3646 5665 d 20 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3635 5668 d 19 h vana /trunk/ IA64: Userspace I/O support  
3631 5669 d 18 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 5670 d 23 h vana /trunk/kernel/ Classic TLB shootdown support on ia64  
3622 5671 d 4 h svoboda /trunk/kernel/generic/include/udebug/ Remove unused debugging task state.  
3620 5671 d 4 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3619 5671 d 7 h vana /trunk/kernel/arch/ia64/src/smp/ IA64:smp.c Remove not important logs  
3617 5671 d 22 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3616 5671 d 22 h vana /trunk/ IA64 correctly find CPU wakeup vector from SAL & EFI memory map support  
3614 5672 d 4 h svoboda /trunk/kernel/generic/src/syscall/ Add another stopping point.  
3613 5672 d 4 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
3604 5672 d 17 h svoboda /trunk/kernel/generic/ Get rid of int_lock from udebug_thread_t, as is flawed.  
3603 5672 d 17 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3601 5673 d 1 h svoboda /trunk/kernel/generic/ Replace 'stop' in udebug_thread_t with 'go' for consistency with nomenclature.  
3600 5673 d 1 h svoboda /trunk/kernel/generic/ Udebug comments - 'is go', not 'has go'. Missing periods.  
3594 5675 d 19 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3587 5681 d 3 h jermar /trunk/kernel/arch/ppc64/src/mm/ Remove one more occurrence of "Page fault.\n".  
3586 5681 d 3 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5681 d 4 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 5681 d 5 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 5681 d 7 h vana /trunk/ IA64: Support for real frequency  
3581 5682 d 17 h jermar /trunk/kernel/ Some cstyle.  
3580 5682 d 17 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 5683 d 7 h vana /trunk/ Alfa of SMP support on IA64  
3577 5683 d 7 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3576 5683 d 8 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 5686 d 5 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5686 d 16 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 5697 d 20 h decky /trunk/kernel/generic/include/ coding style  
3496 5702 d 19 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5702 d 19 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5704 d 19 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3490 5713 d 22 h vana /trunk/kernel/arch/ia64/include/ Macro naming correction  
3486 5719 d 1 h decky /trunk/ faster compilation using -pipe  
3485 5719 d 18 h jermar /trunk/ Support for SYSENTER on ia32.  
3482 5722 d 19 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 5729 d 21 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3468 5731 d 7 h svoboda /trunk/kernel/generic/src/udebug/ Document functions in udebug_ipc.c  
3463 5735 d 0 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5735 d 19 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.
