2018 6361 d 13 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6363 d 10 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 6371 d 8 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 6372 d 15 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6380 d 18 h decky /trunk/ make framebuffer code more generic  
1970 6404 d 18 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()  
1957 6406 d 18 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6406 d 19 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6415 d 13 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6415 d 20 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6437 d 15 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 6445 d 8 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6445 d 19 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 6446 d 10 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 6449 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6450 d 17 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1877 6454 d 21 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1854 6465 d 19 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.		  
1844 6485 d 12 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).		  
1842 6485 d 17 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.
