2459 6203 d 16 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.
 
2454 6204 d 11 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2444 6209 d 9 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2441 6209 d 11 h decky /trunk/kernel/ fix ICC compilation  
2439 6209 d 11 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6209 d 12 h decky /trunk/ update for new compiler configuration scheme  
2317 6231 d 9 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6231 d 10 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6231 d 10 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2302 6236 d 15 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2233 6261 d 12 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2227 6262 d 3 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6262 d 12 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 6262 d 14 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6262 d 14 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 6263 d 9 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 6263 d 10 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 6263 d 13 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2125 6318 d 13 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6326 d 11 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 6326 d 19 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 6331 d 13 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6331 d 14 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2099 6331 d 15 h decky /trunk/kernel/arch/ia32/src/ explicit cast on pointer arithmetic  
2097 6331 d 15 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2095 6331 d 15 h decky /trunk/kernel/arch/ia32/src/smp/ fix signed/unsigned comparison  
2089 6332 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6333 d 15 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2083 6338 d 19 h decky /trunk/kernel/ typedef elimination  
2082 6338 d 20 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6339 d 14 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6343 d 12 h jermar /trunk/ (c) versus (C)  
2065 6357 d 11 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2057 6370 d 23 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2018 6380 d 15 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6382 d 12 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 6390 d 11 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 6391 d 17 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6399 d 20 h decky /trunk/ make framebuffer code more generic  
1970 6423 d 20 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()
