2218 6393 d 18 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2217 6393 d 19 h jermar /trunk/kernel/arch/ia32/src/smp/ On SMP amd64 and ia32 systems, release the irq->lock
before calling clock() from the interrupt handler.
This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held.
 
2125 6448 d 22 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6456 d 20 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2106 6457 d 4 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2101 6461 d 22 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6461 d 23 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6462 d 0 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6462 d 0 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6462 d 0 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2089 6463 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6464 d 0 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2082 6469 d 5 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6473 d 21 h jermar /trunk/ (c) versus (C)  
2065 6487 d 20 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6511 d 0 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6512 d 21 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
1993 6530 d 5 h decky /trunk/ make framebuffer code more generic  
1970 6554 d 5 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()  
1957 6556 d 5 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6556 d 7 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6565 d 1 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6565 d 8 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6587 d 3 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.
 
1888 6599 d 1 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1877 6604 d 8 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.
 
1854 6615 d 7 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.
 
1842 6635 d 4 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.
 
1837 6640 d 9 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1811 6651 d 5 h decky /trunk/kernel/arch/ unify bootstrapping  
1793 6661 d 6 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1787 6663 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6671 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6679 d 8 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6682 d 2 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1754 6685 d 6 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1735 6687 d 7 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6687 d 17 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.
 
1724 6688 d 10 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1708 6689 d 6 h jermar /kernel/trunk/ Fix some broken doxygen comments.
