1615 6555 d 5 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1595 6555 d 14 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1537 6558 d 21 h palkovsky /kernel/trunk/ Added tetris to  
1474 6560 d 23 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6561 d 23 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1434 6564 d 3 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1432 6564 d 10 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1411 6568 d 4 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1396 6571 d 1 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1386 6571 d 7 h palkovsky /kernel/trunk/ Fixed mips bug fith TLS register not being properly saved on syscall context
switch.
Reverted SYS_IO, so that it could be used on machines without fb.		  
1354 6576 d 6 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1332 6578 d 1 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1293 6587 d 6 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6587 d 9 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 6590 d 3 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1260 6592 d 23 h palkovsky /kernel/trunk/ Small fixes.  
1258 6592 d 23 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 6599 d 5 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 6599 d 9 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6599 d 22 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1221 6599 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6600 d 3 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1196 6606 d 8 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6608 d 12 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6609 d 4 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 6627 d 23 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1126 6629 d 9 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1122 6629 d 21 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6630 d 0 h jermar /kernel/trunk/ Small textual changes.  
1119 6630 d 0 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1112 6630 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 6631 d 23 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6633 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 6633 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6633 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 6633 d 10 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6636 d 3 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6636 d 20 h jermar /kernel/trunk/ Support for user space threads.  
1044 6637 d 8 h jermar /kernel/trunk/ Page table locking.  
1037 6637 d 10 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
