Replace the use of the global 'core_env()' accessor by the explicit
delegation of interfaces.
- For allocating UTCBs in base-hw, 'Platform_thread' requires
a way to allocate dataspaces ('Ram_allocator') accounted to the
corresponding CPU session, a way to locally map the allocated
dataspaces (core's 'Region_map'), and a way to determine the
physical address (via 'Rpc_entrypoint') used for the initial
UTCB mapping of main threads. Hence those interfaces must be
passed to 'Platform_thread'.
- NOVA's pager code needs to look up 'Cpu_thread_component'
objects using a map item as key. The lookup requires the
'Rpc_entrypoint' that hold the 'Cpu_thread_component' objects.
To make this 'Rpc_entrypoint' available, this patch adds
the 'init_page_fault_handing' function.
- The 'Region_map_mmap' for Linux requires a way to look up
'Linux_dataspace' objects for given dataspace capabilities.
This lookup requires the 'Rpc_entrypoint' holding the dataspaces,
which is now passed to 'platform.cc' via the new Linux-specific
'Core_region_map::init' function.
Issue #5408
The recent changes of the GUI stack (proper accounting of cap and RAM
resources by the window manager and nitpicker, output buffered at the
server side) require quota adjustments at various GUI-related places.
Issue #5356
This patch enables basic use cases of the POSIX 'alarm' function, which
schedules the delivery of a SIGALRM signal after a specified amount of
seconds.
Issue #5337
triggered by the "system" ROM change. With this information the consumers
of the sleep_states report can determine, when the operation is finished.
Issue #5180
For pbxa9, Qemu is started with only 256 MiB for foc but with 768 MiB
for base-hw. By reducing the RAM quota for all start nodes within the
remote scenario, each component gets enough RAM quota to breathe.
Such messages can occur by chance when killing 'echo' while the program
blocks in an IPC call. It gets killed nevertheless. So the message does
not hint at a failure of the test.
The dynamic buffer allocation increases the RAM demand slightly beyond
1M on seL4. Use 2M, as is already the default in pkg/terminal_crosslink.
Issue #5135
This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.
With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.
Another use case is the 'tmpfile()' function.
Fixes#3577
* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.
Fixes#4922
