3987 5602 d 22 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3984 5602 d 23 h svoboda /trunk/kernel/ The ia32-specific boot code is written completely in assembly for no reason. Start fixing this. For now rewrite the copying of multiboot info to C.  
3983 5603 d 4 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3974 5605 d 6 h decky /trunk/kernel/generic/src/console/ prettyprint help and tests  
3973 5605 d 7 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 19 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
 
3968 5606 d 22 h jermar /trunk/kernel/generic/src/ddi/ Fix argument order.  
3965 5607 d 23 h svoboda /trunk/kernel/generic/src/ Fix broken doxygen syntax.  
3964 5608 d 5 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3950 5611 d 0 h jermar /trunk/kernel/generic/src/ddi/ Fix UP builds.  
3947 5611 d 1 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 22 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5612 d 2 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3930 5612 d 21 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3913 5615 d 5 h decky /trunk/ mips32: basic SMP support  
3908 5616 d 0 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5616 d 20 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.
 
3902 5617 d 3 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.
 
3896 5617 d 19 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 23 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3870 5621 d 7 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro  
3867 5622 d 5 h svoboda /trunk/kernel/generic/src/ipc/ Bugfix: Check kbox, not regular box. In case where the debugger disconnected first and then the application terminated, the application task would not be cleaned up.  
3865 5623 d 20 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3860 5629 d 5 h decky /trunk/kernel/generic/src/main/ add dot which will be erased  
3844 5631 d 21 h decky /trunk/ silent kernel console output when user space console is active  
3842 5632 d 0 h decky /trunk/kernel/generic/src/ make sys_klog atomic  
3840 5632 d 5 h decky /trunk/kernel/generic/src/main/ more decent kconsole output without stdin  
3828 5634 d 1 h decky /trunk/kernel/generic/src/main/ print numbers, not "llu"  
3819 5637 d 23 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3790 5655 d 7 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 20 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 23 h decky /trunk/ send notification to uspace console when switching from kernel console  
3750 5667 d 7 h svoboda /trunk/kernel/generic/ Add memmove() function to kernel.  
3734 5670 d 5 h decky /trunk/kernel/generic/src/proc/ coding style  
3707 5678 d 0 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3683 5687 d 0 h svoboda /trunk/kernel/generic/ Rename udebug_thread_t.debug_active just to 'active'.  
3680 5687 d 5 h svoboda /trunk/kernel/generic/src/time/ Fix panic caused by NULL pointer dereference.  
3657 5694 d 7 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3655 5694 d 22 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.
 
3626 5701 d 3 h vana /trunk/kernel/ Classic TLB shootdown support on ia64
