4117 5594 d 4 h decky /trunk/ arm32: update for the new scheme of device drivers and keyboard/serial modules
streamline arm32 port (as GXemul is still the only machine supported), more cleanup is needed
 
4045 5599 d 7 h jermar /trunk/kernel/arch/arm32/ Remove ARM's console_init() because it conflicts with the generic
console_init(). No functionality loss as it was a mere wrapper around
machine_console_init().
 
4027 5603 d 4 h svoboda /trunk/ Init task names for arm32.  
4021 5603 d 6 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4018 5603 d 11 h decky /trunk/kernel/arch/arm32/ better inline assembler readability using the new symbolic syntax  
3973 5607 d 15 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()
 
3952 5613 d 6 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3949 5613 d 8 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3940 5614 d 10 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5615 d 5 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.
 
3922 5617 d 4 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
 
3917 5617 d 5 h decky /trunk/ remove non-standard define  
3908 5618 d 8 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5619 d 11 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.
 
3880 5622 d 7 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3878 5622 d 7 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3844 5634 d 6 h decky /trunk/ silent kernel console output when user space console is active  
3416 5773 d 10 h svoboda /trunk/kernel/arch/arm32/include/ Merge changeset 3122 from tracing to trunk. (Add missing include)  
3233 5822 d 12 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3134 5865 d 16 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5866 d 6 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5873 d 19 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3094 5875 d 8 h svoboda /trunk/ Make arm32 compile again.  
3070 5876 d 12 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
2797 5937 d 7 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5938 d 7 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2725 5994 d 13 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2721 5995 d 13 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2467 6232 d 9 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6237 d 12 h jermar /trunk/ Merge arm32 into trunk.  
2216 6299 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2128 6353 d 8 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.
