3635 5691 d 13 h vana /trunk/ IA64: Userspace I/O support  
3631 5692 d 12 h jermar /trunk/kernel/arch/ia32/src/ The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel.		  
3626 5693 d 17 h vana /trunk/kernel/ Classic TLB shootdown support on ia64  
3622 5693 d 22 h svoboda /trunk/kernel/generic/include/udebug/ Remove unused debugging task state.  
3620 5693 d 22 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3619 5694 d 0 h vana /trunk/kernel/arch/ia64/src/smp/ IA64:smp.c Remove not important logs  
3617 5694 d 16 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3616 5694 d 16 h vana /trunk/ IA64 correctly find CPU wakeup vector from SAL & EFI memory map support  
3614 5694 d 22 h svoboda /trunk/kernel/generic/src/syscall/ Add another stopping point.  
3613 5694 d 22 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
3604 5695 d 11 h svoboda /trunk/kernel/generic/ Get rid of int_lock from udebug_thread_t, as is flawed.  
3603 5695 d 11 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3601 5695 d 18 h svoboda /trunk/kernel/generic/ Replace 'stop' in udebug_thread_t with 'go' for consistency with nomenclature.  
3600 5695 d 19 h svoboda /trunk/kernel/generic/ Udebug comments - 'is go', not 'has go'. Missing periods.  
3594 5698 d 13 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3587 5703 d 20 h jermar /trunk/kernel/arch/ppc64/src/mm/ Remove one more occurrence of "Page fault.\n".  
3586 5703 d 20 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5703 d 22 h svoboda /trunk/ Fix bug #67. It was obviously all my fault - I allocated r3 for pcb_ptr, which was alredy used by uarg.  
3584 5703 d 22 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Bugfix: A ppc32 task would hang if it touched unmapped memory - was calling printf() with address-space mutex held.  
3583 5704 d 1 h vana /trunk/ IA64: Support for real frequency  
3581 5705 d 10 h jermar /trunk/kernel/ Some cstyle.  
3580 5705 d 11 h jermar /trunk/kernel/arch/sparc64/include/ Accesses to memory mapped registers should use volatile pointers so that
the compiler doesn't even think of trying to be clever. Add memory barriers
and fixed cstyle.		  
3578 5706 d 1 h vana /trunk/ Alfa of SMP support on IA64  
3577 5706 d 1 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3576 5706 d 2 h vana /trunk/kernel/generic/src/main/ On Itanium there is nead to preserve at least gp when switching APs to separate stack. Safer way is to save all context and to do it on all platforms.  
3566 5708 d 23 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5709 d 10 h svoboda /trunk/ Fix sys_thread_create(): could fail when passed name was at end of mapping, could crash if provided name was not null-terminated.  
3522 5720 d 13 h decky /trunk/kernel/generic/include/ coding style  
3496 5725 d 13 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5725 d 13 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5727 d 12 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3490 5736 d 15 h vana /trunk/kernel/arch/ia64/include/ Macro naming correction  
3486 5741 d 19 h decky /trunk/ faster compilation using -pipe  
3485 5742 d 12 h jermar /trunk/ Support for SYSENTER on ia32.  
3482 5745 d 13 h jermar /trunk/kernel/arch/sparc64/ Do not allocate full page for the uspace window buffer.
Instead, allocate only the bare minimum to fit NWINDOWS - 1
uspace windows and to satisfy alignment requirements.		  
3476 5752 d 15 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3468 5754 d 1 h svoboda /trunk/kernel/generic/src/udebug/ Document functions in udebug_ipc.c  
3463 5757 d 18 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5758 d 12 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3457 5758 d 14 h svoboda /trunk/kernel/generic/src/udebug/ Document functions in udebug.c and udebug_ops.c
