This patch augments the existing session/session.h with useful types for
the session creation:
* The new 'Insufficient_ram_quota' and 'Insufficient_cap_quota'
exceptions are meant to supersede the old 'Quota_exceeded' exception
of the 'Parent' and 'Root' interfaces.
* The 'Session::Resources' struct subsumes the information about the
session quota provided by the client.
* The boolean 'Session::Diag' type will allow sessions to operate in a
diagnostic mode.
* The existing 'Session_label' is not also available under the alias
'Session::Label'.
* A few helper functions ease the extraction of typed session arguments
from the session-argument string.
Issue #2398
This patch upgrades the cap-space slab only if the kernel runs out of
entries, instead of consuming as much PD-session quota as possible.
Until now, the behavior worked well because the cap-space slab was the
only consumer of PD-session quota. However, once we start accounting all
PD session meta data - and eventually merging the PD and RAM services -
the aggressive scheme stands in the way.
Issue #2398
This accessor is useful to eagerly expand the slab with new slab blocks,
side stepping the slab's built-in policy for the allocation of new slab
blocks.
This is particularly important when using the slab for allocating the
cap space meta-data for the base-hw kernel. To guarantee that the slab
gets never exhausted in the kernel, it is expanded before entering the
kernel.
With the introduction of the 'Out_of_caps' exception type, the slab
needs to consider exceptions during the call of '_new_slab_block' by
reverting the 'nested' state.
The old download location is very shaky resp. currently unavailable and
also other projects (e.g., Gentoo and Linux From Scratch) use this
location. Note, the archive hash does _not_ change.
By building the posix library as shared object with an ABI, we
effectively decouple posix-using programs from the library
implementation (which happens to depend on several os-level APIs such as
the VFS).
This commit moves the headers residing in `repos/base/include/spec/*/drivers`
to `repos/base/include/drivers/defs` or repos/base/include/drivers/uart`
respectively. The first one contains definitions about board-specific MMIO
iand RAM addresses, or IRQ lines. While the latter contains device driver
code for UART devices. Those definitions are used by driver implementations
in `repos/base-hw`, `repos/os`, and `repos/dde-linux`, which now need to
include them more explicitely.
This work is a step in the direction of reducing 'SPEC' identifiers overall.
Ref #2403
causes the rem timer callback pending check to run more often (every 1 ms
instead 10 ms). This is essential to met the timeout requirements of the
audio backend, which must be checked&run every 5ms.
This patch adjusts the interactive scenarios of the gems repository to
use the depot. This has three immediate benefits. First, once the depot
is populated with binary archives, the start time of the scenarios
becomes very quick because most dependency checks and build steps are
side-stepped. Second, the run scripts become more versatile. In
particular, run scripts that were formerly supported on base-linux only
(nit_fader, decorator, menu_view) have become usable on all base
platforms that have a 'drivers_interactive' package defined. Finally,
the run scripts have become much shorter.
Issue #2339
This way, files copied from the depot are incorporated in addition to
the files explicitly specified as boot modules.
The patch also adds an automatic check for the validity of the XML
syntax of boot modules ending with '.config'.
Issue #2339
Run scripts can use the new 'import_from_depot' function to incorporate
archive content from the depot into a scenario. The function must be
called after the 'create_boot_directory' function and takes any number
of pkg, src, or raw archives as arguments. An archive is specified as
depot-relative path of the form <user>/<type>/name. Run scripts may
call 'import_from_depot' repeatedly.
An argument can refer to a specific version of an archive or just the
version-less archive name. In the latter case, the current version (as
defined by a corresponding archive recipe in the source tree) is used.
If a 'src' archive is specified, the run tool integrates the content of
the corrsponding binary archive into the scenario. The binary archives
are selected according the spec values as defined for the build directory.
As of now, only x86_32 and x86_64 are supported by the 'depot_spec'
function.
