4016 5594 d 7 h decky /trunk/kernel/ better inline assembler readability using the new symbolic syntax  
4015 5594 d 10 h decky /trunk/kernel/arch/ia32/ rename ia32_cboot() to arch_pre_main() and move it to ia32.c (to be in line with other platforms)  
4014 5594 d 10 h decky /trunk/ cstyle  
4012 5595 d 0 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5595 d 1 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5596 d 2 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 5596 d 3 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5596 d 3 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 5597 d 4 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5598 d 11 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 5598 d 23 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 5601 d 9 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5603 d 7 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5604 d 5 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 5605 d 2 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5605 d 5 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3932 5606 d 0 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3930 5606 d 1 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3908 5609 d 4 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5609 d 23 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 5610 d 7 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 5611 d 1 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5611 d 2 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5611 d 2 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5613 d 2 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3802 5637 d 7 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5648 d 10 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 5649 d 0 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 5652 d 8 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5660 d 11 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 5671 d 3 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5671 d 4 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3672 5682 d 3 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5693 d 1 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 5743 d 1 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5799 d 7 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3240 5809 d 12 h decky / move unfinished ObjC support to a separate branch  
3234 5813 d 7 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5814 d 3 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3222 5832 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)
