3983 5655 d 18 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3973 5657 d 22 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3972 5658 d 9 h decky /trunk/kernel/ kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism		  
3964 5660 d 20 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5663 d 16 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers		  
3941 5664 d 12 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5664 d 16 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3922 5667 d 10 h decky /trunk/ make arch_pre_main optional, don't force any specific prototype
simplify boot process
mips32: detect number of configured CPUs in msim		  
3920 5667 d 10 h decky /trunk/kernel/generic/include/ add min3 and max3 macros  
3919 5667 d 10 h decky /trunk/kernel/generic/include/ cstyle  
3908 5668 d 14 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5669 d 10 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.		  
3896 5670 d 9 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3875 5672 d 13 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3844 5684 d 12 h decky /trunk/ silent kernel console output when user space console is active  
3838 5684 d 20 h decky /trunk/kernel/ make RANDI a generic macro  
3832 5685 d 17 h decky /trunk/kernel/generic/include/ print task name during fault  
3819 5690 d 13 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3790 5707 d 21 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5708 d 10 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3761 5716 d 13 h decky /trunk/ send notification to uspace console when switching from kernel console  
3750 5719 d 22 h svoboda /trunk/kernel/generic/ Add memmove() function to kernel.  
3710 5730 d 12 h decky /trunk/ resurrect kernel logo  
3707 5730 d 14 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3702 5730 d 14 h decky /trunk/kernel/generic/include/ rename CONFIG_EDEBUG to CONFIG_LOG  
3683 5739 d 14 h svoboda /trunk/kernel/generic/ Rename udebug_thread_t.debug_active just to 'active'.  
3655 5747 d 13 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.		  
3648 5748 d 10 h jermar /trunk/kernel/generic/include/ Add host2uintX_t_{le|be} macros to the kernel's byteorder.  
3635 5751 d 13 h vana /trunk/ IA64: Userspace I/O support  
3622 5753 d 22 h svoboda /trunk/kernel/generic/include/udebug/ Remove unused debugging task state.  
3620 5753 d 22 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3617 5754 d 16 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3613 5754 d 22 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
3604 5755 d 11 h svoboda /trunk/kernel/generic/ Get rid of int_lock from udebug_thread_t, as is flawed.  
3601 5755 d 18 h svoboda /trunk/kernel/generic/ Replace 'stop' in udebug_thread_t with 'go' for consistency with nomenclature.  
3600 5755 d 19 h svoboda /trunk/kernel/generic/ Udebug comments - 'is go', not 'has go'. Missing periods.  
3578 5766 d 1 h vana /trunk/ Alfa of SMP support on IA64  
3566 5768 d 23 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5769 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 5780 d 13 h decky /trunk/kernel/generic/include/ coding style
