1416 6557 d 20 h jermar /kernel/trunk/generic/ Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.		  
1415 6557 d 21 h jermar /kernel/trunk/generic/ Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount		  
1413 6558 d 8 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1411 6558 d 13 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1409 6559 d 7 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1387 6561 d 15 h jermar /kernel/trunk/generic/ Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used.		  
1382 6562 d 9 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6562 d 11 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1375 6563 d 18 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1364 6565 d 16 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6566 d 13 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1358 6566 d 13 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1342 6566 d 21 h jermar /kernel/trunk/generic/ Improve comments.  
1329 6568 d 13 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1327 6568 d 15 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1321 6568 d 21 h vana /kernel/trunk/generic/ force return 0 if no valid pointer in sysinfo syscall  
1318 6569 d 10 h vana /kernel/trunk/ Sysinfo userspace interface  
1317 6569 d 11 h vana /kernel/trunk/ System information tools  
1315 6569 d 13 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1310 6570 d 17 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.
