2454 6210 d 21 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.		  
2227 6268 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6268 d 22 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2218 6269 d 19 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)		  
2216 6269 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2125 6324 d 23 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2107 6332 d 21 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 6333 d 5 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 6337 d 23 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2089 6339 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6345 d 6 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6349 d 22 h jermar /trunk/ (c) versus (C)  
2018 6387 d 1 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6387 d 5 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2014 6391 d 0 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2007 6396 d 21 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.		  
1959 6432 d 5 h decky /trunk/kernel/arch/ia32xen/src/ ia32xen: adopt new IRQ interface  
1953 6437 d 0 h jermar /trunk/kernel/ Finish renaming xen32 to ia32xen.  
1952 6437 d 0 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1943 6440 d 10 h decky /trunk/kernel/arch/xen32/src/ xen32: fix compilation  
1937 6441 d 9 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6463 d 4 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 6470 d 21 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6471 d 7 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.		  
1889 6471 d 23 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6475 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1840 6511 d 19 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1836 6518 d 7 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6518 d 18 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6518 d 18 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6518 d 19 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6518 d 19 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6518 d 22 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6518 d 22 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6518 d 23 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6518 d 23 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6519 d 1 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1821 6521 d 3 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6525 d 22 h decky /trunk/kernel/ make burst updates  
1817 6526 d 18 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
