d0d5ec92b6 ports/libports: Use repository-local PWD
The PWD variable contains the current working directory of the original
location where 'make -C' is executed, not the directory specified as
argument of '-C'. The tools referenced by ports/libports, however,
expect PWD to point to the root of the respective repository.

9d778a658d ports/libports: Avoid multi-target rules
This patch splits the download of signatures from the download of the
archive to improve robustness. This way, signature files will be
downloaded even if the corresponding archive is already in place.

179f742924 ports/libports: Handle failed integrity checks
This patch makes the handling of failed integrity checks of 3rd-party
packages more robust. Previously, a once failed 'make prepare PKG=curl'
would not leave any trace of the verification state. Hence, a successive
attempt to perform the 'make prepare' step again succeeded even if the
signature check failed.

To solve this problem, the outcome of a successful signature check is
represented by a tag file called 'download/<archive-name>.verified'.
Because the rule for extracting the archive depends on the .verify tag
file, the extraction step is not performed until the signature check
succeeds.

314d5c0975 liquid_fb: dynamic reconfiguration support
With this patch, 'liquid_framebuffer' can be reconfigured at runtime.
The configuration arguments are now provided as XML attributes, matching
those for 'nit_fb'. Furthermore, two new configuration options are added:

<config ...
  resize_handle="off" - show/hide a resize handle widget in the lower
                        right window corner
  decoration="on"     - show/hide window decoration

33c5469b92 vancouver: Improved PS/2 mouse backend
The previous version of the PS/2 mouse backend manged mouse motion
events in a strange way, effectively throwing away most information
about the motion vector. Furthermore, the tracking of the mouse-button
states were missing. So drag-and-drop in a guest OS won't work. The new
version fixes those issues. For the transformation of input events to
PS/2 packets, a the Genode::Register facility is used. This greatly
simplifies the code.

fae63f4fa9 Merge base libraries into a single library
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.

Hereby, the base libraries have been reduced to the following few
libraries:

- startup.mk contains the startup code for normal Genode processes.
  On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
  identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
  processes

Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.

cbf4a7b0c3 vancouver: Disk support
Vancouver can now assign block devices to guests using the Block
interface. The machine has to be configured to use a specified drive,
which could be theoretically routed to different partitions or services
via policy definitions. Currently the USB driver only supports one
device. Genode's AHCI driver is untested.

If the session quota is too low, random pagefaults can occur on the
stack.

According to @Nils-TUD, it is necessary to protect the DiskCommit
messages with a lock against deadlocking with the timer. Observations
showed that this mitigates some problems with Gentoo on real hardware.

1c447d98e9 vancouver: Network support
Vancouver is now able to use the Intel 82576 device model from NUL to
give VMs access to the network via the nic_bridge service. In order to
integrate the device model, it had to be renamed to i82576 due to XML
limitations. This is done by a patch applied via the 'make prepare'
mechanism.

Although current network card models in Vancouver panic if they can't
get a MAC address, the OP_GET_MAC hostop now fails gracefully in the
case where no nic_drv or nic_bridge is available.

1ca0a66ea9 vancouver: Console support
The guest VM can now be provided with a framebuffer and keyboard input.

Mouse positioning of the guest is a problem. Because the PS2 model applies
some calculations to the movement values, it can happen that overflows mess
with the cursor.  Therefore the handling was changed and only movements of 1
and -1 are sent.  Since absolute positioning is not possible with PS2, we
have to live with this limitation until USB HID is implemented.

For the framebuffer size in Vancouver the configuration value in the machine
XML node is used.  It is possible to map the corresponding memory area
directly to the guest, regardless if it is from nitpicker,
liquid_framebuffer or vesa_drv.  The guest is provided with two modes (text
mode 3 and graphics mode 0x114 (0x314 in Linux).

Pressing LWIN+END while a VM has focus resets the virtual machine. Also,
RESET and DEBUG key presses will not be forwarded to the VM anymore.
It is possible to dump a VM's state by pressing LWIN+INS keys.

The text console is able to detect idle mode, unmaps the buffer from the
guest and stops interpreting.  Upon the next pagefault in this area, it
resumes operation again.  The code uses a simple checksum mechanism instead
of a large buffer and memcmp to detect an idle text console.  False
positives don't matter very much.

