2302 6259 d 22 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2233 6284 d 18 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2227 6285 d 9 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6285 d 18 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6285 d 20 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6285 d 20 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
 
2218 6286 d 16 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 6286 d 17 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 6341 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6349 d 18 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 6350 d 2 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 6354 d 20 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6354 d 21 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6354 d 21 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6354 d 21 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6354 d 22 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2089 6356 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6356 d 22 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2082 6362 d 2 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6366 d 19 h jermar /trunk/ (c) versus (C)  
2065 6380 d 17 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6403 d 22 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6405 d 19 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 6423 d 3 h decky /trunk/ make framebuffer code more generic  
1970 6447 d 3 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()  
1957 6449 d 3 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6449 d 4 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6457 d 22 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6458 d 5 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6480 d 0 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 6491 d 22 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1877 6497 d 6 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.
 
1854 6508 d 4 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 6528 d 2 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 6533 d 7 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 6544 d 3 h decky /trunk/kernel/arch/ unify bootstrapping  
1793 6554 d 4 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 6556 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6563 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6572 d 5 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.
