4692 5435 d 22 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
4377 5535 d 21 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3624 5705 d 5 h svoboda /branches/tracing/kernel/ Move debbuging-related as functions to a separate module.  
3431 5772 d 20 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5773 d 7 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3036 5880 d 0 h svoboda /branches/tracing/kernel/generic/ Make sure area written by debugger is private and anonymous by copying it, if necessary. (Not atomic atm)  
3013 5884 d 8 h svoboda /branches/tracing/kernel/generic/ Bypass area write-protection for udebug memory writes.  
2787 5946 d 1 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 5975 d 5 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5996 d 3 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)
 
2556 6126 d 6 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6239 d 2 h jermar /trunk/ Merge arm32 into trunk.  
2444 6246 d 17 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2183 6303 d 1 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
 
2170 6307 d 19 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.
 
2142 6311 d 2 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6355 d 18 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6355 d 21 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6355 d 23 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6362 d 1 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6363 d 20 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 6364 d 4 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.
 
2094 6368 d 23 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6369 d 0 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6370 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6376 d 2 h decky /trunk/kernel/ typedef elimination  
2083 6376 d 3 h decky /trunk/kernel/ typedef elimination  
2071 6380 d 20 h jermar /trunk/ (c) versus (C)  
2059 6404 d 5 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2015 6419 d 21 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.
 
2009 6424 d 20 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6427 d 19 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.
 
2001 6430 d 18 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6431 d 6 h decky /trunk/kernel/ move files to more proper locations  
1999 6431 d 6 h decky /trunk/ start RAM disk support  
1951 6467 d 23 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6467 d 23 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6472 d 0 h decky /trunk/kernel/generic/include/ cleanup  
1914 6482 d 2 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1891 6501 d 19 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
