2474 6194 d 18 h jermar /tags/0.2.0.5/ Add tag for HelenOS 0.2.0.5.  
2467 6199 d 23 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6205 d 1 h jermar /trunk/ Merge arm32 into trunk.  
2454 6207 d 19 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 6265 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6265 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		  
2218 6266 d 17 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 6266 d 20 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2170 6273 d 18 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 6321 d 20 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6336 d 3 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6342 d 3 h decky /trunk/kernel/ typedef elimination  
2079 6342 d 21 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6346 d 20 h jermar /trunk/ (c) versus (C)  
2057 6374 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.		  
2033 6382 d 2 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2023 6383 d 21 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6393 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 6395 d 1 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6403 d 4 h decky /trunk/ make framebuffer code more generic  
1949 6434 d 3 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6434 d 6 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6436 d 23 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1934 6438 d 8 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6438 d 20 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.		  
1928 6439 d 1 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6439 d 6 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1901 6460 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 6467 d 18 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6468 d 5 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 6468 d 20 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 6471 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6473 d 3 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6488 d 5 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 6513 d 8 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 6531 d 15 h decky /trunk/ cleanup and unify the build system  
1790 6534 d 23 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1787 6536 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6543 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1762 6553 d 16 h decky /kernel/trunk/arch/ppc32/src/cpu/ ppc32 identify known CPUs