0539c7180b Noux: add Io_receptor to SYSCALL_SELECT + bugfix
The Io_receptor is now used to unblock certain I/O channels from lwip's
callback-function.

the ready-to-write ones.

837f913094 Noux: more useful gettimeofday() implementation
There are certain programs that need gettimeofday(), e.g.
network-related tools like ping(1) etc. but also filesystem-related
programs like find(1) etc. and of course time-related programs like
date(1).

As there is currently no interface in Genode for actually using clock
devices like RTC on x86 (though there is a driver for it) we "abuse"
the timeout_scheduler thread to at least provide flow-of-time.

Noux: add clock_gettime() implementation

For now, only CLOCK_SECOND is supported.

Explanation why --disable-rpath-hack is needed:

When building on pistachio_x86 $(LDFLAGS) contains '-L[...]/l4/lib'
which will be transformed by autoconf to '-rpath [...]/l4/lib'.
Now the problem at hand is that we pretend to be FreeBSD when we are
actually not. So autoconf assumes it is valid to use '-path'  when it
is actually not.

Also we use zlib for (de)compressing gzipped streams/files instead of
calling gzip as this currently somewhat buggy.

a77c3dffd0 Noux: add user information support (struct passwd)
There are certain programs which need the information that is stored in
'struct passwd'. This commit introduces configurable user information
support to NOUX.

One can set the user information via <user> in NOUX config:

! <config>
!   <user name="baron" uid="1" gid="1">
!     <shell name="/bin/bash" />
!     <home name="/home" />
!   </user>
! [...]
! </config>

When <user> is not specified default values are used. Currently these
are 'root', 0, 0, '/bin/bash', '/'.

Note: this is just a single user implementation because each Noux instance
has only one user or rather one identity and there will be no complete
multi-user support in Noux. If you need different users, just start new
Noux instances for each of them.

ae524e4beb Noux: add timeout handling to select()
Previously there was not actual timeout handling. If a select() call
set an timeout it would be set to zero instead and was always handled
as blocking i/o. While this works fine for file descriptors which
will be triggerd externally (for example vim through terminal i/o) it
does not work at all for socket descriptors and network operations in
general.

So this commit introduces proper timeout handling and changes the
behaviour of SYSCALL_SELECT so that it now returns more than just
one descriptor at a time.

noux/minimal and noux/net now depend on thread and alarm libraries.

libc version, which has a Noux-specific implementation in the 'libc_noux'
plugin.

Fixes #324.

a7235d2411 NOVA: Use Genode interfaces to bootstrap Vancouver
Since no kernel objects can be created anymore outside Genode::core,
the Vancouver port must be adjusted to use solely the Genode interfaces.

The Vcpu_dispatcher creates all portals via the cpu_session interface and
uses the feature to setup a specific receive window during a IPC (the
cap_session::alloc IPC) to place to be received/to be mapped capability
(virtualization exception portal) at the designed indexes.

The actual vCPU thread extends from a normal Genode::Thread and extends it
by specific vCPU requirements, which are a larger exception base window and
the need by Vancouver to place the SM and EC cap at indexes next to each other.

ae6257dce1 Use NOVA microkernel from github, add 64bit
Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode

Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.

On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.

In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)

This patch adds a new "terminal" file system type to Noux, which allows to
create a "character device" file that is connected to a Genode 'Terminal'
service.

The 'Terminal' session created by the file system has the label
"noux(terminal_fs)" to distinguish it from the 'Terminal' session
created by Noux itself.

288fd4e56e Add support for allocating DMA memory
This patch extends the RAM session interface with the ability to
allocate DMA buffers. The client specifies the type of RAM dataspace to
allocate via the new 'cached' argument of the 'Ram_session::alloc()'
function. By default, 'cached' is true, which correponds to the common
case and the original behavior. When setting 'cached' to 'false', core
takes the precautions needed to register the memory as uncached in the
page table of each process that has the dataspace attached.

Currently, the support for allocating DMA buffers is implemented for
Fiasco.OC only. On x86 platforms, it is generally not needed. But on
platforms with more relaxed cache coherence (such as ARM), user-level
device drivers should always use uncacheable memory for DMA transactions.
