1968 6422 d 21 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1963 6422 d 22 h jermar /tags/0.1.1/ Tagging release 0.1.1  
1354 6587 d 5 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1332 6588 d 23 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1293 6598 d 4 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6598 d 8 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1278 6601 d 1 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1260 6603 d 21 h palkovsky /kernel/trunk/ Small fixes.  
1258 6603 d 21 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.		  
1227 6610 d 3 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1223 6610 d 7 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6610 d 20 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1221 6610 d 20 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6611 d 1 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1196 6617 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6619 d 10 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6620 d 2 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1135 6638 d 21 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1126 6640 d 7 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1122 6640 d 19 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6640 d 22 h jermar /kernel/trunk/ Small textual changes.  
1119 6640 d 22 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1112 6641 d 9 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1102 6642 d 21 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6643 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 6644 d 6 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6644 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 6644 d 9 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6647 d 1 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6647 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1044 6648 d 7 h jermar /kernel/trunk/ Page table locking.  
1037 6648 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
983 6650 d 4 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6650 d 23 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6650 d 23 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 6651 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6652 d 1 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6652 d 11 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6661 d 19 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 6664 d 19 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.
