9af9dcc02c hw_x86_64: Reserve space for interrupt stack in mtc region
The interrupt stack must reside in the mtc region in order to use it for
non-core threads. The size of the stack is set to 56 bytes in order to
hold the interrupt stack frame plus the additional vector number that is
pushed onto the stack by the ISR.

Use parameter instead of class member variable because it would get

TODO: Set the base address using the 'tss' label. If the TSS descriptor
      format were not so utterly unusable this would be straightforward.
      Changes to the code that indirectly lead to a different location
      of the tss result in #GP since the base address will be invalid.

4417fe6201 hw_x86_64: Implementation of IA-32e paging
IA-32e paging translates 48-bit linear addresses to 52-bit physical
addresses. Translation structures are hierarchical and four levels deep.
The current implementation supports regular 4KB and 1 GB and 2 MB large
page mappings.

Memory typing is not yet implemented since the encoded type bits depend
on the active page attribute table (PAT)*.

For detailed information refer to Intel SDM Vol. 3A, section 4.5.

* The default PAT after power up does not allow the encoding of the
  write-combining memory type, see Intel SDM Vol. 3A, section 11.12.4.
* Add common IA-32e paging descriptor type:
    The type represents a table entry and encompasses all fields shared by
    paging structure entries of all four levels (PML4, PDPT, PD and PT).
* Simplify PT entry type by using common descriptor:
    Differing fields are the physical address, the global flag and the memory
    type flags.
* Simplify directory entry type by using common descriptor:
    Page directory entries (PDPT and PD) have an additional 'page size' field
    that specifies if the entry references a next level paging structure or
    represents a large page mapping.
* Simplify PML4 entry type by using common descriptor
    Top-level paging structure entries (PML4) do not have a 'pat' flag and the
    memory type is specified by the 'pwt' and 'pcd' fields only.
* Implement access right merging for directory paging entries
    The access rights for translations are determined by the U/S, R/W and XD
    flags. Paging structure entries that reference other tables must provide
    the superset of rights required for all entries of the referenced table.
    Thus merge access rights of new mappings into existing directory entries to
    grant additional rights if needed.
* Add cr3 register definition:
    The control register 3 is used to set the current page-directory base
    register.
* Add cr3 variable to x86_64 Cpu Context
    The variable designates the address of the top-level paging structure.
* Return current cr3 value as translation table base
* Set context cr3 value on translation table assignment
* Implement switch to virtual mode in kernel
    Activate translation table in init_virt_kernel function by updating the
    cr3 register.
* Ignore accessed and dirty flags when comparing existing table entries
    These flags can be set by the MMU and must be disregarded.

    6.3.1.
* Add Idt class:
  * The class Genode::Idt represents an Interrupt Descriptor Table as
    specified by Intel SDM Vol. 3A, section 6.10.
  * The setup function initializes the IDT with 20 entries using the ISR
    array defined in the isr.s assembly file.

    The Idt::setup function is only executed once on the BSP.

dd47129bef nic session: link-state change handling
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.

The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.

The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.

dac3efcc02 vbox: replace too strict assertion with debug message
The 'continue_hw_accelerated' assertion at the end of the recall handler
can fail in situations which are not problematic, for example if the
'Timer' thread has set the 'VMCPU_FF_TIMER' flag in the meantime and
requested a recall afterwards. Since we don't know for sure if a recall is
requested for the other flags as well, the assertion gets replaced by a
debug message, which gets printed if any of the 'not yet verified as safe'
flags is set.

9b7e0ce0a5 part_blk: add GPT support
The GUID partition table (GPT) is primarily used by systems using
(U)EFI and is a replacement for the legacy MBR. For now, the current
implementation is able to address up to 128 GUID partition entries
(GPE).

To enable the GPT support in 'part_blk' it has to be configured
accrodingly:

! <start name="part_blk">
! [...]
!   <config use_gpt="yes">
! [...]
! </start>

If 'part_blk' is not able to find a valid GPT header it falls back
to using the MBR.

Current limitations:

Since no endian conversion takes place it only works on LE platforms
and of all characters in the UTF-16 encoded name field of an entry
only the ones included in the ASCII encoding are printed. It also
ignores all GPE attributes.

1f7fd647da vbox: wait longer for stable timer state
Some functions in the time manager, for example 'TMTimerSet()' and
'TMTimerStop()' let VirtualBox abort with a failed assertion if the timer
does not change to a 'stable' state after 1000 calls of a mixture of
'yield' and 'sleep'. On Genode, this happens sometimes when the 'EMT'
thread is executing 'TMTimerSet()' and gets interrupted by the 'TAP'
thread, which calls 'TMTimerStop()' and waits for the 'EMT' thread to
finish setting the timer. Since the 'EMT' thread has the lowest priority,
1000 retries can be too few. Without the assertion, these functions would
return an error code, which is often ignored by the caller, so it seems
safer to keep retrying until the function can return successfully.

8e2b4d6f45 hw: extend kernel interrupt class
The generalization of interrupt objects in the kernel and the use of
C++ polymorphism instead of explicitely checking for special interrupts
within generic code (Cpu_job::_interrupt) enables the registration of
additional interrupts used by the kernel, which are needed for specific
aspects added to the kernel, like ARM hardware virtualization interrupts.

* Introduce generic base class for interrupt objects handled by the kernel
* Derive an interrupt class for those handled by the user-land
* Implement IPI-specific interrupt class
* Implement timer interrupts using the new generic base class

0836726df2 hw: use one IRQ for all cpus to send IPIs
Until now, one distinct software generated IRQ per cpu was used to
send signals between cpus. As ARM's GIC has 16 software generated
IRQs only, and they need to be partitioned between secure/non-secure
TrustZone world as well as virtual and non-virtual worlds, we should
save them.

a838b6a657 noux: add local nanosleep(2) and sleep(3)
Up to now Noux used the libc sleep functions, which actually is not
possible because the _nanosleep() function implemented by our libc
creates a new thread to handle the timeout. Noux childs may have
only one thread, e.g., the main thread, though. To fix this issue
sleeping is now handled directly by Noux. It is implemented by calling
select(2) with a timeout. This fix is needed for mutt(1), which calls
sleep when it prints a notification for the user.

a0abb093ed Remove output-section fill from linker scripts
The linker scripts use to fill alignment gaps within the text section
with the magic value 0x90909090, which correponds to the opcodes of four
nop instructions on x86. This patch removes this value because it
apparently solves no problem. If, for some reason (e.g., due to a dangling
pointer) a thread executes instructions within alignment paddings, NOP
instructions are not any better than any other instruction. The program
will eventually execute the instructions after the padding, which is
most likely fatal. It would be more reasonable to fill the padding with
the opcode of an illegal instruction so that such an error can be
immediately detected. That said, I cannot remember a single instance,
where the fill value has helped us during debugging.

Even if the mechanism served a purpose on x86, it is still better to
remove it because it does not equally work on the other architectures
where the linker scripts are used. I.e., on ARM, the opcode 0x90909090
is not a NOP instruction.

When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.
