Rename SYS_AS_AREA_SHARE_APPROVE and SYS_AS_AREA_SHARE_PERFORM, resp., to
SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND, resp. in syscall_t.
Fix prototype of as_area_send() to take only base address of the address
space area as a parameter and read size and flags from the address space
area found at this base address.

Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
1227
6643 d 11 h
jermar
/kernel/trunk/
Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
1178
6654 d 11 h
jermar
/kernel/trunk/
Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.

Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.
1070
6680 d 17 h
jermar
/kernel/trunk/
More checks for address space area conflicts.
1048
6681 d 13 h
jermar
/kernel/trunk/generic/
Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.
1044

Page table locking.
1026
6682 d 3 h
jermar
/kernel/trunk/generic/
Support only anonymous address space areas.
977
6683 d 13 h
jermar
/kernel/trunk/
Add sys_mremap() syscall.
973

/kernel/trunk/generic/
Added simpler userspace starting.

Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.

6717 d 4 h
jermar
/kernel/trunk/
Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.

Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.

6720 d 9 h
jermar
/kernel/trunk/
Move list and fifo data types to adt/.
778
6721 d 8 h

/kernel/trunk/
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
755
6726 d 3 h
jermar
/kernel/trunk/
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.
754
6726 d 4 h
jermar
/kernel/trunk/generic/
Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.
