2316 6247 d 17 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6247 d 17 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2302 6252 d 22 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2233 6277 d 19 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2227 6278 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6278 d 19 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 6278 d 21 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6278 d 21 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 6279 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 6279 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.
 
2216 6279 d 20 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2125 6334 d 20 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6342 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 6343 d 3 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 6347 d 21 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6347 d 21 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6347 d 22 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6347 d 22 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6347 d 22 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2089 6349 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6349 d 22 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2083 6355 d 2 h decky /trunk/kernel/ typedef elimination  
2082 6355 d 3 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6355 d 21 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6359 d 19 h jermar /trunk/ (c) versus (C)  
2065 6373 d 18 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2057 6387 d 7 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2018 6396 d 22 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6398 d 20 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.
 
2007 6406 d 18 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.
 
2003 6408 d 0 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6416 d 3 h decky /trunk/ make framebuffer code more generic  
1970 6440 d 3 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()  
1957 6442 d 3 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6442 d 5 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6450 d 23 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6451 d 6 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6473 d 1 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.
 
1891 6480 d 18 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6481 d 4 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.
