1417 6558 d 6 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 6558 d 17 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 6558 d 18 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 6558 d 19 h jermar /kernel/trunk/generic/src/synch/ Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.		  
1413 6559 d 6 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1411 6559 d 10 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 6560 d 4 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1403 6561 d 18 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 6562 d 7 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 6562 d 9 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1387 6562 d 12 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 6562 d 13 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 6563 d 5 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1382 6563 d 6 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6563 d 8 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1375 6564 d 16 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1364 6566 d 13 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1362 6567 d 4 h vana /kernel/trunk/generic/src/syscall/ kernel changes for uspace FB driver  
1359 6567 d 10 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1358 6567 d 10 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1346 6567 d 17 h palkovsky /kernel/trunk/generic/src/ipc/ Small updates to IPC regarding AS_SEND.  
1342 6567 d 18 h jermar /kernel/trunk/generic/ Improve comments.  
1341 6568 d 6 h cejka /kernel/trunk/generic/src/main/ Added capability to register IRQs to tasks.  
1337 6568 d 12 h jermar /kernel/trunk/generic/src/adt/ Remove a misleading comment.  
1329 6569 d 10 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1327 6569 d 13 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1326 6569 d 13 h decky /kernel/trunk/generic/src/sysinfo/ fix conding style, make it compile again  
1325 6569 d 14 h vana /kernel/trunk/generic/src/sysinfo/ sysinfo warning patch  
1323 6569 d 18 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 6569 d 18 h vana /kernel/trunk/generic/src/sysinfo/ memory deallocation fix in sysinfo syscall handlers  
1321 6569 d 18 h vana /kernel/trunk/generic/ force return 0 if no valid pointer in sysinfo syscall  
1318 6570 d 7 h vana /kernel/trunk/ Sysinfo userspace interface  
1317 6570 d 9 h vana /kernel/trunk/ System information tools  
1315 6570 d 10 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1313 6570 d 15 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().		  
1310 6571 d 15 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1309 6572 d 9 h jermar /kernel/trunk/generic/src/mm/ On as_area_destroy(), mark the area as partial before unlocking and free its
structure after unlocking.		  
1306 6572 d 11 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6576 d 12 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.		  
1294 6577 d 16 h jermar /kernel/trunk/generic/src/syscall/ Remove unused variable.
