3987 5616 d 17 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.  
3985 5616 d 18 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5616 d 19 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.  
3982 5617 d 19 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5619 d 2 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 5619 d 14 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 5622 d 0 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5623 d 22 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5624 d 21 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
 
3946 5624 d 21 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5625 d 17 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5625 d 21 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3936 5625 d 22 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3932 5626 d 16 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3930 5626 d 16 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5626 d 16 h jermar /trunk/kernel/arch/ Introduce ioport8_t, ioport16_t and ioport32_t. These types are to be used with
pio_read_n() and pio_write_n() functions. This breaks everything.
 
3928 5626 d 18 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3908 5629 d 19 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5630 d 15 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.
 
3903 5630 d 22 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32 build for Pentium 3 systems.  
3902 5630 d 23 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.
 
3892 5631 d 17 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5631 d 17 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5631 d 18 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3889 5631 d 23 h svoboda /trunk/kernel/arch/ia32/include/drivers/ Make ia32/amd64 compile again. This is mostly a hack, but a more drastic cleanup is needed to do it the right way.  
3880 5633 d 18 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3879 5633 d 18 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5633 d 18 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3802 5657 d 22 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3800 5658 d 17 h decky /trunk/kernel/arch/ simplify compile options  
3790 5669 d 2 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 5669 d 15 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3779 5673 d 0 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5681 d 3 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3709 5691 d 19 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5691 d 19 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3706 5691 d 19 h decky /trunk/ cstyle & small fixes  
3672 5702 d 18 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5713 d 17 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.
 
3485 5763 d 17 h jermar /trunk/ Support for SYSENTER on ia32.
