2599 6047 d 6 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2467 6197 d 12 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6202 d 14 h jermar /trunk/ Merge arm32 into trunk.  
2462 6204 d 9 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.		  
2460 6204 d 10 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.		  
2459 6204 d 13 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.		  
2457 6204 d 13 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2454 6205 d 8 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 6262 d 23 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6263 d 9 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 6264 d 6 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 6264 d 9 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2125 6319 d 9 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2107 6327 d 8 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 6327 d 16 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 10 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2089 6333 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6339 d 16 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6344 d 9 h jermar /trunk/ (c) versus (C)  
2018 6381 d 12 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6381 d 15 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2014 6385 d 11 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2007 6391 d 7 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 6426 d 16 h decky /trunk/kernel/arch/ia32xen/src/ ia32xen: adopt new IRQ interface  
1953 6431 d 11 h jermar /trunk/kernel/ Finish renaming xen32 to ia32xen.  
1952 6431 d 11 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1943 6434 d 20 h decky /trunk/kernel/arch/xen32/src/ xen32: fix compilation  
1937 6435 d 20 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6457 d 14 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 6465 d 7 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6465 d 18 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 6466 d 9 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 6469 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1840 6506 d 5 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1836 6512 d 17 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6513 d 5 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6513 d 5 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6513 d 6 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6513 d 6 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6513 d 8 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts
