3675 5811 d 23 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3624 5824 d 9 h svoboda /branches/tracing/kernel/ Move debbuging-related as functions to a separate module.  
3597 5826 d 23 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3596 5828 d 2 h svoboda /branches/tracing/kernel/generic/src/mm/ Update obsolete comment.  
3431 5892 d 0 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5892 d 11 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5892 d 23 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3127 5989 d 23 h svoboda /branches/tracing/kernel/generic/src/ Fix rounding error in as_debug_write() - prevent panic when writing on page boundary  
3036 5999 d 4 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 6003 d 12 h svoboda /branches/tracing/kernel/generic/ Bypass area write-protection for udebug memory writes.  
3011 6004 d 23 h svoboda /branches/tracing/ Merged latest trunk changes to tracing  
2787 6065 d 5 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 6094 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6115 d 7 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)
 
2712 6120 d 7 h decky /trunk/kernel/ prettyprint output  
2647 6167 d 2 h jermar /trunk/kernel/generic/src/mm/ Fix a bug in anonymous address space area sharing. Call the backend's share
function only if the source area is not already shared. Otherwise increment the
sh_info refcount. Without this fix, the kernel will try to recreate the pagemap
if three and more address space areas attempt to share the same data.
 
2556 6245 d 10 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2467 6353 d 3 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2222 6419 d 0 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2183 6422 d 5 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.
