1415 6564 d 20 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 6565 d 7 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1411 6565 d 12 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 6566 d 6 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1387 6568 d 14 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 6569 d 8 h decky /kernel/trunk/ make hardware memory mapping more generic  
1380 6569 d 9 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1375 6570 d 17 h jermar /kernel/trunk/generic/ Fix race in condition variables.  
1364 6572 d 15 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6573 d 11 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1358 6573 d 12 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1342 6573 d 19 h jermar /kernel/trunk/generic/ Improve comments.  
1329 6575 d 12 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1327 6575 d 14 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1321 6575 d 19 h vana /kernel/trunk/generic/ force return 0 if no valid pointer in sysinfo syscall  
1318 6576 d 9 h vana /kernel/trunk/ Sysinfo userspace interface  
1317 6576 d 10 h vana /kernel/trunk/ System information tools  
1315 6576 d 11 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1310 6577 d 16 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1306 6578 d 13 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1297 6582 d 13 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.		  
1293 6584 d 14 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6584 d 17 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1284 6586 d 21 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6587 d 7 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1278 6587 d 10 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1271 6587 d 17 h cejka /kernel/trunk/ All the *printf functions ported to kernel.
Comments updated.
Printf1 test uses snprintf to test printing to a string.		  
1264 6588 d 16 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1258 6590 d 7 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.		  
1253 6590 d 17 h jermar /kernel/trunk/generic/include/syscall/ Replace old name of SYS_IOSPACE_ENABLE with a new one.  
1251 6591 d 14 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.		  
1239 6593 d 11 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.		  
1238 6593 d 12 h jermar /kernel/trunk/generic/ 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.		  
1236 6593 d 17 h jermar /kernel/trunk/generic/ Add frame_reference_add().  
1235 6593 d 17 h jermar /kernel/trunk/generic/ 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.		  
1229 6595 d 16 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 6596 d 13 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.		  
1224 6596 d 15 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1223 6596 d 16 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1221 6597 d 6 h decky /kernel/trunk/ printf-related and other code cleanup
