2015 6382 d 11 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.
 
2005 6391 d 16 h decky /trunk/ update rd  
2002 6391 d 17 h decky /trunk/kernel/generic/ rd work  
2000 6393 d 20 h decky /trunk/kernel/ move files to more proper locations  
1999 6393 d 20 h decky /trunk/ start RAM disk support  
1901 6456 d 16 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.
 
1894 6463 d 8 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel
 
1855 6484 d 16 h jermar /trunk/kernel/ sparc64 work.

Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.

Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer.
 
1854 6484 d 20 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.
 
1833 6512 d 6 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6512 d 13 h decky /trunk/kernel/generic/src/main/ some debugging output  
1787 6533 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6540 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6554 d 19 h jermar /kernel/trunk/ Cleanup of comments.  
1729 6557 d 7 h decky /kernel/trunk/generic/src/main/ coding style changes  
1705 6560 d 20 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6561 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1662 6566 d 22 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1659 6566 d 23 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1595 6569 d 0 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
