4490 5459 d 2 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3707 5628 d 2 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
2170 6253 d 23 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.		  
2071 6327 d 1 h jermar /trunk/ (c) versus (C)  
1891 6447 d 23 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 6449 d 1 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		  
1851 6476 d 7 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1787 6517 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6545 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 6551 d 20 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 6551 d 21 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1380 6569 d 2 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 6588 d 7 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
823 6669 d 21 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
788 6673 d 3 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 6679 d 4 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
741 6685 d 1 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6685 d 6 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6689 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
