2220 6263 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 6264 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 6264 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 6319 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2107 6327 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 6328 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 6332 d 20 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6332 d 21 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6332 d 21 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6332 d 21 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6332 d 22 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2089 6334 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2087 6334 d 22 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2082 6340 d 2 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6344 d 19 h jermar /trunk/ (c) versus (C)  
2065 6358 d 17 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6381 d 22 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6383 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 6401 d 3 h decky /trunk/ make framebuffer code more generic  
1970 6425 d 3 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()
