QEMU implements the cycle count register read by
'Genode::Trace::timestamp()', but does not report a supported debug model
version for Cortex-A9.
Fixes#3154
1) A session request gets denied if there is no matching session policy.
(The <defaul-policy/> tag can be used for the former default behavior)
2) A session request gets denied if the MAC address is given through the
matching policy but this address cannot be allocated.
3) A session request gets denied if the MAC address is not given through the
matching policy and it is also not possible to allocate one.
Issue #3040
This is a follow-up commit of "base/core: use references instead of
pointers". Because the 'Rm_root::_upgrade_session' implementation
lacked the 'override' keyword, my overzealous change of the pointer
argument went unnoticed.
This commit fixes the depot_rom (cached_fs_rom) failure in Sculpt.
When cached_fs_rom attempted to create a new managed dataspace while the
RM session quota was depleted, it tried to upgrade the session (via
Rm_connection::create). However, the upgraded resources never reached
the actual session because the default 'Root_component::_upgrade_session'
was called instead of 'Rm_root::_upgrade_session'.
Issue #3135
This patch enhances the packet-stream API with the principle ability to
side-step the built-in implicity data-flow signals and manage the
signals manually. This allows for a more efficient batching of packet
processing.
Issue #3092
The 'tx_cap' RPC function is only used at session-creation time. For
this reason, it was not listed in the "official" RPC interface in
'block_session.h'. However, this makes the interface more obscure than
it needs to be. So this patch promotes it to a regular RPC function.
Issue #3092
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.
The most prominent changes are:
- Removing the use of base/printf.h
- Removing of the log backend for printf. The 'Console' with the
format-string parser is still there along with 'snprintf.h' because
the latter is still used at a few places, most prominently the
'Connection' classes.
- Removing the notion of a RAM session, which does not exist in
Genode anymore. Still the types were preserved (by typedefs to
PD session) to keep up compatibility. But this transition should
come to an end now.
- Slight rennovation of core's tracing service, e.g., the use of an
Attached_dataspace as the Argument_buffer.
- Reducing the reliance on global accessors like deprecated_env() or
core_env(). Still there is a longish way to go to eliminate all such
calls. A useful pattern (or at least a stop-gap solution) is to
pass the 'Env' to the individual compilation units via init functions.
- Avoiding the use of the old 'Child_policy::resolve_session_request'
interface that returned a 'Service' instead of a 'Route'.
Issue #1987
The notion of a RAM session does not exist anymore. Hence, we have to
adjust the name of 'init_env_ram_session'. Since this change modifies
the ABI, it comes as separate commit.
Issue #2407
Refactor the graphical terminal server to internally represent
characters as 16-bit codepoints and handle the duplex terminal stream as
UTF-8.
- Make the Codepoint class printable to the Output interface
- Decode data received at the Terminal session from UTF-8 to a 16-bit
character
- Pass 16-bit characters through terminal decoder and char-cell arrays
- Send Unicode through terminal session in a burst of UTF-8 bytes
Fix#3148
- support to create multiple vCPUs
- support to implement Vm_session methods client side within base library
- adjust muen specific virtualbox4 version to compile/link
Issue #3111
The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
Also added a report_rom for USB devices and let the driver report like
in a real scenario. Can also be used for debugging by setting
verbose="yes" in report_rom.
And most importantly: use the same size everywhere.
Note, this commit also configures the stack size of noux-process threads
to 64 KiB independently of the CPU architecture. The reason is the
increased stack usage because of the additional argument space in
Execve_child_env in syscall(SYSCALL_EXECVE), which crafts a child
environment on stack for the creation of the new child.
Fixes#3145.
