3022 5842 d 22 h decky /branches/dd/ device drivers branch  
2861 5885 d 13 h cejka /trunk/ Used common macro for context saving on ppc64.  
2797 5898 d 13 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.		  
2794 5899 d 12 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2725 5955 d 18 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2723 5956 d 17 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 5956 d 19 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2467 6193 d 15 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6198 d 18 h jermar /trunk/ Merge arm32 into trunk.  
2454 6201 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.		  
2227 6259 d 2 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6259 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		  
2218 6260 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)		  
2216 6260 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2170 6267 d 10 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2125 6315 d 13 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6329 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6335 d 19 h decky /trunk/kernel/ typedef elimination  
2079 6336 d 14 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6340 d 12 h jermar /trunk/ (c) versus (C)  
2057 6367 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.		  
2023 6377 d 13 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6387 d 10 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 6388 d 17 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6396 d 20 h decky /trunk/ make framebuffer code more generic  
1949 6427 d 19 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6427 d 22 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1930 6432 d 17 h decky /trunk/kernel/arch/ppc64/ ppc64: make it compile again  
1901 6453 d 17 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 6461 d 10 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6461 d 21 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 6462 d 12 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 6465 d 15 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6466 d 19 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6481 d 21 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1837 6507 d 0 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1802 6525 d 8 h decky /trunk/ cleanup and unify the build system  
1787 6530 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6537 d 15 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6545 d 22 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
