1290 6626 d 22 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)		  
1288 6627 d 0 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.		  
1280 6629 d 16 h jermar /kernel/trunk/arch/ Get rid off obsolete ddi_int_control_arch() on ia64, sparc64 and ppc32.  
1265 6630 d 23 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1227 6638 d 20 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 6638 d 23 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1221 6639 d 13 h decky /kernel/trunk/ printf-related and other code cleanup  
1210 6640 d 23 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1196 6645 d 23 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6648 d 3 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6648 d 18 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.		  
1168 6652 d 17 h vana /kernel/trunk/ Thread RSE support completion (kernel)  
1138 6665 d 19 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1124 6669 d 1 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1121 6669 d 15 h jermar /kernel/trunk/ Small textual changes.  
1104 6670 d 19 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1080 6675 d 18 h jermar /kernel/trunk/arch/ia64/src/mm/ Fix double page_table_unlock() in ia64 tlb.c.  
1078 6675 d 18 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6676 d 10 h jermar /kernel/trunk/ Support for user space threads.  
1059 6676 d 16 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.		  
1056 6676 d 18 h jermar /kernel/trunk/arch/ia64/src/ Slightly optimized version of ivt.S.  
1053 6676 d 19 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1044 6676 d 23 h jermar /kernel/trunk/ Page table locking.  
1039 6677 d 0 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1023 6677 d 18 h vana /kernel/trunk/ Itanium FPU active context switch  
993 6678 d 16 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.		  
979 6678 d 22 h vana /kernel/trunk/arch/ia64/ Itanium FPU context save/restore  
962 6679 d 15 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.
Fix user stack initial address.		  
958 6679 d 16 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
947 6680 d 2 h vana /kernel/trunk/ Better purge page selection.  
945 6680 d 15 h vana /kernel/trunk/arch/ia64/  
944 6680 d 15 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
938 6680 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6680 d 19 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
928 6680 d 23 h vana /kernel/trunk/ Itanium tlb_invalidate_all

921 6683 d 18 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6683 d 23 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
916 6686 d 1 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6686 d 2 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.
