Core on seL4 is configured to run on native hardware, so some static
allocators are bit over dimensioned. Some run scripts fail on qemu because
solely 64M are available in the system - adjust the affected scripts.
Issue #2044
This patch adds the methods 'sigh_ack_avail()' and
'sigh_ready_to_submit()', which are needed to build asynchronously
operating file-system clients.
Fixes#2023
Conveying the ROM filename as the final label element simplifies
routing policy and session construction.
Annotations by nfeske:
This commit also changes the ROM session to use base/log.h instead of
base/printf.h, which produced build error of VirtualBox because the
vbox headers have a '#define Log', which collides with the content of
base/log.h. Hence, this commit has to take precautions to resolve this
conflict.
The commit alse refines the previous session-label change by adding a
new 'Session_label::prefix' method and removing the use of 'char const *'
from this part of the API.
Fixes#1787
Session_label constructor now takes a bare string rather than a
serialized argument buffer.
Replace all instances of previous constructor with 'label_from_args'
function.
Issue #1787
This patch establishes the sole use of generic headers across all
kernels. The common 'native_capability.h' is based on the version of
base-sel4. All traditional L4 kernels and Linux use the same
implementation of the capability-lifetime management. On base-hw, NOVA,
Fiasco.OC, and seL4, custom implementations (based on their original
mechanisms) are used, with the potential to unify them further in the
future.
This change achieves binary compatibility of dynamically linked programs
across all kernels.
Furthermore, the patch introduces a Native_capability::print method,
which allows the easy output of the kernel-specific capability
representation using the base/log.h API.
Issue #1993
In addition to modernizing the component now also supports using
empty RAM dataspace as backing store.
For example to use an ISO file the component has to be configured
as follows:
! <config file="image.iso" block_size="2048"/>
To use a empty RAM dataspace that is 256MiB large and has a block
size of 4KiB the configuration looks like this:
! <config size="256M" block_size="4096"/>
Either 'size' or 'file' has to specified. If both are declared the
'file' attribute is soley evaluated.

Fixes#2031.
* remove all 'Genode::env()' calls
* use attached roms to read configuration
* use compoenent framework
* remove all PDBG, PINF, PWRN macros
Issue #1987Fixes#2019
* use Component::* instead of Server::*
* do not use old printf format anymore
* do not use old Genode::env()->heap() anymore
* avoid pointers where possible, and use references instead
* throw away the thread-safe variants of list and AVL tree,
nic_bridge became single-threaded in the past
* introduce Ram_session_guard instead of Allocator_guard

- platform_drv announces a separate "Acpi" session
- platform_drv waits for ROM "system" to change state to "acpi_ready"
- acpica waits for "Acpi" announcement
- acpica uses the platform driver via "Acpi" to reconfigure PCI devices
- acpica changes "system" state to "acpi_ready" after it ready with initialization
- platform_drv reacts on "system" state change to "acpi_ready" by announcing "Platform" session
- drivers start to operate as usual
Issue #2009
Replace 'attribute(...).has_value("yes")`
with 'attribute_value(..., false)'.
This allows for boolean configuration to be set with values such as
"true", "false", "yes", "no", or "1", "0".
Fixes#2002
A configuration policy must match against a policy node label,
label_prefix, or label_suffix atttribute. A fallback to
<default-policy/> is provided as a label wildcard.
Fixes#1901
The whole XML comment has to be parsed as one XML tag to support strange
but valid combinations like
<!---->
<!--invisible-tag></invisible-tag-->
Fixes#1424
Allocating a packet in the packet stream without a payload is not
allowed. Therefore we have to allocate CTRL message packets, that do
not have a payload, with a bogus length instead.
Directory_service::leaf_path returns a pointer offset from its argument
so pass member data rather than a constructor argument to leaf_path.
Issue #1775
This is an interim fix for solving the quota leakage problem of
the platform driver on x86 platforms. To properly fix that problem
one has to track which dataspaces where created by the platform driver,
so that freeing the dataspace and reversing the quota transfer is done
on correct dataspaces only.
Refer #1980
This patch removes the outdates doc/architecture.txt since the
topics are covered by the book. We keep repos/os/doc/init.txt
because it contains a few details not present in the book (yet).
The patch streamlines the terminology a bit. Furthermore, it
slightly adjusts a few source-code comments to improve the book's
functional specification chapter.
* Adds public timeout syscalls to kernel API
* Kernel::timeout installs a timeout and binds a signal context to it that
shall trigger once the timeout expired
* With Kernel::timeout_max_us, one can get the maximum installable timeout
* Kernel::timeout_age_us returns the time that has passed since the
calling threads last timeout installation
* Removes all device specific back-ends for the base-hw timer driver and
implements a generic back-end taht uses the kernel timeout API
* Adds assertions about the kernel timer frequency that originate from the
requirements of the the kernel timeout API and adjusts all timers
accordingly by using the their internal dividers
* Introduces the Kernel::Clock class. As member of each Kernel::Cpu object
it combines the management of the timer of the CPU with a timeout scheduler.
Not only the timeout API uses the timeout scheduler but also the CPUs job
scheduler for installing scheduling timeouts.
* Introduces the Kernel::time_t type for timer tic values and values inherited
from timer tics (like microseconds).
Fixes#1972
Evaluate fadt xml node in report from acpi_drv. If the io ports in the range
of 0xcf8+4 are necessary for the reset than the platform driver will
react on the 'system' state 'reset' and reboot.
