Originally the outgoing buffer was flush when the terminal was
detached. Since we cannot do that at this point, make the flushing
part of the common cleanup procedure.
Issue #3682.
Rather than calling 'ssh_disconnect' from within the Terminal session,
flag the detached terminal in the session and let the event loop do the
cleanup. Otherwise it might happen that the 'ep' (handling the Terminal
session) as well as the 'pthread.0' (executing the ssh event loop) end
up both triggering the cleanup concurrently.
Issue #3682.
In case of arm_v7a Kernel::call64 the syscall will use both r0 and r1 as
output registers. Unfortunately the inline asm does not reflect this and
only r0 is explicitly specified as output. GCC manages to produce output
which we'd like to see. Clang on the other hand takes adventage of the fact
r1 should not be touched by swi and produces fewer instructions which do
what the code describes, but not what we actually want.
Basically the code which we want and is generated by GCC is:
svc 0
mov r2, r0
mov r0, r1
mov r1, r2
bx lr
Clang on the other hand generates correct assembly given the code, but
incorrect given what the function is supposed to do:
svc 0
mov r1, r0
mov r0, #0
bx lr
Both GCC and clang generate the same, expected assembly output when r1
is marked as output register from the inline asm swi call.
Fixes#3951
Clang correctly asserts this private member variable is not used
anywhere in the code. I'm not sure what the intention of the code is,
might be this is a part of some unfinished feature. This patch just does
the minimum amount of work to allow the code to build with clang. If
required I can also drop the parent_levels constructor argument and
clean up the call sites.
Issue #3950
The msg argument in Genode::Rpc_dispatcher::_read_arg is not used. GCC
does not care about this, but clang does and prints a warning regaring
this. Silence it by removing unused argument name.
fixup! base: Silence unused arg warning in rpc_server.h
The CBE repository contained a lot of Genode-specific code despite the fact
that the CBE core logic is not bound to Genode in any way. Therefore the
Genode-specific CBE code is moved to the 'gems' repository to form part of
Genode mainline. The remaining CBE code becomes a port in Genode instead of
being invoked as sub-repository.
The commit combines the following work steps:
* add all files removed from CBE repository
* add CBE port files
* make all CBE libs and targets build again
* make all CBE run scripts succeed again
* make all CBE recipes build again
* make CBE autopilot succeed again
* let CBE autopilot use 'libsparcrypto' contrib dir and Genode build dir
instead of '.ci' dir in CBE contrib dir (remove '.ci' dir from CBE repo)
* let CBE autopilot always check for all ports
* make CBE autopilot directly executable
* fix license headers in all Genode CBE files
* remove unused VFS replay component
* remove unused CBE test
* remove unused external crypto
* remove unused files in run dir
* remove unused external trust anchor
* add cbe_tester test to autopilot list
* get rid of directories 'include/cbe_*' and 'include/utils'
Fixes#3937
The control area is constructed during session creation and the caller can
handle the Out_of_* exception by increasing the quota by the next attempt.
Fixes#3917
Log a warning when the lwIP VFS plugin queues a read while waiting
for an interface to become ready. By comparision the Lxip plugin
has the same behavior but a more verbose initialization process.
Fix#3920
Account for the situation where the driver is started while the HP
is already plugged in and configure the mixer accordingly.
Thanks to Peter for the patch.
Issue #3929.
Due to what seems like a copy-and-paste error, the wrong union member
was used to compare the label. Fortunately, as both structs have the
same memory layout that did not result in any issue.
Issue #3929.
Originally, the kernel code should have been executed within the
context of the main task like it is done in dde_linux. The initial
port of the HDA driver, however, did not required doing so and the
session called code directly.
When using USB device, that is no longer possible as we have to
suspend the execution during the execution of the kernel code. So
we pass in the audio data and schedule the kernel.
Fixes#3929.
This becomes necessary in case of the USB audio driver where we have
to wait for and query the function first.
That being said, alternatively we could also announce the session but
ignore any request until there is a device we can use.
Issue #3929.
With this commit the timer back-end uses the timeout framework to
schedule any occuring timeouts and for providing the current time.
For now there is only one timeout, the unsolicited azlia codec event
and therefore the timeout queue consists of solely one timeout object.
In addition a timer session is used for implementing 'delay()' where
we have to block until the delay is completed.
Issue #3929.
For historical reason the 'strlcpy' implemention was directly pull in
into the emulation environment. There is, however, no reason not to
use the contrib sources in the usual fashion.
Issue #3929.
Instead of the generic name, call the PCI driver 'pci_audio_drv'.
This is preliminary clean-up work before introducing the USB audio
driver.
Issue #3929.
The supported drivers so far exclusively used PCI and for practical
reasons the emulation environment was to tied to. To make future
addition of drivers that employ other transport busses easier, split
the bus handling into its own backend.
This is preliminary clean-up work before introducing the USB audio
driver.
Issue #3929.
* Updating the run script was missed in commit "dde_bsd: remove
configration attributes".
* Decrease output and input volume to "more sane" levels.
Issue #3929.
Updating the config and using its settings instead of only reporting
the new session allows to apply stored channel settings immediately.
In case of Sculpt this is useful when an existing launcher already
contains a valid config that sets the volume levels appropiately or
the 'recall_fs' is used.
Fixes#3930.
The _root, _gid and _uid private member variables are not used for
anything. GCC does not care, but clang likes to complain about things
like this.
Issue #3938
Right now the code marks specific instance of this function as noreturn.
It then tries to initialize it using a value that has the same type,
except for the noreturn part. GCC does not care, but clang complains this
technically assigns the value of entry from incompatible pointer type.
Fix this by defining Entry function as no return.
Issue #3938
The lambda function passed to Board::Vm_page_table_array does not
actually use "this" for anything. GCC does not warn about this, but
clang does. Remove the extra capture to make clang happy.
Issue #3938
GCC doesn't care, but clang complains if [[fallthrough]] is not followed
by a semicolon. Existing code is also not consitent in this regard. Lets
just fix it to make clang happy.
Issue #3938
When compiling this code, clang complains reference to 'Sandbox' is
ambiguous. It can either mean ::Sandbox namespace from
os/src/lib/sandbox/types.h, or Genode::Sandbox declared in
repos/os/include/os/sandbox.h. Since the code refers to ::Sandbox::Child
and its already in ::Sandbox namespace we can just drop "Sandbox" and
refer to just Child, which makes clang happy.
