d 6 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 6741 d 7 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 6742 d 0 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6742 d 0 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
838 6745 d 11 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6745 d 11 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6745 d 22 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6749 d 5 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 6749 d 7 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 6749 d 22 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
820 6750 d 23 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 6751 d 8 h palkovsky /kernel/trunk/ Small cleanup.  
815 6751 d 8 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
814 6751 d 9 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
812 6751 d 23 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
799 6753 d 0 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
797 6753 d 4 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.
