1429 6576 d 11 h jermar /kernel/trunk/generic/ Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired.		  
1428 6576 d 22 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.		  
1426 6576 d 23 h jermar /kernel/trunk/generic/src/mm/ Support for sharing address space areas backed up by ELF image.  
1425 6577 d 1 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6577 d 3 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.		  
1423 6577 d 7 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6579 d 0 h jermar /kernel/trunk/generic/ Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.

The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.		  
1416 6579 d 11 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 6579 d 12 h jermar /kernel/trunk/generic/ Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount		  
1414 6579 d 12 h jermar /kernel/trunk/generic/src/synch/ Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.		  
1413 6579 d 23 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1411 6580 d 4 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 6580 d 22 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1403 6582 d 11 h jermar /kernel/trunk/generic/src/mm/ Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes.		  
1396 6583 d 1 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1389 6583 d 2 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1387 6583 d 6 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.		  
1386 6583 d 6 h palkovsky /kernel/trunk/ Fixed mips bug fith TLS register not being properly saved on syscall context
switch.
Reverted SYS_IO, so that it could be used on machines without fb.		  
1383 6583 d 23 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1382 6584 d 0 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6584 d 1 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1375 6585 d 9 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1364 6587 d 7 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1362 6587 d 21 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1359 6588 d 4 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1358 6588 d 4 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1346 6588 d 11 h palkovsky /kernel/trunk/generic/src/ipc/ Small updates to IPC regarding AS_SEND.  
1342 6588 d 12 h jermar /kernel/trunk/generic/ Improve comments.  
1341 6589 d 0 h cejka /kernel/trunk/generic/src/main/ Added capability to register IRQs to tasks.  
1337 6589 d 5 h jermar /kernel/trunk/generic/src/adt/ Remove a misleading comment.  
1329 6590 d 4 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1327 6590 d 6 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1326 6590 d 6 h decky /kernel/trunk/generic/src/sysinfo/ fix conding style, make it compile again  
1325 6590 d 8 h vana /kernel/trunk/generic/src/sysinfo/ sysinfo warning patch  
1323 6590 d 12 h jermar /kernel/trunk/ Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.

Also add one HT configuration to hardware compatibility list.		  
1322 6590 d 12 h vana /kernel/trunk/generic/src/sysinfo/ memory deallocation fix in sysinfo syscall handlers  
1321 6590 d 12 h vana /kernel/trunk/generic/ force return 0 if no valid pointer in sysinfo syscall  
1318 6591 d 1 h vana /kernel/trunk/ Sysinfo userspace interface  
1317 6591 d 2 h vana /kernel/trunk/ System information tools  
1315 6591 d 4 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.
