1263 6758 d 11 h jermar /kernel/trunk/arch/ When seting TSS limit, take the mandatory extra ending byte with all bits set into account.
Align this group of eight bits on byte boundary.
 
1261 6759 d 10 h jermar /kernel/trunk/arch/ Fixes in amd64 and ia32 ddi_iospace_enable_arch().  
1258 6760 d 1 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.
 
1257 6760 d 8 h jermar /kernel/trunk/arch/ Initialize amd64 and ia32 task iomapver generation counter.  
1256 6760 d 8 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
 
1255 6760 d 11 h jermar /kernel/trunk/arch/ I/O Permission bitmap fixes. The trailing all-one sequence must be 8 bits long.
Update TSS limit in a proper way.
 
1252 6760 d 12 h palkovsky /kernel/trunk/arch/amd64/src/ Fix amd64 SMP boot when tss for AP CPU gets allocated in memory >20MB.  
1251 6761 d 8 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.
 
1247 6762 d 6 h vana /kernel/trunk/arch/amd64/src/smp/ Same 24 - > 32 bit lgdt patch on amd64 arch. Now both ia32 and amd64 platforms are able to have AP GDTs in all lowest 4GB of physicall memory.  
1242 6763 d 1 h jermar /kernel/trunk/arch/ This time really fix wrong definition of K_DATA_START.  
1241 6763 d 1 h jermar /kernel/trunk/arch/ Fix K_DATA_START section definition.  
1227 6766 d 7 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 6766 d 10 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1221 6767 d 0 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6767 d 5 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6772 d 6 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
 
1201 6772 d 7 h jermar /kernel/trunk/arch/ Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit.
 
1196 6773 d 9 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1191 6775 d 14 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1190 6776 d 4 h jermar /kernel/trunk/arch/ Move updating I/O Permission bitmap to before_task_runs_arch().
