1474 6728 d 1 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6728 d 3 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6732 d 10 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6735 d 6 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.
 
1382 6739 d 2 h decky /kernel/trunk/ make hardware memory mapping more generic  
1303 6750 d 5 h palkovsky /kernel/trunk/arch/ zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas.
 
1292 6754 d 8 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1291 6754 d 9 h vana /kernel/trunk/arch/amd64/src/boot/ VESA detection failure fix on amd64  
1289 6754 d 10 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6754 d 11 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.
 
1281 6757 d 1 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1278 6757 d 5 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
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 12 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 9 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.
