1686 6544 d 22 h decky /kernel/trunk/ update mips32 boot loading API  
1678 6545 d 17 h jermar /kernel/trunk/ Load up to 8 userspace tasks on mips32.  
1642 6547 d 22 h vana /kernel/trunk/arch/mips32/src/ System info about machine  
1627 6548 d 9 h palkovsky /kernel/trunk/arch/mips32/ Fixed size of mips processes, they are larger now.  
1615 6548 d 16 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1595 6549 d 1 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1587 6549 d 15 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.		  
1537 6552 d 8 h palkovsky /kernel/trunk/ Added tetris to  
1511 6552 d 18 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1474 6554 d 11 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6555 d 10 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1434 6557 d 15 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1432 6557 d 21 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1423 6558 d 19 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6561 d 16 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.		  
1396 6564 d 13 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().		  
1386 6564 d 18 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.		  
1354 6569 d 18 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1334 6571 d 1 h jermar /kernel/trunk/ Force mips32 frame buffer access to be always big endian.

Fix vmaxlma.c warning when building ia64.		  
1332 6571 d 12 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1293 6580 d 18 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6580 d 21 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.		  
1278 6583 d 14 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1260 6586 d 11 h palkovsky /kernel/trunk/ Small fixes.  
1258 6586 d 11 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.		  
1227 6592 d 17 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.		  
1223 6592 d 20 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6593 d 9 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1221 6593 d 10 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6593 d 15 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1196 6599 d 20 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6602 d 0 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6602 d 15 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1185 6602 d 18 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6602 d 18 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6604 d 0 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1135 6621 d 10 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1126 6622 d 21 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1122 6623 d 8 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6623 d 11 h jermar /kernel/trunk/ Small textual changes.
