Now, we support multi-touch devices generating multi-touch events and
absolute-pointer devices simultaneously with multitouch="yes". Still,
multitouch="no" generates emulated absolute-pointer events for
multi-touch devices.
* remove all 'Genode::env()' calls
* use attached roms to read configuration
* use compoenent framework
* remove all PDBG, PINF, PWRN macros
Issue #1987Fixes#2019
The modular lx_kit seperates the required back end functionality of the
Linux emulation environment from the front end. Thereby each driver can
reuse specific parts or supply more suitable implementations by itself.
It is used to reduce the amount of redundant code in each driver.
The lx_kit is split into several layers whose structure is as follows:
The first layer in _repos/dde_linux/src/include/lx_emul_ contains those
header files that provide the structural definitions and function
declarations of the Linux API, e.g. _errno.h_ provides all error code
values. The second layer in _repos/dde_linux/src/include/lx_emul/impl_
contains the implementation of selected functions, e.g. _slab.h_
provides the implementation of 'kmalloc()'. The lx_kit back end API is
the third layer and provides the _Lx::Malloc_ interface
(_repos/dde_linux/src/include/lx_kit/malloc.h_) which is used to
implement 'kmalloc()'. There are several generic implementations of the
lx_kit interfaces that can be used by a driver.
A driver typically includes a 'lx_emul/impl/xyz.h' header once
directly in its lx_emul compilation unit. The lx_kit interface files
are only included in those compilation units that use or implement the
interface. If a driver wants to use a generic implementation it must
add the source file to its source file list. The generic
implementations are located in _repos/dde_linux/src/lx_kit/_.
The modular lx_kit still depends on the private _lx_emul.h_ header file
that is tailored to each driver. Since the lx_kit already contains much
of the declarations and definitions that were originally placed in
these private header files, those files can now ommit a large amount
of code.
Fixes#1974.
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs
The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax
<config>
<connector name="LVDS-11" width="1280" height="800" enabled="true"/>
</config>
Also, when enabled within the intel framebuffer driver configuration like
the following
<config buffered="yes"/>
a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.
The driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows
<connectors>
<connector name="LVDS-11" connected="1">
<mode width="1280" height="800" hz="60"/>
...
</connector>
...
</connectors>
The driver distributes the report only if this is stated within its
configuration, like the following
<config>
<report connectors="yes"/>
</config>
Fix#1764
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
Run script depending on VFS plugins (i.e., shared objects) like
vfs_jitterentropy.lib.so have to state this dependency rather the actual
binaries linked against libc. The latter introduces a library dependency
that is just not there. For example, the dependency on vfs_jitterentropy
is a result from the config node for libc which automatically loads the
plugin.
The wifi_drv now provides two reports. The first one contains all
accesspoints that were found while scanning the supported frequencies.
The second one reports the state of the driver, i.e., if it is
conntected to an accesspoint or not. In addition to that, the driver
now gets its configuration via a ROM session.
More detailed information are available in 'repos/dde_linux/README'.
Issue #1415.
Ported drivers list and extract all needed source files. This decouples
ports according to contrib sources and also enables us to revert lxip to
Linux version 3.9, while staying with 3.14 for usb.
Fixes#1285
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
