3973 5604 d 13 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 5605 d 1 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 5607 d 11 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5610 d 7 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 5611 d 3 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5611 d 7 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3922 5614 d 2 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 5614 d 2 h decky /trunk/kernel/generic/include/ add min3 and max3 macros  
3919 5614 d 2 h decky /trunk/kernel/generic/include/ cstyle  
3908 5615 d 6 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5616 d 1 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 5617 d 0 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3875 5619 d 4 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3844 5631 d 3 h decky /trunk/ silent kernel console output when user space console is active  
3838 5631 d 11 h decky /trunk/kernel/ make RANDI a generic macro  
3832 5632 d 9 h decky /trunk/kernel/generic/include/ print task name during fault  
3819 5637 d 4 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3790 5654 d 12 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 5655 d 2 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 5663 d 5 h decky /trunk/ send notification to uspace console when switching from kernel console  
3750 5666 d 13 h svoboda /trunk/kernel/generic/ Add memmove() function to kernel.  
3710 5677 d 3 h decky /trunk/ resurrect kernel logo  
3707 5677 d 5 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3702 5677 d 6 h decky /trunk/kernel/generic/include/ rename CONFIG_EDEBUG to CONFIG_LOG  
3683 5686 d 6 h svoboda /trunk/kernel/generic/ Rename udebug_thread_t.debug_active just to 'active'.  
3655 5694 d 4 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 5695 d 2 h jermar /trunk/kernel/generic/include/ Add host2uintX_t_{le|be} macros to the kernel's byteorder.  
3635 5698 d 4 h vana /trunk/ IA64: Userspace I/O support  
3622 5700 d 13 h svoboda /trunk/kernel/generic/include/udebug/ Remove unused debugging task state.  
3620 5700 d 14 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3617 5701 d 7 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3613 5701 d 13 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
3604 5702 d 2 h svoboda /trunk/kernel/generic/ Get rid of int_lock from udebug_thread_t, as is flawed.  
3601 5702 d 10 h svoboda /trunk/kernel/generic/ Replace 'stop' in udebug_thread_t with 'go' for consistency with nomenclature.  
3600 5702 d 10 h svoboda /trunk/kernel/generic/ Udebug comments - 'is go', not 'has go'. Missing periods.  
3578 5712 d 16 h vana /trunk/ Alfa of SMP support on IA64  
3566 5715 d 14 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5716 d 1 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 5727 d 5 h decky /trunk/kernel/generic/include/ coding style  
3446 5766 d 17 h svoboda /trunk/kernel/generic/include/ipc/ Fix: Rename ipc_kbox.h to kbox.h
